McDonnell's detail design of a strategic penetration fighter intended to escort bombers of the recently established-21 March 1946-Strategic Air Command. The Air Force ordered two prototypes of McDonnell's original Voodoo under the designation XF-88. The first XF-88 flew on 20 October 1948, some 6 months after the contracted delivery date. This initial slippage, the contractor claimed, was the result of changes in the prototype's structural design. The change from straight wing to a 35-degree wing-swept back, along with the danger of compressor stalls at high speed, caused McDonnell engineers to alter the shape of the ducts through which air entered the turbine engines. The second XF-88, with short afterburners boosting the thrust of its J--43-WE-22 engines, did not fly until 2 years later.

A total of 77 F-101As were built. They were gradually withdrawn from service starting in 1966. Twenty-nine survivors were converted to RF-101G specifications with a modified nose, housing reconnaissance cameras in place of cannons and radar. These served with the Air National Guard through 1972.
