During DSEI 2015 which took place in London from 15-18 September, UK based engineering company SubSea Craft unveiled a revolutionary new submersible called the Diver Delivery Unit (DDU). The DDU is modular and offers mission-specific capability on and under the surface. It is scalable and reconfigurable for a variety of roles. The DDU features a unique catamaran design and can deploy up to 8 special forces operators including the crew of two.
Of course, it seems about 2-3 times too wide for U.S. Navy submarine dry deck shelters, but could have some use from surface ships with well decks such as LSDs, LPDs, LHDs etc. Or maybe Independence-class tri-hulled LCS platforms(?)
