ZMT-D15M Galguyu

An experimental transformable mobile suit/mobile armor developed for underwater combat, BESPA’s ZMT-D15M Galguyu was based loosely on the space use ZM-D11S Abigor. Although smaller and much lighter than the big-and-heavy Abigor, the Galguyu was developed around the same basic concept: a high speed mobile armor form for submarine-like mobility, and a mobile suit form for close combat both underwater and ashore. The mobile armor mode’s primary armament was its torpedo launchers; however, being torpedoes, these weapons were good only underwater and completely useless when operating on land. The mobile suit form was armed with a pair of beam guns and beam sabers, but it proved to be less-than-impressive in combat out of the water. The nose cone of the mobile armor mode itself was also a large missile; however, once it was fired, the mobile armor’s mode then suffered in terms of hydrodynamics. In the end, like the Abigor, the Galguyu proved to be a flawed design. Part of this failure was due to the fact that the Galguyu was rushed to the frontlines without prior and proper underwater testing, and the mobile suit’s water seals were inadequate, leaving the Galguyu often in the bad situation of taking on water.
