The Missile Defense Agency’s Airborne Laser Test Bed (ALTB) is dead after a long battle with Pentagon budgetary priorities and Congress.

But even ALTB couldn’t survive last week’s federal budget slashing. ALTB was sixteen years and several billion dollars old. It will be laid to rest at the the Air Force’s Maintenance and Regeneration Group, known as “The Boneyard.” It is survived by the Navy’s Free Electron Laser.
