Lockheed YP-24
The Lockheed-Detroit YP-24 was a 1930s prototype two-seat fighter aircraft. An attack version called the A-9 was also proposed. The YP-24 is most remarkable for being the first fighter aircraft to bear the Lockheed name.
==Design and development==
In 1930, Detroit Aircraft Corporation undertook a private venture to develop a new fighter ("pursuit aircraft" in contemporary terminology) for US Army Air Corps based on the successful Lockheed Altair transport plane. Designed by Robert J. Woods, the aircraft was completed in 1931 with Detroit Aircraft fabricating the metal fuselage and Lockheed providing the wooden wings, essentially identical to the Altair. Wright Field assigned the prototype the designation XP-900. Vance Breese was hired to be the chief test pilot for the project. The aircraft was purchased by USAAC in September 1931 and redesignated YP-24, serial number ''32-320''. Early testing was sufficiently impressive to generate an order for five Y1P-24 fighters and four Y1A-9 attack aircraft intended to replace the Berliner-Joyce P-16. The A-9 differed in having four forward-firing machine guns, underwing racks for bombs, and a V-1570-27 engine better low-altitude performance.〔("Fact Sheet: Detroit-Lockheed YP-24." ) ''Museum of the United States Air Force.''
