F-22 production line is closed and no further aircraft will be produced. The F-22 program was canceled in July 2009, with production standing at 187 aircraft.
Unit cost was variously reported at between $150million to $361million - just a little short of the $1-2billion alluded to above...
Seems likely this is a sad loss - at time of writing no sign of aircraft or pilot and suggestions from the Pentagon that the aircraft was lost in the Alaskan wilderness.
