Up to US$ 1 Billion of the projected overrun on the Lockheed Martin F-35 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 configulation of the fighter.

Some of this overrun is reflected in a supplemental contract awarded to Lockheed Martin
in November 2003, valued at US$603 million and covering the development of an international
partner version of the JSF. Building export JSFs with less sensitive -and less effective - low
observable (LO) features is practicable because the primary structure of the JSF is
conventional, with most of the LO system being added at the end of the assembly line.

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. Like other LO aircraft,
it does not carry active jamming equipment or a towed decoy and it cannot use high off-bore
sight air-to-air missile when in stealth mode
