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.[1] 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. The 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.
Design and development
[edit]The aircraft started life as a project for an attack aircraft, designated XA-43. When the United States Army Air Forces issued a requirement for a jet-powered all-weather fighter in 1945, the design was reworked for that request.
The XP-87 was a large mid-wing aircraft with four engines paired in underwing pods, with a mid-mounted tailplane and tricycle undercarriage. Two crew members (pilot and radar operator) sat side by side under a single canopy. Armament was to be a nose-mounted, powered turret containing four 20 mm (0.79 in) cannon, but this was never fitted to the prototypes. Instead the aircraft was armed with four fixed forward firing 20mm cannon.[2]
Operational history
[edit]The first flight of the XF-87 Blackhawk was on 5 March 1948.[3] 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 canceled on 10 October 1948, and both prototypes were scrapped.
