Curtiss XP-87 Blackhawk

The Curtiss-Wright XF-87 Blackhawk (previously designated the XP-87) was a prototype American all-weather jet fighter interceptor and the company's last aircraft project. Designed as a replacement for the World War II–era propeller-driven P-61 Black Widow night/interceptor aircraft, the XF-87 lost in government procurement competition to the Northrop F-89 Scorpion. T

The first flight of the XF-87 Blackhawk was on 5 March 1948. Although the top speed was slower than expected, the aircraft was otherwise acceptable, and the newly formed (in September 1947) United States Air Force placed orders for 57 F-87A fighters and 30 RF-87A reconnaissance aircraft just over a month later. Since the performance problems were due to lack of power, the four Westinghouse XJ34-WE-7 turbojets of the prototypes were to be substituted for two General Electric J47 jets in production models. One of the two XF-87 prototypes was to be modified as a test bed for the new engines.

At this point, the USAF decided that the Northrop F-89 Scorpion was a more promising aircraft. The F-87 contract was cancelled on 10 October 1948, and both prototypes were scrapped. he loss of the contract was fatal to the company; the Curtiss-Wright Corporation closed down its aviation division, selling its assets to North American Aviation.
