Fort DeRussy Military Reservation

Fort DeRussy is a United States military reservation in the Waikiki area of Honolulu, Hawaii, under the jurisdiction of the United States Army. Unfenced and largely open to public traffic, the installation consists mainly of landscaped greenspace. The former Battery Randolph now houses the U.S. Army Museum of Hawaii, which is open to the public.

History
Fort DeRussy in Honolulu is one of five Forts DeRussy in the United States. The two in Louisiana, one in Kentucky, and one in Washington, D.C., were all built during the American Civil War. This one was named for General René Edward De Russy (1789–1865). Rene and his brother Lewis were both graduates of the United States Military Academy at West Point. Lewis was the oldest West Point graduate to serve in the Confederate Army, while older brother Rene served on the Union side.

Located on Waikiki Beach, very near Oahu's historic hotels the Royal Hawaiian Hotel and the Moana Hotel, the former Shore Battery Randolph was used as site for servicemen on Rest and Recuperation (R&R) during the Vietnam War. Fort DeRussy was one of a number of shore batterys on the island of Oahu designed to provide coastal defense. Most of the guns on these sites were retired during the early 1950s. The Fourteen inch guns of Shore Battery Randolph were fired once in a practice shortly after the Attack on Pearl Harbor, shattering many of the windows in the Royal Hawaiian and Moana, and were not fired again.

Active facilities
Official military functions include the Asia-Pacific Center for Security Studies, the Fort DeRussy Chapel, and the Hale Koa Hotel, a Morale, Welfare and Recreation facility.

U. S. Army Museum of Hawaii
The U.S. Army Museum of Hawaii is housed inside Battery Randolph, an old coastal artillery battery. Battery Randolph was constructed in 1911 to defend Honolulu Harbor on Oahu from attack, and was equipped with two 14-inch guns on disappearing carriages with a range of about 40000 yard. It was named for Maj Benjamin H. Randolph (died 1907).

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 exhibits cover the history of US Army warfare in the Pacific hemisphere and admission is free. It is located on Kalia Road, coordinates 21.27889°N, -157.83361°W.

Another installation of two 6-inch guns was called Battery Dudley, named for Gen. Edgar S. Dudley (died 1911). The "Artillery District of Honolulu" (state historic site 80-13-1382) was added to the National Register of Historic Places listings in Oahu on June 5, 1984.
