They were constructed in two flotillas, each with names beginning with "U-" or "V-" (although there was a return to the pre-war practice of naming the designated flotilla leader after a famous naval figure from history to honour the lost ships Grenville and Hardy).

The hull was nearly identical to the preceding ships of the S and T classes, but the U and V class ships had different bridge and armament fits.

These ships used the Fuze Keeping Clock HA Fire Control Computer.
