F-35 JSF Flight Test Update

So, Lockheed Martin just released the latest numbers for F-35 Joint Strike Fighter flight testing.

Here’s the quick and dirty from Lockheed:

October was the busiest month for flying in the history of the F-35 flight test program, with F-35 aircraft executing 122 flights. The F-35B aircraft known as BF-2 accomplished 22 flights, the most ever for an F-35 in one month.

  • F-35Bs completed their 500th flight on Sept. 30. In October, F-35Bs executed the most vertical landings (73) for a single month in the history of the flight test program, including the 200th vertical landing for the program Oct. 4.
  • AF-12 and AF-13 F-35A conventional takeoff and landing (CTOL) aircraft were delivered to the 33d Fighter Wing at Eglin Air Force Base, Fla., on Oct. 19 and 26, respectively. This marked the fifth and sixth delivery of CTOL jets to Eglin and the 12th overall delivery of an F-35 to the Department of Defense in 2011.
  • As of Nov. 3, F-35C carrier variant (CV) jets had executed 59 successful catapult launches and three arrestments.
  • F-35C aircraft achieved 200 flight hours on Sept. 22.
  • The F-35A known as AF-1 achieved the F-35’s maximum design limit speed of Mach 1.6 for the first time on Oct. 25.

Cumulative flight test activity totals for 2011 are provided below:

  • F-35A CTOL jets have flown 407 times.
  • F-35B STOVL aircraft have completed 296 flights.
  • F-35C CV jets have flown 134 times.

From the start of flight testing in December 2006 through Nov. 3, F-35s flew 1,432 times, including the production-model flights and AA-1, the original flight test aircraft.

  1. Have we ever bought planes before flight testing before?

  2. Only in the last 20 years or so. Back in the early days fair competitions were held when the companies paid for most of the development rather than the taxpayer. Now thanks to the stranglehold these companies have over politicians we somehow find it economical to pay for all the development and continuing cost increases.

  3. "As of Nov. 3, F-35C carrier variant (CV) jets had executed 59 successful catapult launches and three arrestments."
    59 out, 3 back…hope those numbers are much closer when they're out at sea!

    Do see the B has over twice the flights of the C. Wonder if L-M and the DOD are shifting focus to the B to save it from cancellation.

  4. From these test results, Lockheed's F-35 is demonstrating that all of the hard work to get the fighter jet to this point is paying off especially the trust that Marine Corps' Commandant General James F Amos had about the performance capability of the STOVL variant of the F-35 fighter jet; now the pressure will be pushed back to the Obama Administration to whether buy the desperately needed stealth fighter jet or wait for the next Presidential Administration to make the decision.

  5. Is this a real picture? If so what happened to the plane?

  6. Max speed of the F-35A is Mach 1.6? Seems kinda slow vs. past aircraft.

  7. I'm not sure where you get your info, but the F-16 can hit IMN 2.0 when slick. However, as somebody noted, it runs out of gas shortly after that. Also, I would note that no aircraft is going to drop bombs, or anything off of the wings save in emergency only, about around IMN .90. Just doesn't happen.

    I would say, from my experience, that super high top end speed is cool on the books, but rarely useful. Acceleration, you know, "the thrusties," is a much better quality, which the F-35 has in abundance, from all accounts.

    Best.

  8. The speed is comparable to the F-18C, which is slower than the MIG-29, MIG-31,
    SU-27, and so forth. The plane may be more manuverable than the Russian designs, but it can't out run them. The F-22A on the other hand is designed to
    both out perform and out manuver any Russian design. This aircraft is built like the strike fighter where speed is not paramount. The real world ACM is usually at subsonic speeds anyway.

  9. 1.6 mach is 1228 mph. (mach defined as 768 mph in dry air at 68 deg F. at sea level)

    The stealth technology, maneuverability and advanced systems better be GREAT because it sure won't out run a number of current Russian and Chinese AC and their copies.

  10. The F-35 is the only fighter that you can zap the guy coming up in back of you. 100% situational awareness. It is time to get them in service and in "Red Flag". No one in their rigrt mind would want to go against it.

  11. At 35,000 ft+, Mach 1.6 is approximately 1060 MPH (speed of sound at the stratosphere is close to 665 MPH)

  12. I guess the F-35 flies at around Mach 1.1 at sea level (850 MPH)

  13. I don't get it that after so many billions spent on the F135 it doesn't have a peacetime/wartime setting. Most modern engines have it, the EJ-200, M-88, F100-PW-232, F110-GE-132.

    The F135 has been tested at 50000lbs static, so there is sufficient margin to exploit something like 10% more thrust with a wartime setting.

    10% more thrust would mean probably the ability to supercruise with the F-35A at least, plus 10% more thrust to weight ratio in dogfight.

    The abiblity to supercruise is more important than absolute top speed because the F135 at full thrust must have a huge IR signature.

    Mach 1.6 is't bad fully loaded. Try to get an F-15, F-16 or F-18 up to mach 1.6 with a targeting pod, jamming pod, missiles and wing tanks. The F-35 has all this inside. I bet a F-16 would have a hard time getting to mach 1.2 with this load and the F-18 SHornet wouldn't even break mach. The mach 2 to 2.3-ish speeds the MIG/SU aircraft is clean not loaded. TSFG

  15. I find the down grading of this plane over whelming to say the least . There seems to be a fixation on speed not the overall feature's presented and the rolls that are to be filled with this aircraft maybe it will fail and then maybe not we should give those building the aircraft some respeck and be a little more positive in this project.
