The RTX-440 is a modification of the anti-MS tank RTX-44. The machine cannons equipped on left manipulator are an improved 2-tube model which has longer range than the older 4-tube model on the original Guntank. In addition to the bop gun and 220mm cannon, the RTX-440 can be armed with numerous optional weapons including Multi Launch Rocket System (MLRS), rocket launchers, heavy mines and a flamethrower.

The RTX-440 have a very limited degree of flexibility of its torso - unlike the fixed torso of its predecessor, the Guntank - but rigid enough to make it hard to shoot a moving target with its main cannon. In addition, the RTX-440 has a crude transformation mechanism known as "Asssault Gun Mode" that allows it to deploy the secondary caterpillar treads and "crouch" down in similar fashion to a conventional tank. This mode allows the RTX-440 to approach its target with greater speed.

Development of the RTX-440 Ground Assault Type Guntank was one of the many mobile suit projects that the Earth Federation started during the One Year War. Like all of the projects it was descended from the Federation's Project V, specifically from the data of the RX-75 Guntank. However the RTX-440 development project was terminated after Clyde Bettany, the Federation technical officer of the project and lover of the project subordinate Aline Nazon, defected to Zeon with information regarding the RTX-440 Guntank.
