MSM-03C Hi'Gogg
One of the earliest designs for an amphibious mobile suit was the MSM-03 Gogg, and while being their first truly successful amphibious design, it did have its limitations. To overcome these, the improved MSM-03C Hygogg was developed, and it differed quite a bit from its predecessor in both appearance and abilities. Its outer form was refined, making it more streamlined and increasing its water movement speed. The mega particle guns mounted in the original Gogg's stomach was moved into the Hygogg's hands, allowing for much greater flexibility in its attacks. The Hygogg could also mount a large "hand missile unit" over each arm, equipped with a set of blow-away panels to protect the mobile suit from the blast of the rather large and heavy missile when launched. Only a limited number of these experimental units were built, with three units operated by Zeon's Cyclops Team special forces unit in a raid on the Earth Federal Forces' Arctic base in December UC 0079
MSM-07E Experimental Z'Gok
Following their invasion and occupation of many areas of Earth during the One Year War, the Principality of Zeon military began developing amphibious mobile suits to increase its war capabilities in Earth's oceans and waterways. One of the most successful designs was the MSM-07 Z'Gok, though MIP Company continued to improve this model. This upgraded model was called the MSM-07E Z'Gok-E ("E" for "experiment"), and while similar to its predecessor, it featured many improvements, the most visible being the ability to draw its arms and legs up closer into its body, making the Z'Gok-E more streamlined and faster while moving underwater. Propellant storage for its thrusters were moved from its main body into tanks mounted inside the arms, with energy caps installed in the hand-mounted beam guns, making them able to store up power from the generator and discharge a rapid-fire, machinegun-like burst when required. With this increase in handy firepower for both underwater and land combat, the original missile tubes mounted in the head - which could only be fired out of the water - were replaced with torpedo tubes, giving it additional firepower while operating underwater. Only a limited number of these experimental units were built, with one unit operated by Zeon's Cyclops Team special forces unit in a raid on the Earth Federal Forces' Arctic base in December UC 0079.

Magella Attack
The backbone of Zeons Terretrial forces is the Magella Attack Tank, a deciedly unconventional type of main battle tank. The vehicles detachable turret can fly for short distances, functioning as a crude attack plane with apowerful 175mm cannon. The remnants of Ramba Ral's commando team use these "Magella Tops" during their final attack on the White Base.
Gallop & Cargo
The Gallop is a large hovercraft capable of carrying three mobile suits, which serves a s Ramba Ral's mobile Headquarters during his persuit of the White Base. Its jet engines allow the gallop to travel at high speeds, it can prode covering fire with its rear mounted gun turret. After the destruction of the gallop, Crowley Hamon converts its trailer module - known as the "Cargo" - into a makeshift substitute.
Dopp
Zeon's standard fighter plane uses an unusual modular design,with a windowed cockpit and two engine pods sitting-atop a small fuselage.Highly manueverable, and armed with vulcan guns and missile launchers, the Dopp is a more dangerous an opponent than its bizzare apperance might suggest.
Dobdai YS
In order to extend the range of their Gouf mobile suits ,Zeons Terrestrial forces have adapted the Doai bomber into a makeshift flying platform. Once safely tethered to the Dodai, the Gouf can take to the air and bedevil the vulnerable aircraft of the federations's supply corps.
the Grapzepplin
the Grapzepplin class Battleship was Flagship of the Zeon fleet in the European theater of Earth. With a capacity of 48 mobile suits and a battery of bow-mounted mega particle guns,the Grapzepplin class Battleship is used for ferrying mobile suits across the front, the Grapzepplin was often used as the command ship for smaller fleets when a Gallop class battleship was either unavailable or unsuitable. Lacking the Pegasus class' integral Minovsky Craft System, the class mobile Land Battleship could only operate for short periods in Earth's atmosphere, using sustained thrust. Several mobile Land Battleship class vessels carried the bulk of the remaining Zeon forces at Odessa into space, including a large shipment of resources mined in the mineral-rich region. Another was used by Ginias Sahalin in Zeon's Southeast Asia base as a power supply for his massive mobile armor Apsalus III. The mobile Land Battleship class, like most Zeon warships of the One Year War, had (4) launch catapults,or could instead deploy its complement of mobile suits through two Mobile Suit Storage Hangar bays, accessible by (2)hatch on the ventral hull.
Jukon
These submarines, the backbone of Zeon's naval power, are redesigned versions of Federation vessels captured during the Earth invasion. In addition to its torpedo launchers and missile silos, the standard Jukon can carry a pair of mobile suits in the hangar beneath its bridge.
