The $77 Billion Fighter Jets That Have Never Gone to War

More than five years and nearly $80 billion after the world's most expensive fighter jets joined the U.S. military fleet, the high-tech stealth F-22 Raptor has yet to see combat -- despite the U.S. Air Force's involvement in three simultaneous major combat operations.

When the U.S. led an international effort to secure a no-fly zone over Libya last month, the F-22, the jet the Air Force said "cannot be matched," was not involved. The Air Force said the $143 million-a-pop planes simply weren't necessary to take out Libyan dictator Moammar Gadhafi's air defenses.
