by flying into heavy enemy antiaircraft fire. His F-105 was severely damaged, but he determined the aircraft could still fly. Despite his nearly crippled plane, Dethlefsen made repeated strikes with his wingman, Kenneth Bell, against the enemy's defensive positions. Evading a second MiG, Dethlefsen dove through the obscuring haze to locate the missile complex when he was again hit by flak. Making a final dive bombing attack and a strafing run with 20 mm cannon fires, Dethlefsen effectively destroyed two missile sites before finally leaving for Takhli, 500 miles away. The mission was considered a success although two F-4s of the strike force were shot down.Chris Hobson, ''Vietnam Air Losses'', Midland Publishing, 2001 Dethlefsen could have pulled out of the mission on a number of occasions: when attacked by MiGs, when he and his wingman were hit by flak, or when the smoke of battle made it difficult to locate the enemy. But he decided to make repeated passes, each one more dangerous than the one before. For his actions, Dethlefsen was awarded the

s immediately after the strike by Maj. Dethlefsen's flight. In the initial attack on the defensive complex the lead aircraft was crippled, and Maj. Dethlefsen's aircraft was extensively damaged by the intense enemy fire. Realizing that the success of the impending fighter bomber attack on the center now depended on his ability to effectively suppress the defensive fire, Maj. Dethlefsen ignored the enemy's overwhelming firepower and the damage to his aircraft and pressed his attack. Despite a continuing hail of antiaircraft fire, deadly surface-to-air missiles, and counterattacks by

interceptors, Maj. Dethlefsen flew repeated close range strikes to silence the enemy defensive positions with bombs and cannon fire. His action in rendering ineffective the defensive SAM and antiaircraft artillery sites enabled the ensuing fighter bombers to strike successfully the important industrial target without loss or damage to their aircraft, thereby appreciably reducing the enemy's ability to provide essential war material. Maj. Dethlefsen's consummate skill and selfless dedication to this significant mission were in keeping with the highest traditions of the U.S. Air Force and reflect great credit upon himself and the Armed Forces of his country.
