2131 Kalia Rd
Honolulu, HI 96815
The U.S. Army Museum of Hawaii is open Tues - Sat from 10 AM - 5 PM. We are closed on Federal Holidays (if Holiday falls on a Monday then we are closed that Tuesday). The Museum is FREE to all with exhibits located on the first and second floor of the facility. Parking is available directly across the street from the museum in the Saratoga parking lot. Validation is available at the welcome desk. Constructed from 1909-11, the Coast Artillery Battery (known as Battery Randolph) protected Oahu with its two 14-inch disappearing guns. In the early 70’s, attempts were made to tear down Battery Randolph to make way for the Hale Koa Hotel, however, those attempts proved to be unsuccessful. In 1976, the structure was repurposed into a museum focusing on depicting early Hawaiian warfare and the military’s presence in the Pacific highlighting every major military encounter throughout the 20th Century.
