Ten nations, 22 ships, 1 submarine, and more than 5,300 personnel are participating in Exercise Rim of the Pacific from August 17 to 31 at sea around the Hawaiian Islands. RIMPAC is a biennial exercise designed to foster and sustain cooperative relationships, critical to ensuring the safety of sea lanes and security in support of a free and open Indo-Pacific region. The exercise is a unique training platform designed to enhance interoperability and strategic maritime partnerships. RIMPAC 2020 is the 27th exercise in the series that began in 1971.

JS Ise (DDH-182) is a Hyūga-class helicopter destroyer of the Japan Maritime Self-Defense Force (JMSDF). It is the second ship to be named Ise, the first being the Imperial Japanese Navy World War II-era battleship Ise. The Hyūgas are primarily anti-submarine warfare carriers operating SH-60K anti-submarine helicopters. They also have enhanced command-and-control capabilities to serve as flagships.

The Hyūga-class helicopter destroyer has a length of 197 m, 13,950t flat-deck vessel that can carry up to four helicopters on deck and operate 18 helicopters including SH-60K Seahawk anti-submarine helicopter and MCH-101 airborne mine countermeasure helicopter. The ship has a crew of 340 sailors and can only carry helicopters.

The Mitsubishi SH-60 series is a twin-turboshaft engine helicopter based on the Sikorsky S-70 helicopter family for use by the Japan Self-Defense Forces (JSDF). The SH-60K is an anti-submarine patrol version used by the Japan Maritime Self-Defense Force.

The AW101 is a medium-lift helicopter manufactured by the Italian company that was modified by Kawasaki Heavy Industries, and the Japan Defense Agency designated the model MCH-101. Special features include the automated folding of the rotor and tail. For the mine-hunting role, the MCH-101 has been outfitted with Northrop Grumman's AQS-24A airborne mine-hunting system and AN/AES-1 Airborne Laser Mine Detection System (ALMDS) for a complete surface-to-bottom mine detection capability, as well as Mk-104 acoustic minesweeping gear.

The Hyūga-class helicopter destroyer armament includes 16 cells Mk 41 VLS 'Vertical Launching System) able to fire RIM-162 Evolved SeaSparrow Missile used to protect ships from attacking missiles and aircraft, 12 RUM-139 VL ASROC anti-submarine missile, two 20 mm Phalanx CIWS (Close-In Weapon Systems), two triple 324 mm torpedo tubes and 12.7mm machine guns.
