The President of the United States of America takes pleasure in presenting the Distinguished Flying Cross to Captain [then Commander] William Porter Lawrence (NSN: 0-543032), United States Navy, for heroism and extraordinary achievement while participating in aerial flight on 23 June 1967, while serving as Commanding Officer of Fighter Squadron ONE HUNDRED FORTY-THREE (VF-143), embarked in U.S.S. CONSTELLATION (CVA-64), during aerial combat operations in Southeast Asia. Captain Lawrence led a coordinated strike against the heavily defended railroad yard and thermal power plant at Nam Dinh, North Vietnam. He guided the strike group through a barrage of radar-directed anti-aircraft fire of all calibers, continuous surface-to-air missile radar tracking, and the threat of airborne enemy fighters. In addition to fulfilling his strike leader responsibilities, Captain Lawrence also served as navigational pathfinder and leader of the flak-suppression effort, personally silencing the multiple-gun emplacement which posed the primary threat to the force. Under his tactical leadership, and freed from the harassment of the intense enemy fire, the strike group inflicted extensive damage and destruction upon this important target. During the attack, Captain Lawrence positioned his section as Target Combat Air Patrol between the strike group and the enemy fighter threat, remaining on station to monitor bomb damage and element coordination until all other aircraft had safely retired. His airmanship, resourcefulness, and courageous dedication were in keeping with the highest traditions of the United States Naval Service.
