F-35 News: Export JSF less 'stealthy'? Monday, April 19, 2004 - 08:08 PM There are conflicting reports that the export version of the F-35 JSF would have less low-observable (stealth) qualities than the ones to be delivered to the U.S. According to the Jane's website article: JSF security technology costing up to USbn, part of the reason for the budget overrun is wanting to keep certain technology secure. Quote from the article: Up to US$1 billion of the projected cost overrun on the Lockheed Martin F-35 Joint Strike Fighter (JSF) is attributable to the development of 'anti-tamper' (AT) technology to protect stealth features on the JSF, together with a 'sanitized' and probably less stealthy export configuration of the fighter. The clear implication is that the 'international' JSF would have a larger RCS than the US version, would be easier to detect by hostile radars and would consequently be more susceptible to attack."
