The MS-09B Dom is a heavy, high performance MS developed by Zimmad, with an emphasis on ground combat. The combined thrust of the thermonuclear jet engines and the chemical rockets built into the legs allows it to hover at high speed over the surface of the Earth. Furthermore, a block structure has been introduced into the body. In addition to the performance of the machine itself, its main armament, the 360mm Giant Bazooka, boasts firepower that surpasses that of previous Zeon mobile suits, and it can be said to be a machine that combines offensive power, defensive power, and mobility at a high level. Due to its high performance, the Dom soon replaced the MS-07 Gouf as the Zeon forces' main ground unit. Several units were shipped to South East Asia.
