HMS R3 was an R Class, early 'Hunter-Killer' submarine built for the Royal Navy right at the end of the First World War.
HMS R3 was laid down on No 7 slip on 4th February 1917 and was launched by Mrs Silver into the Medway on 8th June 1918. She commissioned at Chatham on 17th March 1919.
On completion, she was 163 feet long and 16 feet wide across the beam. She was armed with 6 18" torpedo tubes, all in the bow. She displaced 420 tons on the surface and 500 tons dived. She was manned by a crew of 22.
On commissioning, she was sent to join 14th Submarine Flotilla at Blyth, attached to the depot ship HMS Vulcan.
She came too late to see any combat in World War I, like most of the other R class submarines. R3 was paid off in September 1919, then sold on 21 February 1923.
