McDonnell Aircraft grew from James S. McDonnell's prewar St. Louis company into one of the United States' leading jet-fighter producers. Boeing's heritage material says McDonnell incorporated the company in St. Louis on July 6, 1939, and that within three decades it had become a leading producer of jet fighters and had built the first spacecraft to carry an American into orbit.
For defense-aircraft records, the McDonnell name is most closely tied to Cold War fighter and interceptor families. The National Museum of the United States Air Force describes the F-101 Voodoo as an XF-88-derived aircraft first intended as a Strategic Air Command bomber escort before shifting into tactical and air-defense roles, with 785 Voodoos built by McDonnell by March 1961. The same museum describes the Phantom II as a Navy fleet-defense fighter first flown in May 1958, later produced in more than 5,000 examples for U.S. and allied services.
McDonnell Aircraft ended as a standalone company through the 1967 combination with Douglas Aircraft Company. Boeing's executive-history material places McDonnell Aircraft Corp. in the 1939-to-1967 company-history period and describes the 1967 merger with Douglas Aircraft as the expansion that created McDonnell Douglas, the successor corporation later acquired by Boeing.

McDonnell Aircraft Corporation existed as a standalone manufacturer from 1939 until the 1967 McDonnell Douglas merger. Later sources often use McDonnell Douglas for F-4 and successor-program context, so this profile separates pre-merger McDonnell Aircraft attribution from later McDonnell Douglas records.
