The original objective was 6+g with a threshold of 5.3+g. Current threshold is 4.6. Observed performance of the heavier 240-3 configuration was 4.95g, sustained. The F-35 did not meet the planned threshold.
So as i understand the current performance of F-35 at Mach 0.8 and 15.000 feet is 4.95 G sustain ?
It’s not a problem per se.
But I repeat: the F-35 has a greater part of its reference wing area buried in the fuselage because its fuselage is wider than the F-16s. The actual F-35A/B wing area is only ~25% bigger. Hence wingloading comparisons are somewhat misleading.
Wing loading comparison is always misleading without respective lift coefficients, if we was to compare actual wing area only ( no body and engine) then PAK-FA wing is even smaller than Mirage 2000 wing
No, in this case allow me to correct you : you cannot say this about russian ones as they are blended wing bodies with podded engines, meaning that there is not any real fuselage there, just the so called stinger acting like the spinal cord in a vertebrate and that generate a lot of lift anyway.
F-35 is a blended wing body too
…silly DoD had no reason to lower KPP to get F-35 qualified, right ?
it didnt meet objective, it didnt meet threshold,
-no problem, just lower threshold and issue a standing order of coverup pep-talkThe US Department of Defense’s decision to relax the sustained turn performance of all three variants of the F-35 was revealed earlier this month in the Pentagon’s Director of Operational Test and Evaluation 2012 report. Turn performance for the US Air Force’s F-35A was reduced from 5.3 sustained g’s to 4.6 sustained g’s. The F-35B had its sustained g’s cut from five to 4.5 g’s, while the US Navy variant had its turn performance truncated from 5.1 to five sustained g’s. Acceleration times from Mach 0.8 to Mach 1.2 were extended by eight seconds, 16 seconds and 43 seconds for the A, B and C-models respectively. The baseline standard used for the comparison was a clean Lockheed F-16 Block 50 with two wingtip Raytheon AIM-120 AMRAAMs.
Did you miss garry post?
even with lowered KPP, F-35 still out turn F-16
you have to give it to warisboring: first they revealed F-35 cant keep up with an old F-16D,
we been over this already

^ isn’t it funny that when LEG (or must i say M&S ? or do you prefer Kurt Plummer.?) realized that he cant win the technical argument by throwing random acronyms around , he start a completely unrelated rant about Israel and immigration
I believe the USAF is lying through their teeth because they know the jet is worthless as a ranged platform and they are so bad at it that they cannot even keep their falsehoods straight:

Niemi explained the range advantage that sets the Lightning II apart from previous fighter designs. “One of the things I really like about the F-35 is the amount of fuel we carry, and with 18,000 pounds that is a lot of fuel. F-15s, F-16s, and F-18s don’t have those kinds of legs. The F-35 can get you to places they can’t because of its one engine versus the two engines of the other jet fighters.”For the quick two hour, ten minute jaunt from Florida to AirVenture, each fighter jet burned about 5,000 pounds of fuel at 270 knots. Niemi said typical approach speeds are 150 knots and strictly by a 13-degree angle of attack all the way to the ground. “It’s a real easy plane to fly and it has good powerful [air] brakes. At 100 knots it will sit down pretty good,” he said.
>>>>
First off, they don’t say what the distance is but they do say what the airspeed was. Two hundred seventy nautical miles per hour X2.15hrs is about 580 nautical miles.It is 1,087 statute or 945 nautical miles from Eglin AFB, Florida to Oshkosh, Wisconsin where the EAA airshow is always held.
RIGHT THERE, you have to instantly dismiss anything the USAF says as bogus because they have just lied to you about something as simple as linear distance which is _crucial_ to any figure regarding fuel consumption.
This assumption is hilarious because you dont know when he said 270 knots , is he referring to indicated airspeed or calibrated airspeed, or equivalent airspeed or true airspeed , it will make some big different there
since that is bizjet (if not cruise missile) arena of about .30pph, it is NOT correct for a jet which, at flight idle, is producing some 16,200lbf.
This assumption will only be true if you took the F-135 outside of F-35 , and put it on a stationary platform ( pole ) on ground , going higher in term of speed or altitude and everything change.We dont have the fuel flow for F-35 , but we can easily see how much fuel flow of F-16 changes with altitude
You people are led by the nose into prevaricative assumptions that are based on propagandist misdirection and you suck it up like it was mana from heaven without a moment’s contemplation of alternative source refutation. Let me help educate you.
If you want to educate anyone here, you need to learn elementary knowledge first.Your tactic of mixing a bunch of military terms to sound like “someone in the know” then mix it up with facts and factoids both real and imagined may fool people on Breaking Defense, but here, that simply doesn’t cut it.
Snip
Good post, but i dont think LEG understood half of what he said. He seems to be the kind of guy who happened to read some websites about aeronautic, learned some acronym, some terminology , then he just put everything together in his huge long post. And we know when the post is long and have alot of science sounding words, people often cant be bothered to check how much nonsense is inside of it. So he is free to write and bull…. ******however much he want. And hopefully, if he is lucky, some morons will think he is an expert and even copy paste his nonsense to others forum. He isn’t very lucky today when all his **** is called out lol
It seems I did not make it clear the reference to the clean PAK FA with a load out of internal weapons (and performance advantage) was in reference to the SU-27 family of fighters with an external load out of weapons only as the post I was responding to mentioned the need to double engine efficiency & I was pointing out there are other things involved.
.
The maximum ferry range of Su-27 isn’t with weapons
writing in caps will not make you more credible. just look at airline efficiency compared to 1970s. T-50 is built with most composites.
Iam asking for official information not some numbers from the tabloid where the editor dont even know the difference between miles and km. ( it quite sneaky of him to put his own interpretation number between the quote line)
Officially Sukhoi themselves haven’t release info about PAK-FA range, according to india official, their HAL FGFA ( Which is basically PAK-FA) max range is 3500 km on subsonic
I did not produce that range figure. remember it has twice the supersonic range of Flanker. so subsonic range of 1.5 times of Flanker will bring it at about 5400km is very reasonable.
TWICE THESUPERSONC RANGE IS NOT MENTIONED IN ANY OFFICIAL SOURCE ( AND SINCE ONE OF THEM SUPERCRUISE , THE OTHER DOESNOT, SO EVEN IF IT WAS TRUE IT DOESNT TRANSLATE TO 5400 KM RANGE )
just 25% aerodynamic efficiency over Flanker bring its range above 5000km.
25% AERODYNAMIC EFFICIENCY ISNOT THAT SIMPLE TO GET
Normally , i couldnt careless about your trolling but F-35 range on internal fuel is 2220 km , if PAK-FA can travel 2000 miles longer that would bring its range to 5440 km ,not a chance.You outright lying
Typical BS from Sputnik and JSR, why so surprise ?:highly_amused:
I have read it thoroughly.. You are obsessed with “winning” the argument by asking totally impossible-to-get nonsense which you know no one will provide..
So it isn’t impossible-to-get nonsense when Scar demand to see classified experiments? it isn’t impossible-to-get nonsense when he demanded to see F-35, F-22, B-2 RAS, RAM composition and absorbing capabilities?
Weaker/stronger doesn’t mean squat. What matters is whether you can reach your [political, commercial, strategic…] goals..
Too bad, we are discussing capabilities of weapons system here so all others factors that affect the out come of the war such as human, environment, politics are irrelevant, if let say Japan has a war with China, and their F-35 shoot down a bunch of J-10 with kill ratio of 100-0 but at the end they still cant reach their objective because of their citizen want the war stop, does that mean F-35 is less capable than J-10 in a war? obviously not
Oh, not this BS, again.. Your practice of constantly responding with an uninterruptable flow of requests for the most impossible “evidence” has gone beyond tiresome.. How much of that can you actually get by yourself?
If you read the thread before you comments then you will realize that i didn’t just requested all these information randomly out of no where, i request them because Scar said unless i can provide him classifieds information regarding B-2, F-35, F-22 radar scattering experiment , RAM and RAS absorbing capabilities then What LM said is BS. I simply mocking his double standard.
War is not a football match.. it’s not a contest about who kills more, it’s solely about reaching strategic objectives.. Have the US reached their objectives in Vietnam?
There are alot of factors matter when you trying to reach an objective, weapons equipment only play a certain part. Russia fail to reach their objective in Afghanistan too, does that mean their military capabilities is weaker than Afghanistan ? No
I’m not gonna provide anything before you.
Because you have nothing other than strawman argument
Mathmatical, sSimulation without concrete output numbers – is just a funny picture. It’s not like your comics, you know…
Actually there is number on graph ,and your RCS simulation lacking most important information regarding RAM and RAS , it is a funny picture too
And another one strawman – 8th or 9th in this discussion?! May be it’s time for you to stop lying?
That one was a fact actually not intended as an argument
Only after you show me something serious, instead of cool pictures.
So where is your solid data to prove the Russian radar can perform as advertised?
where is your solid data to show that continues curve doesn’t contribute much to B-2 stealthy characteristics at low frequency?
Where is your solid data to prove that F-22, F-35 doesn’t have RCS as claimed by LM?
Where is your solid data to prove that the Ukraine group have access to US government top secret information ?
Where is your solid data to show that F-22, F-35 RAM is the same as B-2 with no improvement ?
There is even a pattern published by Lockheed Martin for RAM that can absorb radiowave between 0.1GHz and 60 Ghz, where is your evidence that US stealth aircraft dont use it or it isnot enough to deal with low frequency radar?
What’s wrong is that your naive childish belief in wonder-waffe.
Hahahaha , childish ? look at yourself and your nationalistic bias
More than thousand of aircrafts lost from SAMs is pretty good, for SAMs, result.
Actually , most got shotdown by AA gun , not SAM
And finally, it doesn’t change the main fact – US losses were insasnely huge, for such a war in some tiny poor Asian country. “Self-confidence – mother of all defeats.” (c)
That Asian country was supported by China and Russia , and if we actually take kill-death ratio into account , US didn’t really lose
Looks like someone confused strategic ABM shield with a Patriot tactical SAM.
PAC-3 is part of US ballistic missiles defense system along with THAAD and Aegis system
So, i think i wouldn’t be upset with some useless SAMs if i have such a wonder-waffe as super-duper stealth. Or, in other words – if stealth really was a wonder-waffe as you see it.
Even an AK , a T-80 , a IED can be a threat
Now you see?! Hundreds of stealth fighters and bombers in service don’t change the fact that in reality, behind its bravade and fairy-tales about 0,000001sqm, USAF still sees these SAMs as a real threat.
US don’t just operate only stealth aircraft and it is just the same case when Russia moaning every time US improve their missiles defense system
May be some fanboys should learn to not to confuse advertising with reality?
You should take your own advice first
I’m glad that you admit that there is no solid data – only empty screams sort of “it’s insect! ZOMG!!!”BTW, you can find your answers right here.
actually i did provide data, manufacturers claims and simulation, obviously me, a sane person wouldn’t claim that is solid because RAM and RAS are among the highest top secret information
On the otherhand, despite much screaming and yelling you dont provide anything substantial
And i can say that RCS is fluctuated between -20 and 10dBsm. Show me tables with average and median RCS, as it made in Sukharev’s group research.
Nice try , at first you demand to see simulation, now you change the goals and demand to see table, :highly_amused: while you are at it why don’t you demand the simulation to be done by a group of Ukrainian as well?
not always, but mostly…yeah. Nation of businessmen, nothing more or less
.
The double standard is strong with this one, no wonder you hate stealth :highly_amused:
Only after you provide some solid data on RCS of all these planes – coz this is a starting point of all this discussion.
So what is solid? where is your solid data regarding Russian radar system?
What is wrong – it’s your manner to place the words i nver said, to my mouth
.
What wrong is your double standard
Yeah, that’s what USAF was thinking of before Vietnam – we know what to do…Soviet SAMs cooled their temperament pretty fast. Remind me, how many thousands of airplanes they’ve lost in that little Asian country? 2 or 3 thousand?
Actually most aircrafts in Vietnam was shot down by AA gun not SAM, they lose 1700 to enemy action over 5.3 millions sorties, that is like 0.03 % ratio
It’s just your fantasy. Noone and never in Russia was upset by Patriot near our borders.!
Yeah sure, they just bitching everytime US try to improve their missiles defense
But US do! Then why be so upset?! Send your invisible wonder-waffe and simply destroy these useless SAMs!
So you think country will just attack each other for fun?
