Royal Navy unit history places 846 Naval Air Squadron in Operation Desert Storm and states that the squadron helped secure Kuwait's liberation. The same history identifies 846 NAS as equipped with Sea King Mk4 helicopters before its 1982 Falklands deployment and later describes the squadron's Sea King use in other expeditionary operations.
A squadron-history database gives the most specific Gulf War Sea King entry for 848 Naval Air Squadron: it says 848 NAS reformed at Yeovilton on November 16, 1990 with six Sea King HC.4 helicopters and served in Operations Desert Shield and Desert Storm in the Middle East.

Timeline
The Sea King HC.4 presence was part of the British contribution to the U.S.-led coalition campaign that followed Iraq's August 2, 1990 invasion and occupation of Kuwait. 848 NAS was reformed in November 1990 for the Gulf deployment, operated through Desert Shield and Desert Storm, and returned to Britain after the fighting.
The coalition ground offensive began on February 24, 1991 and Kuwait was liberated before offensive operations ceased on February 28. Secondary Sea King histories describe British Sea Kings in this period as transport and support aircraft rather than strike or airborne early-warning platforms.

Narrative
In Gulf War service, the Westland Sea King evidence points to commando support and mobility work. Royal Navy 846 NAS records its participation in Operation Desert Storm, while 848 NAS was reactivated specifically for the crisis with Sea King HC.4 helicopters. The documented role is coalition support, not independent attack or air-defense activity.
Sea King HC.4 aircraft were troop- and utility-transport helicopters in Royal Navy Commando Helicopter Force service. Secondary summaries of the Gulf War deployment describe British Sea Kings as ferrying personnel between ships and land and supporting the ground advance, while noting that British airborne early-warning Sea Kings were not deployed because coalition radar coverage came from U.S. AWACS aircraft.
The sources do not support a precise public sortie count, individual aircraft list, or named landing zone for Sea King Gulf War operations. The source-backed record is that Royal Navy Sea King HC.4 helicopters were fielded by coalition forces during Desert Shield and Desert Storm for battlefield support, transport, and logistics.
