The torso of the Gundam is mostly hollow so that a FF-X7 Core Fighter can dock with it. The Gundam makes use of the Core Block System implemented in the other V Project units. In addition, it was upgraded by Federation technician Mosque Han shortly before the Battle of A Baoa Qu to improve its reaction times, the joints of the Gundam were given a Magnet Coating, based on the experimental procedure performed on the RX-78-3 G-3 Gundam and later used on Amuro's intended successor unit, the RX-78NT-1 Gundam NT-1. The data from the computer was used by the Federation to improve the controls of the Gundam's mass-produced form, the RGM-79 GM. In terms of technology, the Gundam was equipped with a sophisticated Learning Computer which would collect pilot and enemy data during skirmishes and allow the Gundam to operate more effectively. Gundam pilot, Amuro Ray, would make use of the shield as a decoy in many battles, taking advantage of its size to fool the enemy into thinking he was charging at them, then attacking the enemy through the shield. Lastly, it wielded a shield which would offer it a defense against enemy attacks that not even its Luna Titanium body could withstand without damage.

The Gundam Hammer was eventually upgraded for use in space and outfitted with a number of verniers on the ball, and renamed to be the "Hyper Hammer". It also made use of a very unconventional close-range weapon known as the "Gundam Hammer" - a large weapon similar to a flail which could be swung at enemies to deal crushing damage. The Gundam also used more conventional weaponry it could launch rockets with a "Hyper Bazooka", the Federation's answer to the bazookas used by Zeon's Zakus in addition, its head was outfitted with a pair of small vulcan guns, as a way of attacking light-armored aircraft and vehicles without wasting ammo or energy from its more powerful armaments. Those beam sabers could be extended into a spear-like beam javelin, which could be used to stab into an enemy from a longer distance. In addition, it made use of two beam sabers, blades of extremely hot plasma which could cut through any metal with ease. The Gundam would engage in most battles with its beam rifle, making it the first mobile suit to have firepower equivalent to a battleship's beam cannons. Its offensive power was above and beyond that of the Zakus. Built from lightweight Luna Titanium Alloy, its frame was both lighter than that of Zeon's mass-produced mobile suits and much sturdier, able to shrug off a MS-06 Zaku II's machine gun fire with little to no damage. The Gundam was incredibly advanced for its time.
