The MS-09F/trop Dom Tropen is a mass-production ground combat mobile suit first featured in the OVA Mobile Suit Gundam 0083: Stardust Memory. Its design was later updated in the novel Mobile Suit Gundam Unicorn. The unit is piloted by Gaily and Adamski.

A redesigned version of the MS-09F Dom Funf, the Dom Tropen was developed to operate exclusively in tropical regions on Earth, in particular the desert areas. Introduced by the Zeon military late in the One Year War, it also incorporated data taken from the MS-09 Dom and YMS-09D Dom Tropical Test Type. Compared to previous Doms, it is a machine that takes into consideration aerodynamic shape and maintainability. The basic structure of the head unit is closer to that of the MS-09R-2 Rick Dom II than to that of the Dom, and the top of the head is equipped with a sub-sensor. The mobile suit featured modified intake filters for its leg-mounted thermonuclear jet engines, allowing it to retain its high ground hovering speeds without fear of sand ruining the engines. In addition to dustproof air filters and enhanced cooling devices in various parts of its body for desert and hot weather specifications, the Dom Tropen has specialized block-shaped armor designed to facilitate the removal of sand that enters the interior. Armament compatibility has also been thoroughly improved, making it possible to equip anything other than beam weapons.
