Operation Northern Delay occurred on 26 March 2003 as part of the 2003 invasion of Iraq. It involved dropping paratroopers into Northern Iraq. It was the last large-scale combat parachute operation conducted by the U.S. military since Operation Just Cause. Background On 26 March 2003, during the 2003 invasion of Iraq, C-17s of the 62d Airlift Wing, 315th Airlift Wing, 437th Airlift Wing, and 446th Airlift Wing dropped SETAF's 173rd Airborne Brigade into Northern Iraq. 996 paratroopers jumped into the Bashur drop zone (). The operation forced the Iraqi Army to maintain approximately six divisions in the area to protect its northern flank, providing strategic relief for Coalition Forces advancing on Baghdad from the south. Bashur Airfield is located in northern Iraq approximately 356 kilometers North of Baghdad, 50 kilometers Northeast of Erbil. The airbase is served by a single 6,700 foot long runway. Bashur appeared to be a small civilian airport. Bashur is the epitome of a bare base. It was nothing more than a 7,000-foot runway in the middle of a green valley. It had no infrastructure - no water or sewage system and no electricity, buildings or paved roads. Operation On 26 March 2003, more than 950 paratroopers from the 173d Airborne Brigade jumped into Bashur, Iraq, to set the stage for a northern front. Two days later, the first soldier from the 501st Forward Support Company, 173d Airborne Brigade, Supply Support Activity (SSA) arrived at Bashur Airfield. The operation was classified as a combat jump by the Army, although the landing zone was secured by Kurdish and American forces. During the next two weeks at Bashur Airfield, all supplies arrived via the airlines of communication (ALOC) on C-17s and C-130s from Ramstein Air Base, Germany through Constanta Air Base, Romania. During an average 24-hour day of operations, more than 40 Air Force 463L ALOC pallets would arrive. Each pallet then had to be downloaded from the plane, transported to the SSA, processed and finally issued either to storage or to customers. Some of the C-17s carried huge M1-A Abrams tanks and weighed from 250,000 to 300,000 pounds when they landed. After two weeks of use by heavy cargo planes, parts of Bashur's 7,000-foot runway crumbled, forcing the closure of 2,300 feet. Aftermath As of April 2003, Delta Battery 319th Airborne Field Artillery Regiment remained in Bashur, and continued training the New Iraqi Army on key tasks
