F-22 Raptor

Rappel du premier message :

Dans ce qui suit, des extrait d'un certain nombre d'article sur le web parlant de cette terreur volant, je vous laisse admirer d'abord le charme de cette bête de combat.

tu sais docteur chacun a le droit de supposer ce qu'il veut, ça fait avancer le débat. j'ai même vu un sondage sur un forum français où le RAFALE était mieux noté que tous les chasseurs moderne y compris F-22, F-35, Typhoon...
mais en réalité le F-22 constitue un pas géant dans la technologie de l'aviation militaire et marque une époque nouvelle que bcp de pays peinent encore à atteindre. la preuve, bcp de pays cherchent à se rattraper par rapport au raptor comme la russie à travers son prjet PAK FA, le F-22 quant à lui existe déjà depuis une decennie et il est entrain de d'évoluer encore et encore, blk 30 bientot et blk 40 dans une decennie.

il confond la France et l´USA?

il croit vraiment que les US lesigneront sur les moyens pour avoir leur jets au bout du compte?
c´est pas la france qui ne peut pas financer correctement ses programmes d´armement comme le Rafale ou FREMM comme voulu au debut!

si le Rafale etait US il aurait ete fini maximum en 2000 et vendu a plusieurs pays deja,mais les moyens varient avec la puissance des pays...au lieu de voir ailleurs et "esperer" la chute des US il ferait mieux de voir ce qui na va pas at home

C'est clair !
des pays capables de mettre 300 milliards $ sur un seul un programme en y a pas bcp ds le monde ....

Raptor a raison de dire quand certain cherhe encore à mettre au point leur appareil de 5ème géné., les ricain en sont déjà à monté leur escadrille avec.

Si les russes cherchent une collaborations avec l'inde pour le programme PAK-FA, c'est uniquement pour obtenir des crédits supplémentaires (la participation de new delhi sur le plan technique sera minime), il ne fait aucun doute les US ont génération d'avance je vois pas actuellement est mesure de les rattraper....

Par contre je doute vraiment que l'on peut remettre en cause la suprématie américaine actuellement qui ajd'hui en est mesure de faire face à ça !

F-22 Raptor To Make Paris Air Show Debut

Feb 4, 2009
By David A. Fulghum


The U.S. Air Force is taking the F-22 Raptor to the Paris Air Show for the first time this summer, according to Larry Lawson, executive vice president and general manager of the F-22 program.

The trip to Paris has been long delayed. A furor that surrounded the detailed customs inspection and electronic surveillance of the F-117 the only time it went to France has apparently subsided.

The new U.S. administration has no grudge against France for not participating in the invasion of Iraq. Even recent concerns about the French air force’s electronic surveillance of the Indian Air Force’s Su-30 MKI during a 2008 Red Flag exercise at Nellis Air Force Base, Nev., has died down (Aerospace DAILY, Aug. 25). Moreover, the potential for additional U.S. sales and, possibly, foreign sales has removed any remaining barriers.

To pique consumer interest, Lockheed Martin has revealed better than expected performance for the stealth fighter.

The F-22s overperformance includes a radar cross section that is “better” than was contracted for, the company says. That classified requirement has been calculated at a -40 dBsm, about the size of a steel marble. By contrast, the F-35 is thought to be a -30 dBsm, the size of a golf ball. Supercruise is at Mach 1.78 rather than Mach 1.5. And acceleration – although company officials would not say from what speed or at what altitude – is 3.05 seconds quicker than the requirement of 54 seconds.

In nonafterburning military power the Raptor can operate at just more than 50,000 feet. However, it is known that the F-22 opened its aerial battles at about 65,000 feet during its first joint exercise in Alaska, apparently using afterburner.

There also is a mysterious admission that the range of the Raptor’s Northrop-Grumman/Raytheon active electronically-scanned array (AESA) radar is 5 percent greater than expected. That means a cushion of an additional 5-6 miles of detection range against enemy aircraft and missiles.

F-22 Secrets Revealed

February 12, 2009: The U.S. Air Force has released some performance data on the F-22. The stealthiness factor of the F-22 has turned out to be better than predicted. For radar purposes, the F-22 is about the size of a steel marble. The F-35 comes out as a steel golf ball. The AESA radar turned out to have a longer effective range of about 210 kilometers, versus a 200 on the official spec sheet. The AESA radar is also able to detect enemy radars at a considerable distance, meaning that, if an approaching enemy aircraft is using its radar, an F-22 can detect it about 300 kilometers distant. That gives the F-22 more time to get into position for a decisive first shot at the enemy aircraft.
These goodies are being released as the air force makes a pitch to delay some F-35 production in order to build more F-22s. The air force generals point out that the first 500 or so F-35s will cost $200 million each (without taking R&D into account), while F-22s only cost $145 million each (without taking R&D into account). The construction cost of the F-35 will eventually go to about $100 million each as more are produced.

The air force also points out that their simulations (which are classified, so it's difficult for anyone check their accuracy) indicate the an F-22 would destroy 30 Su-27/MiG-29 type aircraft for getting destroyed. But the F-35 would only have a 3:1 ratio, while the F-15 and F-16 would only have a 1:1 ratio (there are a lot of F-15 and F-16 pilots who would dispute this). Thus the need for more F-22s, even if it means fewer F-35s (in the near and long term).

The air force also points out that, with a force of 183 F-22s (all Congress will allow them to build at the moment), only about a hundred would be available for combat (the rest would be down for maintenance or used for training.) By building another 60-100 F-22s, and reducing initial F-35 production by that much, American air superiority would be much improved, at no (well, not much) additional expense. Or so goes the pitch.

Raptor vs JSF
ils vont lacher les clients qui attendent leur JSF pour avoir le Raptor.
que l´USAF lache les specs du Raptor,ca veut tout dire,le matche promet..

S'il commence à critiquer ouvertement les perf du JSF, ça sent pas bond du tout ....
mais ils peuvent les lacher comme ça, avec tout les milliards déjà donné par les autres, ça risque d'être tendu après !

Par contre 300 km pour détecter les ondes radar adverse je pensais pas qu'il pouvait les repéré d'aussi loin ...

ils ont pas le choix. si vous étiez obligés de faire un choix entre raptor et jsf c'est sûr que vous allez choisir le raptor pour deux raison:
il est déjà opérationnel tant bien que mal.
c'est une bête de combat aérien, seul appareil dans l'arsenal américain capable de répondre aux nouveaux défi des nouveaux appareils de 4,5 génération. le jsf n'est pas un chasseur pure, et même en A/S il est pénalisé par une faible capacité d'emport s'il veut vraiment préserver sa furtivité.

Et surtout avec le Raptor pas contrainte avec des partenaires car 100% made in US !

oui, le shéma est simple:
construire de appreils de 5ème génération, l'un poussé à l'extrème dans sa technologie et ses perf. l'autre une copie minature moins performant et plus polyvalent pour partager avec ''les alliés'' et servir pour toutes sorte de mission. et au passage étouffer l'industrie d'aviation militaire européenne.
mais quand il y a crise, premier reflexe: sauver notre bébé en sacrifiant le bébé des autres

C'est Raptor qui va le plus apprécier cette info

Le congrès américain favorable à la poursuite de la production de l'avion de combat F-22…
Le ministère japonais de la Défense attend la décision prochaine du gouvernement américain de produire ou non l'avion de combat F-22, qui est le candidat de choix pour remplacer les F-4 actuellement utilisés par les Forces japonaises d'autodéfense. Le F-22 est un appareil furtif ultrasophistiqué ayant notamment la capacité d'éviter la détection radar. Le ministère espère que l'administration Obama rendra d'ici le 1er mars, son verdict définitif sur le sujet. Le gouvernement Bush avait annoncé son intention d'interrompre la production de cet avion car son coût de mise au point était trop élevé. Le congrès américain avait également interdit la vente à l'étranger du F-22, pour protéger les secrets militaires de ses concepteurs. Mais certains membres du congrès américain ont envoyé une lettre au président Barack Obama, ils réclament la poursuite de la production. Ils citent les capacités militaires de cet avion, ainsi que l'impact économique de la poursuite de la production, qui constitue un bassin d'emplois. Le ministère japonais observe de près l'orientation que prendra l'administration Obama, car il devra éventuellement considérer l'achat d'un autre appareil si la production du F-22 est interrompue.

Merci Samyadams

le F/A-22 est un avion qui a été conçu pour reigner pendant des decennies dans les cieux. c'est un projet certes très coûteux mais viable, et les perf justifient largement le coût.

BREAKING: 60 More F-22s for the USAF

The Air Force’s chief of staff was careful to withhold his professional military advice until Defense Secretary Robert Gates gets it, but Gen. Norton Schwartz told reporters this morning that he would not “dispute” comments by the chairman of the Joint Chiefs late last year that the service would get an additional 60 F-22s, for a total of 243.

Schwartz then poured cold water on any hopes the Japanese and Australians might have of buying F-22s, saying some of the technologies in the plane are just too sensitive to export. However, he said “it was a possibility” that allies could pay for planes that were modified extensively enough to eliminate the export concerns. Given how expensive that would be, Schwartz has probably put the kibosh on export sales.

The Air Force chief of staff defended the decision to scale back the long sacred Air Force requirement of 381 F-22s, saying the service had performed honest and objective analysis to determine the new number of planes. “I’ll be happy to defend the numbers once they become available,” he told us, adding that the new fleet size offers “moderate risk” to the nation.

Of course, this doesn’t necessarily mean that 60 is the exact number everyone has decided on, but Schwartz didn’t try to pour cold water on it either… He did say the final decision should be out very close to the congressionally mandated date of March 1.

Asked about John Young’s comments last November that the F-22’s mission capable rate was too low and expected enhancements too expensive for the country to afford, Schwartz said “the truth of the matter is” the F-22’s rate is 60 percent including stealth issues and is “in the mid- to high-70s without low observable” issues. Looking at the system overall, the F-22’s reliability “is respectable,” he said.

Air Force gives Pentagon new F-22 purchase plan

Friday February 27th, 2009 / 2h19

By Jim Wolf

ORLANDO, Florida (Reuters) - The U.S. Air Force's top general said Thursday he had put forward a fresh request for top-of-the-line F-22 fighter jets that would postpone an otherwise-imminent start to shutting down Lockheed Martin Corp's production line.

Air Force Chief of Staff Gen. Norton Schwartz told reporters he had presented the revised plan to Defense Secretary Robert Gates this week. He declined to elaborate on their discussion.

"Until he renders a decision (on the fate of the F-22), I'd prefer to keep the content of that conversation between the (Air Force) secretary and myself and Secretary Gates," he told reporters after speaking to an Air Force Association symposium in Orlando, Florida.

Lockheed Martin has said it plans to start shutting down the F-22 production line as early as next week unless President Barack Obama decides to buy more than the 183 aircraft now budgeted for.

Schwartz said February 18 that the Air Force had scaled back its previous goal of acquiring a total of 381 F-22s. He said he would not differ with Admiral Michael Mullen, chairman of the Joint Chiefs of Staff, who had said earlier the Air Force was seeking 60 more, or a total of about 243.

Asked about the size of the fleet the Air Force is now seeking, Schwartz said Thursday: "We ran the numbers, validated the assumptions, and came to the conclusion that we did."

The radar-evading F-22 Raptor is the most advanced fighter in the U.S. arsenal, most recently costing about $143 million apiece, not including development.

It has become the focus of a debate about hedging for large-scale wars versus fighting guerrillas in places such as Iraq and Afghanistan, and a lightning rod among arms programs in the deteriorating U.S. economy.

Pentagon press secretary Geoff Morrell said this week that the administration would make its wishes known for the F-22 when it releases full details of the fiscal 2010 budget, likely in April.

In the meantime, the Pentagon planned to notify Congress on or about March 1 of its latest thinking on $90 million in congressionally provided bridge funds for the F-22 that the Pentagon has not yet spent.

"Whatever we decide to do by March 1 with regard to long-lead parts is not necessarily an indication of where we're going with the program as a whole," Morrell said.

The F-22 has strong bipartisan support in the U.S. Congress, not least because of the jobs it provides, with suppliers strategically chosen around the country. Even if the administration opts to end the program, many lawmakers are likely to fight for continued funding.

Congress provided a total of $140 million in bridge funds to keep the F-22's production line going until at least March 1, of which $50 million has so far been spent to keep options for the aircraft intact.

Sam Grizzle, a Lockheed spokesman, said earlier this month that some F-22 suppliers already had been notified that "we willbegin shutdown activities on 1 March unless the President certifies that continued production of the F-22 is in the national interest."

"If the decision on extending F-22 production is not made by March 1, additional funds, already authorized and appropriated by Congress, will be necessary to keep the line open," Grizzle added this week in response to the Pentagon's plans to put off a decision until the 2010 budget is released.

un Raptor killed par le Growler

ce n'est pas le premier kill, le premier appreil à le faire était le bon vieux F-15C dans des exercice en alaska. mais seulement 2 kills contre (de mémoire) 142 kills pour le f-22 face à des F-15 et F-16 de l'usaf.

Raptor, Il ya eu un Ace de F-16 qui a eu un Raptor (pas toi ).
Yak, t'es tres Growler a ce que je vois
