Other regular participants are Chile, Colombia, France, India, Indonesia, Japan, Malaysia, the Netherlands, Peru, Singapore, South Korea, and Thailand.

The Royal New Zealand Navy was frequently involved until the 1985 ANZUS nuclear ships dispute and was subsequently absent, until returning to take part in more recent RIMPACs since 2012.

While not contributing any ships, observer nations are involved in RIMPAC at the strategic level and use the opportunity to prepare for possible full participation in the future.

In the National Defense Authorization Act for Fiscal Year 2022, both houses of the US Congress have called for a Taiwanese participation of RIMPAC 2022 in the face of "increasingly coercive and aggressive behavior" by China.

The USS Nimitz carrier battle group, accompanied by at least one submarine as well as Japanese and Canadian Navy frigates and destroyers, were then sortied from Pearl Harbor in order to "rescue" Wombat from the aggressor force.

The much larger carrier battle group eventually "won" the exercise, as was expected, and peace loving "Wombat" was liberated.

[2] RIMPAC 1994 involved 57 vessels, and more than 200 aircraft from the United States, Japan, South Korea, Australia, and Canada each taking part in the exercise.

[7] During the exercise, the Independence's air wing (CVW-5) conducted war-at-sea strikes against the Kitty Hawk, with the support of Japanese and US vessels.

On 3 June 1996, an A-6E SWIP Intruder from VA-115 (NF-500, BuNo 155704) based on board the Independence was shot down around 1,600 miles (2,600 km) west of Hawaii by CWIS fire from JDS Yūgiri.

[12] On 23 June 2010, U.S. Pacific Fleet commander Admiral Patrick M. Walsh and Combined Task Force commander Vice Admiral Richard W. Hunt announced the official start of the month-long 2010 Rim of the Pacific (RIMPAC) exercise during a press conference held in Lockwood Hall at Joint Base Pearl Harbor–Hickam.

During the in-port phase of RIMPAC, officers and crew of the 14 participating navies interact in receptions, meetings, and athletic events.

[16] During 6–7 July 2010, 32 naval vessels and five submarines from seven nations departed Pearl Harbor to participate in Phase II of RIMPAC 2010.

[17] During RIMPAC 2010, over 40 naval personnel from Singapore, Japan, Australia, Chile, Peru, and Colombia managed combat exercises while serving aboard Ronald Reagan (pictured).

Tactical action officers from the different countries coordinated the overall operational picture and provided direction and administration to the enlisted personnel involved in the Sea Combat Control (SCC) activities.

[18] Also, Ronald Reagan conducted a live Rolling Airframe Missile (RAM) launch, firing at a simulated target, the first since 2007.

[15][16] On 30 July 2010, RIMPAC 2010 concluded with a press conference held at Merry Point Landing on Joint Base Pearl Harbor–Hickam.

[14] A reception for over 1,500 participants, distinguished visitors and special guests was held in the hangar bays of the carrier Ronald Reagan.

[21] On 17 July, USNS Henry J. Kaiser delivered 900,000 gallons of biofuel and traditional petroleum-based fuel to Nimitz's Carrier Strike Group 11.

[23][24] Russia participated actively for the first time,[25] as did the Philippines, reportedly due to the escalating tensions with the People's Republic of China over ownership of Scarborough Shoal.

The election of Chile as leader of the Task Groups is a recognition of the high performance achieved in recent editions and the quality of its personnel, which since its first participation in 1996 has been demonstrating its preparation and professionalism.

This appointment also places this country in a leadership position in the Latin American and world level in the planning and execution of combined naval operations.

[53] The Philippines sent its first missile-capable frigate on its maiden voyage, which was only commissioned into service 10 July 2020, as its "shakedown cruise" where its performance would be tested by the crew in the two-week exercises.

[55] These are the following navies that would take part in the exercise: On 29 August 2020, forces began firing on former USS Durham, a Charleston-class amphibious cargo vessel that was decommissioned in 1994.

The US Navy and partner nations wrapped up the biennial RIMPAC 2020 exercise over the weekend with the sinking of the decommissioned amphibious cargo vessel.

In RIMPAC 2000, for example, the first of the Strong Angel international humanitarian response demonstrations were held on the Big Island of Hawai'i near Pu'u Pa'a[where?].

For example, in 2004, the United States Navy tested the Australian-built HSV-2 Swift, a 321-foot (98 m) experimental wave-piercing catamaran that draws only 12 feet (3.7 m) of water, has a top speed of almost 50 knots (93 km/h; 58 mph), and can transport 605 tons of cargo.
