Sidewinder to take aim at ground targets

A software tweak will transform the venerable Sidewinder missile, known for its air-to-air precision, into a weapon that can strike rapidly moving targets on the ground.
With three tests already proving that the AIM-9X Sidewinder can zero in on a boat or armored personnel carrier, the next step is to refine the way pilots aim and launch them, said Jeffrey White, AIM-9X program manager at Raytheon Co., which developed the missiles. Those tests begin this year.
Versions of the supersonic Sidewinder have flown on Air Force fighters since the mid-1950s as a missile intended to shoot down aircraft. The Air Force pays about $84,000 apiece for the AIM-9X, the latest Sidewinder variant, but the cost of the additional air-to-ground capability has not been determined.
