SRF-JRMC Yokosuka Operations

SRF-JRMC has been continuously managing and performing ship maintenance in Yokosuka since it’s establishment as the "Ship Repair Department", Fleet Activities, Yokosuka on 28 April 1947, with an Officer-in-Charge and a staff of 75 U.S. Navy personnel and 576 former Japanese Imperial Navy employees. On 15 August 1951, the facility was officially designated the "U.S. Naval Ship Repair Facility". In March 1976, SRF established a Sasebo office with a staff of seven Japanese employees. Then on 01 March 1984, U.S. Naval Ship Repair Facility Detachment, Sasebo was officially established. Commonly known as “SRF”, the command became U.S. Naval Ship Repair Facility and Japan Regional Maintenance Center, or SRF-JRMC, on 01 October 2004 with the merger of the Fleet Technical Support Center Pacific Detachments and other maintenance elements. SRF-JRMC reports to the Director for Fleet Maintenance, U.S. Pacific Fleet, (N43) with technical authority from U.S. Naval Sea Systems Command.

SRF Yokosuka and Det Sasebo are responsible for maintaining the 22 ships of the Forward Deployed Naval Forces (FDNF) serving in the U.S. SEVENTH Fleet. This includes USS BLUE RIDGE (LCC 19), the flagship of Commander, U.S. SEVENTH Fleet and the nuclear-powered aircraft carrier USS RONALD REAGAN (CVN 76), the only U.S. nuclear powered aircraft carrier permanently based outside the continental U.S.

SRF-JRMC Yokosuka is essentially a full-service, non-nuclear naval shipyard providing modernization, maintenance and repair to U.S. SEVENTH Fleet ships through depot-level maintenance availabilities (including dry-dockings), Continuous Maintenance (CM), Fleet Technical Assistance (FTA), and emergent/voyage repairs (VR). SRF-JRMC has a large, organic Japanese National workforce in Yokosuka, supplemented by local private contractors.

During a “typical year”, SRF Yokosuka plans and executes 400,000 to 450,000 man-days of depot-level work on U.S. SEVENTH Fleet’s FDNF Yokosuka and deployed ships. SRF accomplishes approximately 80% of the port workload with its organic workforce. Of significance, SRF-JRMC has annual maintenance availabilities on USS RONALD REAGAN (CVN 76) and USS BLUE RIDGE (LCC 19).

Yokosuka dry-docking facilities can support timely dry-docking of most ships in the U.S. Navy inventory. Facilities include 6 graving docks with a combined displacement of 530,000 tons, 19 wet berth locations, 10 industrial buildings with combined workshop space of 960,000 square feet, and 15,300 combined feet of pier to support maintenance, including a pier specifically designed for the carrier.

SRF-JRMC employs nearly 120 U.S. military, over 325 USCS civilian personnel, and nearly 2500 full-time Japanese Nationals (including nearly 350 in the Sasebo Detachment) throughout the organization.
