Mobile Suit Gundam: Omega
The RX-75-4 Guntank is an artillery mobile suit that often acts as a support unit to the other mobile suits.
Technology & Combat Characteristics
The RX-75-4 Guntank was the first prototype Earth Federation mobile suit developed by Project V. However, the Guntank was hardly a mobile suit at all. The Guntank had the torso and arms of a mobile suit, but possessed caterpillar treads for legs. It also lacked any sort of hands and had a canopy-style cockpit on the head, along with the cockpit in the torso. Like all “V Project” mobile suits, the Guntank used the Core Block System.
The main weapons of the Guntank are twin 180mm recoil-less cannons, which were effective at both long and medium ranges. The Guntank’s two arms ended in four-barrel missile launchers instead of hands. These weapons provided good cover fire against enemy tanks and aircraft, but were less effective against enemy mobile suits.
The major flaw in the Guntank is its inability to turn the torso. This means the cannons can’t aim horizontally and is difficult to aim the cannons at moving targets, as the Guntank must reposition itself. Another major flaw was that its design was primarily aimed towards ground combat, and suffered heavily in space due to poor maneuverability.
180mm Low-Recoil Cannon
Two 180mm Cannon is equipped on the shouders of the Guntank. The cannons are used for long range artillery and sniping. It has a firing distance of 260km, which exceeds visual range.
4-tube 40mm Bop Missile Launcher
Two 4-tube 40mm Bop Missile Launcher are mounted in the Guntank’s manipulators with an ammunition feed system. It fires small anti-aircraft missiles with a range of 20km. As the Guntank is not equipped with any close range weapon, 4-tube 40mm Rocket Launchers are used as the primary defense weapon.
The Guntank was developed when the first rumors of the Principality of Zeon’s mobile suits reached the Federation. The Guntank was designed as an anti-mobile suit and artillery mobile suit. Although its performance in this role fell below expectations, it did pack a heavy punch.
At the attack on Side 7, only one of the RX-75-4 Guntank units survived the attack. The last prototype made its way to the Pegasus-class assault cruiser White Base. The Guntank design fought alongside the RX-77-2 Guncannon and the RX-78-2 Gundam, but it was easily outclassed by them. However, after the death of the Guntank’s pilot Ryu Jose, the mobile suit was upgraded to be used by a single pilot in the canopy-style cockpit. The RX-75-4 Guntank was finally decommissioned at the Federation’s General Headquarters at Jaburo, South America in November UC 0079.
However, despite being decommissioned, it did not stop the Earth Federation Forces from developing variations of the Guntank such as the RX-75 Guntank Mass Production Type.
