HMS Slinger was an experimental catapult ship operated by the Royal Navy during the First World War.
A former hopper barge, HMS Slinger was purchased from the builder, Lobnitz and Company, Limited of Renfrew, Scotland prior to completion. Intended for use as a test bed for the shipborne launching of aircraft, she was fitted with a 60-foot compressed air catapult. HMS Slinger operated Fairey F.127 and Short 310 seaplanes during 1918.
Slinger was sold on October 16, 1919.
HMS Slinger has been the name of several Royal Navy vessels:
The USS Chatham (CVE-32) (originally designated AVG-32, then later ACV-32) was built at the Seattle-Tacoma S/Y, Hull #27, Seattle WA and transferred to the United Kingdom 11 August 1943 under lend-lease and renamed HMS Slinger (D26). Outfitted by the British as a transport carrier, the ship was mined on 5 February 1944 but returned to service, 17 October. In 1945, she was transferred for service in the Pacific as a fighter carrier. Following the war, she was returned to United States custody on 27 February 1946 and was sold/converted by Robin Line 21 November 1946 as Robin Mowbray. Moore-McCormack Lines, Inc purchased Robin Line in 1958. She was scrapped in Kaohsiung Taiwan in 1969-1970.
These ships were all larger and had a greater aircraft capacity than all the preceding American built escort carriers. They were also all laid down as escort carriers and not converted merchant ships. All the ships had a complement of 646 men and an overall length of 492 feet 3 inches (150.0 m), a beam of 69 feet 6 inches (21.2 m) and a draught of 25 ft 6 in (7.8 m). Propulsion was provided by one shaft, two boilers and a steam turbine giving 9,350 shaft horsepower (SHP), which could propel the ship at 16.5 knots (30.6 km/h; 19.0 mph).
