US Submarine Participates in JMSDF SUBCOMP

FLEET ACTIVITIES YOKOSUKA, Japan – A U.S. Navy Los Angeles-class attack submarine is participating in the Japan Maritime Self-Defense Force (JMSDF) Submarine Competition (SUBCOMP), Feb. 13.

SUBCOMP is designed to evaluate and test Japanese crews across multiple platforms on their ability to conduct various aspects of anti-submarine warfare. The inclusion of U.S. Navy assets in the exercise also provides an excellent opportunity for bilateral integration and coordination in an anti-submarine warfare environment for both the U.S. Navy and the JMSDF.

In addition to the U.S. submarine, this year’s SUBCOMP will feature several JMSDF submarines, four aircraft wings, an aircraft squadron and five JMSDF ships including the Hyuga-class helicopter destroyer JS Ise (182). The top performing crew will be recognized with the Japanese Battle Efficiency Award.

“The success of September 2017’s engagement is an indication of how valuable this training is to our readiness and bilateral cooperation,” said Capt. John Stafford, the Submarine Group 7 Deputy Chief Of Staff for Operations. “This is the kind of anti-submarine exercise our crews train for at home and practice at sea. We’re pleased that our boat will have the opportunity to put their training to good use and we look forward to the opportunity to showcase our skills while working with our Japanese counterparts in a forward-deployed environment.”

“We are very pleased to have a U.S. Navy submarine play a role in this year’s Submarine Competition,” said CAPT Toshiaki Hoshina, Deputy Chief Of Staff for Operations, Commander, Fleet Submarine Force, who will be organizing the exercise. “Their participation will significantly improve our interoperability and strengthen the partnership among our forces.”

During the exercise, a U.S. Navy sonar technician from the U.S. Pacific Fleet Navy Data Center will embark a JMSDF submarine.

“As we expand our role in the Indo Pacific, I hope we will continue to develop our capabilities along with our allies, and aggressively pursue these opportunities to hone our skills in this vital and dynamic region,” said Stafford.

COMSUBGRU 7 directs submarine activities throughout the Western Pacific, Indian Ocean and Arabian Sea; two forward-deployed submarine tenders and four attack submarines homeported in Guam; five surveillance towed array sensor system vessels and three oceanographic survey vessels when tasked for theater anti-submarine warfare operations.
