  • Koryu Submarine (Military) - Re-designed for use by DEST troopers during Davion's 3025 campaign on Galtor. One of these subs was used to deliver a DEST squad on their mission to enter and destroy a Davion underwater command base in May, 3025. The ship was refitted with a Fusion Engine and given a single-shot two-tube Short Range Torpedo Launcher mounted in the bow. It is unclear if this ship survived the Command Center's explosion. BV (2.0) = ?[2]
