Background

US Fifth Fleet is the US Navy command responsible for operations in the Middle East. Based at Naval Support Activity Bahrain, it reports through US Central Command and covers The Persian Gulf, Red Sea, Gulf of Oman and Arabian Sea. Its REMIT makes Bahrain a command centre for US naval activity near the strait of Hormuz.

Reactivated in 1995, the fleet combines SEA control, maritime security and support for allied forces across waterways vital to Gulf trade. Its subordinate Task Force 59 develops and operates autonomous maritime systems, including the vessel used to recover two Apache crew members on 9 June.

The fleet's location gives Washington a permanent naval presence near Iran, but also makes its headquarters a direct target in a regional war. Iran struck the headquarters in Bahrain on 4 March, demonstrating that the command POST is exposed as well as operationally central.

US Fifth Fleet faces repeated strikes

On 3 June, Bahrain's Patriot interceptor stock was estimated to be 87% depleted before an Iranian barrage, exposing the US Fifth Fleet's headquarters to a shrinking defensive magazine. During the night of 5-6 June, the IRGC fired seven ballistic missiles at US bases in Bahrain and Kuwait; CENTCOM said it intercepted six.

For the US Fifth Fleet, the attacks made its home base part of the operational contest rather than a secure rear command. On 28 June, Iran again struck US facilities in Bahrain and Kuwait, while US officials reported no verified damage. The repeated attacks test whether the fleet can sustain regional naval operations while its host base remains within Iranian missile range.
