On 16 February 1991 a flight of B-52Gs launching from and returning to Barksdale AFB, in Louisiana, struck targets inside Iraq. This was at the time the longest distance combat mission in history: 35 hours and 14,000 statute miles round trip. Over the next months, B-52Gs operating from bases in the United Kingdom, Spain and on the island of Diego Garcia flew low level bombing missions. The B-52s moved to high level missions after Coalition forces ensured air superiority and were able to suppress air defense systems capable of reaching bombers at a higher altitude. B-52s were an important part of the air war during Operation Desert Storm as they could be employed with impunity. The conventional strikes were carried out by three bombers dropping 153 750 pound bombs at a time, covering an area one and a half miles long by one mile wide. The bombings demoralized the defending Iraqi troops, and they could be induced to surrender rather than be destroyed. Flying approximately 1620 sorties in the Gulf War, B-52s delivered 40% of the weapons dropped by coalition forces, while suffering only one aircraft loss, with several receiving minor damage from enemy action.
