T-171E-3 20mm rotary cannon in the tail of a Convair B-58 Hustler
Defensive armament consisted of a single 20 mm T-171E-3 rotary cannon with 1,200 rounds of ammunition in a radar-aimed tail barbette. It was remotely controlled through the Emerson MD-7 automated radar fire-control system, only requiring the DSO to lock-on a selected target blip on his scope and then fire the gun. The system computed aiming, velocity or heading differential, and range compensation.
