NAVAL SUPPORT ACTIVITY BAHRAIN

OVERVIEW

Naval Support Activity Bahrain is the headquarters of U.S. Naval Forces Central Command (NAVCENT) and the U.S. 5th Fleet, the operational naval command responsible for U.S. maritime forces in the Persian Gulf, Red Sea, Gulf of Oman, and parts of the Indian Ocean. The installation sits in Juffair, a district of Manama, on the small island kingdom of Bahrain in the western Persian Gulf — within strategic reach of three of the world's most consequential maritime chokepoints: the Strait of Hormuz, the Bab el-Mandeb, and the Suez Canal approaches.

Approximately 9,000 U.S. service members, Department of the Navy civilians, contractors, and family members are assigned to the base, along with personnel from more than 38 partner nations of the Combined Maritime Forces (CMF). The CMF — headquartered alongside NAVCENT — coordinates the world's largest multinational naval partnership through Combined Task Forces 150 (maritime security), 151 (counter-piracy), 152 (Arabian Gulf security), and 153 (Red Sea and Bab el-Mandeb). In 2021, the Navy established Task Force 59 at NSA Bahrain as its first dedicated unmanned and artificial-intelligence integration task force, integrating maritime drones into routine fleet operations across the 5th Fleet area.

HISTORY

The U.S. Navy's presence in Bahrain dates to 1948, when the United States established the Middle East Force (MIDEASTFOR) under a tenant arrangement with the United Kingdom's Royal Navy at HMS Jufair, a small British base in Manama. Initially consisting of a single command ship and two supporting destroyers, MIDEASTFOR represented America's first peacetime naval presence in the Persian Gulf, established as Britain prepared to wind down its colonial role in the region.

When the United Kingdom withdrew from "east of Suez" in December 1971, the United States assumed the lease of HMS Jufair and renamed it Administrative Support Unit Bahrain (ASU Bahrain). For the next two decades the installation remained a modest logistics and command facility supporting MIDEASTFOR's standing presence, periodically reinforced during regional crises including the 1973 Arab–Israeli War, the 1979 Iranian Revolution, the 1980–1988 Iran–Iraq Tanker War, and the U.S. reflagging of Kuwaiti tankers under Operation Earnest Will.

The 1991 Gulf War transformed the installation. Operations Desert Shield and Desert Storm demonstrated the strategic indispensability of a permanent U.S. naval headquarters in the Gulf, and a new Defense Cooperation Agreement signed with Bahrain that year codified an expanded American military presence. In 1995, the U.S. Navy re-established the 5th Fleet — disbanded after World War II — at Bahrain, consolidating operational command of all U.S. naval forces between East Africa and Pakistan under a single three-star commander. The base was renamed Naval Support Activity Bahrain in 1999 and underwent rapid physical expansion, adding piers, headquarters buildings, family housing, schools, and a Defense Commissary.

Following the September 11, 2001 attacks, NSA Bahrain became the principal forward command node for U.S. naval operations in support of Operations Enduring Freedom and Iraqi Freedom, sustaining carrier strike groups operating in the North Arabian Sea and Persian Gulf. In 2002, the United States formally designated Bahrain a Major Non-NATO Ally — a status held by only a small group of close partners — recognizing the kingdom's central role in regional security.

The Combined Maritime Forces, also headquartered at NSA Bahrain, has grown to encompass more than three dozen partner nations and four numbered task forces conducting routine counter-piracy, counter-narcotics, and freedom-of-navigation operations across more than 3.2 million square miles of international water. In 2021, NAVCENT stood up Task Force 59 at NSA Bahrain — the Navy's first task force focused on integrating unmanned surface, subsurface, and aerial vehicles with artificial intelligence into fleet operations. Today NSA Bahrain remains the indispensable hub of U.S. maritime presence between the Suez Canal and the Strait of Malacca.

LOCATION & GEOGRAPHY

HOST NATION CONTEXT

U.S. forces in the Kingdom of Bahrain operate under a bilateral Defense Cooperation Agreement (DCA) signed in 1991 in the aftermath of Operation Desert Storm and renewed periodically since. The DCA governs U.S. access, status of personnel, and use of facilities. In 2002, the United States designated Bahrain a Major Non-NATO Ally (MNNA), placing it among a small group of countries with the closest non-treaty defense relationships with the U.S.

Bahrain is a constitutional monarchy ruled by the Al Khalifa family and a member of the Gulf Cooperation Council. The kingdom hosts the only permanent U.S. naval fleet headquarters in the Middle East and provides berthing access for U.S. and partner-nation warships at the adjacent Bahrain Defense Force port at Mina Salman.

U.S. service members and SOFA-status dependents enter Bahrain with no-fee official passports and a residence permit issued under the DCA; tourists and short-term visitors hold standard Bahraini eVisas or visas-on-arrival. Civilian visitors must be sponsored for base entry by a DoD-affiliated host.
