The Air Force has provided the House a classified report on restarting the F-22 Raptor fighter jet program, congressional staff said Tuesday.

The House Armed Services Committee received the report two days ago, but staff said it was still being reviewed.

House lawmakers ordered the report last year to determine what it would take and how much it might cost to begin producing the high-tech, fifth generation aircraft again.

Congress voted in 2009 to stop purchasing the F-22 stealth fighters after just 187 were made, hundreds less than the Air Force had planned.

Armed Services, under its chairman Rep. Mac Thornberry, has been considering whether the additional aircraft might still be built for the service to fill U.S. air power needs.
