Joint Region Marianas' mission is to provide installation management support
to all Department of Defense components and tenants through assigned
regional installations on Guam and the Northern Mariana Islands in support
of training in the Marianas; to act as the interface between the Department
of Defense and the civilian community; to ensure compliance with all
environmental laws and regulations, safety procedures, and equal opportunity
policy; and perform other functions and tasks as may be assigned.
History
JRM was established by congressional legislation implementing the
recommendations of the 2005 Base Realignment and Closure Commission. The
legislation ordered the consolidation of facilities which were adjoining, but separate military installations, into a single joint base, one of 12 formed in the United States as a result of the law.
On February 6, 2009, the Navy and Air Force held a groundbreaking ceremony
for a combined headquarters at Nimitz Hill Annex. Joint Region Marianas
began initial operational capability on January 31, 2009, and reached full
operational capability on October 1, 2009.
A 2006 International Agreement between the US Government and the Government
of Japan directed a significant reduction in the number of Marines on
Okinawa. As part of that drawdown, the establishment of a Marine Corps Base
Guam was planned. In 2018, the Secretary of the Navy approved the renaming
of Marine Corps Base Guam in honor of the late Brigadier General Blaz. On 30
September 2020 the new base was activated as Marine Corps Base Camp Blaz. Installation management support is being provided under Joint Region Marianas. (MCBUL 5400 dtd 25FEB2020)
Under an agreement signed in November 2020, some installation support
functions were returned to Air Force to allow higher funding levels to meet
operational requirements. The agreement takes full effect on 1 October 2021.
Under Joint Region Marianas, Naval Base Guam (NBG), Andersen Air Force Base (AAFB) and Marine Corps Base Camp Blaz (MCB-CB) each maintain commanding officers, who will oversee their respective mission requirements and operations. Joint Region Marianas will oversee support services, policies, and resources for Navy and Marine Corps bases and some functions on AAFB. Air Force provides some support services to all Department of Defense components and tenants located on AAFB. Joint Region Marianas is located on Nimitz Hill between Naval Base Guam and Andersen AFB.
The commander of Joint Region Marianas also serves as Commander Naval Forces
Marianas and as U.S. Defense Representative to Guam, Commonwealth of the
Northern Mariana Islands, Republic of Palau, and Federated States of
Micronesia.
