Technical and Historical Data

Of the three pre-production Federation mobile suits, the RX-77 Guncannon lineup had the most success in achieveing mass production. The Gundam was deemed too costly (even though a limited number were built exclusively for land combat) and the Guntank failed to be versatile enough, but the Guncannon fit right in with the Federation's war policy.

The RX-77D Guncannon Mass Production Type is built off the same frame as the original Guncannon unit. It is not armored with the highly durable lunar titanium armoring as a cost cutting measure, but it is still quite tough in combat. Three gigantic thrusters on its backpack give it excellent mobility for such a heavy (by Federal standards) total weight, allowing it to quickly relocate while attacking an enemy at long range, and also offer a good reaction time in close-quarters combat.

The Guncannon MPT is armed with the traditional set of head-mounted vulcan guns. Its primary assault weapons are a set of collapsible 200mm artillery cannons. These have a heavy payload and are very accurate at range, as well as posess a good refire rate. The barrels fold and are stowed inside the Guncannon's backpack when not in use. The Guncannon MPT also carries standard GM weaponry to increase its ability to lay down a heavy suppressing barrage. While its reactor is insufficient to carry a full fledged beam rifle, they are commonly armed with beam spray guns as well as the GM Commands higher yield but slightly less accurate beam gun.

Some Guncannons are refitted for shoreline defense as special Harbor Defense Types, one of their cannon mounts replaced with an 8-rack SUBROC launcher for destroying Zeon amphibious assault units before they reach the shore. Units commonly equipped in this capacity on coastal bases are repainted blue.
