Technology & Combat Characteristics
Manufactured by Anaheim Electronics, the RX-77 is the Earth Federation's first attempt to manufacture a mobile suit based on observation data of the Autonomous Republic of Zeon's YMS-03 Waff and MS-04 Bugu. While in terms of technology it was sufficient, the Earth Federation geared the unit towards anti-ship combat. Thus, during the Battle of Mare Smythii, the squadron of 12 RX-77-01 Guncannon units were wiped out by 4 MS-05 Zaku Is and a MS-04 Bugu piloted by Ramba Ral. This illustrated to the Federation of Tem Ray's proposal for a mobile suit that is geared toward mobile suit combat, leading to the approval of the RX-78 Gundam Development Project.
