Air Force F-35's taking part in "Checkered Flag" exercises:
"a large-force exercise which gives a large number of legacy and fifth-generation aircraft the chance to practice combat training together...
F-22s, T-38 Talons and QF-16 aerial targets from Tyndall; F-35s, an F-15E Strike Eagle, F-15Cs Eagles and F-16 Falcons from Eglin AFB, Fla.; F-16s from Shaw AFB, S.C.; B-52s from Barksdale AFB, La.; an E-3 Airborne Warning and Control System (AWACS) from Tinker AFB, Okla.; and F-16s from Eielson AFB, Ak. are supporting the exercise"

Sounds like work up testing in preparation for IOC.

F-35B being tested on "expeditionary airfields" by USMC at 29 Palms and Pendleton.


Reading 17 days for build this track for used F-35B !
“It took my Marines 17 long days to ensure the pad was put together.”

With also many support equipment, specials only USA can get it much means required.

No possible use metal plates as with AV-8B, all USMC fighters bombers use it since WWII, remenber i believe a pic posted by Jeff with it ?

Otherwise more fast take an ennemy airbase if is possible... :)

When you see a complementary piece on the F-35 program, you know the tide has finally turned. A good year for the program, no doubt about that.

Does anyone have any information of when the F-35C will be back aboard ship for more quals?? when are Naval Aviators going to bring the C forward for IOC?

Here, you are missing the point? They don't need to, for example the F-35B has a design load limit of 7 Gs, the F-35C 7.5 Gs, and the A model 9 Gs, reflecting the different operational philosophies of each of our different services? on what is basically the same airframe.

The fact that the USAF has dispensed with OVT, while retaining a 9G airframe with a gun is instructive?? yes the fact the the USMC is happy with a 7G STOVL airframe is also instructive?? yes, and the USN with its larger, heavier, carrier qualified 7.5G airframe is also instructive. It also would be well to bear in mind that while the A model is an air-superiority aircraft, its primary design still bears the marks of its A2G birth, and it is truly a multi-role aircraft.

I don't think it is a matter of philosophie/tactic restrictions due to a common Fighter for 3 services in more wanted less expensive especialy with only a reactor, without VT also supercruise capacity and in more some restrictions for a VSTOL variant.
More easy to ask now ofc but definitely AF and Navy would have a better fighter mainly for A2A/ dogfight ( agility and low speed ) if each service had his fighter as by ex F-14/15 a lesson learned for next 6th gen.
There had already been a failure in the past with the F-111.

For dog fight F-35 less agile but nomaly her electronic systems for situational awareness on 360° the DAS compensates, the pilot look more fast.

After for max G load i am not a specialist but i think F-35C wings can cause an inferior max G load ?
Also F-35B is a little less powerful as others thrust of ~ 18,5 t vs 19.5.

Other things F-35/F-22 with F-135 are very greedy, F-119 again more, EJ-200, M-88 ( the best with F-414 : 4t/hour with AB 12) and F-404/414 also get a very good consumption and despite 2 reactors for Rafale, Typhoon, F-18 her consumption remains clearly inferior.

Maybe also finaly the supercruise capacity is a problem for consumption need very powerful reactor which ofc consumes more, when i see the F-22 confirmed also by her CR of 1200 km which is good but inferior to F-15 while it is as big.

Talking recently for Rafale same for Typhoon they are for size medium fighters which get capacities of a heavy fighters and consumption help weigh 7 t of less as a F-35 whose 3 t of fuel, ~ 5 vs 8.1 and have a better combat radius as a F-35A max 1400/1100 but CR of F-35 is good better as a F-16, 900 km.

After a F-35 is a stealth fighter and need for it carry a part of her armament in 2 internal weapons bays sized for host big 907 kg bombs and this will take up space and weight.

He get a big fuselage more big as others fighters coz it.

AF Brat what do you mean for supercruise, really interesting for A2A, AB is not sufficient ?

AB : Afterburner

I think the F-15, EF, Rafale etc. combat radii are including drop tanks, whereas the smaller F-22/-35 ones are on internal fuel only. The -22 & -35A/C run on about 8,2-8,5t on internal fuel, an F-15 on 6,1t and EF around 5t.
I guess under comparable high-subsonic cruise conditions these engines brun roughly the same amount of fuel per thrust delivered. Of course an F119 at mil power will burn quiet a bit, but of course it will get you whereever 1,5times faster.

I also don't think a common design for Navy & Air Force are the issue. As the Rafale pretty much perfectly demonstrates. The problem is STOVL for the Marine Corpse requirement.
F-111A & F-14 are not fitting examples, IMO. The F-111 was a large fighter bomber, that later on was supposed to be put on a carrier for multi-purpose (mainly interceptor) duty. If you design an air suppremacy fighter from the get go, a land & carrier capable design can be achieved for 6th gen, I believe.

In general I do believe that having a common fighter for the three services does "handicap" the capabilities of each aircraft, and the STOVL really throws a monkey wrench into the works??? and I believe quite a few SDF members agree?? BUT

and it is a Big BUT, Jeff is actually correct in asserting that the compromises are not so great as to cause a "train wreck" and that the economies of scale are in fact today, bringing costs down, to the US and her Partners. So even though in principle I agree with master Delft, that three airplanes would have been better, I have seen the wisdom of Master Jeff's approach, and love the fact that all of these aircraft are getting produced on the mile long assembly line in Fort Worth, and they are being "cranked out" and costs are dropping rapidly, and these aircraft are built to very fine tolerances and with very accurate production tooling, this will pay dividends.

As I pointed out, each of these airplanes have their own "character", as noted by the design Max G of each version, while you are likely right that the larger wing and tail of the C may in fact lower the G limit, it is the extra weight and structure overall that have actually done that?? Load an A up to C weights, and you would also have to lower the Max G of that heavier A model.

Now, if I could could manipulate LockMart, I would build a big wing A, with the larger wing and horizontal stabs, but it would be heavier, slower, and have a lower G limit. I believe I would gain fuel, a slightly quicker Pitch transition, lower take-off and landing speeds, and most importantly, a higher service ceiling??? I just like big wings, like the F-15 as opposed to the F-16, the F-15 is just an awesome handling and flying aircraft, with very few bad habits, the F-16 didn't earn her moniker as the lawn dart for nothing?? but everything is a compromise, change one thing on an aircraft, and it affects 15 different operating parameters, possibly some in a very negative way??

Supercruise is a big deal, sad the F-35 will not have that capability, but accelerated to Mach 1.8 and then pull the throttles back out of burner, and you will prolly have 10 minutes or so of supercruise in dry thrust??? and a commensurate fuel savings for those ten minutes?? even though you will burn a bunch accelerating her to Mach 1.8?

All good points gentlemens

and the STOVL really throws a monkey wrench into the works???
Yes it is confirmed this special variant caused the most problem to do the F-35, logic.


I think the F-15, EF, Rafale etc. combat radii are including drop tanks, whereas the smaller F-22/-35 ones are on internal fuel only. The -22 & -35A/C run on about 8,2-8,5t on internal fuel, an F-15 on 6,1t and EF around 5t.
I guess under comparable high-subsonic cruise conditions these engines brun roughly the same amount of fuel per thrust delivered. Of course an F119 at mil power will burn quiet a bit, but of course it will get you whereever 1,5times faster.
Yes CR with FT for F-15, EF, Rafale with 2 FT F-22 have one of ~ 1400 km others ~ 1500, and 1400 with subsonic speed, A2A weapons mainly, maximum CR after much parameters for the range which is definitely the more difficult data to find coz range depends mission profiles, weapons, speed ... but possible with some but few good sources find data enough precise.
Others CR : F-16A/D 930 km. F-22 with int fuel 1170 km.

F-35A also with internal fuel, subsonic 1100 km, C : 1150, B : 850 km a AV-8B 500 a difference even with F-18C also used by USMC 700 km
B carry much less fuel clearly with STOVL system 6.1 t, A 8.3 and C with large wings more as a F-22 8.9t vs 8.2.

For finish CR comparision Su-27 9.4t/1200 km, Su-30/34 9.7/1500, ( Su-34 fuel 12t but more heavy 45t ! ) Su-35 9.7/up to 1800 ! the best with but no sure ofc T-50, J-20 this three get a very long range.

Then F-35 is good ofc internal weapons bay take place and he carry less fuel in more it is less big as the 3 others stealth fighters.

With a marked improvement capabilities especially for USMC Aviation.

Next time comparison btw F-35 and fighters he replace.
