Rim of the Pacific

Exercise Rim of the Pacific (RIMPAC) is the world’s largest international maritime exercise comprised of nations with an interest in the Pacific Rim region. RIMPAC is conducted on a biennial basis from the Hawaiian Islands and Pearl Harbour.


RIMPAC provides an important training opportunity to:

  • enhance interoperability between participating forces;
  • improve readiness for a wide range of potential operations; and
  • strengthen military-to-military partnerships.

Canada’s objectives

Canada has participated in every RIMPAC since its inception in 1971. The biennial exercise provides an opportunity for all services (Canadian Army, Royal Canadian Navy and Royal Canadian Air Force) to train in a joint environment along with international allies and partners.

The joint forces deployed on RIMPAC comprise personnel and assets from across Canada, and may be drawn from any or all of the primary force-generators of the Canadian Armed Forces.

The CAF objectives during RIMPAC are to:

  • develop and implement plans to enable the army, navy and air force to operate as a joint force within a multinational coalition setting;
  • enhance the CAF’s ability to conduct international missions in accordance with the Government of Canada’s objectives; and
  • develop skills and procedures designed to foster operability, readiness, communications with partners and crisis response capabilities.


RIMPAC began in 1971 as an annual exercise. Since 1974, the exercise has been scheduled every second year. Canada, the United States and Australia are the only nations to have participated in every exercise since its inception.

Other nations that have participated in RIMPAC include: Chile, Colombia, France, India, Indonesia, Japan, Malaysia, Mexico, Netherlands, New Zealand, Norway, Peru, Philippines, Republic of Korea, Singapore, Thailand, Tonga, and the United Kingdom, among others.  

The area

The Pacific Rim region is a hub of international activity and has great importance for international commerce. The area itself is too large for any one nation to monitor and requires the ability of likeminded nations to work together to monitor the area and meet its unique challenges.

The Pacific Ocean remains an important area of Canadian interest – more Canadian trade occurs across the Pacific than across the Atlantic.

Exercise phases

RIMPAC takes place in three phases: Harbour, Force Integration Training and Free Play Phases. Each phase offers a different experience to learn and allows service members opportunities to assume a wide variety of leadership positions.

The Harbour Phase is designed to build professional and personal relationships between individuals from participating nations. Personnel have the opportunity to meet face-to-face for briefings, training and detailed planning. The aim is to allow participants to get to know their exercise colleagues, finalize details and lay the foundation for a successful and professional operating environment.  

The Force Integration Phase involves a structured and detailed training program aimed at enabling participants to operate at the task force level. It exercises each nation’s ability to operate in a robust and multinational command and control environment. This phase also includes:

  • live-fire gunnery and missile exercises;
  • maritime interdiction and vessel boarding exercises;
  • anti-surface warfare;
  • anti-submarine warfare;
  • underwater warfare and naval manoeuvre exercises;
  • air defence and amphibious landings exercises;
  • explosive ordinance disposal;
  • diving and salvage operations; and
  • mine clearance operations.

While the Force Integration Training Phase develops the skills of participating units, the Free Play Phase tests those skills during a scenario. Component commanders and subordinate units respond to increasingly intense scenarios, including realistic situations that nations could face in the Pacific Rim. As a result, participating units and personnel experience challenging full-spectrum operations that cover air, surface, submarine and land threats.
