Base History & Name

Service members, families, retirees, and veterans gathered at the installation’s Community Club, May 1, to participate in the National Prayer Luncheon, where they prayed for peace and unity in Puerto Rico, the United States, and around the world.

Fort Buchanan is the only active U.S. Army installation in the Caribbean. Established in 1923, it was designed to support Army operations in Puerto Rico and the surrounding region.

The original mission emphasized logistical support, training, and administrative functions for U.S. military activities on the island. These core duties helped shape the base’s early development and importance.

During World War II, Fort Buchanan expanded rapidly to meet new demands. The base became a key staging and supply point for U.S. forces operating in the Caribbean and Latin America.

It supported anti-submarine operations and regional defense, hosting a variety of Army and Army Air Forces units. The installation’s infrastructure grew to accommodate thousands of troops and support personnel.

After the war, Fort Buchanan’s mission shifted to meet changing military needs. The base transitioned into a support and administrative hub for Army Reserve, National Guard, and other Department of Defense activities in Puerto Rico and the Virgin Islands.

It played a vital role during the Cold War by providing logistical and training support for U.S. forces in the region. This support helped maintain military readiness throughout the Caribbean.

Today, Fort Buchanan serves as the headquarters for the U.S. Army Reserve in Puerto Rico. The base supports thousands of Reserve, National Guard, and civilian personnel.

It also acts as a community hub, offering services to military families and retirees. Since its establishment, Fort Buchanan has retained its original name, with no significant official name changes recorded.

Namesake

Fort Buchanan is named after Brigadier General James A. Buchanan, a U.S. Army engineer who served with distinction in the late 19th and early 20th centuries. He played a key role in military construction projects, including work in Puerto Rico following the Spanish-American War.

Buchanan's leadership and engineering expertise contributed to the development of critical military infrastructure on the island. The fort honors his legacy and lasting impact on U.S. Army operations in Puerto Rico.
