ZAFT designed various mobile suits to attain supremacy over Earth during the Bloody Valentine War. The UMF-4A GOOhN was one of two suits designed specifically for amphibious combat, along with the UMF-5 ZnO. As an aquatic unit, the GOOhN could transform into a swim mode to travel at high speeds and ram enemy mobile suits or vessels. Aside from the main GOOhN, ZAFT also produced the experimental variant UTA/TE-6 G00hN Underground Mobility Test Type. The GOOhN was more heavily armed than the ZnO, but it featured the same main weapon: the phonon maser high-powered lasers that could travel through water. Other armaments included two 7-barrel missile launchers mounted on the forearms, along with a rifle dart launcher and supercavitating missile launcher. In combat, GOOhNs were usually deployed from Vosgulov class submarines and operated in conjunction with ZnOs and on occasion the UWMF-1/S GINN WASP Type. GOOhNs were widely used across Earth’s oceans, and many units participated in Operation Spit Break, an unsuccessful attack on the Earth Alliance’s JOSH-A base in Alaska.
