HMS R4 was a British R class submarine built at Chatham Dockyard. She was laid down on 4 March 1917 and launched on 8 June 1918. R4 was commissioned on the 23 August 1919. She came too late to see any combat in World War I, like most of the other R class submarines. The submarine's shape resulted in her being nicknamed "The Slug".[1]
R4 was the only boat to survive through to the 1930s. Additions to her casing produced slightly better sea keeping at the cost of a reduced speed from 15 knots submerged to 13 knots. R4 was used as a fast underwater target at the Portland anti-submarine school until 1934, then sold on 26 May 1934 to Young, Sunderland.
