Photograph. Northrop XP-56 Black Bullet fighter interceptor parked at air field. Official Caption: “Rome, 6/7/45--New type U.S. pursuit plane--The XP-56, the new pusher type tail-less pursuit plane--first all-magnesium airplane and first all-welded plane ever built--is unveiled at the Northrop plant in Los Angeles, in the U.S. west coast state of California, where it was constructed for the U.S. Army Air Forces. A blower-cooled engine, which drives the twin counter-rotating propellers located behind the nacelle, is completely concealed inside the fuselage. This is the first pusher-type plane to carry counter-rotating propellers. On the wing trailing edge are elevators and lateral control, while fixed vertical fins above and below the fuselage provide directional stability.--PNT photo--Serviced by Rome OWI (A List out).
