 HAVE LEMON involved a number of Ryan Firebees equipped with a weapons pylon under each wing, a forward-looking TV camera, and a datalink mounted in a pod on top of the vertical tailplane.These UAVs were given the designation "BGM-34A" and used beginning in late 1971 to perform remote-control strikes on simulated air-defense sites with Maverick missiles and HOBOS TV-guided glide bombs.The results were good enough to permit follow-on development, resulting in the "BGM-34B", which featured an extended nose to accommodate an infrared imaging system (some sources say low-light-level TV) and laser designator for targeting and control of laser-guided bombs.
