FMF-PAC operated on Camp Catlin, Hawaii, until 1950 when the staff began looking for a more permanent location. In 1955, the command moved into the former Aiea Heights Naval Hospital that had completed constructed in 1942, with the first Marine residents taking post in October of 1955. The headquarters staff placed the camp in full operation just two weeks before its dedication on January 31, 1956.

In 1992, U.S. Marine Corps Forces, Pacific, was designated a service component headquarters, and the commander still maintains the role of FMF-PAC.

Since 1955, the commander, U.S. Marine Corps Forces, Pacific, leads, operates, and commands from the headquarters base, Camp H.M. Smith, Hawaii. The camp was named after Gen. Holland M. “Howlin’ Mad” Smith on June 8, 1955, in honor of his leadership during World War II, including leading Marines to victory in the island-hopping campaign across the Pacific, and for his successes in modernizing amphibious warfare.

Nimitz ordered all able patients to assemble in front of the hospital in order to personally present the combat-wounded patients their awards.

Following the September 11, 2001 attacks and the initiation of Operation Enduring Freedom, Lieutenant General Earl B. Hailston, Jr., commander, U.S. Marine Corps Forces, Pacific, was designated as commander, U.S. Marine Corps Forces, Central Command. Although tailored for operations in littoral environments, Lt. Gen. Hailston was tasked with establishing a Combined Joint Task Force-Consequence Management headquarters in Kuwait. Later, Lt. Gen. Hailston and his staff would oversee the deployment of more than 70,000 U.S. Marines and sailors to the CENTCOM AOR in support of Operation Iraqi Freedom.

In August of 2005, as the number of operations in the CENTCOM AOR increased, MARCENT was removed from the responsibilities of MARFORPAC and its commander, and a free standing headquarters was established as U.S. Marine Corps Forces, Central Command.

U.S. Marines in the Pacific are assigned to the commander, U.S. Indo-Pacific Command, and operate across the INDOPACOM area of responsibility that contains two-thirds of the world's population, 43 countries, the world's six largest armed forces and crosses 16 time zones – more than half the Earth's surface.
