Here’s a model I quite recently completed, based on the excellent 1/200 Hasegawa 767 kit. The conversion is only based on pictures found on the web, so may not be 100% accurate. The conversion mostly consists in adding the dorsal ‘bump’, here made of blocks of ureol (some kind of reconstituted resin), epoxy putty (Milliput) and plastic card. Ureol is easily carved and sanded.
Two strakes grace the rear bottom fuselage.
I decided to represent the aircraft as it stood early in the 2010s in desert conditions somewhere in Calfornia after the programme termination. This helped the actual conversion since a lot of detail is hidden by the materials used to seal up the aircraft. Engines are missing too.
AST stands for Airborne Surveillance Testbed.
This was a US Army project, based on a conversion of the very first 767 built, and tested as an early warning system detecting launches of ballistic missiles during the 1980s,1990s and 2000s. The programme was terminated, probably because satellites ended up doing do the job better. The USAF had its own AST programme using 747s.
