Technology & Combat Characteristics
The HFA-78-3 Heavy Full Armor 7th Gundam was armed with heavy weapons designed to take out a single enemy fleet and is set to carry out assault operations with high efficiency and heavy firepower. The HFA-78-3 Heavy Full Armor 7th Gundam's concept is similar to the FA-78-1s Full-Armor System and Weapon System(FSWS) scheme, and is theoretically the ultimate development of the RX-78-7 7th Gundam. The equipment features a Long Range mega particle gun similar to a battleships main gun, allegedly powerful enough to sink a Musai Class light cruiser at long-range. In addition, in order to meet the needs of a variety of operations scenarios, it's equipped with various types of missile launchers, a Hyper Bazooka, long range cannons, grenade launchers and hand beam guns. Because the HFA-78-3s large body size and numerous weapons needed a considerable amount of energy to function normally, the design team for the Heavy Full Armor system developed a large-sized engine installation, fuel tanks and additional vernier thrusters for extra power and mobility.
History
The Earth Federation's Phantom Sweep unit leader Hugues Courand pilots the HFA-78-3 Heavy Full Armor 7th Gundam to battle Principality of Zeon remnants Invisible Knights in space.
In Gundam EXA, the Heavy Full Armor 7th Gundam appears in a flashback of EX-, who used it to join in battle of A Baoa Qu. Although EX- was confident that its power would allow him to gather the data on a Newtype, he only found the wreckage of the RX-78-2 Gundam, with the Core Fighter ejected. Frustrated at his failure, EX- and the Heavy Full Armor 7th Gundam start wreaking havoc without thinking. The commotion soon catch attention from Ford Romfellow and Luce Cassel, who recognize it and realize that it shouldn't exist there since the RX-78-7 7th Gundam is still under construction. This disturbance proved to be too great for General Answer to handle, and its record of the events was damaged beyond recover.
