McDonnell XF-88 Voodoo
aircraft
The McDonnell XF-88 Voodoo was a long-range, twinjet fighter aircraft designed for the United States Air Force. Although it never entered production, its design was adapted for the subsequent supersonic F-101 Voodoo.
Design and development
The XF-88 originated from a 1946 United States Army Air Forces requirement for a long-range "penetration fighter" to escort bombers to their targets. It was to be essentially a jet-powered replacement for the wartime North American P-51 Mustang that had escorted Boeing B-17 Flying Fortress bombers over Germany. It was to have a combat radius of 900 mi (1,450 km) and high performance. McDonnell began work on the aircraft, dubbed Model 36, on 1 April 1946. On 20 June the company was given a contract for two prototypes designated XP-88. Dave Lewis was Chief of Aerodynamics on this project.
The initial design was intended to have straight wings and a V-shaped tail, but wind tunnel tests indicated aerodynamic problems that led to a conventional tailplane being substituted and the wings being swept. The USAAF confirmed the order for the two prototypes on 14 February 1947, while a change in designation schemes led to the unflown prototypes being re-designated XF-88 on 1 July 1948, with the type gaining the nickname "Voodoo".

Why this record matters
The phrase “aircraft” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 26, 2025. The linked authority identifier is Q1957732. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1946, 1947 and 1948.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
