What you see is the proof of concept glider. The Coal Powered Ramjet version was slightly Larger. I believe the University of Kansas once put out a book of Lippisch's development of the Delta Wing in Germany. If I can dig out of one of my storage box's I will get the ISBN number for you. After the war he was brought to America (I don't know if it was through project paperclip) and he went to work for Convair/General Dynamics (Not sure when the name changed). There they developed the XF-92 Delta Wing proof of concept aircraft which then led to the F-102. The original F-102 looked very much like a scaled up XF-92, however, it was drastically redesigned when they discovered area ruleing (Whitcomb?). From there they had the B-58 and the F-106. Finally there is the F-16 which has a delta wing, but it isn't tailess and with FBW for the RSS (Relaxed Static Stability..the F-16 is unstable[e.g.- the CG is ahead of the AC] at subsonic speeds) at subsonic speeds the control concept is quite different from a naturally stable delta.
P.S.-I believe `Kingfisher', their competitor to the SR-71 also had a Delta Wing.
