F-15 Strike Eagles Over Saudi Arabia: Then And Now
Richard Crandall compares the Strike Eagle he flew 25 years ago in Desert Storm to those screaming over the Kingdom today.
By Tyler RogowayJuly 12, 2016
Tyler Rogoway
Richard Crandall started his Air Force flying career in the F-111 Aardvark, but found himself in the cockpit of the mighty F-15E Strike Eagle, the service’s newest jet, during Operation Desert Storm. Although F-15C/D Eagles were already a staple in the Royal Saudi Air Force by the time Desert Storm kicked off, the Strike Eagle would eventually find its way into the Kingdom’s aerial arsenal in the form of the F-15S. Today, Saudi Arabia flies around 70 of these jets, and soon they will receive 84 F-15SAs, the most advanced Strike Eagle derivative ever produced.
Now Crandall serves as a contractor with the Royal Saudi Air Force, where he puts his experiences flying and fighting in the F-15E “Mud Hen” to use. Below, read Crandall's perspective detailing how the Strike Eagle first arrived in Saudi Arabia, how they were baptized by fire during Desert Storm, and how they differed from the Strike Eagles flown today.

Strike Eagles arrive in the Kingdom
Saudi Arabia has flown the F-15 Eagle for a very long time. The Kingdom bought the Eagle and started flying them long before Desert Storm in 1991. Royal Saudi Air Force pilots flying the F-15Cs even shot down two Iraqi fighters during the war.
Iraq invaded Kuwait on August 2, 1990. In that same month, the USAF’s newest and most potent strike fighter, F-15E Strike Eagle, landed in Saudi Arabia for the first time, but its stay was brief. The jets were only on the ground for a few hours at King Abdulaziz Air Base in Dharan. They were refueled and immediately departed for Thumrait, Oman.
At the time, their presence in the Kingdom was considered too offensive, and some worried it might result in Iraq immediately crossing the border into Saudi Arabia. The only way to stop them was deploying the Saudi Army and the 82nd Airborne. The 82nd Airborne would have fought valiantly, but its anti-armor capability wasn't there, and it would have been a speed bump under Saddam Hussein's armored forces.
For the next six months, the USAF’s first operational F-15E unit, the 336th Fighter Squadron “Rocketeers,” flew from Oman, while the great military buildup leading up to Desert Storm—called Desert Shield—went on in Saudi Arabia and around the region. Finally, in December, the word came down that the “World Famous Fighting Rocketeers” and their mighty F-15Es would deploy to Al Kharj Air Base (which we called Al’s Garage).
There we would join up there with the 335th Fighter Squadron “Chiefs” which also hailed from Seymour Johnson AFB. The Chiefs proudly claimed to be “The World’s Largest Distributor of MiG Parts” from back when they flew the F-86 during the Korean War, and they had an impressive kill record.

The Genesis of the Strike Eagle
The Strike Eagle was an adaptation of an incredible Air-to-Air machine, the F-15A/B/C/D, and it still has the best kill-to-loss ratio of any fighter aircraft ever (debatably, 98 to 1). It was designed and first flew in the early 1970s. It thrives at medium-altitude, with a complex airfoil that gave it outstanding maneuverability unmatched by any other aircraft. It was so big that many classes at Luke AFB had their class photos shot with the entire class standing on top of the airplane in tennis outfits—it became known as the “flying tennis court.” As for its large visual signature, real fighter pilots aren’t afraid of being seen: We kill you as we spit in your face.
During the late 70s and early 80s, the F-111 was getting old, although I almost laugh at that now, since the oldest flying F-15s are approaching 40. In 1980’s, when the USAF started to pursue what became the Strike Eagle, the oldest F-111 was only about 20 years old.
The F-111 was a great penetration low-level day/night bomber but it had almost no air-to-air capability. I loved flying it, but it could be out-turned by everything. Low and fast it excelled marvelously. It was, however, an absolute maintenance nightmare. I think from my days on the staff at Air Combat Command at Langley AFB (if a judge told me to choose to serve on the staff in a non-flying job or go to prison—not sure what I'd do...) that the F-111 was 9% of the Tactical Air Force, but took up 25% of the budget. With this in mind, the USAF held a competition between a really cool looking delta-winged F-16XL and a heavily modified F-15D. The air-to-ground optimized Eagle was chosen.
(Author’s note: Israel was actually the first to put the concept of an air-to-ground F-15 to use operationally. Read all about it here.)
What made the “Mud Hen” special
The multi-role F-15E retained 100% of the capabilities of the “not a pound for air-to-ground” F-15C, sort of. They added two conformal fuel tanks (CFTs) on the sides of the fuselage that gave it a lot more gas, about an extra 8,500lbs of go-juice to be exact, but they also added weight and drag.
The CFTs could also carry up to 6,000lbs of weapons per side, or two 2,000lb weapons per side. Thus, a clean F-15E with CFTs up against an F-15C with two wing tanks would be hard pressed to win, especially as all that the F-15C driver did was live, eat, breathe air-to-air. We in the Strike Eagle community did 90% air-to-Ground and about 10% air-to-air. That ratio has varied over the years, but for us who went to Saudi Arabia so long ago, we were focused on bombs. The light grey guys (the F-15C wears a lighter paint scheme) can’t even say the word bombs, they call it “the B word” they hate it so much. They may be able to kill them one by one, but we can do that too plus we take the bad guys out by the hundreds with our payloads.
The best thing about the F-15E? It worked. You turned the radar on and it stayed on. You didn’t lose the INS (Inertial Navigation System) if you hiccupped. The TFR (Terrain Following Radar) always worked. Plus we had an IR (infrared) picture in our wide-screen HUDs that the light grey types lusted after, the massive HUD not the IR. Their’s was tiny and shriveled in comparison.
We had a WSO (Weapons Systems Officer). The light grey guys hate the idea of having company in the cockpit. That was life for us. Personally I found that when I worked with a good WSO I could fight better than by myself. I think I would have been a better pilot if forced to do it all by myself but when you put me with a WSO, we as a crew were better than I ever could have been with me by myself. Plus a huge advantage here, when I screwed up and was called into the boss’s office to be screamed at it hurt less as he was screaming at two of us instead of me alone. Misery loves company.

The F-15E had a fantastic advance know as Synthetic Aperture Radar (SAR). Basically a bunch of nerdy skinny guys with coke bottle eyeglasses and pocket protectors found that if they had the radar sweep back and forth a couple of times and then analyzed all of the pictures, checked them twice to see if we were naughty or nice, and then took the cube root of the square of the phase of the moon, that they could give us a picture of the ground that looked like it was taken from a satellite. It was incredible. Fences looked like fences. Buildings were square instead of blobs. Radar scope interpretation became much-much easier and bombing accuracy became much better.
To use the Synthetic Aperture Radar we had to move sideways to the target for a couple of sweeps. The greater the angle off the nose the area was we wanted to look at the faster the picture and the more accurate the radar picture was. This totally changed our target area behavior. In the F-111 you flew straight at the target as the WSO used the radar to find it. In the Strike Eagle we would fly at an angle to the target and turn direct only after the WSO found and designated it.
This was not that big of a deal really. We had to maneuver anyway to get minimum safe distance between each striking aircraft so we just integrated the need to map the target into our plan to attack from different directions at different times.
We would run in low. The F-15E could fly TFR down to 100 feet though I only used 200 feet to my eternal regret. Woulda-coulda-shoulda gone down to 100 feet at night just to say I did it. The lowest I ever flew at night in the F-111 was 500 feet, though I flew at 200 feet when flying under visual flight rules (VFR) conditions all the time.
Anyway, run in low then turn off when inside around 20 miles or so. This gave us our best resolution on the radar and I think the numbers were something like we could see objects as separate if they were a bit less than 10 feet apart. So, if you have two cars five feet apart they show up as one blob. If they were 15 feet apart they would show up as two blobs.
If the radar did not have enough grazing angle to see the target the WSO would direct us to climb. Once he had the picture we would turn target direct and drop back down to our attack altitude that was dictated by the bomb fuse combination that we were carrying.

Putting the Strike Eagle’s arsenal to work during Desert Storm
The standard for the start of the war was the MK-20 Rockeye cluster bomb which if I remember right had a timer fuse on it. A certain time after being dropped the MK-339 timer fuse would fire. The bomb would spin after release from the fins popping out at the back at an angle. When the fuse fired, the case split open, and the bomblets inside spread out due to centripetal acceleration. If you released too high the pattern was wider and if too low the pattern was narrower.
The bombs were dual purpose. If they hit something hard they would form a shape charge of plasma and burn through armor. If they hit something soft they would go off like a hand grenade and generate shrapnel. I loved Rockeye, great stuff, carried it the first few nights of the war and took out several Scud missiles with it.
By the end of the war we were primarily dropping CBU-87s, bigger at 1,000lbs than the 750lb Rockeye. That was nice because it had more bomblets. It was not nice because we could not carry 12 of them on the CFT’s, 6 per side, and carry wing-tanks as well, the top three bombs on each side were too close to the tanks. Thus we either carried less, six to be exact, or we carried less gas, a center line tank instead of up to 3 tanks, 2 on the wing plus the centerline tank.
The CBU-87 had a radar proximity fuse. As a result if I released it on or above the minimum altitude I got the exact same dispersion of the bomblets. This came into play after the second night of the war when we started dropping from what we used to consider the stratosphere, the mid-teens to high twenties (thousands of feet). We could still cover a huge area on the desert with a carpet of white fire. These were the best dumb bombs we used for the vast majority of targets we attacked during Desert Storm.
Laser Guided Bombs (LGBs) are visual flight rules only weapons. The laser is attenuated by visible moisture. Sometime you could use a ground laser beneath a cloud deck, the aircraft could drop the bomb ballistically and the guy on the ground would guide it in by illuminating the target with his laser.
At the start of the war we had Paveway II LGBs in 500lb (GBU-12) and 2000lb (GBU-10) configurations. It didn’t matter to the aircrew which he carried as they were identical in employment. We did not start using them until a bit into Desert Storm as we only had nine LANTIRN targeting pods for 48 aircraft. We were up to 24 pods by the end of the war. Because of this, we always used them from medium altitude in one of two ways.
If the aircraft was lasing (painting a target with a laser) for itself, it would drop the bomb and immediately crank off about 45 to 60 degrees while continuing to lase the target. I think usually we would use a “delay-lase” tactic though, where we would not turn the laser back on after release until 15 seconds or so to impact. This was to keep the bomb falling ballistically. If you had the laser on full time then as soon as the laser was seen by the seeker it would point straight at the target and cause the bomb to come in at a slightly shallower angle than it would with a delayed laser operation. Steeper meant faster and more energy to maneuver to steer to the laser spot. I have actually seen slow motion footage of bombs hitting short with the bomb at a very nose-high angle of attack as the seeker struggled to keep on target and the bomb got too slow.
By cranking sideways the laser spot would remain on the same side of the target as the bomb, usually. Even when you are lasing the target at almost 90 degrees you would usually have enough laser “splattering” for the bomb to see it. Round oil storage tanks could be tough though. Also, you could end up lasing the side of a building the bomb couldn’t see so it took a bit of artistry to know the right run-in angle and crank-off angle.
The other advantage of cranking-off was avoiding the very disorienting roll of the seeker head as it passes through the vertical. Not only that, but since the LANTIRN targeting pod had the seeker head on the front of the pod’s body, the ability to see to the rear was extremely limited. I have seen a lot of targeting pod video from the war and several times you can see where the laser stops prior to bomb impact due to this. With good crew coordination the pilot could quickly turn back toward the target and roll back out allowing the pod’s laser to stay on target.
Another tactic we used was buddy lasing. In this case the poor wingman (always me as I was a wingman the entire war) who had no targeting pod would drop the bomb ballistically so that his flight lead could have all the fun and be the hero in taking the target out. I kind of felt like the sparring partner for the heavyweight fighter. I did a lot of work with little satisfaction. I know, yes I would like some crackers and cheese to go with my whine.
The flight lead would fly several miles behind the wingman and be able to fly straight towards the target the entire time. This actually gives the bomb the absolute best laser spot as it is more in line with the flight path of the bomb the entire time.
So how big is the laser spot? We had some footage taken out at the Utah test range that actually filmed our LANTIRN targeting laser on the target as we dropped bombs. If I remember right it was a 2 story target building. The laser spot covered most of the entire building when the bombs hit! We were several miles away and it showed how even lasers diverge over distance. The seeker on the bomb tracks the center of the spot so even though it was a big spot we still got good guidance with it.
We also carried the standard MK-82 500lb bombs and another favorite of mine, the MK-84 2,000 pounder. I had one mission against a cloverleaf in the desert of Kuwait with five 2,000lb bombs. We could see the shock-wave as they blew up, even on the darkest night.
We own the night
We used the FLIR (forward-looking Infrared) in the LANTIRN Navigation pod to fly formation at night. Thus in a two ship or more we would fly a train with each wingman being two to four miles behind the aircraft in front. This allowed the radars to be in scan mode rather than remaining locked on to the aircraft in front of it.
I think most flight leads preferred to fly in black-hot on their HUD. I preferred white hot as it was easier to see the aircraft as a white dot than a black dot for me. Our leads tended to criticize us but most of us just shrugged and continued to do what we wanted to as it was our choice and we were the ones who would be embarrassed if we didn’t stay in position. Remember the wingman’s creed – “two, joker, bingo, mayday, and Lead you’re on Fire.” Other than that shut up and color. Be in position and do what you’re trained to do. That way the formation is strong. A weak wingman is worthless.
At that time we had no data-link. Big weakness. All targets passed to the Strike Eagle after takeoff were done verbally. We worked with E-8 JSTARS a lot. They had a SAR radar like ours but theirs could take detailed pictures from much greater ranges. They would then try to talk us onto targets.
They would give us the coordinates, oh yeah also no GPS in the F-15E back then, so coordinates could be up to a half mile or more off. They would then verbally describe the targets they were seeing. “A group of six tanks in a crescent moon oriented towards the northwest.” Sadly many times we would just find some returns near the coordinates they gave and drop our bombs on them.
This was really a problem when we were buddy lasing. Making sure we were on the same target took a lot of time. Of the few buddy lase missions I flew I would usually bring back several of the LGBs. We just ran out of gas before lead dropped all of his and then started to talk us onto a target to drop ours.
I don’t remember if the original LANTIRN targeting pod had the ability to see another laser. This is a huge benefit now. The A-10 had this way back when it first flew with the Pave Penny system. Another aircraft or a ground controller could put a laser out on a target and a pilot would get an indication on his HUD showing where the laser-spot is and thus would be able to find the target immediately. This didn’t matter much for us during Desert Storm as I don’t think we flew with more than one targeting pod in a formation for the entire war.

Modernized Saudi F-15S.
The Strike Eagle ages beautifully
Starting in 1996 Saudi Arabia bought their version of the F-15E, the F-15S. It was downgraded slightly from the USAF’s version. I think originally they weren’t going to get the weapons stations on the CFTs and were going to use BRUs (bomb racks) and MERs (multiple ejector racks) on the wing. They have the weapons stations on the CFTs now, although I just do not know if they had them originally. I will talk though about the F-15S today – the F-15 I wish I would have had 25 years ago.
GPS. Enough said. Hard to imagine living without it.
With GPS comes JDAM (Joint Direct Attack Munition), a dumb bomb made smart with a GPS guidance kit. Wow. That bomb alone is the difference between fighting in the Stone Age and now. All weather accuracy without the need for post target lasing. True launch-and-leave capability.
JDAM offers a much larger effects footprint. One pass, multiple Desired Mean Point of Impacts (DMPIs). I only attacked one target per pass in Desert Storm. Now, with JDAM, I could attack 12 or more targets on one pass. That is a game changer.
USAF

Data-link. I never ever had it but always wanted it. No more “bogey, Manny, 090 for 65 Westbound.” Okay, now I have to know where Manny is, then where am I in relation to Manny. Then take that information I just heard and mentally plot it out and do a fix-to-fix in my head to figure out where he is relative to me. Hmmm. Angle of the something or other squared times… Remember the movie Mars Attacks when the Country Western music is played and the Martians’ heads explode?
Now with the data-link you look down at your display and see exactly where Manny and pretty much everything else is, in color, and relative to your own position. Remember when your teacher told you how nice it was to share? Now you get to share all sorts of stuff, radar, pictures, home movies, the list goes on. Data-link is as much a game changer as GPS.
Targeting Pod mechanized for air-to-air combat. My neighbor back in the 90s at Seymour Johnson was Ziggy Dahl, an instructor WSO in the Chiefs. He used the targeting pod to do air-to-air back before it was optimized to do it. As like most modern fighters of the day we had pulse doppler radar and everyone knows that if you fly perfectly perpendicular to the air-to-air radar locked onto you then you will disappear. Klingon cloaking device on! Our radar could only look to 60 degrees back then, later a bit more, but still way less than 90 degrees. Solution, use the targeting pod which gave you +/- 1 degree accuracy. It worked like a champ but was hard to do.
I understand now that the targeting pod cues to expected position of the target without a ton of work on the WSO’s part (Author’s note: this technology is now being fully integrated also on American ANG F-15Cs equipped with SNIPER targeting pods). Do a hard turn and blank out the targeting pod and it will track where the bogey should be and return to that point in space when you un-blank the pod. Back when I flew it the pod would go stupid if it broke-lock and was blanked out.
AIM-120 AMRAAMs on the wing rails above the fuel tanks. All we had during Desert Storm was the AIM-9L Sidewinder. Great missile but it is a pistol in a rifle fight with the Mig-29s we were facing. To carry the AIM-7 Sparrow we would have to give up bombs on the conformal fuel tanks. In hindsight we would have killed five or more MIGs during the first night if we would have had the flight leads go in with one conformal carrying six MK-20 Rockeyes and one conformal carrying two Aim-7Ms. Oh well.
Now the Strike Eagle always has claws on every flight. Long-range claws. Approach at your own risk claws.
Then and now
Perspective time. Last year I returned to that small government school in central Colorado for delinquent boys and girls called the United States Air Force Academy for my 35th reunion. This was the first reunion I attended. It was a great time with great friends.
35 years prior to my graduation in 1980 was 1945. Jets were rare then with the Lockheed P-80 shooting star designed in 1943 and that was it, and it was not used in WWII. The Germans had a couple, the British had the Glouster Meteor, etc. Still, the piston engine was king. The Spitfire, the Mustang, the B-29 and so on. In 1980, 35 years later, the USAF was flying the A-10, the F-16, the F-15C, and the B-52. Now in 2016, 36 years after 1980, the USAF is flying the A-10, the F-16, the F-15C, and the B-52. Hmmmm.
The difference? GPS and data-link, as well as persistent ISR (Information, Surveillance, Reconnaissance) for the combatant commander and individual warriors. We now have constant ISR on the battlefield. The only ISR we had in Desert Storm was JSTARS and Compass Call, and maybe Rivet Joint, but that was classified way above my head. U-2 and SR-71 too but not for us at the operational level. Today the coverage of the MQ-1 and MQ-9 and other UAVs on the battlefield gives incredible situational awareness available to the average pogue that was not available 25 years ago.
We could destroy every single target hit during the entire Desert Storm with one squadron of F-15Es or F-15Ss today. Precision attacks on multiple targets per aircraft per pass, day, night and in any weather.
Would we? Doubtful. We have more capability today but are hitting far less targets due to the fear of collateral damage – but that is another discussion for another day.
A huge thanks for Richard Crandall for sharing his incredible experiences and perspectives with us. Stay tuned for the second installment where he details his time flying General Dynamics swing-wing bomber, the iconic F-111, at the height of the Cold War.

Basically a bunch of nerdy skinny guys with coke bottle eyeglasses and pocket protectors found that if they had the radar sweep back and forth a couple of times and then analyzed all of the pictures, checked them twice to see if we were naughty or nice, and then took the cube root of the square of the phase of the moon, that they could give us a picture of the ground that looked like it was taken from a satellite. It was incredible. Fences looked like fences. Buildings were square instead of blobs. Radar scope interpretation became much-much easier and bombing accuracy became much better.
To use the Synthetic Aperture Radar we had to move sideways to the target for a couple of sweeps. The greater the angle off the nose the area was we wanted to look at the faster the picture and the more accurate the radar picture was. This totally changed our target area behavior. In the F-111 you flew straight at the target as the WSO used the radar to find it. In the Strike Eagle we would fly at an angle to the target and turn direct only after the WSO found and designated it.
This was not that big of a deal really. We had to maneuver anyway to get minimum safe distance between each striking aircraft so we just integrated the need to map the target into our plan to attack from different directions at different times.
We would run in low. The F-15E could fly TFR down to 100 feet though I only used 200 feet to my eternal regret. Woulda-coulda-shoulda gone down to 100 feet at night just to say I did it. The lowest I ever flew at night in the F-111 was 500 feet, though I flew at 200 feet when flying under visual flight rules (VFR) conditions all the time.
Anyway, run in low then turn off when inside around 20 miles or so. This gave us our best resolution on the radar and I think the numbers were something like we could see objects as separate if they were a bit less than 10 feet apart. So, if you have two cars five feet apart they show up as one blob. If they were 15 feet apart they would show up as two blobs.
If the radar did not have enough grazing angle to see the target the WSO would direct us to climb. Once he had the picture we would turn target direct and drop back down to our attack altitude that was dictated by the bomb fuse combination that we were carrying.

Putting the Strike Eagle’s arsenal to work during Desert Storm
The standard for the start of the war was the MK-20 Rockeye cluster bomb which if I remember right had a timer fuse on it. A certain time after being dropped the MK-339 timer fuse would fire. The bomb would spin after release from the fins popping out at the back at an angle. When the fuse fired, the case split open, and the bomblets inside spread out due to centripetal acceleration. If you released too high the pattern was wider and if too low the pattern was narrower.
The bombs were dual purpose. If they hit something hard they would form a shape charge of plasma and burn through armor. If they hit something soft they would go off like a hand grenade and generate shrapnel. I loved Rockeye, great stuff, carried it the first few nights of the war and took out several Scud missiles with it.
By the end of the war we were primarily dropping CBU-87s, bigger at 1,000lbs than the 750lb Rockeye. That was nice because it had more bomblets. It was not nice because we could not carry 12 of them on the CFT’s, 6 per side, and carry wing-tanks as well, the top three bombs on each side were too close to the tanks. Thus we either carried less, six to be exact, or we carried less gas, a center line tank instead of up to 3 tanks, 2 on the wing plus the centerline tank.
The CBU-87 had a radar proximity fuse. As a result if I released it on or above the minimum altitude I got the exact same dispersion of the bomblets. This came into play after the second night of the war when we started dropping from what we used to consider the stratosphere, the mid-teens to high twenties (thousands of feet). We could still cover a huge area on the desert with a carpet of white fire. These were the best dumb bombs we used for the vast majority of targets we attacked during Desert Storm.
Laser Guided Bombs (LGBs) are visual flight rules only weapons. The laser is attenuated by visible moisture. Sometime you could use a ground laser beneath a cloud deck, the aircraft could drop the bomb ballistically and the guy on the ground would guide it in by illuminating the target with his laser.
At the start of the war we had Paveway II LGBs in 500lb (GBU-12) and 2000lb (GBU-10) configurations. It didn’t matter to the aircrew which he carried as they were identical in employment. We did not start using them until a bit into Desert Storm as we only had nine LANTIRN targeting pods for 48 aircraft. We were up to 24 pods by the end of the war. Because of this, we always used them from medium altitude in one of two ways.
If the aircraft was lasing (painting a target with a laser) for itself, it would drop the bomb and immediately crank off about 45 to 60 degrees while continuing to lase the target. I think usually we would use a “delay-lase” tactic though, where we would not turn the laser back on after release until 15 seconds or so to impact. This was to keep the bomb falling ballistically. If you had the laser on full time then as soon as the laser was seen by the seeker it would point straight at the target and cause the bomb to come in at a slightly shallower angle than it would with a delayed laser operation. Steeper meant faster and more energy to maneuver to steer to the laser spot. I have actually seen slow motion footage of bombs hitting short with the bomb at a very nose-high angle of attack as the seeker struggled to keep on target and the bomb got too slow.
By cranking sideways the laser spot would remain on the same side of the target as the bomb, usually. Even when you are lasing the target at almost 90 degrees you would usually have enough laser “splattering” for the bomb to see it. Round oil storage tanks could be tough though. Also, you could end up lasing the side of a building the bomb couldn’t see so it took a bit of artistry to know the right run-in angle and crank-off angle.
The other advantage of cranking-off was avoiding the very disorienting roll of the seeker head as it passes through the vertical. Not only that, but since the LANTIRN targeting pod had the seeker head on the front of the pod’s body, the ability to see to the rear was extremely limited. I have seen a lot of targeting pod video from the war and several times you can see where the laser stops prior to bomb impact due to this. With good crew coordination the pilot could quickly turn back toward the target and roll back out allowing the pod’s laser to stay on target.
Another tactic we used was buddy lasing. In this case the poor wingman (always me as I was a wingman the entire war) who had no targeting pod would drop the bomb ballistically so that his flight lead could have all the fun and be the hero in taking the target out. I kind of felt like the sparring partner for the heavyweight fighter. I did a lot of work with little satisfaction. I know, yes I would like some crackers and cheese to go with my whine.
The flight lead would fly several miles behind the wingman and be able to fly straight towards the target the entire time. This actually gives the bomb the absolute best laser spot as it is more in line with the flight path of the bomb the entire time.
So how big is the laser spot? We had some footage taken out at the Utah test range that actually filmed our LANTIRN targeting laser on the target as we dropped bombs. If I remember right it was a 2 story target building. The laser spot covered most of the entire building when the bombs hit! We were several miles away and it showed how even lasers diverge over distance. The seeker on the bomb tracks the center of the spot so even though it was a big spot we still got good guidance with it.
We also carried the standard MK-82 500lb bombs and another favorite of mine, the MK-84 2,000 pounder. I had one mission against a cloverleaf in the desert of Kuwait with five 2,000lb bombs. We could see the shock-wave as they blew up, even on the darkest night.
We own the night
We used the FLIR (forward-looking Infrared) in the LANTIRN Navigation pod to fly formation at night. Thus in a two ship or more we would fly a train with each wingman being two to four miles behind the aircraft in front. This allowed the radars to be in scan mode rather than remaining locked on to the aircraft in front of it.
I think most flight leads preferred to fly in black-hot on their HUD. I preferred white hot as it was easier to see the aircraft as a white dot than a black dot for me. Our leads tended to criticize us but most of us just shrugged and continued to do what we wanted to as it was our choice and we were the ones who would be embarrassed if we didn’t stay in position. Remember the wingman’s creed – “two, joker, bingo, mayday, and Lead you’re on Fire.” Other than that shut up and color. Be in position and do what you’re trained to do. That way the formation is strong. A weak wingman is worthless.
At that time we had no data-link. Big weakness. All targets passed to the Strike Eagle after takeoff were done verbally. We worked with E-8 JSTARS a lot. They had a SAR radar like ours but theirs could take detailed pictures from much greater ranges. They would then try to talk us onto targets.
They would give us the coordinates, oh yeah also no GPS in the F-15E back then, so coordinates could be up to a half mile or more off. They would then verbally describe the targets they were seeing. “A group of six tanks in a crescent moon oriented towards the northwest.” Sadly many times we would just find some returns near the coordinates they gave and drop our bombs on them.
This was really a problem when we were buddy lasing. Making sure we were on the same target took a lot of time. Of the few buddy lase missions I flew I would usually bring back several of the LGBs. We just ran out of gas before lead dropped all of his and then started to talk us onto a target to drop ours.
I don’t remember if the original LANTIRN targeting pod had the ability to see another laser. This is a huge benefit now. The A-10 had this way back when it first flew with the Pave Penny system. Another aircraft or a ground controller could put a laser out on a target and a pilot would get an indication on his HUD showing where the laser-spot is and thus would be able to find the target immediately. This didn’t matter much for us during Desert Storm as I don’t think we flew with more than one targeting pod in a formation for the entire war.

Modernized Saudi F-15S.
The Strike Eagle ages beautifully
Starting in 1996 Saudi Arabia bought their version of the F-15E, the F-15S. It was downgraded slightly from the USAF’s version. I think originally they weren’t going to get the weapons stations on the CFTs and were going to use BRUs (bomb racks) and MERs (multiple ejector racks) on the wing. They have the weapons stations on the CFTs now, although I just do not know if they had them originally. I will talk though about the F-15S today – the F-15 I wish I would have had 25 years ago.
GPS. Enough said. Hard to imagine living without it.
With GPS comes JDAM (Joint Direct Attack Munition), a dumb bomb made smart with a GPS guidance kit. Wow. That bomb alone is the difference between fighting in the Stone Age and now. All weather accuracy without the need for post target lasing. True launch-and-leave capability.
JDAM offers a much larger effects footprint. One pass, multiple Desired Mean Point of Impacts (DMPIs). I only attacked one target per pass in Desert Storm. Now, with JDAM, I could attack 12 or more targets on one pass. That is a game changer.
USAF
F-15E's dropping bunker busting BLU-109s with JDAM kits.
Data-link. I never ever had it but always wanted it. No more “bogey, Manny, 090 for 65 Westbound.” Okay, now I have to know where Manny is, then where am I in relation to Manny. Then take that information I just heard and mentally plot it out and do a fix-to-fix in my head to figure out where he is relative to me. Hmmm. Angle of the something or other squared times… Remember the movie Mars Attacks when the Country Western music is played and the Martians’ heads explode?
Now with the data-link you look down at your display and see exactly where Manny and pretty much everything else is, in color, and relative to your own position. Remember when your teacher told you how nice it was to share? Now you get to share all sorts of stuff, radar, pictures, home movies, the list goes on. Data-link is as much a game changer as GPS.
Targeting Pod mechanized for air-to-air combat. My neighbor back in the 90s at Seymour Johnson was Ziggy Dahl, an instructor WSO in the Chiefs. He used the targeting pod to do air-to-air back before it was optimized to do it. As like most modern fighters of the day we had pulse doppler radar and everyone knows that if you fly perfectly perpendicular to the air-to-air radar locked onto you then you will disappear. Klingon cloaking device on! Our radar could only look to 60 degrees back then, later a bit more, but still way less than 90 degrees. Solution, use the targeting pod which gave you +/- 1 degree accuracy. It worked like a champ but was hard to do.
I understand now that the targeting pod cues to expected position of the target without a ton of work on the WSO’s part (Author’s note: this technology is now being fully integrated also on American ANG F-15Cs equipped with SNIPER targeting pods). Do a hard turn and blank out the targeting pod and it will track where the bogey should be and return to that point in space when you un-blank the pod. Back when I flew it the pod would go stupid if it broke-lock and was blanked out.
AIM-120 AMRAAMs on the wing rails above the fuel tanks. All we had during Desert Storm was the AIM-9L Sidewinder. Great missile but it is a pistol in a rifle fight with the Mig-29s we were facing. To carry the AIM-7 Sparrow we would have to give up bombs on the conformal fuel tanks. In hindsight we would have killed five or more MIGs during the first night if we would have had the flight leads go in with one conformal carrying six MK-20 Rockeyes and one conformal carrying two Aim-7Ms. Oh well.
Now the Strike Eagle always has claws on every flight. Long-range claws. Approach at your own risk claws.
Then and now
Perspective time. Last year I returned to that small government school in central Colorado for delinquent boys and girls called the United States Air Force Academy for my 35th reunion. This was the first reunion I attended. It was a great time with great friends.
35 years prior to my graduation in 1980 was 1945. Jets were rare then with the Lockheed P-80 shooting star designed in 1943 and that was it, and it was not used in WWII. The Germans had a couple, the British had the Glouster Meteor, etc. Still, the piston engine was king. The Spitfire, the Mustang, the B-29 and so on. In 1980, 35 years later, the USAF was flying the A-10, the F-16, the F-15C, and the B-52. Now in 2016, 36 years after 1980, the USAF is flying the A-10, the F-16, the F-15C, and the B-52. Hmmmm.
The difference? GPS and data-link, as well as persistent ISR (Information, Surveillance, Reconnaissance) for the combatant commander and individual warriors. We now have constant ISR on the battlefield. The only ISR we had in Desert Storm was JSTARS and Compass Call, and maybe Rivet Joint, but that was classified way above my head. U-2 and SR-71 too but not for us at the operational level. Today the coverage of the MQ-1 and MQ-9 and other UAVs on the battlefield gives incredible situational awareness available to the average pogue that was not available 25 years ago.
We could destroy every single target hit during the entire Desert Storm with one squadron of F-15Es or F-15Ss today. Precision attacks on multiple targets per aircraft per pass, day, night and in any weather.
Would we? Doubtful. We have more capability today but are hitting far less targets due to the fear of collateral damage – but that is another discussion for another day.
A huge thanks for Richard Crandall for sharing his incredible experiences and perspectives with us. Stay tuned for the second installment where he details his time flying General Dynamics swing-wing bomber, the iconic F-111, at the height of the Cold War.

Is there a source for this? I always assumed the interest the RSAF posed was just in passing, not serious intent to buy.

Technically it would have been a much better aircraft, so it would have made sense. Nonetheless no official statement accepts or denies this interest.

Yes, it would have been a much better aircraft but we all know that better technical specs don't always equate to successful armament deals.

There is a reason the F-15SE has not been selected by any one: The expense is not worth the RCS [Radar Cross Section] reduction which if implemented would still not make it an LO [Low Observable] airframe; and that similar tactical benefits (or more) that would accrue from the reduced RCS can be approximated or bettered just by the integration of AESA [Active Electronically Scanned Array] radar, DEWS [Digital Electronic Warfare Suite], and Eagle Eyes IRST [Infra-Red Search & Track] integration. I don't believe the DFBW [Digital Fly By Wire] system and extra hardpoint should have been pursued though.
With the current F-15S being upgraded to F-15SA standard, the myriad virtues of commonality (benefits include logistics and cross-training which become paramount specially after Day Zero of any combat) are extremely critical for any force not just a small- or mid-sized force that lacks its own development and manufacturing base.
F-35 Pilot Interview on how many airframes the USAF can afford and support
All the good bits that could be built into the existing F-15E airframe have been incorporated into the F-15SA except the more advanced APG-82v1 radar and RAM [Radar Absorbent Material] application which were not released. Now that the painful development of DFBW is over with, Israel is half likely to order its own versions of the SA model with the better radar, RAM, and its own avionics. They want something affordable to complement the F-35 and are definitely getting EDA [Excessive Defense Article] F-15s (specially D models) from the US to upgrade to F-15I standard. I don't see them ordering more F-16Is and if they don't take a decision on new F-15 airframes within a couple of years, that opportunity would likely close also.
There is no reason the F110-GE-132 engine cannot be installed into an F-15E. However, there is no performance benefit (only very slightly higher fuel consumption) that would accrue as the -129 is already past pushing the airframe's aerodynamic limits:
With a beefier landing gear, the -132 would allow the F-15 to lift off with full CFTs, three tanks, and 8,000 pounds bomb load (also more AMRAAMs if you have the extra pylon), which the E model cannot. However, this is an unrealistic payload and all the strike versions can already deliver 4,000 pound bomb loads 1,000 nautical miles away. Please keep in mind that every mile that has to be flown through defended airspace is worth anywhere from 5 to 20 nautical miles (taken out) of this figure. This is where the F-35 coupled with AWACS and air-superiority assets excels. It can actually deliver a 4,000 pound bomb load 500 nautical miles from its last air-refueling (on Day Zero when air dominance has not been established) and can actively take out the enemy air defenses [DEAD - Destruction of Enemy Air Defnses] so that legacy aircraft can start to be used.
The newer F-15 radars are reliable and do not suffer from the awful performance and reliability of earlier APG63 versions. Also, the Eagle Eyes IRST is extremely aerodynamically well-integrated and its positioning is actually better for a high-flying machine that excels in high-speed, high-altitude combat (the F-15 can still turn with the F-22 and Typhoon up there if trimmed and well-flown though it won't be able to see the Raptor until it is too late).
For everyone complaining about my copy-and-pasting, all this is my own personal analysis and you are free to flame and down me all you like.
@gambit can correct all my mistakes and erroneous posturings here. I would prefer to listen to what actual experts like him and @Taygibay have to say if they would ever be so inclined.

Sorry!!!
You know you are my "ustad". It was just a silly, private opinion I wanted the advice of fighter pilots on and was too scared to call Bilal 777 on.

The Rafale and Peter Collins
Image: Dassault
I was sad to hear that Peter Collins passed away this Summer. Collins flew Harrier GR3s with the RAF, Sea Harriers in the Falklands on exchange with the Royal Navy Fleet Air Arm, and the VAAC Harrier (which was instrumental in developing the flight control laws for the F-35B). He also flew with the Red Arrows. Flying both the exceptionally demanding Harrier and as a member of one of the world’s best aerobatic teams show him to have been an exceptionally gifted pilot.
Peter later became Flight International’s test pilot. His glowing review of the Rafale was particularly interesting. With his great experience and knowledge of flying fighter aircraft, I was keen to ask his opinion on modern fighters. I was also asked him about the perennial Rafale versus Typhoon question. As he has flown Rafale and has the Typhoon simulator (programmed to represent the latest variant) he was one of the most qualified to discuss this subject. It was last December that I had the chance to bombard him with my schoolboy questions.
In regards to within-visual range combat he noted:
“This is always difficult to call. The Typhoon helmet mounted display, especially in the yet to be ordered Striker 2 version, is superb. I think the Rafale would eat Typhoon below 10,000ft. The Bug (legacy Hornet) is also superb”
Peter was a staunch supporter of the Rafale, and believed many underestimate it.
“My 2009 article for Flight international stands. If I was buying a multi-role aircraft I would buy Rafale but an awful lot of politics, economics, offset deals, military preference and bias comes in the way…I’m not paid by Dassault or Eurofighter. Remember that the Rafale is designed to replace seven French types: Jaguar, Marine F-8 Crusader, Marine Super Etendard, Mirage F1, Mirage F1R, M2000C and the M2000N – which is probably why it is optimised for lower levels. It is recce-, nuclear (ASMP)- , carrier-capable (something Typhoon will never be), it has AESA, is getting Meteor, drops SCALP, Hammer and LGB. It has better low-observable shaping, and will stick with Typhoon below 20,000 feet. It has very good electronic countermeasures in SPECTRA, and has better flight control system characteristics (I’ve flown it). It also has GPS based, and therefore silent, auto terrain following. It also has forward optics for visual identification. It is the best fighter aircraft I have ever flown.”
He was also mindful of the pitfalls of writing about military aircraft “Careful you don’t put your name to something and be seen as a ‘useful idiot’ by an aircraft manufacturer.” Indeed, much of aviation ‘journalism’ is the uncritical copy and pasting of press statements, and this is an important thing to remember."

That is a fine viewpoint overall you gave us, mate!
Yes, there is a limit to add-ons on any airframe. The main reason
is that aerodynamic solutions act & age pretty much as body does.
An aircraft is not designed in a vacuum but according to two sets
of specifications, general and end performance respectively. It is to
fit these that the means of the time are applied.
The result is as an individual : a precise frame and shape with very
specific abilities and compromise : small and agile, big and powerful,
sprinter or long distance runner, etc.
That formula then ages with a positive side : new technologies equating
experience are added causing an increase in body weight : the bad side.
Of course, you can add performance enhancements ( drugs / new engines )
but there is an inherent set of limits which is why both fighters ( whether
boxers or ACs ) and weightlifters have weight classes : strongmen are hulky
beasts because you need a big frame to lift heavier, period.
The cell can be redone, redesigned with modern materials to gain in the
power to weight ratio but that results in a different aerodynamic solution
and usually in a bigger AC [ Check out the Hornet to SuperHornet history ]. Apart
from composites however, titanium and aluminium alloys remain essential
structural materials so that things haven't changed as much as some think.
But those same physical world limits also show in design and we don't make
mach 4 aircrafts because of a thing called structural strength that has to
increase along with forces applied that makes turn radii less pronounced
at higher speeds to avoid crumpling under moment load ( pilots would suffer too ).
The advances in missile performances, not hindered by humans or wings,
also cover such speeds and a MiG-31 wouldn't out-turn a Meteor nowadays
as it could a Phoenix or a Sparrow ( AIM-54 / AIM-7M ) when it first came out.
The F-15 is an incredible fighter which is why it lasted so long and adapted
to the tech gains by getting more variants, the process that saw such ACs
become multi-role. Lesser planes would have remained interceptors. It is
its great aerodynamic solution that let it evolve so but to really go further
than the SA after 40 years, an in-depth redesign is a sine qua non. And we
already know what it would look like : the original F-15's son is the Raptor
and its spiritual child is the Rafale.
Israel is a different case however due to particular advances in jamming to
no other alike. If that can be ported down to fighters, size will be a necessity
which the Strike Eagle alone offers ( as they're unlikely to buy Sukhois ).
The single factor that has stopped the Eagle from becoming silent is the
cost of the F-35 program, not the obsolescence of its formula.
Keep up the good work and good convo, Tay.

General Chuck Yeager had pretty much the same viewpoint as Tay's when he was involved in picking the F-15E for the strike role (over the F-16XL).
So, I guess I have two greats to influence and turn my opinions around so far.
Thanks for the generous reply sir.

What General Yeager found the primary discerning difference between the F-15E and the F-16XL (once the E had been redesigned with Conformal Fuel Tanks [CFTs] to alleviate its range and weapons carriage disadvantage compared to the XL) was that the F-15E had 15 cubic feet of room (excess beyond that required for necessary equipment and radar) to install avionics compared to the F-16XL's 9 cubic feet.
The XL's avionics space had already been expanded beyond the original 2 cubic feet excess area set aside by General Dynamics in the original F-16 (the original limitation designed-in on the insistence of Colonel Boyd principally, who had not wanted the aircraft to grow so much in weight and complexity that it would end up losing its air-superiority edge; also, the interminable and eventually partly-unfulfilled avionics development of the F-111 was heavy on his mind and the sorry state of airborne radar design also preyed on him enough to recommend deleting the radar altogether from the original YF-16 design).
My own thinking was that this avionics space requirement has since been mostly superseded by the digitization and miniaturization of avionics equipment, and I wanted an opinion on how much avionics room is desired in current fighter design, and at what point will it start impacting fighter performance.
Tay has pointed out that what room can be designed-in without significantly affecting structural weight (making room for each pound of avionics normally ends up costing a couple of pounds in eventual aircraft structural gross weight) can be gainfully employed in installing ever higher-powered jammers.
The F-16C Block 50/52+ made room for electronics in the base of its tail but the two-seat D model has a whopping additional 30 cubic feet in its spine and this is where its sting lies. The two-seat model is ideally suited for the Interdiction and Suppression of Enemy Air Defense [SEAD] missions where the extra man in the back can take care of the enemy's defenses and the actual bombing, while the pilot and the escort single-seater take care of flying and air combat.
F-16 Training Mission
Another unsaid question was the amount of Low-Observability [LO] that can be built into a legacy airframe design not expressly designed for radar/infra-red stealth.
Tay has asserted that the F-15SE Silent Eagle would have been better in some aspects of X-Band reflectivity than I presume. Given internal weapons carriage only, Radar Absorbent Material [RAM] application to major exposed reflecting surfaces, and the tail-canting and slight airframe reshaping, maybe he is correct.
My concern is with when external fuel and weapons have to be carried to fulfill any reasonable mission, and in how much the frontal Radar Cross section [RCS] can be reduced through the currently shown intake reshaping and turbine blade treatments:
Allah keep everyone safe
