As the title says, are there any ships built before or during WW2 still in active service with any navy? I don't want to know about training ships (USCGC Eagle, HMS Caroline, etc.) or commissioned museum ships/memorials (e.g. Arizona), just active warships. The last ones I know of are the Brazilian carrier NAeL Minas Gerais (ex-HMS Vengeance, decommissioned 2001) and the Taiwanese Chao Yang destroyers (US Gearing class ships, of which the last went out of service in the late 2000s).
