When the Gulf Crisis of 1990 was triggered by the Iraqi invasion of Kuwait, the RAF responded by sending Tornado F 3 fighters to Saudi Arabia to help defend the country against further aggression. These aircraft were followed by the deployment of Tornado GR 1 strike/attack aircraft to Bahrain. Eventually three wings of Tornado GR 1s were established in Bahrain, Tabuk and Dhahran, as well as a detachment of Tornado GR 1A reconnaissance aircraft. At the start of hostilities in January 1991, the Tornado GR 1 wings carried out night-low-level attacks against Iraqi Main Operating Bases using the JP233 runway denial weapon. Meanwhile, Combat Air Patrols from the Tornado F 3 wing ensured the integrity of Saudi airspace.
