DH.110 Sea Vixen

The de Havilland DH.110 Sea Vixen was a Royal Navy Fleet Air Arm all-weather fighter built around twin engines, twin booms, radar interception, and carrier operations. It represented the Royal Navy's move from gun-era jet fighters toward missile-armed fleet air defense during the early Cold War.

Sea Vixen combined a radar-equipped crew station with naval features such as folding wings, reinforced landing gear, catapult fittings, and an arrestor hook. Its mission was to intercept hostile aircraft before they threatened the fleet, especially in poor weather or low-visibility conditions where radar control mattered more than visual detection.

The aircraft's twin-boom layout and offset cockpit made it distinctive, while carrier operations made the design complex to fly and maintain. Sea Vixen is most useful historically as a bridge between early naval jets and later integrated air-defense systems that combined radar, missiles, and carrier-based fighters.
