The RX-77-01 Guncannon is a mobile suit featured in the Mobile Suit Gundam: The Origin manga. It was used during the One Year War by White Base during their journey from Side 7 Jaburo.[1]

Technology & Combat Characteristics



Guncannons and Guntanks were used as mock targets for the RX-78-01 Prototype Gundam's beam rifle. Sergeant Ash's discovered the remains of several when they infiltrated Side 7.[2]

By the time Amuro Ray boarded White Base with the approval of the injured Captain Paolo Cassius, Unit-01 was in the starboard hangar of White Base and the RX-78-02 was stored in front of it.[3]
