RIMPAC 2026 multinational naval exercise – final phase
Overview
RIMPAC 2026 continued its wide‑range activities through late July. After Canada’s HMCS Ottawa fired a training torpedo on 7 July and U.S. medical units ran a mass‑casualty drill on 9 July, the exercise saw further milestones. India took over as Deputy Commander of the task force for theatre‑level anti‑submarine warfare on 13 July, reinforcing its ASW leadership. Indonesia’s Marine Corps added 105 mm howitzer firings in West Java and a non‑commissioned officer course in Hawaii, broadening the training mix. In the second week of July, U.S. forces conducted two live‑fire sinking exercises: the decommissioned cruiser USS Mobile Bay was struck on 12 July and the amphibious assault ship USS Peleliu on 17 July. Both vessels were sunk in waters about 15,000 ft deep, roughly 50 nm north of Kauai, using a variety of weapons from HIMARS rockets to Japanese Type‑12 anti‑ship missiles, AGM‑158C LRASMs and Rafael Spike NLOS missiles. The sinkings involved more than 30 000 personnel, 30 ships, five submarines and over 190 aircraft from the United States, Canada, Australia, Italy, Japan, New Zealand and Spain, providing realistic coalition targeting and execution training. The final phase wrapped up on 31 July after five weeks of multinational training around Hawaii. Over 30 nations fielded more than 30 000 service members, 31 surface ships, five submarines and roughly 190 aircraft. Vice Admiral Jeffrey T. Jablon highlighted the drill’s role in strengthening collective capability and deterring aggression, while Japan’s Rear Admiral Takuo Kobayashi stressed gains in anti‑submarine warfare and integrated air defence. Canada contributed two frigates (HMCS Regina and HMCS Ottawa), the submarine HMCS Corner Brook, motor vessel MV Asterix, CP‑140 Aurora patrol aircraft and CH‑148 Cyclone helicopters, deploying about 800 personnel.
