| 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.

| Stephan Wilkinson, e-mail, 03.10.2013 20:56 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. reply | | guba, 21.06.2011 06:02 simply built unaltered from German blueprints captured in 1945. reply | | a.casais, e-mail, 24.11.2010 20:58 it is a real family of the ME-163 "Comet" almost twins reply | | Arn, e-mail, 27.01.2009 06:31 Like many early "X planes", this one looks as though it was simply built unaltered from German blueprints captured in 1945. reply |
