Arguments of choosing JF-17 Thunder over JAS-39 Gripen

Before Any ones goes any further please read this is not a VS thread but on the contrary, it is to compare the 2 platforms to analise why do people think that the one is better then the other, and we should have gone for this rather then that.

Now many here advocate that Gripen is a better platform and Pakistan should have opted for it, rather then trying to produce their own in thunder. Now for arguments sake, let say that Gripen was not sanctions prone, and we could buy them just like we are producing the thunder. What would you still go with, being a layman while looking at the specs they look kinda similar to me, apart from the fact that Gripen has the experience of Saab behind it. What do you guys think. And again this is not a Vs thread. Please dont make it into one. Thanks.



Sir,

You started a wonderful thread---but sadly---not one post has followed the parameters that you set forth in your post.

Secondly---you set very poor standards for analysis---instead of thinking like a " layman "---you should have stated---all laymen think like millitary strategist and come up with a millitary based analysis of which should be had---the Grippen or the JF 17---all analysis must be based with millitary thinking---political aspects.

What is the political fallout for either getting a Grippen or a JF 17----Mr Khalidali---major weapons systems---all have political aspirations---major weapons systems are not purchased just for the heck of it---.

I hope I am not being disrespectful----.

If you remeber---or others may remember---I stated c year or two ago---JF 17 is a wonderful plane---it will take around----2013---2015 for it to mature---it will take about 5 years for the pilots to start getting in sync with this plane and quite a few TT members including our famed member were ridiculing me kindly---.

The growing pains of the JF 17 are many---and that is not unusual with any new aircraft---all aircraft go through that. Integration is no joke---.

I wish that some of you kids put your thinking caps on and think like men and strategists and don't be jumping up and down with every news release.

if we have chance we should buy if not more than atleast 20 for our airforce wing and keep them in multan so when war comes they will have first fight with IAF jets
 
.
Problem remains that choice between two different aircrafts is not a simple comparison. If one fighter is better than the other on paper, does it mean that no one will buy the inferior plane and only go for the best?

Quality is very subjective and depends a lot on circumstance and operability in a particular environment. Training, availability of spare parts and familiarity with the aircraft as well as skill of the manpower play a major role in evaluating an aircraft for particular country. Ergo question of opting one or the other cannot be decided on paper specification alone.

For example Euro fighter is probably the best non stealth aircraft in the world today. One way would be as India is doing. Ask for international tenders and evaluate each aircraft on pure merit. Only disadvantage of this method is that process takes too long and requirements may change while the evaluation process is still going on. However Pakistan cannot adopt this procedure because:

1.Pakistan doesn’t have hundreds of billions in FE reserve fund.
2. Even if Pakistan had the money, Typhoon may not offered to Pakistan due to political reasons.

Even if the all the above conditions were met. PAF may still go F-16 block 60 instead of Typhoon because F-16 infra structure is already place and the aircraft can be inducted right away. This illustrates that choice of one aircraft over the other is always subjective.

Finally, no country has infinite resources and numerical advantage makes hell of a lot of difference. Russian T-34 was nowhere as good as the German Tiger, however T-34 prevailed. Therefore it is impossible to make a judgement about the choice of an aircraft without cost considerations.

hi,

That is an excellent post by Niaz----.

But here is something to ponder----the scenario and the gameplan for the upcoming combat has changed.

The elctronic markmanship, high quality missiles and rounds and special armour has completely changed the face of the current battlefield---if you can strike at your enemy at 3000---4000 yds without any fear of the enemy striking back---it is a turkey shoot----even within 2000 to 2500 yds when the enemy round doesnot do major damage to your equipment---that is an aphrodisiac in itself---. So, you can shoot and scoot---come back and do somemore damage and keep away from the enemy effective range.

The game has changed----those with a longer reach will employ different tactics in this day and age---and they will keep doing that from longer distances and break the opponents back before getting within reach of the opponent.

These tactics are already being shown in different wars and millitary excercizes---and the emphasis in training to fight different, is at the top of the list---.


Secondly---in our scenario---pak / india---we really have to thank india for giving us the breathing room----for it takes so long for them to get what they want and then still they change their minds----.

Which makes me awonder at times----that there are people on both sides---pak and india---who are just deliberately taking too much time in making major weapons purchase---it is just a fleeting thought.
 
.
MK..we generally wait to let India make the purchase..then decide our response.
An exception being the F-16 Peace Gate I..
Where the Indians were spurred on by our purchase to buy the M2K's.

Aoa,
After watching JAS 39 & JFT video it seemed as if same Pilot flying these aircrafts.................:pakistan:
on the other hand i think Both JAS and JFTs are kinda similar aircrafts as far as abilities and look is concerned........

Nevertheless F-16 & J-10 looks awesome compare to all the aircrafts in world.

The Gripen is classified as a High Tech Fighter. What about the JF-17 does it come in the category of a high tech fighter or is it a medium tech fighter?
 
.
Silent hAWK

High tech fighters costs Start at $50m each minimum and rise to over $100m

Thunder costs $12-15m each.

The high tech fighters incorprate very expensive technlogy thus making them very expensive

eg.

TVC control engines
Pesa or Aesa Radars
in some cases twin engines
Highly advanced sensor fusion technology
Wide range of weapons
Very low RCS
Composite technology in build structure
Canards

Not one of the above appears on the Thunder

Thats why its a very cheap plane.

" this does not mean its not a good plane"

Because it is cheap to buy PAF can acquire hundreds if they wish for a large air force

. In order to improve the aircraft's performance, study on diverterless supersonic intake has been in progress since 1999. Bump intake design on JF- 17 took almost two years with a number of intake models subjected to high and low speed wind tunnel tests. Analysis show that at high speeds, the bump works with forward-swept inlet cowls to give high performance, high total pressure recovery, low integrated distortion, and, good engine/intake matching. It redirects unwanted boundary layer airflow away from the inlets, essentially doing the job of heavier, more com­plex, and more costly approaches being used for because intake is one of the three major forward scatters of an aircraft (30%-35% contribution to aircraft forward Radar Cross Section (RCS)). In order to fully exploit the potential of the aircraft fly-by-wire system and improve the aircraft per­formance, JF-17 design has a wing fore body strike which is about 9% of the Wing area. This has resulted in better matching of the aerodynamic focus with the Center of Gravity (CG) and better harmonization of the air-to-air and air-to-ground CG vari­ations by taking advantage of the pitch digital fly-by-wire Flight Control Systems (FCS). This has improved not only the controllability but has also enhanced the performance through reduction of the supersonic drag. The salient features of "Thunder or Xia Long" enable it to outfit many competitors in the world.

An elec­tro-optical self-protection suite with Missile Approach Warning system (MAWS) enhances its survivability under combat situations. Tactical datalink, with Track-While-Scan (TWS) and Dual Target Track (DTT) modes of the radar provide the pilot, an excellent Situation Awareness (SA) in all conditions. An integrated IFF interrogator along with colored displays provides easy cues for criti­cal decision-making.

JF-17's air combat capability is aug­mented by helmet-mounted display and all-aspect missiles affording high off-boresight launches. With its embedded data link and secure radios, the aircraft is expected to remain viable in future hostile bat­tles, and would prove to be an effec­tive low-cost high performance air defence fighter. It provides an affordable and efficient air-to-air mission capability. On the other hand, due to its advanced aerody­namic design, weapons carriage capability and avionics suite, it can strike the enemy, where it hurts him most in an offensive counter-air campaign. JF-17 thus would not only be lethal but will also be highly survivable.

Its fire and forget capability reduces time on tar­get and thus ensures better surviv­ability. With the integration of AEW&C, JF-17 will have excellent SA even in enemy area to make crit­ical engagement and exit decisions. Furthermore, under hostile conditions, automated self-protection sys­tem of the aircraft affords high sur­vivability rate.

Large Radius Of Action (ROA) of Thunder and its weapon system capability make it an excellent light surface attack aircraft. Ring Laser Gyro (RLG) based Inertial Navigation System (INS) with embedded Global Positioning System (GPS) provides the capability of precision navigation over the entire ROA

It can carry multitude of external stores including conven­tional general purpose bombs, clus­ter bomb units, anti-runway bombs, anti-ship missiles and precision guided weapons that exist today. JF-­17 provides employment flexibility to suit the tactical conditions. JF-17's payload options make it airfield, pre­cision or maritime strike capable. It can be employed even for interdic­tion, armed reconnaissance, battle­field interdiction and close support roles.

It is designed to ensure effective MMI in all types of missions. Its efficient HOTAS controls and col­ored Smart Multi-Function Displays (SMFDs) provide ease of comprehension and control. The aircraft has a wide 24 degree Field Of View (FOV), Smart Head-Up-Display (SHOD) and Helmet-Mounted Display (HMD) provide the requisite menu based controls and displays to the pilot. The symbologies are designed to ensure high SA of the pilot both in air-to-air and surface attack missions. Its Identification Friend or Foe (IFF) interrogator for both air-to-air and air-to-surface applications is available to avoid fratricide in hostile conditions. This advanced MMI concept affords com­puter-controlled capability diagnosis and failure monitoring system to reduce the pilot's work-load. Therefore, the performance index of JF-17 is much higher than that of a second or third generation aircraft, both in air-to-air and air-to-surface scenarios. It would therefore not only meet the objectives for which it is being developed but would also truly prove to be a "Giant Leap" for our progressing aviation industry, thus paving the way for future growth in related fields.

Which makes me awonder at times----that there are people on both sides---pak and india---who are just deliberately taking too much time in making major weapons purchase---it is just a fleeting thought.

Gripen was officially declined by Swedish govt. upon US pressure, while PAF wanted to have it.
After, that official decline, PAF went into JFT collaboration.

Greetings from Sweden, I read your excellent thread and thought I could contribute some facts about Gripen. It’s from me, Robban, and various others.

First Supersonic flight. From 2001..


"There was one interesting problem,” Colonel Eldh concludes with a smile. “Gripen is supersonic at all altitudes and can cruise supersonically with an external load including fuel tank, four AMRAAM and two sidewinder missiles without the need to engage the afterburner..

In the early days of operations, we found some pilots inadvertently flying supersonic over populated areas. The problem was one of habit, as these pilots had their throttle settings as high as on the older-generation fighters that Gripen replaced.

It is fair to say there were a few startled people on the ground, as their day-to-day work, or perhaps sleep, was disturbed by unexpected sonic booms! It was, of course, a simple task to solve the problem – the throttles were re-set and everyone was happy.”

Did you notice that we didn’t call it ‘supercruise’ at that time? The idea didn’t exist actually. And it was Gripens excellent air-frame that allowed it, with the technicians and constructors making it possible from the beginning by using a superior design. And NG is no different. We made this aircraft through ‘modular thinking’, building with easy upgrading in mind, from the beginning. That was, and is, a standing specification for all our aircrafts. We need to be able to change in record time, and we need them to be just as sturdy as the Russian. After all, we created the concept from where our eastern neighbours might want to take a ‘stroll’ visiting us.

Some more general Gripen info, not NG specific.

A hot engine change can be made in 45 minutes by a team of three. 10 maintenance hours per flight hour, includes all depot level maintenance. Twice as reliable as its competitors. Twice as easy to repair. Enough ground equipment to support four Gripens can be carried by a single C-130 Hercules. The Gripen can be refuled and rearmed in less than 10 minutes. An airborn time of 60 seconds is possible when on high alert with the APU running, all systems fully avaliable 10 seconds after take off. The F-16 needs 3-4 minutes, and its INS and radar will not be fully avaliable. Gripen mean time between failures(MTBF) is proven to be 7.6 hours. During Red Flag Alaska the seven Gripens that participated logged 346 hours during 225 missions, with 99% availability, USAF best MTBF is 4.1 hours. The Gripen costs less than 2000$ per flight hour. Airframe life is 8000 hours. On a CAP 385km from base, a Gripen can stay on station for two hours carrying 2X AMRAAM, 2X AIM-9 and 2X droptanks. When carrying 3X 1000lbs GBU-16 on a LO-LO-LO strike profile, the Gripen has a mission radius of 648km. With 2X GBU-16's and extra fuel tanks radius increases to 833km. Ferry range is 3500km according to Col Jan Jonsson of the Swedish Air Warfare Center. The Gripen can accelerate from M 0,5 to M 1,1 in 30 seconds. The Gripen can sustain M 1,1 using dry thrust, while carrying a droptank and AAM's. The Gripen can operate from 800m long and 9m wide roadstrips. Take off and landing distances can be down to 350 meters. We have made simulated hangar landnings with Gripen, without needing to get hooked, successfully. Now, that probably isn’t needed for the Pakistan forces, and it still needs to proven realistically on a factual ship. But I’m confident that it can do it, no problems.

Radar (JAS-39): 20% longer than RDY (M2000-5), and 40% longer than the AN/APG-68 for F-16C/D Block40/42. The detection range for the APG-68(v)9 (Polish F-16) is 90~105 km for RCS 5m2 target. The PS-05 detection range against similar sized target is >120km.

JAS-39A: the effective range for Gripen to detect MIG-29 is 60 km longer than the effective range for MIG-29 to detect Gripen. F-16C/D: the effective range for Falcon to detect MIG-29 is 5 km longer than the effective range for MIG-29 to detect Falcon.

Take into consideration the 0.1m2 (average) RCS of the Gripen(F-16C 1.2m2), its superior manoeuvrability and agility, its TIDLS, and its much superior MMI, SA, EWS39 and much more modern infrastructure, the Polish F-16's would never know what hit them. And this RCS is for an Gripen A version. The C version is even smaller, and the NG smaller yet. According to some USAF sources, the F22 radar signature is that of a small bird, the F-35 that of a smaller chicken, and the Gripen NG with air-air missiles as that of a medium-large bird of pray, such as an Eagle, in terms of IR/Heat, the Gripen and the Rafalé performs very well, and even having smaller signatures than that of the F-22 and F-35.

During Spring Flag 2007 when the Hungarians participated in their first international exercise with their Gripens they flew for the red team, meaning their job was to die. They rarely had AWACS or radar support of any kind and they weren't allowed to use AMRAAM's. Yet they made 10 kills in a day. Including a Typhoon. The Hungarian pilots commented that other aircraft couldn't see them on radar, not even visually, and they had no jammers of their own with them. They got a Fox 2 kill on an F-16 who turned in between the two Gripens but never saw the other guy and it was a perfect shot. The Gripen was designed to take on and beat the Su-27 and future derivatives of its design. It's not a machine that needs to be complemented by a larger more capable fighter (F-15-F-16). It's not a more modern F-16 like so many people seems to think.

During Red Flag the Gripens didn't even need to use their EWS39. They remained undetected anyway. And no disrespect to the Norwegian pilots because I know they're just as well trained as us, but during a combat exercise with the Royal Norwegain Air Force, 3 Swedish Gripens went up against 5 RNAF F-16's. The Result was 5-0, 5-0, 5-1 after having flown 3 rounds. During Loyal Arrow in Sweden, 3 F-15C's from the USAF were intercepted by a Gripen acting as an aggressor. The result was 2 F-15's having been shot down and one managed to escape due to better thrust/weight. One Gripen pilot knocked down five F-16 block 50+ during close air combat in Red Flag Alaska. And the Gripens never lost any aerial encounter, or failed their mission objectives. It was the only fighter that perfomed all planed starts, while others where sitting on the ground waiting for the weather to clear up

F-16 has a higher TWR, but one need to consider drag and wing loading too. The Gripen has much lower drag. And far lower wing loading. It can reach supersonic speeds on dry thrust while carrying a full armament of four AMRAAM's two Sidewinders and an external fuel tank. Even though the Gripen lacks the TWR of the F-16 it can nearly match it in climb rate thanks to low drag. The Gripen has positive lift on all control surfaces at all times. The F-16 needs to kill lift in order to turn by forcing the tail down. The Gripen just adds lift in front of the CG with the canards and the aircraft turns by itself. The canards then stabilize the turn rate, creating minimal drag. The IRIS-T is now being integrated for the Gripen. And with its modern infrastructure it can make much better use of it than the F-16. The Gripens ITR is much better than the F-16's and will therefore get its weapons on the F-16 first. The Mirage 2000 for example wins 9 times out of 10 against the F-16 in WVR, and nearly always kills the F-16 during the first turn. This is thanks to its higher ITR. And the Gripen has a higher ITR than the Mirage 2000.

Gripen is pretty much as agile it can get. G onset rate at least 6 G/s (1-9 G in 1.2 s), the Gripen platform is designed with tactics in mind. Gripen fight not only with missiles and bullets but with information, superior situation awareness is the key in modern warfare..

Gripens flight computer is outstanding, and can make some worldclass calculations. Gripens Fedec are highly impressive, it even has a backup mechanical calculation system. something only a handful of companies can manage. The air craft also incorporate a very low radar profile making it hard to find. And it has a superior data link. And in real tests against other aircrafts the radar has been found very hard to jam by other systems, meaning that it will work in practice, not only in theory. And those country's using it have found it working in all weathers.

The radar is capable of detecting, locating, identifying and automatically tracking multiple targets in the upper and lower spheres, on the ground and sea or in the air, in all weather conditions. It can guide four air to air missiles (AMRAAM, MBDA Meteor) simultaneously at four different targets.

The Czech Air Force had this to say after testing the first generation Gripen 2005.

"Sweden required hard discretion related to ALL Gripen abilities information, but rumors say Gripen pilots used to call fox 3 (AMRAAM engagement) farther away than viper guys. When reporters asked guys from AFB Caslav to compare our new birds with another, they answered our fighters (model C block2) are the best HW currently available on the word market."

And also

"Since 1 May we have flown over 570 missions in total [figures as of mid-October] and since 1 July when were went operational on the QRA mission we have flown over 300 missions. We are very busy and we’re flying every day. Every aircraft flies at least twice, each day. We have eight pilots at the moment and sometimes we have all eight flying – and it’s not unusual to have all 12 aircraft operational and available on the line. We have never lost a single operational mission due to a technical snag with the aircraft and every single QRA mission has gone ahead as planned."

"The Gripen has seven external hardpoints for carrying payloads: one at each wingtip, two under each wing and one on the fuselage centreline. The air-to-air missiles include MBDA (formerly Matra BAe Dynamics) MICA, Raytheon AIM-120B AMRAAM and Lockheed Martin / Raytheon Sidewinder AIM-9L (Swedish Air Force Designation RB74).

Sidewinder, mounted on the wingtips, is an all-aspect attack, short-range missile for enhanced dogfight capability. Air-to-surface missiles include the radar-guided Saab RBS15F anti-ship missile and Raytheon Maverick missile. Later versions of the aircraft for Sweden will be armed with the short-range Diehl BGT Defence IRIS-T air-to-air missile and the MBDA Meteor beyond visual range (BVR) air-to-air missile. Deliveries of IRIS-T began in December 2005. Meteor is due to enter service in 2010. The Saab Bofors / MBDA Taurus KEPD 350 long-range stand-off missile, with a range of 350km, has been successfully flight tested on the Gripen. In May 2008, South Africa placed an order for the IRIS-T air-to-air missile to equip its Gripen fleet until the indigenous Denel A Darter missile enters service.

The internally mounted 27mm Mauser high-energy gun can operate in an automatic radar-guided aiming mode. (The 27mm Mauser BK 27 revolver cannon was designed specifically for the Panavia Tornado strike fighter, although it is also used in Germany's version of the Alpha Jet, in the SAAB Gripen, and has been chosen for the Eurofighter Typhoon and the JSF. A four-barrel naval CIWS mount was developed but not used; a simpler remote-control single-barrel mounting is achieving more success.

The latest round is the 30x150B used in the GIAT 30M791, which has been selected for the new Dassault Rafale. Capable of 2,500 rpm, it holds the record as the joint fastest-firing revolver cannon. The rim, belt and head dimensions are different from those of the original 30x113B DEFA case.) The stand-off dispenser is the DWF39 from EADS (formerly DaimlerChrysler Aerospace) and Bofors. The Bofors ARAK 70 rocket pod is cleared for carriage on the Gripen. "


The NG radar specs. Those may have changed slightly, but if so, to the better :)

“Ericsson’s future airborne radar is Not Only a Radar, NORA (for the NG), but also a complete electronic warfare system including jamming and data communication. The new radar will use an Active Electronically Scanned Array, AESA, built up with approximately 1000 individual transmit/receive modules. The antenna, mounted on a single-axis platform, will give well over 200? coverage in azimuth. NORA will offer superior performance by virtue of a number of core capabilities at Ericsson – beam agility, beam widening, multi-channel processing, target-specific waveforms and low radar cross-section.....

It's planned to scan +-60 deg electronically and 60 deg mechanically in azimut, permitting scanning over a 240 deg arc and electronically +-60 deg up and downwards. ...

Fully programmable signal and data processors enable the radar to handle these air defence, attack and reconnaissance missions. This also gives the radar a very high growth potential to meet future requirements. The radars flexible waveforms make it possible to avoid ambiguities and allow performance characteristics to be optimized for all operating modes. The radar also matches the data link requirements for advanced medium range missiles...Ericsson has started development work for upgrading the PS05/A multimode radar. Some of the up-grades have been possible to incorporate, since new, faster and more powerful processors and components have become available on the market. An essential part of these upgrades is a new data processor who will replace the D80 processor in the Systems Computer in Swedish Air Force Gripens. It is a Modular Airborne Computer System (MACS) with higher capacity. A significant upgrade of the signal processor is also included which will dramatically enhance functions in both air-to-air and air-to-ground missions....

Ericsson AESA (Active Electronically Scanned Array) is a new airborne radar project currently in development at Ericsson Microwave Systems. The AESA technology will improve the radars overall performance drastically, especially its target detection and tracking capability. Beam direction can be changed instantaneously, detection range will be considerably increased, and jamming suppression further improved. The AESA radar will feature multibeam capability with all beams individually and simultaneously controlled. It can also operate simultaneously as a fire control and obstacle warning radar, and be used both in intercept and ground attack missions. The multibeam concept also allows for radar operation, data linking, radar warning and jamming simultaneously. As a consequence of the very large number of transmitter and receiver modules, the radar will have a high system availability through graceful degradation...."

Gripen will, due to size only, give approximate 25% of the radar reflection of a F35 JSF. Our ASEA radar have the ability to 'see' stealthed aircrafts due to the 'electromagnetic holes' they will create in the air flying under stealth. We don't need to 'burn through' to do that, it will be 'passive mode', defining their position. The Lockheed Martins JSF.still weights around 2000kg to much, and they will have significant trouble reducing that weight. And when the aircraft is taxing on the ground it is near a 'meltdown' due to its heat conditions.

Our new Gripen will see a F35 JSF coming at least as fast as it will be able to see a Gripen, and that is in good time before any need to shoot. We choose away any increased 'stealth', due to that it generally cost a aircraft its flight performance, creates a small weapon load, combined with a higher fuel consumption. And if it comes to a dogfight? Which plane would you prefer..

Also, according to two reports, one from RAND and the other from Australia the stealth is somewhat exaggerated.. JSF won't, according to those, be able to keep its stealth with a heavy outer weapon load, which was a Norwegian demand. Doing so the F35 JSF will lose its 'signature adaption' as well as its 'claimed' better maneuverability than a Gripen.

Then we come to the Digital Link. Ever heard about the Internet? And why it was built the way they did it. In case of a nuclear war my friends. They made the Internet ‘peer to peer’ so that with only a few nodes left they still would be able to communicate. We started planning for this kind of airborn link in the fifties. Draken was our first aircraft using it, decades before anyone else. We have a long, long experience of developing and using this system. Don’t mix it with any other Digital link system. And don’t believe that because the newest generation of aircrafts are trying to incorporate it they have our experience. We are still the world leaders on peer to peer digital links, and that’s nothing but the truth.

When we, more or less, ‘joined NATO’ we had to downgrade our system as they used an inferior system without peer to peer, namely LINK 16. And that one I still find hard to forgive our military geniuses, that they so much craved to play with the big boys that they choose to weaken our defence capability (TARAS). It Sux, bigtime. But we still have our link, adapting it to NATO. So we will use both. Ours because it will work, without AWACS, we can bind it to any other vehicles aircrafts etc still existing surviving in the warzone, lending their radar images while coming ‘silent’ without radar ourselves. Can you see what that that makes possible?

Also we should be able to connect several individual radars to get a really ‘wide picture’ if needed, although this is my own guess, as well as we might be able too use those radars to ‘magnify’ the reception. But those two is what I think, so, if we can you won’t see any papers on that. But it’s quite possible; after all, we’ve had forty years of ongoing development. The second demands a lot of computer-power in ‘real time’ situations though? So.. A maybe perhaps :), I would definitely have tried though as that would create, using the combined radars, a ‘super radar’ accessible to all pilots, and ground bases/vehicles too.

The Chinese do not have this… the Americans do neither… The Russians? Nope, not as I know. But all are aiming for it, but, you got to remember that we have had it working (peer to peer) forty years before them. The first Drakens with datalink capability were J35B's with the Stril 60 system, delivered in 1964. A centralised system is not the same, so please don’t argue about this. At least read up on why Internet is thought to survive a nuclear war and still be able to connect before you do.

Americans had the MA-1 fire control system which included datalink. F-101B's fitted with a datalink system that were operational by 1962. Called NORAD SAGE. But the F-101B had only a passive datalink. The pilot followed SAGE steering commands transmitted by the datalink to his displays which made it no more than a centralized digital flight-commander. You need to see the difference between those concepts to understand what I’m talking about, and that one you will know best in a real fight. But you won’t, as you won’t know what hit you. With our system there is very little warning. The first warning will be when you notice the missile homing in on you, and by then it will be far too late.

TIDLS (datalink)

”One Gripen can provide radar sensing for four of its colleagues, allowing a single fighter to track a target, while the others use the data for a stealthy attack. TIDLS also permits multiple fighters to quickly and accurately lock onto a target's track through triangulation from several radars; or allows one fighter to jam a target while another tracks it; or allows multiple fighters to use different radar frequencies collaboratively to "burn through" jamming transmissions. TIDLS also gives the Gripen transparent access to the SAAB-Ericsson 340B Erieye "mini-AWACs" aircraft, as well as the overall ground command and control system. This system provides Sweden with an impressive defensive capability at a cost that, though still high, is less than that of comparable systems elsewhere.

TIDLS can connect up to four aircraft in a full-time two-way link. It has a range of 500 km and is highly resistant to jamming; almost the only way to jam the system is to position a jammer aircraft directly between the two communicating Gripens. Its basic modes include the ability to display the position, bearing, and speed of all four aircraft in a formation, including basic status information such as fuel and weapons state. The TIDLS is fundamentally different from broadcast-style links like Link 16. It serves fewer users but links them more closely together, exchanging much more data, and operating much closer to real time.

TIDLS information, along with radar, EW, and mapping data, appears on the central MFD. The display reflects complete sensor fusion: a target that is being tracked by multiple sources is one target on the screen. Detailed symbols distinguish between friendlies, hostiles, and unidentified targets and show who has targeted whom.

Today, Sweden is the only country that is flying with a link of this kind.

The Flygvapnet has already proven some of the tactical advantages of the link, including the ability to spread the formation over a much wider area. Visual contact between the fighters is no longer necessary, because the datalink shows the position of each aircraft. Leader and wingman roles are different: the pilot in the best position makes the attack, and the fact that he has targeted the enemy is immediately communicated to the three other aircraft.

A basic use of the datalink is "silent attack." An adversary may be aware that he is being tracked by a fighter radar that is outside missile range. He may not be aware that another, closer fighter is receiving that tracking data and is preparing for a missile launch without using its own radar. After launch, the shooter can break and escape, while the other fighter continues to pass tracking data to the missile. In tests, Gripen pilots have learned that this makes it possible to delay using the AMRAAM's active seeker until it is too late for the target to respond.

But the use of the link goes beyond this, towards what the Swedish Air Force calls "samverkan," or close-cooperation. One example is the use of the Ericsson PS-05/A radar with TIDLS. An Ericsson paper compares its application, with identical sensors and precise knowledge of the location of both platforms, to human twins: "Communication is possible without explaining everything."

"Radar-samverkan," the Ericsson paper suggests, equips the formation with a super-radar of extraordinary capabilities. The PS-05/A can operate in passive mode, as a sensitive receiver with high directional accuracy (due to its large antenna). Two PS-05/As can exchange information by datalink and locate the target by triangulation. The target's signals will often identify it as well.

The datalink results in better tracking. Usually, three plots (echoes) are needed to track a target in track-while-scan mode. The datalink allows the radars to share plots, not just tracks, so even if none of the aircraft in a formation gets enough plots on its own to track the target, they may do so collectively.

Each radar plot includes Doppler velocity, which provides the individual aircraft with range-rate data. However, this data on its own does not yield the velocity of the target. Using the TIDLS, two fighters can take simultaneous range-rate readings and thereby determine the target's track instantly, reducing the need for radar transmission.

In ECM applications, one fighter can search, while the wingman simultaneously focuses jamming on the same target, using the radar. This makes it very difficult for the target to intercept or jam the radar that is tracking him. Another anti-jamming technique is for all four radars to illuminate the same target simultaneously at different frequencies.'”

Our Swedish Data-link updates every second (or faster:), as compared to Link16 (every twelfth second) This makes it possible for us to fly 'radar silent' and even shoot its missiles from it without any own radar. And the data-link is able to steer you in, in every detail (close control) through its data commands. Which means that Gripen will be very operational even with its radio totally jammed. The NATO variant Link16 can, if I'm correct, open up to four(?) 'timeslots/channels' and if you place them correctly in time, give you a update every third second. (But we can also do that kind of stuff and as our systems each update every second by themselves (or faster:) you might wonder how much info we would be able to transmit that 'NATO' way opening new 'timeslots'. Not that I know of course, just guessing here:)

Our system have the possibility to use AWACS, and satellites, and 'peer2peer'. It seems to me that Link16 first handedly is a 'centralized' system, now also trying to in cooperate some of the Swedish 'ideas'. As for what is best in a battle situation? I prefer the one with the most options myself, and that's not Link16. And it's not only Gripen using our system, it's used in all types of military vehicles, that's why it is so redundant. And that's why we still will have a 3-D sphere of information, even when all AWACS is down. We use all available radar, and their data links too. But remember, ours system is 'peer to peer', just like the Internet, built for durability.

“Link 16 (also known as TADIL J in the US) has been designed to optimize the use of the MIDS/JTIDS architecture. MIDS is a major U.S.-led international programme in which Link 16 compatible data communications terminals are being developed. Link 16 is defined as the designation for Joint Tactical Information Data System (JTIDS) waveform and protocol compatible radios that transmit and receive data messages in the TADIL-J message catalog. Gripen and Saab 340 with Erieye.

Link 16 has been developed to meet the information exchange requirements of all tactical units, supporting the exchange of surveillance data, EW data, mission tasking, weapons assignments and control data. Link 16 is the NATO-standard tactical datalink that is being adopted by more and more users, on more and more platforms, to support coalition operations. In addition to the Swedish data link, Link 16 is now an option in Gripens onboard datalink capabilities. This further enhances Gripen’s interoperability and gives users an even wider choice of networked systems to meet their national and international needs.”

Well, in a way, maybe, but for a prise. We lost some sweet capabilities to that adaption, but hey, look at the bright side, we gained some weight :)

“In BVR combat, where information and situational awareness are key to success, a datalink system gives the user unrivaled battlespace awareness. The advantages of datalink systems are well recognized elsewhere and include the JTIDS used by US armed forces and Britain's RAF, and NATO's Link 16. However, these other systems are fitted only to a few aircraft and are generally command-driven systems used to guide other aircraft. They do not allow a free flow of information between platforms and are limited in the type of data they can handle. Furthermore, compared to the CDL39 their basic data exchange rates are painfully slow. Types like the Super Hornet and Eurofighter Typhoon will be the first operational aircraft outside Sweden to have datalink capability that comes anywhere matching that of the Gripen.

The CDL39 is fully integrated with Sweden's new tactical Radio System(TARAS) - a secure radio network for JAS39 Gripen and JA37D Viggen fighters, S100B Argus AEW&C platforms, S102B Korpen SIGINT aircraft and ground-based Stridslednings Central, Command and Control Center (StriC) units. The FMV is currently working to make CDL39 capable of communicating with JTIDS for international Gripen operations. Up to four aircraft can be actively transmitting on the datalink at any one time and an infinite number can be receiving(passive).

As its most basic function the CDL39 can transmitt radar/sensor pictures and aircraft/weaponry status data anywhere on the TARAS network. To send data on the link all the pilot has to do is select the appropriate radio channel/which will be preset by the mission planning system) and transmit. extensive testing has shown the system to be unjammable.

The Gripen's datalink offers enormous flexibility. For example, in the air to surface role one aircraft "package" can attack a target, obtain a radar picture of the the target area and realy it to the cockpits of the next wave of attackers. Those aircraft would receive an accurate image of the target area, allowing them to know which targets have already been attacked. Furthermore this information can be relayed back to the StriC for decisions based on the actual situation.

In the air to air role it is possible for one Gripen to transmit its radar picture of an airborn target to the radar screen of another aircraft. The second aircraft can the leave its radar switched off, approach the target and engage it without ever betraying its precense. Weapons launch even can be guided from the first aircrafts radar. Using AEW&C radar, a much larger airpicture can be datalinked to a formation of Gripens, to increase their combat reach.

The Gripen/datalink combination offers formidable capabilities. The airforce has run air defence exercises deplying just six Gripens to defend half the country. Using the CDL39, three pairs of aircraft flying CAP are able to monitor Sweden's entire east coast, from the northern edge of the island of Gotland in the Baltic to Ronneby Air Base and beyond, to the souther tip of the country. Each Gripen pilot can be confident that everybody knows where everyone else is at all times, what they are seeing and what they are doing.

(Edinburgh, April 21, 2010) -- SELEX Galileo's prototype of its Raven ES-05 Active Electronically Scanned Array (AESA) radar, the Raven 1000P, is playing a key role in the Saab Gripen Next Generation flight proving and demonstration programme. The programme has been very successful, demonstrating radar modes in flight as well as showing the effectiveness of the SELEX Galileo and Saab team in integrating the radar into the weapon system and proving real capability in very short timescales.

Both air-to-air and air-to-ground modes have been integrated with great success and the expected performance has been achieved. Particular focus was placed on the air-to-ground capability and Raven 1000P produced excellent medium and high resolution SAR imagery at long ranges. Trials will continue and capability insertion will take place at the appropriate points in the development schedule.

And when it comes to Meteor we already have tested it in flight. “Saab together with FMV Test & Evaluation Department accomplished the campaign very successfully. Saab evaluates and analyzes the data gathered from the test firing together with the supplier,” said Michael Östergren, Project Manager at FMV. With this firing the first of two phases in the Swedish integration is now completed. The first phase was designed to support the development of the missile while the next phase is designed to fully integrate the missile on Gripen. The final integration with Gripen for the Swedish Air Force has recently begun and is expected to be finalized during 2013.”

And no, we might have an 4.5 generation airframe, but the electronic capabilitys, and its ‘peer to peer’ is cutting edge, nobody else there yet, as far as I know. So yep, I think it’s a da*n good aircraft:) Actually the USAF acknowledges it as a fifth generation fighter, due to super cruise capability and semi-stealth features. It has a very low radar signature, and an extremely low IR/heat signal. In a way you could say we got lucky with it, but using good planning luck often seem to come.

The next generation will probably be pilot-less for us, if we can afford them. But we’re pretty good at minimizing costs, and we need an independent defence. There’s nothing worse that to find out that you won’t get the parts because, ah, there is a war on, well, for an example :) So we will probably build that one too, just to make sure that we can greet ‘big brother’ appropriately. Still, some parts of Gripen are not ours, and that’s a cost question too. But we modify them to our specifications and try to build on licence as far as possible. I don’t know that much about the Thunder though. It’s definitely cheaper I have to admit.
