Northrop X-4 Bantam

The final Northrop flying wing design, although it could more accurately be described as a tailless aircraft, was the XS-4 Skylancer, a transonic research vehicle with two 726kg thrust Westinghouse turbojets. Later redesignated X-4, the first of two aircraft flew at Muroc on 15 December 1948, followed by the second on 7 June 1949. With a span of only 8.18m and weight of 3175kg, the two X-4s completed their research programme in April 1954 and both survive as museum exhibits.

It certainly greatly profited from Me-163 research and development, and Northrop never denied that. But to say it was "simply built unaltered from German blueprints" reveals a lack of real familiarity with both the Messerschmitt and the Bantam. If anything, the X-4 is much more like the DH 108 Swallow.

simply built unaltered from German blueprints captured in 1945.

it is a real family of the ME-163 "Comet" almost twins

Like many early "X planes", this one looks as though it was simply built unaltered from German blueprints captured in 1945.

Do you have any comments about this aircraft ?
