US Fifth Fleet

The US Fifth Fleet is the US Navy formation permanently assigned to the Middle East, headquartered at Naval Support Activity Bahrain and reporting through CENTCOM. It holds operational command over the Persian Gulf, Red Sea, Gulf of Oman, and Arabian Sea, making Bahrain the centre of American naval power projection in the region and a recurring Iranian target. Since the war opened on 28 February 2026 the fleet has been the execution Arm of the Hormuz blockade, sustaining Iranian missile and drone campaigns throughout: 234 projectiles were intercepted in the first nine days, including a direct strike on the Fifth Fleet headquarters on 5 March. The USS Spruance intercepted the Iranian-flagged cargo ship Touska on 19 April 2026, and the Macron-Starmer joint statement of 20 April formalised a 51-nation Northwood Coalition that gave the fleet a multilateral umbrella.

By 3 June 2026, Bahrain's stock of Patriot Advanced Capability-3 interceptors was an estimated 87% depleted, leaving roughly eight rounds before that day's IRGC barrage. Bahrain had been excluded from Rubio's 2 May emergency resupply authorisation; a 1 June Federal Register notice added 50 PAC-3 MSE rounds on an 18-month procurement timeline, too slow to matter operationally. On the night of 5-6 June 2026 the IRGC fired seven Ballistic Missiles in a simultaneous salvo at US bases in both Kuwait and Bahrain, the largest two-country launch of the war; CENTCOM intercepted six of the seven.

On 9-10 June, the fleet's subordinate Task Force 59 executed the first unmanned-vessel personnel rescue in real-world combat: a Saronic Corsair USV recovered both crew of a downed AH-64 Apache near Hormuz within approximately two hours. Hours later the IRGC struck the Fifth Fleet headquarters in retaliation, the second direct attack on the base. Air defences engaged; no confirmed damage was reported. On 28 June 2026 the IRGC struck the headquarters for a third time in a coordinated attack that simultaneously targeted Ali Al Salem Air Base in Kuwait. The IRGC claimed eight targets struck across both facilities; US officials denied confirmed damage. A verbal stand-down was announced the following day, though no formal instrument was signed, leaving the fleet's force-protection posture unchanged against an adversary that has struck its headquarters three times since March.
