HISTORY



Detailing the development and operational history of the Curtiss XP-46 Fighter Aircraft Prototype.  Entry last updated on 6/26/2017. Authored by Staff Writer. Content ©www.MilitaryFactory.com.
The smallish XP-46 was to be the answer for the deficiencies encountered in the P-40 Warhawk platform. Unfortunately for Curtiss, the XP-46 would be doomed by underperformance and sluggish capabilities - essentially dooming the company itself form ever producing fighters for the military.

The XP-46 was to take everything right about the P-40 and make it better. Along the way, the drawbacks of the 1930s-era system would be ironed out. The result was to be a small nimble fighter capable of a dreamed-up speed of over 400 miles per hour and built in the same vein as the successful Bf 109 and the Supermarine Spitfires - a fighter the American forces could call upon to conduct most any type of operation on any front.

With production of the P-40 Warhawk in full swing, designers at Curtiss had sold the idea of a more powerful successor to the US Army Air Corps, to which two prototypes were ordered. The design called for the system to be powered by an Allison brand liquid-cooled engine capable of 1,150 horsepower fitted into a smallish frame. Armament - proposed but never fitted to either prototype - was consist of eight .30 caliber machine guns mounted in the wings with an additional two .50 caliber systems in the nose.

By the time the second prototype had flown as the XP-46A, the system was already showing clear signs of never really matching even the outdated P-40 it was to replace. Looking every bit like the P-40 itself, the XP-46 proved to be slow-responding for a fighter and the 400mph speed was never close to being reached. The samples were later scrapped and the Curtiss company was finished - leaving the P-40 Warhawk as the single symbol of their fighter-designing days of success behind.
