On September 18, 1965, an A-6A Intruder (bureau number 151588, call sign "Flying Ace 511") with two crew members launched from the aircraft carrier USS Independence (CVA 62) for a night bombing mission against enemy patrol boats in the Gulf of Tonkin. The Intruder was hit by anti-aircraft fire during the mission, and it crashed into the water and exploded. Extensive search and rescue efforts were mounted the next day, but failed to locate either crew member or any aircraft debris.

Commander Leonard Frederick Vogt Jr., who entered the U.S. Navy from Ohio, served with Attack Squadron 75. He was the pilot of this Intruder at the time of its loss. He remains unaccounted-for. Today, Commander Vogt is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
