Martin XB-51

The XB-51 project originated in an Army Air Forces design competition in February 1946. After disappointing results with the
"conventional" design of the XB-48, Martin produced a strikingly innovative airplane in the XB-51. Two prototype XB-51's were
first flown and tested in late 1949 and early 1950, just before the outbreak of war in Korea. The XB-51 had a crew of only two:
a pilot and an operator for the navigation and bombing system. It could carry up to 10,495 pounds of bombs and eight forward-firing
20 millimeter cannon. The project was cancelled in 1951. The two prototypes continued to fly by participating in tests of their
advanced aerodynamic and weapons-handling features. Both were eventually lost in crashes laid to pilot error.

A very clean design!.
