  HMS Slinger was an experimental catapult ship operated by the Royal Navy during the First World War. After Royal Navy service from 1917 to 1919, she operated as a commercial cargo ship under the names SS Niki and SS Lingfield from 1920 until she sank in 1941.
  
  ## Royal Navy service
  
  Constructed as a hopper barge, HMS Slinger was purchased from her builder, Lobnitz and Company, Limited of Renfrew, Scotland, prior to completion. Intending to use her as a test bed for the shipborne launching of aircraft, the Royal Navy fitted her with a 60-foot (18.25-meter) compressed air catapult. HMS Slinger operated Fairey F.127 and Short 310 seaplanes during 1918.
  
  Slinger was sold on 16 October 1919.
