History Hour: First jet landing on aircraft carrier
The first landing and takeoff aboard an aircraft carrier by a jet-powered aircraft were made on the 3rd of December 1945 by Lieutenant-Commander Eric Melrose Brown, while flying a de Havilland DH.100 Sea Vampire Mk.10, LZ551/G. The ship was the Royal Navy Colossus-class light aircraft carrier, HMS Ocean (R68), under the command of Captain Casper John, RN.
For his actions in these tests, Lieutenant-Commander Brown was invested an Officer of the Most Excellent Order of the British Empire (OBE), 19 February 1946.
LZ551 was the second of three prototype DH.100 Vampires, which first flew on 17 March 1944. The airplane was used for flight testing and then in 1945, was modified for operation for carriers. It was named “Sea Vampire” and reclassified as Mk.10.
The DH.100 was a single-seat, single-engine fighter powered by a turbojet engine. The twin tail boom configuration of the airplane was intended to allow a short exhaust tract for the engine, reducing power loss in the early jet engines available at the time.
LZ551/G was originally powered by a Halford H.1 turbojet which produced 2,300 pounds of thrust (10.231 kilonewtons) at 9,300 r.p.m. This engine was produced by de Havilland and named Goblin.
The Vampire entered service with the Royal Air Force in 1945 and remained a front-line fighter until 1953. 3,268 DH.100s were built. There were two prototype Sea Vampires (including LZ551) followed by 18 production Sea Vampire FB.5 fighter bombers and 73 Sea Vampire T.22 two-place trainers.
HMS Ocean was built at the Alexander Stephen and Sons yard on the Clyde, Glasgow, Scotland. The ship was launched in 1944 and commissioned 8 August 1945. Classed as a light fleet carrier, HMS Ocean was 630 feet (192 meters) long at the water line, with a beam of 80 feet, 1 inch (24.41 meters) and standard draft of 18 feet, 6 inches (5.64 meters) at 13,190 tons displacement; 23 feet, 3 inches (7.09 meters), at full load displacement (18,000 tons). The aircraft carrier’s flight deck was 695 feet, 6 inches (212.0 meters) long. Ocean was driven by four Parsons geared steam turbines producing 40,000 shaft horsepower, and had a maximum speed of 25 knots (28.8 miles per hour/46.3 kilometers per hour). HMS Ocean had a crew of 1,050 sailors, and could carry 52 aircraft.
HMS Ocean served for twelve years before being placed in reserve. Five years later, she was scrapped at Faslane, Scotland.
