The British V-class submarine (officially "U-Class Long hull 1941–42 programme") was a class of submarines built for the Royal Navy during the Second World War.^[1]

Forty-two vessels were ordered to this design, all to be built by Vickers-Armstrong at either Barrow-in-Furness or at Walker-on-Tyne, but only 22 were completed. Note that seven of these vessels received 'U' names (conversely, four of the U class had received names beginning with 'V').

The V-class submarines were very similar to the preceding U-class (short-hull) boats, of which they constituted a linear development, but had 3⁄4-inch (19 mm) pressure hull plating instead of 1⁄2-inch (13 mm) for deeper diving, also a lengthened stern and fining at the bow to reduce noise and improve underwater handling.

They were sometimes referred to as Vampire-class submarines after HMS Vampire.^[2]

It was one of this class, HMS Venturer, that is the only submarine to sink another submarine while submerged - that submarine was the German U-864.

The vessels which were ordered are shown below in their programme order (not all completed construction):

The first eight vessels were ordered on 5 December 1941 under that year's programme.

• HMS Venturer (P68)
• HMS Viking (P69)
• HMS Veldt (P71), completed as Pipinos (Y8)
• HMS Vampire (P72)
• HMS Vox (P73)
• HMS Vigorous (P74)
• HMS Virtue (P75)
• HMS Visigoth (P76)

The next eighteen vessels were ordered on 21 May 1942 under that year's programme, but six of these were cancelled in early 1944.

• HMS Vivid (P77)

A further six vessels were ordered on 17 November 1942 under the same year's programme, but four of these were cancelled on 23 January 1944.

• HMS Votary (P29)
• HMS Vagabond (P18)
