The FA-78-1 Full Armor Gundam, also known as Gundam Full Armor Type or Full Armor Gundam (Type A), was a variant of the RX-78-2 Gundam introduced in the original design series Mobile Suit Variation.
The FA-78-1 Full Armor Gundam was the RX-78-2 Gundam equipped with a set of optional armor, weapons, and auxiliary propulsion systems designed as part of the FSWS Plan, an enhancement plan for the RX-78 Gundam series. The plan was intended to improve the performance of RX-78 type units for use by Newtype pilots. The FA-78-1 equipment was planned to be equipped by the Gundam after it had undergone Magnet Coating treatment.[3] This equipment was fully modular and could be easily equipped or removed. The optional armor that was a part of the equipment was applied to frequently damaged areas: chest, shoulders, waist, arms, and legs.[
The FSWS Plan, initiated in the late stage of the One Year War, was designed to enhance the RX-78 series' performance for Newtype pilots, with the ultimate goal of creating a set of optional weapon systems for every RX-78 unit, to serve as the mobile suits of an all-Newtype team. The first unit of this plan was the FA-78-1 Full Armor Gundam.
