처음보는 폭격기인데 제원이 없어서 걍~ 원문을 그대로 발췌합니다 ^^
The first American jet bomber was a straightforward derivative of the radical XB-42 Mixmaster, a twin-piston engine pusher aircraft of Learfan configuration that was supposed to do the job of the B-29 at about half the cost by achieving a 30 percent improvement in aerodynamic cleanliness. The jet age caught up with the XB-42, and Douglas responded by working the static test article into the XB-43 by substituting two GE J35 engines for the piston Allison V-1710s. The airplane was satisfactory, with a 51 5-mph top speed, not bad for a static article, but the B-45 was in the wings. The XB-43 subsequently became an engine test bed at Edwards, earning the nickname Versatile.
With an initial flight date of May 17, 1946, the Douglas XB-43 has the distinction of being the first jet-powered bomber to fly in the United States. The XB-43 served as a useful test bed for several years but offered insufficient capability to warrant production. Prototypes of five, more capable, higher performance jet bombers were flown in 1947; two of these, the North American B-45 and the Boeing B-47, were selected for production.
