Recently, at the 2017 Asia Maritime Aviation System and Technology Exhibition held in Tokyo, the Japan Procurement Technology and Logistics Agency (ATLA) announced its High Speed ​​Trimaran Concept Design (HMSVO). ATLA is a branch of the Japanese Ministry of Defense established in 2015 to "ensure technological superiority and respond quickly to operational needs."

The Japanese Ministry of Defense is conducting an HMSVO project to improve the design and performance evaluation capabilities of multihull vessels. The project was jointly carried out by the Cadillac Division of the United States Navy's Maritime Systems Command and the Japanese Ministry of Defense ATLA. It is known that the design of the United States is different from that of Japan.

The project started in 2014 and will end in 2018. ATLA naval designers and engineers are now testing this concept through CFD and scale models. In the end, the Japan Maritime Self-Defense Force will decide whether to choose a solution and move to a detailed design.

The Trimaran is 92 meters long, 21 meters wide, 4 meters deep, with a displacement of 1,500 tons and a maximum speed of more than 35 knots. It is staffed by 50 people and can reach a range of 3,500 nautical miles at a speed of 15 knots.

The hull is equipped with three active navigation control systems, which can significantly reduce roll and pitch motions.

MSHMSVO is an all-aluminum ship. The ship's helicopter deck and hangar can accommodate 14-ton (Merlin) helicopters. From the scale model displayed at the exhibition, the top of the helicopter hangar is equipped with a 76mm main gun and a "dense array" close-in weapon system, three diesel engines and three water-jet thrusters, and a multi-purpose mission cabin (area Over 730 square meters).

For MCM missions, the ship can be fitted with two 40-foot containers that can carry unmanned submersibles and their control systems. In addition, the multi-purpose mission module can also accommodate 16 anti-mine mines. Unmanned submersibles can be adapted for crane placement and recycling at the top of the stern. The anti-mine configuration also includes two 11-meter anti-mine mine surface vessels, one vertical take-off and landing drone, and one anti-mine mine helicopter.

 Disaster relief is equipped with seven 40-foot containers to accommodate medical equipment.

Maritime patrol / special operations support configuration includes 2 containers, 8 7-meter rigid inflatable boats, 2 11-meter special forces rigid inflatable boats, a reconnaissance drone and a helicopter.
