RIMPAC

RIMPAC, short for Rim of the Pacific Exercise, is the world's largest international maritime warfare exercise. RIMPAC is held biennially (every two years) in June and July in Honolulu, Hawaii. Hosted and administered by the United States Navy's Indo-Pacific Command, it is a multinational training exercise intended to enhance interoperability among participating nations, ensuring the safety of sea lanes and security on the world's oceans.

The exercise typically involves a large number of ships, submarines, aircraft, and personnel from various countries. Activities conducted during RIMPAC include amphibious operations, gunnery, missile, anti-submarine, and air defense exercises, as well as mine clearance operations, explosive ordnance disposal, and maritime interception operations. Humanitarian assistance and disaster relief scenarios are also often incorporated.

RIMPAC's objectives are to foster and sustain cooperative relationships critical to ensuring the safety of sea lanes and security on the world’s oceans. It provides a unique training opportunity that helps participants improve their abilities to operate together in a wide range of maritime missions. The exercise also serves as a platform for participating nations to showcase their military capabilities and technological advancements.

Participation varies from year to year, but typically includes nations from the Pacific Rim, such as Australia, Canada, Chile, Japan, Malaysia, New Zealand, Peru, the Republic of Korea, Singapore, the United Kingdom, and the United States. Other nations from outside the Pacific region have also participated in the past.

RIMPAC contributes to regional stability and promotes a rules-based international order in the Indo-Pacific region.
