The RX-77-3D Guncannon Heavy Type D was a variant of the RX-77-3 Guncannon Heavy Custom. The Type D was designed for improved mobility and featured additional verniers on its backpack and legs. Its shield acted as a balancing counterweight when the suit jumped in the air. In addition to the armaments carried over from the RX-77-3, the Type D also mounted a forearm shield and could use cracker grenades and a 380mm rocket bazooka. Only a few Type D units were produced before the introduction of the more advanced RX-77-4 Guncannon II.
