Essentially a mobile battery, the Luna Tank was developed for lunar surface defense in place of the more valuable mobile suits. It was armed with eight 2-barrel solid shell cannons over its spherical chassis. Originally, it was operated by one pilot and four gunners. Later, due to improvements to the fire control system, the number of gunners was reduced to two. In addition, the experimental unit used to test the Plasma Leader could be controlled by one pilot and one gunner.
The Luna Tank was equipped with a pair of caterpillar treads. Since these were only intended for use under lunar gravity, they were far smaller than the chassis and only had a maximum speed of approximately 30 km per hour. In combat, it relied on the rocket engines below it for flight. 25% of its chassis was dedicated to propellant storage space, and it was able to maintain flight for one hour.
The purpose of the four panels on the sides of the chassis is unclear. Despite their resemblance to solar panels, they were most likely Minovsky Craft or a type of support flight system.[3] The Luna Tank would eventually become the basis for the MAX-03 Adzam, the first mobile armor.
