BARKING SANDS — Live fire from aircraft, a submarine and land assets participating in the Rim of the Pacific exercise sank the decommissioned ex-USS Racine (LST-1191) July 12 in waters 15,000 feet deep 55 nautical miles north of Kauai.
Units from Australia, Japan, and the U.S. participated in the sinking exercise, which provided them the opportunity to gain proficiency in tactics, targeting and live firing against a surface target at sea.
“Today, we demonstrated the lethality and adaptability of our joint forces in the maritime environment,” said Adm. Phil Davidson, Commander, U.S. Indo-Pacific Command. “As naval forces drive our enemies into the littorals, army forces can strike them. Conversely, when the army drives our enemies out to sea naval firepower can do the same.”
The SINKEX featured live firing of surface-to-ship missiles by the Japan Ground Self-Defense Force and a Naval Strike Missile (NSM) from a launcher on the back of a Palletized Load System (PLS) by the U.S. Army. This marks the first time a land-based unit has participated in the live-fire event during RIMPAC.
This year was also the first time a Royal Australian Air Force P-8A Poseidon aircraft has participated in a SINKEX during RIMPAC.
“With numerous warships, allied submarines, multiple strike aircraft and multi-domain land forces participating, this SINKEX was an extremely valuable part of RIMPAC,” said Royal Canadian Navy Rear Adm. Bob Auchterlonie, deputy commander of the RIMPAC Combined Task Force. “SINKEXs are an important way for us to test our weapons and weapons systems in a way that provides our ships’ companies, our submariners, our aircrews, and our land forces with the most realistic training possible.”
Former U.S. Navy vessels used in SINKEXs, referred to as hulks, are prepared in strict compliance with regulations prescribed and enforced by the Environmental Protection Agency under a general permit the U.S. Navy holds pursuant to the Marine Protection, Research and Sanctuaries Act.
Each SINKEX is required to sink the hulk in at least 6,000 feet of water and at least 50 nautical miles from land. Surveys are conducted to ensure that people and marine mammals are not in an area where they could be harmed during the event.
Prior to the vessel being transported for participation in a SINKEX, each vessel is put through a rigorous cleaning process.
