F 35 expanded its AoA enveloppe up to the 50 deg. limmit in just 4 flight.
Lockheed Martin Press Release:
An F-35A Lightning II conventional takeoff and landing (CTOL) aircraft rapidly expanded its high angle of attack (AOA) test envelope to its 50 degree limit in only four flights during recent flight testing here.
F-35A test aircraft are limited to AOAs of 20 degrees until their controllability is proven at a higher AOA limit of 50 degrees.
The ability to rapidly progress to the maximum AOA indicates a sound aerodynamic and flight control system design.
High AOA testing will continue on the F-35A for several months testing the capabilities of all design loadings and the flight control system.

128 million includes initial spares and support.
OTOH, if lifecycle (I suppose 30 years?) spares and support were included, that would be 238 million (http://defense-update.com/20120505_us-congress-formally-notified-of-japans-f-35-purchase.html ). But this amount is not payed before delivery.
1º The cost for the entire RAF Typhoon Program per the most recent official NAO document, “Major Projects report 2011” is precisely 18,159 Bilion pounds. It covers the development and procurement of the 160 Phoons.
It’s still a high price–175 million each. More expensive then an F 35.
And remind me please, if you know, is the F-35 figure for an aircraft with an engine or do we have to add the cost of the engine to the $120m to get a real price?
The weapon system cost for the first F 35 exported is 128 million (engine included,. BTW). : http://www.reuters.com/article/2012/06/29/us-lockheed-fighter-japan-idUSBRE85S0VE20120629
That is the point. Without the related details like length and flight-level of each leg you will get “the desired” mission range and can secure that by an allowance of -30%. The problem with the reality is you operate just the smaller part of the mission in a high threat zone and by that you are much closer to the claimed -6% of the other fighters. 😎
There is a reason why the F 22 (and F 117) are flying high and the F 15 E is flying a hi/lo/lo/hi profile. The later is obliged to do so, if he wants to survive the mission.
Anyone know that a high altitude flying F 15E has an impresive combat radius: ~ 900 nmiles without EFT (but with CFT) and 1200 nmiles (EFT+CFT).
The chart about the range of the F-22A shows how LM has cooked the numbers. The reader has to ignore that and to look into the related details reduced to a minimum ( f.e. the hi-lo-lo-hi mission profile of the F-15E without the exact height and distance) to work up his own mind about that. 😡
On the contrary, the chart shows honesty ! If they would forget to mention the hi/lo/lo/hi plofile for the F 15E, that would have been cheating.
But to get back on topic. A lot of stuff regarding the F22 and F35 is pure marketing BS.
F35 will have better manuverability than the F16: That claim is revoked. Yes, it handles better than a F16 with drop tanks and heavy weapons but with light AA load it will be outperformed by the F16 (aka a F16 without JDAMs and without drop tank… sort of what one would expect to have dropped in a dogfight.)
Pro F35 source: http://whythef35.blogspot.se/2012/06/first-non-test-pilot-trained-on-f-35.htmlAnd the list goes on about stealth effectiveness, costs, the EODASS with TV-helmet etc.
Im confident that the F35 is the most sophisticated jet around and that it is hardest to detect on radar. Does this categorically make it the best fighter? Probably no, in some aspects yes, in others its even worse than the current fleet. Thats just how it goes.
If you read carefully , Lt Col Lee Kloos says that The F-35’s acceleration is “very comparable” to a Block 50 F-16. “Again, if you cleaned off an F-16 and wanted to turn and maintain Gs and [turn] rates, then I think a clean F-16 would certainly outperform a loaded F-35,” Kloos says. “But if you compared them at combat loadings, the F-35 I think would probably outperform it.” How about comparing an F 35 and an F 16 both with 2 AAMs and 1/2 fuel? I wouldn’t recomend you to bet on the F 16.
Stealth isnt a silver bullet, it is a countermeasure against one threat. In the F35 (and some extent for the F22) stealth has been adopted at the cost of other performance. The Pak FA is a compromise in the other direction where flight performance is the top priority and radar stealth comes in as second priority. If we want to keep the debate civilized we have to acknowledge that every design has pros and cons and are results of compromises. The F35 is NOT an exception!
No one said that stealth is a silver billet. But stealth, contrary to what many believe, does not lower other parameters (I’m not talking here about first gen. stealth — F 117). For once, in the F 22 case it didn’t stop it from being a fast plane and a superb dogfighter. In F 35, there are other demads (big fuel lod, big internal bay to carry huge 2000 lbs bombs, as much commonality as possible with STOVL & carrier variants) that limmit to some extent the kinematic performances. Imagine the same jet, but without the internal bay (just hang the goodies under the wing!) and with the internal tank tailored for a fuel load of ~ 4.7 t of (such as Rafale or EF). And these with a 43,000 lb engine…
Not that the USAF chiefs didnt screw its fast jet fleet by failing to recognise/adress the cost issues with the desired “all LO/VLO fleet”, but the civilian leadership is far from being an inpolute group of angels. Barrel pork politics in Pentagon acquisition policy has an awfull lot to do with “wich state profits the most”.
Exactly! You should spread the aquisition in as many states as possible, in order to win Congress representatives from those states, thus ruining one of the strongest advantages of US firms– a simplified logistic chain. You should bring some small&medium companies, also to throw in some minorities owned companies, and so on.
I think you’re having a quite selective memory. Most of the talks regarding maneuvrability of the F-22 were not aimed at the capabilities of the aircraft itself rather than at discrepancies between the actual performance and the alleged claims coming from the fan camp. It is the same situation as we got with the F-35 today – the plane as it is is not nearly as bad as it is quite far from the PR myths surrounding it..
P.S. The F-22’s ”Cobra” looks somewhat fishy as the Raptor gains altitude at the same time, which looks just weird.
I can see that you weren’t a member back in 2003-2005 🙂
Still that cheap nonsense claim about politicans.
Really? There was an USAF chief of staff sacked because he insisted on more F 22.
It’s not like the Congress set a limmit (in $$$) and the USAF can do what it really likes with.
In F 35 case, the export perspectives weight at least as USAF real needs.
What he actualy said was that a fleet of F-22/F-35 mixed with less expensive aircrafts, read, Vipers, would fill the bill perfectly. And
thats not your point…
He said this (longer range, no SC, no TVC, IR sensors) about the F 22. I agree partially with what he said about Afg. — even an F 16 is to much. Drones would suffice. OTOH, hoping that any future potential ennemy would be similar to Afgan talibans would be insane.
Europeans? Wheeler is from Luxembourg (yes, that chap), right?
Were you reading this forum then? Because i can remember that some of the worst “offenders” were American (never mind the Aussies…)
That happened not ony in this forúm but generaly speaking everywere.
DJcross referes to posters on this forum, or at least this how I interpreted his post.
What mistifies me is that there´s some sort of “cost blindness” in the USAF. Two decades ago they went for a total LO/VLO fast jet force, now they ended up with a geriatric combat force, a handfull of stealth combat jets and a reduced number of sqn´s. That on a force that has a bigger budget than the second biggest MOD on the planet, the Chinese one!
And seems they didnt learn a thing…
It’s not USAF fault. Blame politicians. However, ~ 650 F 16 C/D (and these are relative new, not at all geriatric) has been CCIPed, some 300 of them will receive AESA, improved EW, etc. Also 170 F 15C (these are indeed a little bit old) +200 F 15 E (these ones are newer and have 16,000 hours of life –they are sort of teenagers in USAF fleet :D)will be also upgraded with AESA, new EW, IRST.
Sod it, in my view (not worth a dime) that chap Christopher Niemi should be made USAF procurement boss.
My friend, any person with a little common sense will be a better USAF procurement boss…
Are they? Lol.:D

Coming from their own midst..
What a commie traitor!
– Lets crusify him the the wall for this!!
Did you read the article?
He said that the F 22 is too A-A specialized:
The aircraft’s maximum range is slightly superior to that of the F-16 but significantly inferior(*) to that of the F-15C, which it was designed to replace. This fact has three important consequences: operational missions need more air-to-air tanker support, the F-22 has a limited ability to deeply penetrate hostile airspace, and pilots cannot take full advantage of the F-22’s supercruise capability. The aircraft has also proven more difficult to maintain than originally anticipated. The Air Force acknowledged that the F-22’s “radar-absorbing metallic skin is the principal cause of its maintenance troubles, with unexpected shortcomings.” The service needs to maintain these coatings continuously to ensure the combat readiness of F-22s, thereby significantly increasing the necessary maintenance manpower (and cost). Moreover, even traditional (non-stealth-related) maintenance rates proved initially higher with the F-22 compared to those of older fighters. However, rates have improved vastly as maintenance personnel have acquired more experience. For example, the mean time between maintenance amounted to .97 flight hours in 2004, but that for newer F-22s has recently increased to 3.22 flight hours.
(*) I suppose that he meant inferior to the F15 with 3 EFTs
However, he praises its qualities:
In terms of performance, the initial operational test and evaluation in 2004 The F-22 Acquisition Program found the F-22 “overwhelmingly effective.” Air Force analysts reinforced this evaluation recently, estimating that the F-22 exchange ratio is up to 30 times better than that for F-15s, F-16s, or F/A-18s in similar high-threat scenarios. Although fourth-generation pilots are used to “seeing” nonstealth fighters 50 miles or more away with their radars, they typically fail to detect F-22s with their radar, visually or otherwise. Today’s F-22 clearly excels at its originally designed air-to-air mission, reinforcing the fact that stealth enables tremendous advantages in the radar-dominated environment of modern aerial combat. Further, the F-22 has demonstrated a capability to conduct air-toground attack in high-threat environments where fourth-generation fighters simply cannot survive. Advanced surface-to-air-missile systems such as the Russian S-300 (North Atlantic Treaty Organization [NATO] designations SA-10 and SA-20) are the deciding factor in these environments. The S-300, similar to the American Patriot surface-to-air missile, has been operational since 1980. Although no Middle Eastern country currently possesses S-300s, Iran has expressed interest, and both China and Russia have fielded large numbers of them. This system can engage fourth-generation fighters at ranges exceeding 100 miles. A single S-300 battalion has the potential to render F-15Es, F-16s, and F/A-18s incapable of striking targets within a circle approximatlly 200 miles across. Additionally, the follow-on S-400 (NATO designation SA-21) further improves maximum engagement range. Fortunately, F-22s can utilize their stealth to operate effectively well inside the maximum engagement ranges of these systems
And he said that the F 22 should be designed differently:
If the service’s leaders had realized that surface-to-air-missile systems were eclipsing air-to-air threats as the primary danger to future air operations, they could have better leveraged the investment in ATF demonstration/evaluation to counter weapons like the S-300. The ATF’s stealth made the aircraft inherently more survivable against these threats, but it lacked a robust air-to-ground attack capability to target them. Furthermore, niche air-to-air capabilities such as thrust vectoring and some specialized avionics could have been eliminated to reduce cost and weight. Range should have received more emphasis, possibly even at the expense of supercruise. In addition to JDAMs, the Air Force should have added air-to-ground radar, Link-16 data-link transmit capability, and an infrared targeting sensor. These modifications would have greatly enhanced the F-22’s utility in threat environments dominated by surface threats without degrading air-to-air performance.
So, more range, no SC, no TV, AG radar modes, IR sensors…sound like an aircrfat I know…:p
BTW, DJcross refers to the threads prior to 2005, where many posters (of course Europeans), described the F 22 as a non-maneuvrabile airplane (because the compromises made for steallth :p), a plane that will never be able to pull a Cobra. Of course, once the F 22 appeared in airshows, the posters were silenced. Bur of course, the same persons had an orgasm when the F22 “choke its pilots”, or when some idiot reporters comme with the “1 trillion dollar” programm. OF course some detailes escape them, like that the sum its all the US tri-services will spent for 50 years of manufacture/operation of 2500 planes…
I think its fair to assume that the Gripen E with AA-load (range 1600km or >860nm) will be able to fly at above mach 0,9.
I corrected my initial post — I did not read carefully. A gripen NG won’t be able to fly for 860 nmiles above mach 0.9. 3 EFTs won’t let this.
High up in optimum conditions an “eagle-eye” can spot a small fighter at 10 nm distance at best. Worse atmospheric conditions and at lower levels that will shrink to much even lower limits when hitting zero in clouds or at night. WVR is just the distance some IFF can done by eye-sight or where the “short-range” IR-AAMs can be used.
I think you know that IR AAMs can be cued by radar. A decent radar has some 3 radar modes for WVR: supersearch, boresight and vertical scan. With radar you can “spot” a small fighter longer than 10 nm
BVR weapons with radar support can hit targets behind the 10 nm limit in all atmospheric conditions. Before the AIM-120 the IR-AAMs were the preferred choise for faster instant use and much cheaper as well.
Without the related details non serious can claim we had a WVR or BVR shot. That 10 nm limit is just a fictional one to distinguish between the shorter range IR-AAMs and the longer range AAMs fired behind that limit. All that shots are BVR whatever the details were. 😉
I said myself that many of the “BVR” shots were BVR only because the target was running from the shooter. It was a BVR because you have no chance to kill it with an IR AAM, but it was a WVR in regard of distance. What I said was to correct the other poster who said that most of the kills were with IR missiles.
Please, read my post again… It says that:
– the NG can have more range than the F-35 (.. read with the wet bags)
– the NG can be much faster, lighter and more agile than the F-35 whenever the need arises (… read after having jettisoned the wet bags)Understood now?
OK, I’ll try it differently:
-you fly with EFTs, which gives you an combat radius of ~ 715 Nmiles, but it takes you longer to arrive “on station” compared to a clean F 35;
-you fly with one EFT and 4-6 AAMs at 1.2M in SC, but you won’t go more than 200-250 Nmiles;
Besides that, I still think that the Gripen can outrun the F-35 even with one EFT but that is another story and not a subject to this debate.
:p
