Deciding to produce and deploy medium-range fire support mobile suits to complement its close-combat RGM-79 GM units, the Earth Federation Forces took the plans and combat data from the RX-77-2 Guncannon prototype developed under Operation V and refined the design for mass production. The new RX-77D Guncannon Mass Production Type first came off the assembly lines in the last weeks of UC 0079. To cut costs, the costly and complicated Core Block System was removed, and the original Guncannon’s expensive Luna Titanium armor was replaced with more affordable titanium ceramic composite armor. However, its performance was greatly increased with the addition of more verniers and more powerful rocket thrusters. Since the Guncannon had such heavy armor, it had no need for a shield and could carry two machine guns. Due to its late entrance into the One Year War, the Guncannon Mass Production Type saw a somewhat limited production run, with two units assigned to the Scarlet team stationed aboard the assault carrier Gray Phantom and at least one unit assigned to the White Dingo team in Australia.
