A Curtiss-Wright XP-55 Növekvő (cég megnevezése CW-24) egy 1940-es években az Egyesült Államok prototípus vadászgép által épített Curtiss-Wright. A Vultee XP-54 és a Northrop XP-56 mellett az Egyesült Államok Hadseregének R-40C javaslatát is kiadták, amelyet 1939. kifejezetten lehetővé tette a nem hagyományos légijármű-terveket. Egy nagyon szokatlan design a maga ideje, volt egy canard konfiguráció, a hátsó szerelt motor, söpört szárnyak, és két függőleges farok. A tológép kialakítása miatt szarkasztikusan "Ass-ender"-nek nevezik. Az XP-54-hez hasonló ascendert eredetileg a Pratt & Whitney X-1800-as motorhoz tervezték, és újra kellett tervezni, amikor a motorprojektet törölték. Ez volt az első Curtiss vadászgép, amely tricikli futóművet használt.

General Characteristics and Role
The Curtiss XP-55 Ascender (Curtiss-Sperry Model 24) was an experimental fighter prototype developed for the U.S. Army Air Forces (USAAF) during World War II. It was the product of the 1940 “R-40C” proposal for unconventional aircraft designs, alongside the Northrop XP-56 Black Bullet and Vultee XP-54 Swoose Goose. The Ascender featured a highly radical and futuristic design for its time: a tailless canard configuration with the engine mounted at the rear, driving a pusher propeller. This layout was intended to improve aerodynamics and provide an unobstructed forward field of fire. Despite the design’s potential, the XP-55 suffered from stability issues, poor low-speed performance, and did not live up to performance expectations, leading to its cancellation after three prototypes were built.

Powerplant and Design
- Engine: One Allison V-1710-95 (F23R) liquid-cooled V12 engine.
- Power Output: 954 kW (1,275 hp).
- Propulsion: 3-bladed propeller in a pusher configuration (at the rear).
- Maximum Speed: 628 km/h (390 mph; 339 kn) at 5,800 m (19,000 ft).
- Range: 1,040 km (650 mi; 560 nmi).
- Design Layout: Canard (small horizontal surface in the nose) and a mid-set wing with twin tail booms supporting the rudders. The main wings were swept back slightly.
- Pilot Safety: Due to the rear-mounted propeller, the pilot was equipped with a system to jettison the propeller assembly before bailing out in an emergency.
Armament (Intended) and Service
- Intended Armament: 2 x 20 mm cannon and 2 x .50 in (12.7 mm) machine guns, all mounted in the nose. (Prototypes often flew with reduced or no armament).
- Service History: The first prototype crashed due to a stall/spin in a test flight. Despite modifications to the second and third prototypes, they were ultimately outclassed by conventional and early jet fighters.
- Legacy: The XP-55’s radical configuration helped advance research into canard aerodynamics, a concept later successfully used in aircraft like the Saab Viggen and Eurofighter Typhoon.
