HMS L14

HMS L14 was a British L class submarine built by Vickers, Barrow. She was laid down on 19 January 1917 and was commissioned on an unknown date.

HMS L14 was one of the several Group Two L class submarines to be built as a minelayer, carrying 16 mines. This meant that the two beam torpedo tubes were removed.

HMS L14 was sold in May 1934 in Newport.

The periscope from L14 is preserved at the Royal Navy Submarine Museum at Gosport. It may be the only surviving example of a World War I periscope. It was manufactured by Grubb & Co. in 1918.
