Posted 10/30/2009 Printable Fact Sheet

The North American F-108 was designed as a very high speed (Mach 3) interceptor and escort fighter for the B-70 "Valkyrie" bomber under development at the same time. The delta wing Rapier, in its pre-mockup phase, was to have a canard (forward-mounted pitch-control surface) and three vertical stabilizers: one on the fuselage centerline and a pair at the halfway point on the wing trailing edge for high speed stabilization at speeds above Mach 2.

The aircraft design was changed during the mockup phase. The canard was removed and the upper portions of the wing-mounted vertical stabilizers were removed. The wing was changed from a standard delta to a double-delta; the winglet incorporated a droop and 45-degree sweep (the main wing had about a 65-degree sweep).

The F-108 program was canceled on Sept. 23, 1959, never getting past the mockup phase.
