SAN DIEGO (NNS) -- The Navy made aviation history Nov. 3 as an F-35C Lightning II carrier variant Joint Strike Fighter conducted its first arrested landing aboard an aircraft carrier off the coast of San Diego.

Navy test pilot Cmdr. Tony Wilson landed F-35C test aircraft CF-03 at 12:18 p.m. aboard USS Nimitz's (CVN 68) flight deck.

The arrested landing is part of initial at-sea Developmental Testing I (DT-I) for the F-35C, which commenced Nov. 3 and is expected to last two weeks.

"Today is a landmark event in the development of the F-35C," said Wilson, a Navy test pilot with Air Test and Evaluation Squadron (VX) 23. "It is the culmination of many years of hard work by a talented team of thousands. I'm very excited to see America's newest aircraft on the flight deck of her oldest aircraft carrier, the USS Nimitz."

Commander, Naval Air Forces, Vice Adm. David H. Buss, was aboard Nimitz to witness the milestone event.

"What a historic day today is for Naval Aviation. With the first traps of the F-35C Lightning II aboard an aircraft carrier, we begin the integration of the next generation of warfighting capability into our carrier-based air wings," said Buss. "This important milestone is yet another indicator of Naval Aviation's ongoing evolution to meet future threats and remain central to our future Navy and National Defense Strategy."

DT-I is the first of three at-sea test phases planned for the F-35C. During DT-I, the test team from the F-35 Lightning II Pax River Integrated Test Force (ITF) has scheduled two F-35C test aircraft from Naval Air Station Patuxent River in Patuxent River, Maryland to perform a variety of operational maneuvers, including various catapult takeoffs and arrested landings. ITF flight test operations also encompass general maintenance and fit tests for the aircraft and support equipment, as well as simulated maintenance operations.

As with the initial testing of any new aircraft, the goal is to collect environmental data through added instrumentation to measure the F-35C's integration to flight deck operations and to further define the F-35C's operating parameters aboard the aircraft carrier.

The ITF test team will analyze data obtained during flight test operations, conduct a thorough assessment of how well the F-35C operated in the shipboard environment, and advise the Navy to make any adjustments necessary to ensure that the fifth-generation fighter is fully capable and ready to deploy to the fleet in 2018.

"Our F-35 integrated test team has done an amazing job preparing for today. This will be one landing out of thousands more that will happen over the next few decades," said Lt. Gen. Chris Bogdan, F-35 Program Executive Officer. "For months, we've been working with the Nimitz crew, Naval Air Forces, and our industry partners, Lockheed Martin and Pratt & Whitney, as well as their suppliers, to prepare and train for this event. We plan on learning a lot during this developmental test and will use that knowledge to make the naval variant of the F-35 an even more effective weapons platform."

The F-35C combines advanced stealth with fighter speed and agility, fused targeting, cutting-edge avionics, advanced jamming, network-enabled operations and advanced sustainment. With a broad wingspan, reinforced landing gear, ruggedized structures and durable coatings, the F-35C is designed to stand up to harsh shipboard conditions while delivering a lethal combination of fighter capabilities to the fleet.

The F-35C will enhance the flexibility, power projection, and strike capabilities of carrier air wings and joint task forces and will complement the capabilities of the F/A-18E/F Super Hornet, which currently serves as the Navy's premier strike fighter.

By 2025, the Navy's aircraft carrier-based air wings will consist of a mix of F-35C, F/A-18E/F Super Hornets, EA-18G Growlers electronic attack aircraft, E-2D Hawkeye battle management and control aircraft, MH-60R/S helicopters and Carrier Onboard Delivery logistics aircraft.

The successful recovery of the F-35C represents a step forward in the development of the Navy's next generation fighter and reinforces Navy-industry partnership goals to deliver the operational aircraft to the fleet in 2018.

F-35C exceeds 100 catapults, arrestments during first week at sea

The carrier variant of the Lockheed Martin F-35 Lightning II combat aircraft has completed more than 100 catapult launches and arrested landings during its first two weeks of sea trials, pilots and officials told reporters aboard the USS Nimitz (CVN 68) on 13 November.

The two C-model test aircraft on board Nimitz , CF-03 and CF-05, have already satisfied 95% of the threshold requirements for the first of three rounds of sea-based Development Testing I (DT-I), according to US Navy (USN) officials. As of 13 November the aircraft had completed 102 catapult launches and 104 arrested landings with a redesigned tailhook, according to data provided by the F-35 programme office. The pace puts DT-I on track for completion ahead of the scheduled 17 November end date, said programme office officials.

Further, the F-35C has conducted its first night-flight, the Pentagon announced. "Lieutenant Commander Ted Dyckman piloted test aircraft CF-03 for the inaugural night-flight of the F-35C on 13 November," said F-35 programme office spokesman Joe Dellavedova.

The F-35C's unit price is about USD130 million, making it the costliest of the three variants, but the Pentagon's goal is to lower that price to about USD96 million by 2018 when the navy is expected to allow the aircraft to deploy operationally, said Dellavedova.

Meanwhile, the F-35C's highly anticipated automated landing system,'delta flight path', is proving very reliable thus far, according to pilots.

"It makes landing on the boat a routine task," said Commander Tony Wilson, the pilot who conducted the first F-35C carrier landing on 3 November. Pilots said the feature is somewhat similar to cruise control on cars. Landing on a flight deck "has always been fun and challenging", said Cmdr Wilson. "This makes it fun and routine."

F-22s and F-35s Fly First Operational Integration Training Missions

This is what Air Force generals have envisioned for decades. Two sets of fifth generation fighters flew side-by-side earlier this month to practice offensive counter air, defensive counter air and interdiction missions together over Florida out of Eglin Air Force Base.

It as the first time the F-35 and F-22 flew operational training missions together, Air Force officials said.

Both fighters have had a turbulent development and the F-35 is far from complete, but this was the vision. The F-35 and F-22 teaming up to combat a first world air force like China or Russia.

Air Force officials didn’t release many details from the training missions, but the photos sort of speak for themselves. Even the largest cynics of the program have to pause and consider the history of the two controversial stealth fighters flying training missions together.

F-35C Completes Initial Sea Trials aboard Aircraft Carrier
"The engineers responsible for the aircraft's control laws at Pax (Patuxent) River and Fort Worth have done a phenomenal job designing a carefree aircraft from the pilot's perspective," said Cmdr. Tony Wilson, DT I Team Lead. "The F-35C's performance on the ball was revolutionary, providing carefree handling on approach. The Integrated Direct Lift Control (IDLC) allows ball control like no other aircraft. The control schemes of the F-35C provide a tool for the below average ball flyer to compete for top hook. And, Delta Flight Path is an innovative leap in aircraft flight controls - this command enables the F-35 to capture and maintain a glideslope, greatly reducing pilot workload, increasing safety margins during carrier approaches and reducing touchdown dispersion."
Not much is known about flight control laws. But that they are logical rules that governs how a fly-by-wire flight controls system (FBW-FLCS) make possible stable and controlled flight for an aircraft, be it a jet fighter or an airliner.

Conceptually speaking, the human arm is a 'law', a physical law. It sets the limits on a person's ultimate reach and range of motion. In traffic, the 'STOP' sign, the lane demarcations, the roundabout, and other devices, are virtual laws governing how drivers safely negotiate each other. Physically speaking, the 'STOP' sign is not that imposing. It cannot stop a car from destroying it or a driver from ignoring it. The 'STOP' sign is a virtual law in the sense that it relies upon the driver's interests in surviving traffic that he will obey its commandment.

In a mechanical flight control system (FLCS), the push-pull rod is a law. So are the cable, the bell-crank, and other mechanical devices in the chain.

FLIGHT CONTROL MECHANISMS
FLIGHT CONTROL MECHANISMS

The term flight control refers to the linkage thatconnects the control(s) in the cockpit with the flightcontrol surfaces. There are several types of flightcontrols in naval aircraft; some are manually operatedwhile others are power operated. Manually operated flight control mechanisms arefurther divided into three groups -- cable operated, push-pull tube operated, and torque tube operated. Some systems may combine two or more of these types.
These mechanical devices, which includes the hydraulic actuator, set the limits on how much the deflections and how fast of the flight control surfaces. These devices are designed from the aircraft's original aerodynamics.

The fly-by-wire flight control system (FBW-FLCS) revolutionizes flight control designs in ways (understandably) unappreciated by the public. The laws (limits) are now no longer physical but virtual. Even the hydraulic actuator, the final physical limiter in the chain, now must have greater range of displacement in order to facilitate potential greater demands possible in the software that contains the flight control laws.

What was the first FBW-FLCS vehicle ? Not jet fighter, but vehicle ? How about the Moon lander ?

Apollo 11 Guidance Computer tech spec and how it worked - E & T Magazine
Translating the AGC's capacity into modern computing parlance can be misleading, but its magnetic core ROM stored the entire guidance programme in the equivalent of about 36 kilobytes. Each tiny ring-shaped core acted as a miniature transformer. Signals from wires running through a core were interpreted as a '1' while those running past it registered a '0'. Up to 64 wires could be threaded in or around a core.

Nothing was 'stored' in ROM when the computer was switched off, but once activated, it booted up within less than a second. It was a totally 'hard-wired' system, because the software was encoded as patterns of wiring, snaking in and out of the little ring-shaped cores, that could not be overwritten or erased.

The world's first FBW-FLCS aircraft was the experimental F-8 under NASA. But it was the F-16 from General Dynamics with its revolutionary deliberative unstable design that finally freed the FBW-FLCS from the mechanical constraints that existed since the Wright Flyer. Unstable does not equal to un-aerodynamic. Aerodynamics is about the study and exploitation of air flow over the surfaces of a body. The F-16 being unstable mean its body is more able than other designs to change attitude, or being more maneuverable.

NASA's experimental F-8, a combat proven fighter, was about exploring the reliability and INHERENT flexibility of those virtual flight control laws. NASA wrote those laws up to the physical limits made available by the F-8 and effectively proved that the move to virtual flight control laws is technically feasible and safe. General Dynamics took the concept further and made the transition quite necessary if anyone is to compete in aviation, military or civilian.

In human readable form, this is what a set of flight control laws looks like...

Airbus Flight Control Laws

For the F-35C with its 'Delta Flight Path' flight control laws specifically written for aircraft carrier landing, it is a great credit for the engineers who created those laws. They took in all the known factors involved in landing an aircraft on a carrier, from aircraft physical status such as flaps/slats/gear down, to airspeed within known range, to altitude, to angle of attack optimal for such a maneuver, to throttle position, to current weight, to ordnance level, and so many more, and must virtualize them to precision level necessary so that landing on an aircraft carrier, even at night, is: '...fun and routine.'

Navy's F-35C Takes Historic Step Forward Following Budgetary Turmoil | Military.com
"Instead of manually controlling thrust and pitch attitude, our flight control engineers have cut out the middle work so the flight path is controlled directly. It gives us spare capacity to monitor the other systems on the jet. We are landing the jet almost exactly where we want almost every time," said Cmdr. Christian Sewell, a F-35C test pilot.

Pilots try to land the F-35C in between the second and third of four cables arranged on the landing deck, Sewell explained.

One can only imagine the human readable form of the laws contains inside the 'Delta Flight Path' subset of the greater set of the flight control laws that overall governs the F-35.

God forbids, may be even USAF pilots can land on an aircraft carrier with ease. Sacrilege...Blasphemy...!!! :lol:

Just like the F-117 that STFU-ed its critics, the F-35 will also STFU-ed its critics.

Lockheed, Pentagon ink $4.7 billion deal for eighth batch of F-35 fighters

The Pentagon said on Friday it had awardedLockheed Martin Corp (LMT.N) a contract valued at $4.7 billion for an eighth batch of F-35 fighter jets that lowered the average price per jet by 3.5 percent from the last contract, and 57 percent from the first batch.

The Pentagon's F-35 program office said the deal includes 29 jets for the United States and 14 for five other countries: Israel,Japan, Norway, Britain and Italy.

Once production of those jets is completed, more than 200 F-35s will be in operation by eight countries, according to the office that runs the $399 billion F-35 program for the Pentagon.

The Pentagon has signed a separate contract valued at $1.05 billion for an eighth batch of engines built by Pratt & Whitney, a unit of United Technologies Corp (UTX.N), to power the jets. Pratt last month said the contract would lower the cost of the engines between 3.5 percent to 4.5 percent.

The program office said the new contract reduced the cost of the A-model airframe built for the Air Force, without the engine, to $94.8 million.

The cost of the F-35 B-model, which can take off from shorter runways and lands like a helicopter, would be $102 million, without an engine, while the Navy's C-model or carrier variant would be $115.7 million, it said.

The Pentagon does not provide detailed cost breakdowns for Pratt's F135 engine, given the company's concerns about proprietary data, but U.S. officials have said they expect the cost of the aircraft, with an engine, to drop to about $80 million to $85 million by 2019.

Lockheed's F-35 program manager, Lorraine Martin, said the latest contract showed the company was making steady progress in reducing the cost of the most advanced U.S. warplane.

Lockheed and its key subcontractors, Northrop Grumman Corp (NOC.N) and BAE Systems Plc (BAES.L), as well as Pratt, are all investing in various measures aimed at simplifying production of the jets and reducing the cost to build and operate them.

But the biggest driver in cutting the cost of the planes is the number of jets ordered in any given year.

Lockheed had hoped to finalize orders for two dozen more F-35 jets for Israel this year or early next, but Israel may halve that order to around 10 to 15 jets, a cabinet minister told Reuters earlier this week.

UK F-35B has conducted first tests with ASRAAM and Paveway IV weapons at Patuxent River Naval Air Station in Maryland, United States.

F-35B-trials.jpg


A British test team, has successfully completed initial trials with ASRAAM (Advanced Short Range Air-to-Air Missile) missiles and Paveway IV LGBs (Laser Guided Bombs) on the F-35B, the STOVL (Short Take Off Vertical Landing) variant of the Joint Strike Fighter, at NAS Patuxent River, US.

“Dummy” weapons (identical in shape and weight to the original ones) were tested during 9 flights in different configurations of both weapons types on two F-35Bs, flown by Billie Flynn, Lockheed Martin’s F-35 test pilot and Squadron Leader Andy Edgell from the RAF.

According to the team, which included personnel from BAE Systems, “the initial tests are an important step in integrating weapons onto the F-35B, allowing test pilots to understand how they affect the way the aircraft performs and handles.”

Such tests are the first step towards full interoperability of the two weapons, already used by the Royal Air Force on its existing fleet, with the F-35B, destined to enter in UK’s active service, with both the RAF and Royal Navy by 2018.

As already highlighted in the past, whilst carrying significant payload on external wing pylons makes the JSF more “convincing” as a multi-role platform, it makes the plane much less stealthy as well.

The United States is making a gigantic investment in the F-35 Joint Strike Fighter, billed by its advocates as the next — by their count the fifth — generation of air-to-air and air-to-ground combat aircraft. Claimed to be near invisible to radar and able to dominate any future battlefield, the F-35 will replace most of the air-combat aircraft in the inventories of the U.S. Air Force, Navy, Marine Corps, and at least nine foreign allies, and it will be in those inventories for the next 55 years. It’s no secret, however, that the program — the most expensive in American history — is a calamity.

This month, we learned that the Pentagon has increased the price tag for the F-35 by another $289 million — just the latest in a long string of cost increases — and that the program is expected to account for a whopping 38 percent of Pentagon procurement for defense programs, assuming its cost will grow no more. Its many problems are acknowledged by its listing in proposals for Pentagon spending reductions by leaders from across the political spectrum, including Rep. Barney Frank (D-Mass.), Sen. Tom Coburn (R-Okla.), President Barack Obama’s National Commission on Fiscal Responsibility and Reform, and budget gurus such as former Sen. Pete Domenici (R-N.M.) and Alice Rivlin, former director of the Congressional Budget Office and Office of Management and Budget.

How bad is it? A review of the F-35’s cost, schedule, and performance — three essential measures of any Pentagon program — shows the problems are fundamental and still growing.

First, with regard to cost — a particularly important factor in what politicians keep saying is an austere defense budget environment — the F-35 is simply unaffordable. Although the plane was originally billed as a low-cost solution, major cost increases have plagued the program throughout the last decade. Last year, Pentagon leadership told Congress the acquisition price had increased another 16 percent, from $328.3 billion to $379.4 billionfor the 2,457 aircraft to be bought. Not to worry, however — they pledged to finally reverse the growth.

The result? This February, the price increased another 4 percent to $395.7 billion and then even further in April. Don’t expect the cost overruns to end there: The test program is only 20 percent complete, the Government Accountability Office has reported, and the toughest tests are yet to come. Overall, the program’s cost has grown 75 percent from its original 2001 estimate of $226.5 billion — and that was for a larger buy of 2,866 aircraft.

Hundreds of F-35s will be built before 2019, when initial testing is complete. The additional cost to engineer modifications to fix the inevitable deficiencies that will be uncovered is unknown, but it is sure to exceed the $534 million already known from tests so far. The total program unit cost for each individual F-35, now at $161 million, is only a temporary plateau. Expect yet another increase in early 2013, when a new round of budget restrictions is sure to hit the Pentagon, and the F-35 will take more hits in the form of reducing the numbers to be bought, thereby increasing the unit cost of each plane.

A final note on expense: The F-35 will actually cost multiples of the $395.7 billion cited above. That is the current estimate only to acquire it, not the full life-cycle cost to operate it. The current appraisal for operations and support is $1.1 trillion — making for a grand total of $1.5 trillion, or more than the annual GDP of Spain. And that estimate is wildly optimistic: It assumes the F-35 will only be 42 percent more expensive to operate than an F-16, but the F-35 is much more complex. The only other "fifth generation" aircraft, the F-22 from the same manufacturer, is in some respects less complex than the F-35, but in 2010, it cost 300 percent more to operate per hour than the F-16. To be very conservative, expect the F-35 to be twice the operating and support cost of the F-16.

Already unaffordable, the F-35’s price is headed in one direction — due north.

The F-35 isn’t only expensive — it’s way behind schedule.The first plan was to have an initial batch of F-35s available for combat in 2010. Then first deployment was to be 2012. More recently, the military services have said the deployment date is "to be determined." A new target date of 2019 has been informally suggested in testimony — almost 10 years late.

If the F-35’s performance were spectacular, it might be worth the cost and wait. But it is not. Even if the aircraft lived up to its original specifications — and it will not — it would be a huge disappointment. The reason it is such a mediocrity also explains why it is unaffordable and, for years to come, unobtainable.

In discussing the F-35 with aviation and acquisition experts — someresponsible for highly successful aircraft such as the F-16 and the A-10, and others with decades of experience inside the Pentagon and years of direct observation of the F-35’s early history — I learned that the F-35’s problems are built into its very DNA.

The design was born in the late 1980s in the Defense Advanced Research Projects Agency (DARPA), the Pentagon agency that has earned an undeserved reputation for astute innovation. It emerged as a proposal for a very short takeoff and vertical-landing aircraft (known as "STOVL") that would also be supersonic. This required an airframe design that — simultaneously — wanted to be short, even stumpy, and single-engine (STOVL), and also sleek, long, and with lots of excess power, usually with twin engines.

President Bill Clinton’s Pentagon bogged down the already compromised design concept further by adding the requirement that it should be a multirole aircraft — both an air-to-air fighter and a bomber. This required more difficult tradeoffs between agility and low weight, and the characteristics of an airframe optimized to carry heavy loads. Clinton-era officials also layered on "stealth," imposing additional aerodynamic shape requirements and maintenance-intensive skin coatings to reduce radar reflections. They also added two separate weapons bays, which increase permanent weight and drag, to hide onboard missiles and bombs from radars. On top of all that, they made it multiservice, requiring still more tradeoffs to accommodate more differing, but exacting, needs of the Air Force, Marine Corps, and Navy.

Finally, again during the Clinton administration, the advocates composed a highly "concurrent" acquisition strategy. That meant hundreds of copies of the F-35 would be produced, and the financial and political commitments would be made, before the test results showed just what was being bought.

This grotesquely unpromising plan has already resulted in multitudes of problems — and 80 percent of the flight testing remains. A virtual flying piano, the F-35 lacks the F-16’s agility in the air-to-air mode and the F-15E’s range and payload in the bombing mode, and it can’t even begin to compare to the A-10 at low-altitude close air support for troops engaged in combat. Worse yet, it won’t be able to get into the air as often to perform any mission — or just as importantly, to train pilots — because its complexity prolongs maintenance and limits availability. The aircraft most like the F-35, the F-22, was able to get into the air on average for only 15 hours per month in 2010 when it was fully operational. (In 2011, the F-22 was grounded for almost five months and flew even less.)

This mediocrity is not overcome by the F-35’s "fifth-generation" characteristics, the most prominent of which is its "stealth." Despite what many believe, "stealth" is not invisibility to radar; it is limited-detection ranges against some radar types at some angles. Put another way, certain radars, some of them quite antiquated, can see "stealthy" aircraft at quite long ranges, and even the susceptible radars can see the F-35 at certain angles. The ultimate demonstration of this shortcoming occurred in the 1999 Kosovo war, when 1960s vintage Soviet radar and missile equipmentshot down a "stealthy" F-117 bomber and severely damaged a second.

The bottom line: The F-35 is not the wonder its advocates claim. It is a gigantic performance disappointment, and in some respects a step backward. The problems, integral to the design, cannot be fixed without starting from a clean sheet of paper.

It’s time for Defense Secretary Leon Panetta, the U.S. military services, and Congress to face the facts: The F-35 is an unaffordable mediocrity, and the program will not be fixed by any combination of hardware tweaks or cost-control projects. There is only one thing to do with the F-35: Junk it. America’s air forces deserve a much better aircraft, and the taxpayers deserve a much cheaper one. The dustbin awaits.
