JS Muroto (ARC-483) is a cable laying ship of the Japanese Maritime Self-Defense Force.
Development and design
The second generation Muroto was built with a budget in 2009 as a successor ship due to the deterioration of the predecessor Muroto (ARC-482). As with its predecessor, it seems that its main task is to install underwater hearing monitoring equipment at bases, ports, strategic sea areas, but details are not disclosed. It is equipped with cable laying equipment and various underwater equipment related to marine surveys, and the hull is equipped with bow thrusters and azimuth thrusters for smooth operation. In addition, the hull has a commercial ship structure as much as possible in order to keep the ship price down, and it is within the range that can demonstrate the minimum capacity as a laying ship.
