from the aircraft carrier , and her cruiser escort, . The action began with coordinated strikes by two surface groups. One surface action group, or SAG, consisting of the destroyers (including embarked LAMPS Mk I helicopter detachment HSL-35 Det 1 Helicopter Anti-Submarine Squadron Light 35) and , plus the amphibious transport dock and its embarked marine air-ground task force (Contingency MAGTF 2-88 from Camp LeJeune, NC) and the LAMPS helicopter detachment (HSL-44 Det 5) from USS Samuel B. Roberts, was ordered to destroy the guns and other military facilities on the Sassan oil platform. At 8 am, the SAG commander, who was also the commander of Destroyer Squadron 9, ordered the Merrill to radio a warning to the occupants of the platform, telling them to abandon it. The SAG waited 20 minutes, then opened fire. The oil platform fired back with twin-barrelled 23 mm ZU-23 guns. The SAG's guns eventually disabled some of the ZU-23s, and platform occupants radioed a request for a cease-fire. The SAG complied. After a tug carrying more personnel had cleared the area, the ships resumed exchanging fire with the remaining ZU-23s, and ultimately disabled them. Cobra helicopters completed the destruction of enemy resistance. The Marines boarded the platform and recovered a single wounded survivor (who was transported to Bahrain), some small arms, and intelligence. The Marines planted explosives, left the platform, and detonated them. The SAG was then ordered to proceed north to the Rakhsh oil platform to destroy it. As the SAG departed the Sassan oil field, two Iranian F-4s made an attack run but broke off when Lynde McCormick locked its fire-control radar on the aircraft. Halfway to the Rahksh oil platform, the attack was called off in an attempt to ease pressure on the Iranians and signal a desire for de-escalation. The other group, which included the guided missile cruiser and frigates and , attacked the Sirri oil platform. Navy SEALs were assigned to capture, occupy, and destroy the Sirri platform but because it had already been heavily damaged by naval gunfire, an assault was not required. Iran responded by dispatching Boghammar speedboats to attack various targets in the Persian Gulf, including the American-flagged supply ship Willie Tide, the Panamanian-flagged oil rig Scan Bay and the British tanker York Marine. All of these vessels were damaged in different degrees. After the attacks, A-6E Intruder aircraft launched from USS Enterprise were directed to
