Delta Force was created in 1977 by Colonel Charles Beckwith. During an officer exchange program, Colonel Beckwith was trained and served in the British SAS from 1961-1962. This gave Delta Force the advantage to gain knowledge of the many skills that the British SAS are trained with.
In 1980, Delta Force took part in a mission, Operation Eagle Claw, which was initiated to rescue American hostages from the U.S. Embassy in Tehran. Sadly, the attempted mission failed due to an excessively multifaceted plan, and insufficient Special Operations Aviation training for assisting aircrews. Additional causes for failure of the mission were many mechanical problems of the fleet of eight helicopters, reducing the fleet to only five, which is one less than the minimum requirement and a collision with a rescue helicopter and a refueling tanker aircraft. This left the refueling site vulnerable to attack from the enemy.
Following the catastrophe, the 160th Special Operations Aviation Regiment (Airborne), additional known as the “Nightstalkers,” was created and given the responsibility of the transportation of all Special Forces personnel to and from all areas of operations.
