The Curtiss XA-14 was a 1930s United States airplane, the first multi-engine attack aircraft tested by the United States Army Air Corps. Carrying a crew of two, it was as fast as the standard pursuit aircraft in service at the time. Design and developmentOriginally built as an in-house venture as the Curtiss Model 76, powered by two experimental Wright XR-1510 radial engines, flight testing was sufficiently impressive that after the USAAC appraisal the Model 76 was returned to Curtiss and fitted with two 775 hp (578 kW) Wright R-1670-5 Cyclone engines with constant-speed propellers. This configuration was accepted by the Army with the designation XA-14.[2] It had standard Army markings with the serial number 36-146.[3] The Model 76 was of all-metal construction with an oval section semimonocoque fuselage, described as "pencil slim". The XA-14 was extensively tested, at one stage being fitted with a 37 mm (1.46 in) nose cannon.[4] In July 1936, 13 developed versions, re-engined with two Wright R-1820-47 Cyclone twin-row radials, were ordered into production as the Y1A-18.[3] Specifications (XA-14){{aircraft specifications|plane or copter?=plane |jet or prop?=prop |ref=USAF Museum |crew= two |capacity= |payload main= |payload alt= |payload more= |length main= 40 ft 3 in |length alt= 12.3 m |span main= 59 ft 5 in |span alt= 18.11 m |height main= 10 ft 9 in |height alt= 3.3 m |area main= |area alt= |airfoil= |empty weight main= |empty weight alt= |loaded weight main= |loaded weight alt= |useful load main= |useful load alt= |max takeoff weight main= 11,750 lb |max takeoff weight alt= 5,330 kg |more general= |engine (jet)= |type of jet= |number of jets= |thrust main= |thrust alt= |thrust original= |afterburning thrust main= |afterburning thrust alt= |engine (prop)= Wright R-1670-5 |type of prop= radials |number of props= 2 |power main= 775 hp |power alt= 578 kW |power original= |max speed main= 254 mph |max speed alt= 221 kn, 409 km/h |cruise speed main= |cruise speed alt= |never exceed speed main= |never exceed speed alt= |stall speed main= |stall speed alt= |range main= 825 mi |range alt= 717 nmi, 1,328 km |ceiling main= 27,100 ft |ceiling alt= 8,260 m |climb rate main= |climb rate alt= |loading main= |loading alt= |thrust/weight= |power/mass main= |power/mass alt= |more performance= |armament=
