A hovercraft-based land battleship, the Big Tray was propelled by thermonuclear jet engines and capable of rapidly traversing all terrains, including water. It was armed with three triple gun turrets, two pointed at the front and one located at the rear. At the front of the ship are two large caliber cannons. The variant used by the Far Eastern Front Army replaced the front cannons with mega particle cannons for increased firepower.

Despite its heavy firepower, it was mostly intended to serve as a mobile command center for generals, and contained a large command room in its bridge. Under Minovsky particle interference, it relied on its embarked Dragonfly reconnaissance aircraft to search for enemies. The Big Tray-class normally carried such aircraft on a landing deck behind the bridge, though it was also capable of carrying and supporting mobile suits. While uncommon, some iterations of the Big Tray-class were seen with aft mounted hangars capable of carrying tanks and trucks in a support tole.
