JMSDF, Australian, US Navies flex mine warfare capabilities

By Commander, Expeditionary Strike Group 7 Public Affairs

The U.S. Navy, Japanese Maritime Self-Defense Force (JMSDF), and Royal Australian Navy (RAN) will commence Mine Warfare Exercise 3JA 2019 off the coast of southwestern Japan, Nov. 18.

USS Pioneer arrived in Nichinan, Japan, for the in-port phase where the crew will work with their JMSDF and RAN counter parts to prepare for the underway portion. Exercise 3JA is part of an annual series of exercises with the U.S. Navy and JMSDF, joined again by the RAN.

“Proficiency within the mine warfare mission is essential to maintaining the security of sea lanes for all nations in the Indo-Pacific region, and the only way to maintain proficiency is to practice,” said Rear Adm. Fred Kacher, commander of Expeditionary Strike Group 7. “We are particularly pleased to practice this fundamental warfare area with our Japanese and Australian allies. The level of learning that we gain together will always be more than we could achieve alone.”

The exercise is designed to increase proficiency in mine countermeasure operations. During the exercise, participating units will practice unit-level mine warfare tactics to include sweeping, hunting, and mine detection.

“Exercises like 3JA give us a chance to practice mine-warfare utilizing every tool in our toolbox from our aviation mine-hunters at Helicopter Mine Countermeasures Squadron 14 Detachment in Pohang, Korea, our explosive ordnance disposal divers operating from the Mine Countermeasures Ships,” said U.S. Navy Capt. Adrian Ragland, commodore of Mine Countermeasures Squadron Seven. “This full spectrum mine-warfare really tests our ability to work as a coordinated group alongside our JMSDF partners.”

The exercise will culminate in a combined phase in which U.S. and JMSDF will coordinate and communicate to clear a route for ships through a simulated minefield in one of the designated exercise areas.

“This time, we have the opportunity to work together with Royal Australian Navy and U.S. Navy same as we had done last year.” said Rear Adm. Shirane Tsutomu, Commander Mine Warfare Force. “In this exercise, we plan SMCM, AMCM, and EOD team exercise. The aim of this exercise is to enhance the interoperability among all participants and improve the mine countermeasure skill. I am convinced that the Mine Counter Measures ability is essential for all participating countries to ensure the safety of marine traffic, and the effort which we achieve will contribute to the stability of Indo-Pacific Region. I sincerely hope that this mine warfare exercise will end in success and all participants will gain good results.”

JMSDF units will include Mine Warfare Force (MWF) and 19 ships including minesweeper tender, minesweeper ocean, minesweeper coastal and minesweeping controller ships. Additionally, they will include three mine countermeasures helicopters (MCH) 101.

RAN units include HMAS Diamantina (M 86) and HMAS Gascoyne (M 85).

Participating U.S. Forces include staff from Mine Countermeasures Squadron (MCMRON) 7, USS Pioneer (MCM 9), Explosive Ordnance Disposal Mobile Unit (EODMU) Platoon 122, and Helicopter Mine Countermeasure Squadron (HM) 14, DET 2. Approximately 160 U.S. personnel are scheduled to participate.
