As the focus of the One Year War shifted into space, the Earth Federation Forces began designing a new Gundam for high mobility space combat, and the end result was the RX-78-4 Gundam 4th. The Gundam 4th was intended to serve as an anti-ship combat unit capable of high speed attacks. The Core Block System from the RX-78-2 Gundam was removed, and the suit was equipped with a new backpack that featured additional thrusters. With the new thrusters and propellant tanks, the Gundam 4th’s mobility was improved by about 40 percent. The removal of the Core Block System allowed for the installation of cooling systems, which translated to a higher generator output and the ability to use higher power beam weapons. The Gundam 4th featured standard armaments like a pair of vulcan guns and beam sabers, plus a pair of forearm-mounted hand beam guns. It could also carry a beam rifle and hyper beam rifle, but its most powerful armament was the powerful mega beam launcher, which was powered by an external generator pack mounted on the backpack. The launcher had the capability to destroy an entire fleet on its own, but proved unstable in drawing power from the suit’s reactor. In late UC 0079, the Gundam 4th was assigned to Luce Kassel, a pilot aboard the assault carrier Thoroughbred. The RX-78-5 Gundam 5th, piloted by Ford Romfellow, was also stationed aboard the same ship. Luce used the mega beam launcher in battle to destroy a Zeon fleet, but the strain on the generator was too intense and caused an explosion that destroyed the cockpit and killed Luce.
