    Staff Writer (Updated: 12/28/2016): The arrival of the high-flying, long-range Boeing B-29 "Superfortress" strategic bomber in May of 1944 led United States Army officials to consider a long-range fighter escort to protect their expensive, technology-laden investment. Northrop managed to introduce their impressive P-61 "Black Widow" that same year and this marked the first purpose-built American night fighter. Engineers were convinced of the merits of the large fighter as a long-range bomber escort and the company championed the idea to Army officials. Enough interest was had in the endeavor to result in the "XP-61E", a modified version of the successful night fighter.

    A pair of P-61B-10 aircraft were set aside for conversion to the long-range, high-altitude bomber escort role. The dorsal turret was removed and the upper fuselage cut down to produce a slimmer, lighter and more aerodynamically refined form. No longer requiring radar (the fighter would be a daytime operator), the nose assembly was cleared of the radar fit and in its place a battery of 4 x 0.50 caliber Browning heavy machine guns installed (the ventral battery of 4 x 20mm cannons seen in the original P-61 fighter was retained). As no radar was carried, the radar operator crewman was expendable which led to a reduction of total crew to two and these personnel were now seated in tandem under a shared bubble-style canopy. More internal fuel stores were added to help increase the aircraft's range - a requirement for the long-range bomber escort role.

    The result was a powerful, reasonably fast and well-ranged performer with sleek contours and a promising future. The aircraft held a wingspan of 66 feet with a length of 49.6 feet and height of 13.4 feet. Empty weight was 21,350lb against a laded weight of 40,181lb. Power was from 2 x Pratt & Whitney R-2800-65 radial piston engines of 2,000 horsepower each propelling the aircraft to speeds of 376 miles per hour. Rate-of-climb was 2,500 feet-per-minute with a service ceiling of 30,000 feet and range out to 2,250 miles. ©www.MilitaryFactory.com
