The MSM-07 Z’Gok was a mass production amphibious mobile suit developed by MIP Company for the Principality of Zeon.

The “MS” in the type code referred to it being a mobile suit, while the “M” identified it as an amphibious model. The “07” indicated that it was the seventh design in the line.

History

During the One Year War, the Principality of Zeon started to push its ground offensive on Earth. While it had developed the MS-09 Dom for ground use, its fusion reactor was unable to power mega particle weaponry. A fusion reactor with sufficient power output required a more efficient cooling system, and Zeon identified seawater as a potential coolant. This led to the development of amphibious mobile suits that would also allow Zeon to gain sea superiority.

Building on its successful MS-06 Zaku II models, the Zeonic developed the MS-06M Zaku Marine Type variant for underwater combat. After this proved unsuccessful in battle, Zeon command ordered MIP Company and Zimmad to develop dedicated amphibious mobile suits.

The Z’Gok went down in history as the most successful amphibious mobile suit design. It was fast and agile both on land and in water. When Zeon launched its assault on the Earth Federation underground headquarters of Jaburo on 30 November UC 0079, one of the primary attack groups consisted of many Z’Gok units that bypassed the base defences via a secret underwater entrance.

Zeon Remnants deployed several Z’Gok units in the Antarctic Circle in UC 0080. The Z’Gok also served in the South Seas Alliance defence forces around that time. In UC 0096, several units participated in an attack on Torrington Base in Australia.

Design

Both the MSM-03 Gogg designed by Zimmad and the MSM-04 Acguy designed by Zeonic used ballast water tanks to cool their reactors. However, these tanks were bulky and weighed the mobile suits down. MIP Company developed the Z’Gok to use a propeller cooling system instead.

When submerged, the propellers drew water into the mobile suit to remove heat from the reactor. On land, the propellers sucked in air for cooling. This allowed sufficient cooling regardless of the operating environment.

The improved efficiency of the propeller cooling system meant the Z’Gok could use a more powerful reactor. Its Minovsky fusion reactor generated 2,480 kW, allowing it to operate two mega particle cannons.

It used hydrojet thrusters with a total output of 83,000 kg for propulsion. Despite having less powerful thrusters than the Gogg and Acguy, it was much lighter without ballast tanks. The Z’Gok achieved maximum speeds of 70 km/h on land and 103 knots in water.

The mobile suit used a modular forearm system that allowed it to switch weapons, making a team of these mobile suits a versatile strike force. Unlike the Gogg and Acguy that used super hard steel alloy armor, the Z’Gok had next-generation titanium ceramic composite armor.

Armaments

The Z’Gok’s standard weapons were mega particle cannons for ranged attacks and iron nails for melee combat.

Mega particle cannon

The Z’Gok had a mega particle cannon built into each forearm. These were powered directly by the Z’Gok’s reactor and offered a high firing rate thanks to the efficient cooling system. The forearm mounting provided natural aiming and a larger firing angle.

Iron nail

The Z’Gok had iron nails mounted on its claws for melee combat. Using the momentum generated by the mobile suit’s powerful thrusters, the nails could destroy a Federation RGM-79 GM with a single blow.

Rocket launcher

Six 240 mm rocket launchers were built into the top of the Z’Gok’s head. Each launcher carried five rounds of magazines, providing thirty missiles total.
