Town class destroyer

From Wikipedia, the free encyclopedia

The Town class destroyers were warships transferred from the United States Navy to the Royal Navy and the Royal Canadian Navy in exchange for military bases in the Bahamas and elsewhere, as outlined in the Destroyers for Bases Agreement between Britain and United States, signed on 2 September 1940. They were known as "four-pipers" or "four-stackers" because they had four smokestacks (later classes of destroyers typically had one or two).

Some went to the Royal Canadian Navy at the outset. Others went on to the Royal Norwegian Navy, the Royal Netherlands Navy, and the Soviet Navy after serving with the Royal Navy. Although given a set of names by the Commonwealth navies that suggested they were one class they actually came from three classes of destroyer: Caldwell, Clemson and Wickes.

Roughly contemporaneous to the British V and W class destroyers they were not much liked by their new crews. They were uncomfortable and wet, working badly in a seaway. Their hull lines were rather narrow and 'herring-gutted' which gave them a vicious roll. The officers didn't like the way they handled either, since they had been built with propellors that turned the same way (2-screw ships normally have the shafts turning in opposite directions as the direction of rotation has effects on the rudder and the whole ship when manoeuvring, especially when coming alongside), so these were as awkward to handle as single-screw ships. Their turning circle was enormous, as big as most Royal Navy battleships, making them difficult to use in a submarine hunt which demanded tight maneouvers, compounded by unreliable "chain and cog" steering gear laid across the main deck. They also had fully-enclosed bridges which caused problems with reflections in the glass at night.

The armament was four 4 inch (102 mm) guns. On the Wickes class, the placement was one gun in a shield on the forecastle, one on the quarterdeck and one each side on a platform between the number 2 and number 3 funnels.

Despite their disadvantages they performed vital duties escorting convoys in the Atlantic at a time when the U-boats, operating from newly-acquired bases on the Atlantic coast of France were becoming an increasingly serious threat to British shipping.

One of the Towns achieved lasting fame: HMS Campbeltown (ex-USS Buchanan). In the Commando raid Operation Chariot, Campbeltown, fitted with a large demolition charge, rammed the Normandie Lock at Saint-Nazaire, France. The charge detonated on 29 March 1942, breaching the drydock and destroying Campbeltown, thus destroying the only drydock on the Atlantic coast capable of accepting the German battleship Tirpitz.
