Guam is currently home to two (2) branches of service, the U.S. Navy and the U.S. Air Force.

In 2009, The Naval Base Guam, along with Andersen Air force Base was placed under the command of Joint Region Marianas (JRM), which was established in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. Based on the most recent reports from the Commander Naval Forces Marianas, also known as Comnavmarianas, Guam is home to 12,807 Military members and their dependents.

The U.S. Air Force hosts a rotating presence of bomber, tanker and fighter aircraft under the 36th Wing along with a variety of aircraft and contingency response training events. The U.S. Navy is home of Commander Submarine Squadron 15, Coast Guard Sector Guam and Naval Special Warfare Unite one and supports 28 other tenant commands. It is the home base of dozens of Pacific Command, United States Pacific Fleet, Seventh Fleet, and Seabee units. Units of Submarine Squadron 15 stationed at Guam include USS Chicago, USS Key West, USS Oklahoma City, and USS Topeka.

A large part of Guam’s economy is fueled by U.S. Military spending. The Department of Defense (DOD) continues to build Guam’s defense infrastructure capacity and is expected to accelerate with preparation for the Marine Corps relocation from Okinawa, Japan. During the last decade, DOD construction contracts have totaled over $2 billion and have averaged nearly $240 million annually for the most recent years. In 2016, the House Armed Services Committee (HASC) passed fiscal year 2017 National Defense Authorization Act (NDAA) that appropriated $253.858 million for military construction for Guam.
