The U.S. Army's 25th Infantry Division is leading the Joint Pacific Multinational Readiness Center exercise in Hawaii, which began October 28, 2026. Allies and partners from Singapore, the Republic of Korea, France, New Zealand, Japan, and the Maldives are participating.
Why it matters
The U.S. Military warns that residents across Hawaii may notice increased aircraft flights, vehicle activity, and noise during the exercise. The training is designed to enhance readiness and interoperability of U.S. forces and multinational partners in multi-domain operations.
The exercise involves about 7,000 personnel across an October 28 to November 17 window. Specific noise levels, flight counts, and the full scope of impacts on individual islands have not been detailed in available reporting.
The players
25th Infantry Division
The U.S. Army division is leading the Joint Pacific Multinational Readiness Center exercise in Hawaii, a unit based in the Pacific region with a long history of training for jungle and island warfare.
U.S. Air Force 15th Wing
The Air Force wing reports increased military aircraft, service vehicles, and personnel activity around Joint Base Pearl Harbor-Hickam during the exercise, and is based at the joint installation on Oahu.
The details
The training provides realistic, live, virtual, and constructive instruction in archipelagic, jungle, and arctic environments. The military is conducting activities in isolated training areas to limit disruption to the community, though residents on Oahu's North Shore, Wahiawa, and parts of Kauai and Hawaii Island may still notice the increased activity.
Timeline
October 28, 2026: JPMRC exercise begins.
November 2026: Residents may notice more noise and activity throughout the month.
Mid-November 2026: The last major exercise is scheduled.
November 17, 2026: JPMRC exercise ends.
Season Trajectory
The Joint Pacific Multinational Readiness Center, an ongoing Army training program, continues to bring allied forces to Hawaii for multi-domain readiness exercises. This iteration follows that established pattern, with partner participation from Singapore, the Republic of Korea, France, New Zealand, Japan, and the Maldives.
Residents on Oahu's North Shore, in Wahiawa, and on parts of Kauai and Hawaii Island may notice more aircraft, vehicle activity, and noise through November. Those with travel or daily plans in affected areas should expect the increased activity during the exercise window.
The takeaway
The exercise is a scheduled, time-limited training effort, so residents near affected areas can expect the increased activity to end after November 17, 2026. Staying informed through official military notices can help plan around periods of heightened noise and traffic.
What happens next
The last major exercise is scheduled for mid-November 2026, and the full JPMRC exercise concludes November 17, 2026.
