The President of the United States of America, authorized by Title 10, Section 8742, United States Code, takes pride in presenting the Air Force Cross (Posthumously) to First Lieutenant Karl Wendell Richter (AFSN: 0-78872), United States Air Force, for extraordinary heroism in military operations against an opposing armed force while serving with the 421st Tactical Fighter Squadron, 388th Tactical Fighter Wing, Korat Royal Thai Air Base, Thailand, as the leader of a flight of F-105s on a mission over North Vietnam on 20 April 1967. The target, a very important railroad facility, was defended by several hundred anti-aircraft artillery emplacement and SA-2 missiles. Lieutenant Richter’s mission was to destroy or limit fire from these defenses immediately before a strike on this facility by fighter bombers. Arriving over the approach to the target, he found clouds obscuring navigational references and increasing the danger from unobserved SAM launches. Despite weather conditions, Lieutenant Richter, with great professional skill and undaunted determination, led his flight through a barrage of missiles to the target. Braving the heavy concentrated fire of the anti-aircraft artillery, he positioned his flight and attacked the defenses, causing heavy damage. As a result of his efforts, the fighter bombers of the main strike force encountered only limited defensive fire and destroyed this vital railroad facility. Through his extraordinary heroism, superb airmanship, and aggressiveness in the face of hostile forces, First Lieutenant Richter reflected the highest credit upon himself and the United States Air Force.
