Technology & Combat Characteristics
The Grublo Underwater Bit-Mounted Prototype is a standard MAM-07 Grublo retrofitted with a Psycommu system and a sonar dome attached underneath. It is a type of Quasi-Psycommu system that allows normal pilots to operate the MAM-07-X3. The rear fuselage is equipped with complex transmission units to control the bits. The claw arms are replaced with underwater-use bits.
History
Tests were conducted for about two weeks, during which it encountered two Earth Federation Forces warships, which were sunk in less than an hour. Although the development team was satisfied with its performance, the MAM-07-X3 was not formally adopted for production and is later restored to a standard Grublo.
