The Maritime Self-Defense Force (MSDF) is promoting the improvement and consolidation of its facilities in Yokosuka City, where its district headquarters, regional fleet command, and other operational functions are concentrated. This is part of efforts to beef up defense capabilities through integrated operations of the Ground, Maritime, and Air SDF in light of the worsening security environment. A “maritime operations center” will be completed at a site northwest of the Self Defense Fleet headquarters in Funakoshi, Yokosuka City, in January 2020.
According to the MSDF and the Defense Ministry, this new center will consist of a building with six floors above ground and two below ground, with a total floor area of 36,000 square meters. The headquarters of the Self Defense Fleet, Fleet Escort Force, Fleet Submarine Force, and other units, currently in different locations, will move to the new building.
Upon the completion of the new center, the MSDF will install a new command and communications system to enable integrated management of the information and operations of its units. It will strengthen cooperation with the Ground and Air SDF, as well as the U.S. Forces and the relevant ministries. It will put in place a rapid response system for contingencies and major disasters. Three nine- to ten-story buildings will also be built nearby to be used as housing for SDF members. Measures will also be taken to enable SDF personnel who need to be mobilized in emergencies to live near their workplaces.
In addition, a port facility with a pier measuring 200 meters in length in waters 10 meters deep will also be completed this summer at the Nagaura Port. State-of-the-art Soryu class submarines will be homeported there and there will also be a fuel storage facility. Six large ammunition depots for the new missile interceptors used on Aegis ships will also be built nearby in FY21. (Slightly abridged)
