United States Army Museum of Hawaii

The U.S. Army Museum of Hawaiʻi is housed inside Battery Randolph, a former coastal artillery battery, located at Fort DeRussy Military Reservation. The battery was transformed into a museum in 1976. The museum's collection contains some World War II armor pieces, an AH-1 Cobra helicopter, and small arms indoors, as well as the battery itself. The battery's main guns were scrapped prior to the inception of the museum.

Museum exhibits cover the military history of pre-Imperial Hawaii and the post-annexation history of US Army warfare in the Pacific hemisphere including World War II, Vietnam, and Korea. The museum also includes a "Gallery of Heroes" honoring recipients of the Medal of Honor and the Distinguished Service Cross.
