I was at either South Weymouth Mass or Patuxent River Maryland where this was under development. The electronics filled most of the rear of the aircraft including test equipment. It was so heavy that it tweaked the fuselage and was limited in flight.I don't expect you guys to do this one, I've just never seen it before.
It is an EC-121L (WV-2E) a testbed for rotating radar dome with an AN/APS-70 radar.
