 During the 1991 Gulf War Sea Kings from several nations , including Canada , Britain , and the U.S. , were present in the coalition forces against Saddam Hussain 's Iraq regime . Due to the threat of potential use of any Iraqi weapons of mass destruction , it was standard practice for Sea King crews to wear fully enclosed NBC ( nuclear , biological , chemical ) protective suits . Britain 's Sea Kings primarily engaged in inter @-@ ship transport duties , including ferrying troops between the fleet and land . Six Sea King Mk4 helicopters from 845 Naval Air Squadron and six of 848 Squadron , which had been reformed to meet this operational demand , worked in support of the ground advance . There was thorough radar coverage by U.S. airborne early warning and control ( AWACS ) aircraft ; British AEW Sea Kings were not deployed .
