The Strange Fighter That Killed Without Seeing Its Targets

During the Korean War, the United States deployed one of the strangest-looking jet fighters ever built: the Douglas F3D Skyknight, a massive, straight-winged aircraft nicknamed “Willie the Whale.” While faster, swept-wing fighters dominated the skies, the Navy had designed the Skyknight for an entirely different mission: hunting enemy aircraft in complete darkness. Equipped with an advanced radar system, two crewmen sitting side by side, and four powerful 20-millimeter cannons, the F3D could locate and destroy enemy aircraft before its pilots ever saw them. Despite its bulky appearance and relatively slow speed, the Skyknight became a deadly night fighter over Korea, protecting American B-29 bombers from Soviet-built MiG-15 jets and even shooting down an enemy biplane without visual contact. By the end of the conflict, the Skyknight had achieved six confirmed aerial victories against only one air-to-air loss, proving that radar could be more important than speed in modern combat. But its career was far from over. After Korea, the aircraft helped test the Navy's early Sparrow guided missiles, before undergoing an extraordinary transformation into the EF-10B electronic warfare aircraft during the Vietnam War. Instead of using radar to find enemy fighters, these modified Skyknights carried sophisticated jamming equipment designed to disrupt North Vietnamese radar stations, anti-aircraft guns, and deadly SA-2 surface-to-air missiles. Flying dangerous missions alongside American strike aircraft, the aging jets became some of the Marine Corps' earliest airborne electronic warfare platforms, helping protect other aircraft from increasingly sophisticated air defenses. This is the incredible story of America's forgotten jet fighter, an aircraft that looked obsolete from the moment it was built but helped revolutionize aerial combat, from the first radar-guided night interceptions to the electronic warfare systems still used by modern military aircraft.
