Lieutenant Commander Edward Henry O'Hare was an American naval aviator of the United States Navy, who on February 20, 1942, became the Navy's first fighter ace of the war when he single-handedly attacked a formation of nine medium bombers approaching his aircraft carrier. Even though he had a limited amount of ammunition, he was credited with shooting down five enemy bombers and became the first naval aviator recipient of the Medal of Honor in World War II.

The Grumman F6F Hellcat is an American carrier-based fighter aircraft of World War II. Designed to replace the earlier F4F Wildcat and to counter the Japanese Mitsubishi A6M Zero, it was the United States Navy's dominant fighter in the second half of the Pacific War. In gaining that role, it prevailed over its faster competitor, the Vought F4U Corsair, which initially had problems with visibility and carrier landings.
