The President of the United States of America takes pleasure in presenting a Third Gold Star in lieu of a Fourth Award of the Distinguished Flying Cross to Lieutenant Commander Robert B. Arnold, United States Navy, for heroism and extraordinary achievement in aerial flight as a jet attack pilot serving with Attack Squadron One Hundred Sixty-four embarked in U.S.S. Oriskany (CVA-34) on 26 October 1967. Lieutenant Commander Arnold was the leader of a division of surface-to-air missile suppression aircraft in support of a major strike against the Hanoi Thermal Power Plant. This primary source of power for the enemy’s capital city was fiercely defended by the most sophisticated array of anti-aircraft batteries and surface-to-air missile sites in all of North Vietnam. Lieutenant Commander Arnold distinguished himself by his meticulous preflight planning and attention to detail in positioning the available missile-suppression aircraft so as to provide maximum protection to the main strike force. He assigned each member of his flight a specific high threat occupied missile site to take under direct attack. Approaching the target area, Lieutenant Commander Arnold accelerated ahead of the main force, penetrated the enemy’s inner defenses and executed a daring attack on a high threat active missile site two miles to the east of Hanoi. He completed two successful attacks with his antiradar missiles in the face of intense, accurate anti-aircraft fire. His weapons were observed impacting in the radar vans and destroyed the critical missile guidance radar. While encountering heavy, accurate 85 and 57 millimeter anti-aircraft fire, he courageously repositioned himself for an attack on the missiles and launchers with his remaining bombs. In spite of the immediate danger to his own safety, he executed a precision attack and destroyed two launchers with missiles poised for firing. Lieutenant Commander Arnold’s thorough planning, professional leadership and aggressive execution of the demanding surface-to-air missile suppression role which resulted in the confirmed destruction of an active enemy missile site in the face of the fiercest enemy resistance made a significant contribution to the success of the primary mission. His heroic actions and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
