The British V class submarine (officially "U-Class Long hull 1941–42 program"[1]) was a class of submarines built for the Royal Navy during World War II. 42 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 7 of these vessels received 'U' names (conversely, 4 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" pressure hull plating instead of 1/2" for deeper diving, also a lengthened stern and fining at the bows to reduce noise and improve underwater handling.

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