The '''U and V class''' was a [[ship class|class]] of sixteen [[destroyer]]s of the [[Royal Navy]] launched in 1942–1943. They were constructed in two [[flotilla]]s, 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. The flotillas constituted the 7th Emergency Flotilla and 8th Emergency Flotilla, built under the War Emergency Programme. These ships used the [[Fuze Keeping Clock]] HA Fire Control Computer.<ref>{{cite book|title=Destroyer Weapons of World War II |last=Hodges |first=Peter |last2=Friedman |first2=Norman |publisher=Harper Collins |date=1979 |isbn=0-85177-137-8}}</ref>
