HMS Storm was an S-class submarine of the Royal Navy, and part of the third group built of that class. She was built by Cammell Laird and launched on 18 May 1943. So far, she is the only RN ship to bear the name Storm. She served in the Far East, from Trincomalee in modern Sri Lanka and from Perth, Australia. She was notable for being the first operational submarine to be commanded by a British officer from the Royal Naval Volunteer Reserve, Commander Edward Young, DSO, DSC and bar (he had previously commanded the P555 which was used in the training of crews and anti submarine ships).
