Sidney Morning Herald<\/a>, consacr\u00e9 effectivement aux qualit\u00e9s du JSF. L’article est du plus haut int\u00e9r\u00eat et nous engageons nos lecteurs \u00e0 le consulter. Il rapporte des accusations s\u00e9rieuses concernant les capacit\u00e9s du JSF, essentiellement venues d’un parlementaire lib\u00e9ral et ancien analyste de d\u00e9fense, le Dr. Dennis Jensen, docteur en physique appliqu\u00e9e et consultant de la Defence Science and Technology Organisation du minist\u00e8re de la d\u00e9fense. Les pr\u00e9occupations de Jensen sont d\u00e9sormais partag\u00e9es par un autre parlementaire lib\u00e9ral, David Fawcett, anciennement commandant du centre d’\u00e9valuation en vol de la RAAF. Des parlementaires et des clients s\u00e9rieux.<\/p>\n<\/p>\n\tJensen-Fawcett signalent que le JSF co\u00fbtera certainement plus cher qu’annonc\u00e9 ; qu’il a des qualit\u00e9s d’autonomie tr\u00e8s faibles compar\u00e9s au F-111 qu’il doit remplacer, n\u00e9cessitant l’usage de ravitailleurs en vol ; qu’il a des capacit\u00e9s tr\u00e8s faibles en combat a\u00e9rien, qui le placent dans des conditions d’inf\u00e9riorit\u00e9 manifeste \u00e0 l’encontre des chasseurs Sukho\u00ef (29 et 35) en service dans la zone. Jensen d\u00e9finit le JSF au combat comme un camion \u00e0 bombes (\u00ab essentially a second tier bomb truck. It lacks the necessary aerodynamics to defeat the<\/em> [Sukhoi] Flankers, never mind future aircraft that may proliferate<\/em> \u00bb).<\/p>\n<\/p>\n\tEnfin, il y a le probl\u00e8me de sa furtivit\u00e9 (stealth<\/em>), qui s’av\u00e8re inf\u00e9rieure \u00e0 ce que les Am\u00e9ricains annon\u00e7aient. C’est une tr\u00e8s mauvaise nouvelle pour le JSF dont les caract\u00e8res affirm\u00e9s de machine technologiquemnt tr\u00e8s avanc\u00e9e reposent en bonne partie sur la r\u00e9putation d’une capacit\u00e9 furtive exceptionnelle.<\/p>\n<\/p>\n\tJensen, qui signale que le JSF est tr\u00e8s vuln\u00e9rable \u00e0 la d\u00e9tection par l’arri\u00e8re, rapporte que le Pentagone a lui-m\u00eame r\u00e9cemment d\u00e9grad\u00e9 sa pr\u00e9sentation officielle des capacit\u00e9s de furtivit\u00e9 du JSF. L’avion est d\u00e9sormais qualifi\u00e9 de low observable<\/em> alors qu’il \u00e9tait auparavant very low observable<\/em> (\u00ab Peter Goon, a former RAAF flight test engineer, said that would mean the difference between it appearing as a marble and a beach ball on enemy radar.<\/em> \u00bb).<\/p>\n<\/p>\n\tLe r\u00e9cit des d\u00e9marches qu’il a fallu effectuer pour obtenir confirmation de cette d\u00e9gradation des capacit\u00e9s furtives du JSF indique, par le simple constat des manuvres d’emp\u00eachement d\u00e9velopp\u00e9es \u00e0 l’encontre les g\u00eaneurs, 1) que l’affaire est s\u00e9rieuse et 2) qu’elle est r\u00e9cente et r\u00e9sulte des constats effectu\u00e9s lors d’essais en vol. \u00ab A Federal Government source conceded yesterday that the stealth capability definitions had been changed, but maintained that the design requirements for the fighter to avoid detection had not.<\/em><\/p>\n<\/p>\n\t\u00bb Signs that the stealth capability had been lowered first emerged last year, when key performance indicators on the US Defence Department Joint Strike Fighter website changed. The manufacturer of the aircraft, Lockheed Martin, insisted repeatedly to the Herald that the reported shift was an error. Australia’s Defence Department also maintained there had been no change.<\/em><\/p>\n<\/p>\n\t\u00bb But those assurances have proven false. When the Herald contacted the US Defence Department Joint Strike Fighter program office in Washington, a spokeswoman said the latest table on its website was correct. There is no reason to pull it from there, she said.<\/em><\/p>\n<\/p>\n\t\u00bb A Lockheed Martin spokesman said yesterday: We will have to defer to our clients, the US Government, if that is their decision.<\/em> \u00bb<\/p>\n<\/p>\n<\/p>\n
