Citação de: "JMM"
Infelizmente não me parece... continua a ser carote fazer a modernização e vai ser demasiado tentador englobar os aviões nas contrapartidas para as Lajes, por isso meu caro, lamento, mas quase de certeza que vai continuar a  ser material "made in Tio Sam"!


Por falar nas Lajes gostava de saber uma coisa, alguém sabe que género de benefícios tem o Reino Unido, Alemanha, Itália e outros paises por permitir que os Estados Unidos tenham unidades militares nos seus países?

Ou a Alemanha e a Itália tem que estar "ocupadas" por forças militares Americanas pelo que fizeram na 2ª Guerra Mundial?

 Espero que esteja redondamente enganado.

Porquê?
Ou é só para contrariar?


 EU disse é que espero que eu esteja redondamente enganado, porque se eu estiver enganado, é porque vamos ter F35 novos. Expliquei-me mal.

“Eurofighter Slays’Em!

I remember reading around two years ago about the prowess of Eurofighter over other aircraft. Well, this anecdote will probably ‘get out’ one day and concerns the visit to these shores in July of Indian Air Force Su-30s. The MoD said that it would not be putting Typhoons up against them as a one-on-one fight. This is general knowledge. However - it did happen and there is Head Up Display video to prove it. I don’t know how it came about - probably during some exercise.

Anyway, two relatively inexperienced Typhoon pilots returned with big grins on their faces. The Sukhois were ‘toasted’. All the Su-30’s air display antics came to nought - the Typhoons proved too nimble and too powerful for the Russian aircraft. The Typhoons were not ‘clean’ either. You can check with the MoD, but you probably already know the kind of answer you’ll get! (We did, and they wouldn’t - Editor).

The original article resulted in several letters of response about Typhoon versus the F-22. This cannot be confirmed or admitted officially, but during Typhoon’s visit to the USA in 2005, both aircraft were pitted against each other (unofficially, you understand). The F-22 could not be seen by the Typhoon pilot, but his electronic counter measures showed him that it was being ‘painted’ by his opponent. The Typhoon took appropriate ‘measures’ using self-defensive aids. But when it came to one-on-one combat, the Typhoon did the same kind of job as it did with the Sukhois. The F-22s could not ‘handle’ Typhoon close in and the Yanks were shocked!

It did not all go Typhoon’s way on this occasion but it was a sobering encounter for the Americans. Remember, on the F-22 much was sacrificed in terms of ‘fighter performance’ for stealth.

The first part of this letter, regarding the Sukhois, I have from first-hand experience, through the second part - about the F-22s - has come to me through the Typhoon grapevine. Fascinating, isn’t it? The Typhoon does appear to be a truly formidable machine - a machine feared by ‘other’ operators.

Through still a relatively immature platform, Typhoon has already proved to be a hard opponent to beat, so that when a two-seat trainer was bounced by two F-15s during an operational conversion sortie, the Typhoon pilot was easily able to outmanoeuvre his assailants and position himself for a simulated ‘kill’ against both. More recently, there have been repeated reports that two RAF Typhoons deployed to the US for OEU trials work have been flying against the F-22 at NAS China Lake, and have performed better than was expected. There was little surprise that Typhoon, with its world-class agility and high off-boresight missile capability was able to dominate the ‘Within Visual Range’ fight, but the aircraft did cause a surprise by getting a radar lock on the F-22 at a surprisingly long range. The F-22s reportedly cried off, claiming that they were ‘unstealthed’ anyway, although the next day’s scheduled two versus two BVR engagement was cancelled, and “the USAF decided that they didn’t want to play anymore”. When this incident was reported on a website frequented by front-line RAF aircrew a senior RAF officer urged an end to the conversation on security grounds.

F-35 Joint Strike Fighter: Events & Contracts 2007-08 (updated)

The F-35 Lightning II is a major multinational program which is intended to produce an “affordably stealthy” multi-role strike fighter that will have three variants: the F-35A conventional version for the US Air Force et. al.; the F-35B Short Take-Off, Vertical Landing for the US Marines, British Royal Navy, et. al.; and the F-35C conventional carrier-launched version for the US Navy. The aircraft is named after Lockheed’s famous WW2 P-38 Lightning, and the Mach 2, stacked-engine English Electric (now BAE) Lightning jet. System development partners included The USA & Britain (Tier 1), Italy and the Netherlands (Tier 2), and Australia, Canada, Denmark, Norway and Turkey (Tier 3). Now the challenge is agreeing on production phase membership and arrangements, to be followed by initial purchase commitments around 2008-2009.

This updated article has expanded to feature more detail regarding the $300 billion F-35 program, including other contracts as well as notable events. New material is in green type. Recent additions include background re: the F-35’s initial armaments, a DSCA request from Israel for up to 75 F-35s, Italy opting out of the test phase, an Italian capabilities and industrial evaluation, Tier 2 JSF partner The Netherlands’ slip toward a full competition involving Sweden’s Gripen fighter, a number of firm engine and software contracts, big Canadian investments in Texas, and a major controversy in Australia over the plane’s air-air performance…

Work involving low-observable (LO) coating is currently the only time-consuming maintenance procedure. Getting to a failed fuel pump on non-stealth aircraft is relatively easy. By comparison, the F-22 must be de-skinned before the pump can be removed, and a replacement fitted. After that, the LO coating has to be restored – a process that typically takes 12-18 hours to complete.

Seventy people in the 1st MXG are assigned to LO, inspecting the aircraft every day for surface cracks, bonding or anything that may detract from its stealthy characteristics. These are tracked in the IMIS (Integrated Maintenance Information System) and given a serviceability rate. “We watch the aircraft rate and if its level is close to the limit, then we ground the aircraft on a SAS (Signature Assessment System) reduction to restore the stealthiness of the aircraft back to specification,” said Chief Wilder.

Cracked coatings are removed and replaced with new ones to reduce the serviceability rate to an acceptable level. If LO coatings are not managed correctly, the aircraft is no longer stealthy, and this could put a pilot in harm’s way.

Há um velho ditado muito utilizado no mundo da aviação que diz, “if it looks right, it flies right”. Pessoalmente não o aplicaria ao F-35. Não gosto do avião! :evil:

F-35 Has A Fatal Flaw

October 29, 2008: While the new American F-35 fighter-bomber is superior in many ways to the aircraft it is replacing (F-16s and F-15s). But in one area it is inferior, and this may turn into  major political and legal problems.

The F-35 is twice as loud on takeoff, and even louder when landing. Civilians living around F-35 bases will complain, as that much additional noise will be noticed when the new aircraft replace F-15s and F-16s over the next decade. There will be lawsuits, and headaches  for air force commanders. There might even be bans and groundings.

cada dia que passa o f35 aparece com mais problemas, primeiro é o preço do projecto que aumenta a cada dia que passa, depois é a capacidade de ser invisível ao radar que segundo li os americas não querem que os europeus usem a versão stealth e agora é o barulho. Cada dia que passa gosto menos deste avião, será que Portugal faz bem continuar com a intensão de adquirir este avião :?:
pessoalmente acho que não
