Artillery booms and demolition blasts will be part of the background noise on Oahu through Dec. 19, as the U.S. Army carries out routine training on island ranges. The exercises, centered on Schofield Barracks and the East Range, may be heard and even felt in surrounding neighborhoods, and officials are stressing that while it can get loud, there is no immediate danger to the public.
What's scheduled
In a Dec. 1 advisory, U.S. Army Garrison Hawaii laid out the December training calendar. East Range activity is scheduled from Dec. 1 through Dec. 19 and includes range and jungle tactics along with small-arms blank fire, generally running from 6 a.m. to 6 p.m. Aviation training and air assault school are also planned on select days.
The Army notice also lists artillery, mortar and demolitions live-fire training at Schofield Barracks on Dec. 9 and 10. During those live-fire days, operations may run from about 5 a.m. until midnight.
Noise, weather and safety
The advisory warns that overcast skies and southerly Kona winds can make the booms travel farther, increasing both noise and vibrations, and that the training does not signal an immediate threat, as noted by Spectrum News. The Army notes that exercises can occur during both daytime and nighttime hours and that all schedules are subject to change.
Residents who are startled by the noise are urged not to assume an emergency. Officials say community members should report only unusual events or activity that appears out of the ordinary to the proper authorities.
How to report concerns
Neighbors with questions or concerns can call the U.S. Army Hawaii Community Concern Line at (808) 787-1528 or email [email protected]. Responses are provided during regular business hours, 8 a.m. to 4 p.m., Monday through Friday, according to the U.S. Army Garrison Hawaii advisory.
The advisory also notes that residents can subscribe to receive these notices directly by emailing the public affairs address with “Subscribe Training” in the subject line. Officials remind the public to keep traffic and emergency numbers handy in case a training-related incident appears to pose a real threat outside of the scheduled activities.
Why this matters
Monthly training advisories are routine, yet access to large live-fire ranges in Hawaii remains politically and culturally sensitive. The Associated Press reported this summer that Army leaders are trying to speed negotiations over the Pohakuloa Training Area lease on the Big Island amid public opposition, a dispute that affects where and how the military can conduct live-fire training.
For Oahu residents, the takeaway is straightforward: expect periodic noise as units train to maintain readiness, and use the Army’s contact line if anything seems off. The schedule is subject to change, and the Army has thanked the community for its understanding. For the latest details, residents are encouraged to check public affairs releases or call the community concern line during business hours.
