Exercise RIMPAC

RIMPAC, the Rim of the Pacific Exercise, is the world's largest international maritime warfare exercise. RIMPAC is held biennially during June and July of even-numbered years from Honolulu, Hawaii. It is hosted and administered by the United States Navy's Pacific Fleet, headquartered at Pearl Harbor, in conjunction with the Marine Corps, the Coast Guard, and Hawaii National Guard forces under the control of the Governor of Hawaii. The US invites military forces from the Pacific Rim and beyond to participate. With RIMPAC the United States Pacific Command seeks to enhance interoperability between Pacific Rim armed forces, ostensibly as a means of promoting stability in the region to the benefit of all participating nations. Described by the US Navy as a unique training opportunity that helps participants foster and sustain the cooperative relationships that are critical to ensuring the safety of sea lanes and security on the world’s oceans.

Participants

The first RIMPAC, held in 1971, involved forces from Australia, Canada, New Zealand, the United Kingdom (UK), and the United States (US). Australia, Canada, and the US have participated in every RIMPAC since then. Other regular participants are Chile, Colombia, France, Indonesia, Japan, Malaysia, the Netherlands, Peru, Singapore, South Korea, Thailand, and the UK. The Royal New Zealand Navy was frequently involved until the 1985 ANZUS nuclear ships dispute, but has taken part in recent RIMPACs such as in 2012 and 2014.
