The HMSVO (standing for High Speed Multi-hull Vessel Optimisation) project is being conducted to improve design and performance evaluation capabilities for multi hull ships. The US Navy's NAVSEA Carderock division and Japan's MoD ATLA are cooperating on the project. Navy Recognition was told that the US design differs from the Japanese design however.

The project started in 2014, is set to end in 2018 and today ATLA naval architects and engineers are still testing the concept both via CFD and through the use of a scale model. Ultimately, the JMSDF may decide to give the concept a go ahead and move to detailed design... or not.

The trimaran concept measures 92 meters in length, 21 meters in width and 4 meters in draft for a displacement of 1,500 tons and a maximum speed of over 35 knots. The crew complement of the vessel is about 50 sailors. The trimaran has a range of 3500 nautical miles at 15 knots.

The hull form features three active ride control systems which significantly reduce pitch and roll motion.

The helicopter deck and hangar can accommodate a 14 ton (Merlin type) helicopter. HMSVO's is a full aluminum ship. The scale model on display at the show features a 76mm main gun by Oto Melara, a Phalanx CIWS on top of the helicopter hangar, three diesel engines and three waterjets and a mutli mission bay (over 730 square meters in surface).

For mine counter measure (MCM) missions, the trimaran can be fitted with 2x 40 feet containers for UUVs and their control units. In addition, 16x MCM UUVs can be stored in the multi mission bay. UUVs are launched and recovered with an overhead boom crane at the stern. The MCM configuration also includes 2x 11 meters MCM USVs, 1x VTOL UAV and 1x airborne MCM helicopter.

The disaster relief configuration consists in 7x 40 feet containers, including medical ones.

The offshore patrol / special operations support configuration consists in 2x containers, 8x 7 meters RHIBs, 2x 11 meters RHIBs for VBSS teams, 1x ISR UAV and 1x helicopter.
