Citat:F-35A Dogfight Performance
Much has been written about the F-35A’s performance in an air combat environment, and while it is important to see how well it stacks up against its fourth-generation predecessors, there are some important facts to keep in mind in any comparison. The F-35A is still under development, and incremental design restrictions limit the G-loading that pilots have to 7.0 Gs. The fly-by-wire design is predicated on software control laws (CLAWs) that act as a governor to limit pilots from max-performing the jet in a way that could cause it to go out of control.[20] For purposes of this paper, those limitations were taken as is, and pilots were asked not to speculate about how the jet will perform when those restrictions are lifted.
The energy and maneuverability (Em) performance of fourth-generation fighters is very often exaggerated by the idea that these fighters fly combat missions in absolutely clean “airshow” configurations. No fourth-generation jet in the U.S. inventory (or any other) goes into combat that way, and most will carry significant external stores (munitions, fuel tanks, and targeting pods) in order to accomplish their mission. When pilots know they are about to enter a dogfight situation requiring the best Em their jets can deliver, they will jettison fuel tanks and unexpended bombs, but almost every pod, rack,[21] or missile rail is permanently affixed,[22] adding significant un-jettisonable weight, drag, and RCS.
If stores and weapons are jettisoned prior to hitting air-to-ground targets, pilots will fail in their primary (multirole) tasking. Even post-jettison, the G-restrictions associated with targeting, forward looking infrared (FLIR), and HTS pods will remain and generally restrict jets to 8.0 Gs or less. While most fighters still perform adequately in those post-jettison configurations, air combat Em performance suffers considerably.
A Direct Comparison. Thirty-one experienced pilots currently flying the F-35A were asked to rate the energy and maneuvering characteristics of their previous fourth-generation fighters in a combat configuration throughout the dogfighting maneuver envelope in a combat configuration[23] after jettisoning their external stores. They were then asked to rate the performance of the F-35A using the same scale, with fuel and internal munition loads associated with a combat loadout[24] under their current G and CLAW restrictions.[25] The F-35A compared well to the four other fighters (F-15C, F-15E, F-16C, and A-10) in most every regime. (For the total results and responses from the pilots of each respective fighter, see Chart 1.)
Each pilot was then asked to select which fighter he would rather fly in combat if he were to face a clone flying the other jet in six different air-to-air situations. (See Chart 2.) If the pilot selected an F-15C in a short-range setup, for example, he felt he could outperform a pilot of equal abilities in the F-35A. Pilots selected the F-35A 100 percent of the time in beyond-visual-range situations and over 80 percent of dogfighting situations where energy and maneuverability are critical to success.
The F-35A was not designed to be an air superiority fighter, but the pilots interviewed conveyed the picture of a jet that will more than hold its own in that environment—even with its current G and maneuver restrictions. In the words of an F-16C Weapons School Graduate and instructor pilot now flying the F-35A, “Even pre-IOC,[26] this jet has exceeded pilot expectations for dissimilar combat. (It is) G-limited now, but even with that, the pedal turns[27] are incredible and deliver a constant 28 degrees/second. When they open up the CLAW, and remove the (7) G-restrictions, this jet will be eye watering.”[28]

Ociscena tema, a ucesnicima iste predlog da se ne nerviraju ako nesto neko postavi sto im se ne svidja. Izbroj do deset, pa onda odgovori stalozeno bez da eksplodiras. Ako nisi za to sposoban batali forum jer samo se nerviras a nerviras i druge i onda nastane haos.

33 wing je imao "sortie surge" vezbu, kao proveru spremnosti aviona i ekipa, u trajanju od 3 dana. Radili su u smenama po 12 sati. Uspeli su da izvedu 111 poletanja.

Posle deset godina kašnjenja: Ovo je uzdanica avijacije SAD
Citat:Gotovo deset godina nakon prvog leta, višenamenski borbeni avion F-35 lajtning napokon je spreman za borbene misije, saopštile su vazdušne snage SAD-a. Ova odluka vazduhoplovstva snaga stiže godinu dana nakon što su Američki marinci objavili da je njihova eskadrila F-35-ica spremna za borbu.
Ceo program razvoja ovog aviona, započet 2001. godine, do danas je koštao oko 400 milijardi dolara, a procenjuje se da će do kraja svoje službe (oko 2070.) američkim poreskim obveznicima iz džepa izbiti 1.500 milijardi dolara. Bez imalo sumnje reč je o najskupljem vojnom programu u istoriji.

US Air Force Cannot Afford to Buy Enough of Its Own $150mn F-35 Fighter Jets
After spending upwards of $1.5 trillion of US taxpayer money towards corporate welfare for arms producer Lockheed Martin the ensuing damage to the defense budget will cripple the US Air Force’s ability to field a proper fleet of the fifth-generation jets.
The head of Air Combat Command expressed concern with the current F-35 buy rate plan cautioning the need to build up the military branch’s fighter jet inventory at a fast pace in order to prepare for the global security threats of tomorrow, but Air Force civilian chief signaled Wednesday that there is simply not enough money to field the desired fleet of warplanes.
In an interview with Air Force Times, Air Force Secretary Deborah Lee James dashed hopes that the military branch would acquire F-35s at a faster rate than the current plan saying that boosting the number of active-duty airmen is the primary priority at this time.
"It’s all a matter of money. I would love to buy also, but I don’t see that as more urgent than staying the course to increase our end strength," said Secretary James. "Increasing that end strength is the top thing. We think it’s the top thing for all our senior leaders."
Gen. Herbert "Hawk" Carlisle, the Commander of Air Combat Command, disagrees with his civilian counterpart’s assessment telling reporters on Tuesday that he was concerned about the service’s F-35 buy rate which hovers around 40 aircraft per year until fiscal year 2021 when the number jumps up to 60. Carlisle explained that the Air Force must buy at least 60 aircraft per year in the near term to replace defective or obsolete warplanes.
"I need more [F-35s] sooner to replace legacy airplanes and airplanes that are going to require money to do service life extension and do capability increases if I don’t replace them with the F-35," he said. "So I would like to see the numbers go up to at least 60 if I can. 80 would be optimal, but given the fiscal constraints that we’re in today, 80 would be very, very hard to get."
The conservative think tank, The Heritage Foundation, released a report on Thursday siding with Gen. Hawk Carlisle calling for the Air Force to procure its full 1,763-aircraft program of record throughout the life of the program and noting that once full-rate production begins the aircraft’s price tag will lower becoming cost-competitive with similar fighter jets.
"The Air Force is currently deferring the purchase/cashing in on F-35As to pay for other critical needs that have gone unfunded or underfunded by Congress," said John Venable, the senior defense fellow who wrote the report. "That practice needs to end immediately."
Ultimately it appears unlikely that the US Air Force will be in a position to boost its haul of F-35A fighter jets given the exorbitant cost of the project on the front end. As Richard Aboulafia, a defense analyst for the Teal group explained, "You’re left with two choices. You either grow the top-line [budget] – good luck with that – or you take cash away from the bomber, which doesn’t appear to be likely."

Singapurcani jos nisu odlucili
Singapore Puts Off Decision on F-35 Buy
Citat:Singapore has put on hold a decision to buy as many as 12 of Lockheed Martin Corp.’s F-35 jets, according to information from the Pentagon’s program office.
The island nation’s permanent secretary of defense development informed the U.S. in mid-June that it was delaying final steps toward purchasing four of the fighters by about 2022, with an option to buy eight more, according to the information presented to Pentagon officials last month as part of their regular reviews of the costliest weapons program.

У просеку 39 полетања дневно, а колико авиона је учествовало?
На википедији наводе да је 33 винг има најмање 59 Ф-35.
