HMS Scorpion (D64): Renamed Three Times Before She Even Launched

Three Names Before a Single Voyage

HMS Scorpion had an unusually indecisive start to her career. She and a sister, ordered together from J. Samuel White at Cowes on 3 February 1942, began life as Centaur and Celt, part of a planned "CE" class. When the Admiralty reworked the order into a new "Intermediate" design instead, the two ships were renamed Tomahawk and Sword to fit the emerging pattern of naming this new class after weapons, and Tomahawk herself was renamed a second time, to Scorpion, in September 1943, a name with its own pedigree stretching back to the scorpio, the Roman torsion bolt-thrower that Vitruvius describes and the legions took on campaign, making it every bit as fitting a weapon-class name as the one it replaced. All this happened before she had even been launched, a small but curious footnote reflecting the naming reshuffles the Admiralty periodically carried out among ships still under construction during the war.

The First British Destroyers Built Not to Be Stopped by One Hit

The word doing the work in all that is "Intermediate", and it hides the most important thing about her. Until the Weapons, British destroyers were built with their boiler rooms next to each other. There was a reason: it let the uptakes come together into a single funnel, which gave a low silhouette and freed up deck space on a small hull. The cost of it was that one torpedo or one bomb amidships could open both boiler rooms at once and leave a fast, expensive, undamaged-looking ship sitting motionless in the water waiting to be finished off, which happened repeatedly and to a great many people.

The Weapons were the first British destroyers built the other way, with the machinery in units: boiler room, engine room, boiler room, engine room, arranged alternately down the hull so that a single hit could take out half the propulsion and leave the other half turning. The Americans had been doing it for years and the Admiralty had watched. It is not a glamorous change and there is nothing to see from the outside except two funnels where there used to be one, and it is the difference between a destroyer that is damaged and a destroyer that is dead.

What Scorpion is really a survivor of, though, is the cancellations. Nineteen Weapon-class destroyers were ordered and four were finished. Three went on 22 November 1944, Grenade, Halberd and Poniard. Eight more went on 15 October 1945, and one of those eight was Sword, the ship ordered on the same day as Scorpion, from the same yard, as the other half of the same pair. Four more went that December. The names read like an inventory of a weapons museum that was never built: Claymore, Dagger, Dirk, Howitzer, Longbow, Musket, Spear, Carronade, Culverin, Cutlass, Rifle. What got through were Broadsword, Crossbow, Battleaxe, and the one nobody could settle on a name for.

The name itself was in use at the time she was given it. The previous HMS Scorpion (G72) was an S-class destroyer commissioned in 1943, and in the December after Tomahawk became Scorpion she was in the North Sea putting torpedoes into the Scharnhorst. So for a while there were two Scorpions on the Navy List, one fighting a battlecruiser in the Arctic and one sitting half-built on a slipway at Cowes with two previous names behind her.

Commissioned Into a Postwar Navy

Scorpion finally commissioned in 1947, joining the 6th Destroyer Flotilla as one of the Weapon-class destroyers, a design that arrived just too late to see the war it had been ordered for but which found plenty of useful Cold War work in the years that followed, including taking part in the Fleet Review celebrating Queen Elizabeth II's coronation in 1953.

Testing the Royal Navy's New Anti-Submarine Weapon

In 1954, Scorpion took on a significant technical role, undergoing trials as the sole Weapon-class destroyer fitted with a Limbo depth charge mortar, an advanced anti-submarine weapon system that would go on to serve across large parts of the Cold War fleet, making Scorpion something of a proving ground for a piece of equipment that shaped Royal Navy anti-submarine tactics for decades afterward.

Limbo is worth explaining, because "advanced anti-submarine weapon system" could mean anything. It was a three-barrelled mortar mounted aft that threw a pattern of three heavy depth charges ahead of the ship, timed and ranged automatically from the sonar, and stabilised so that it stayed aimed while the ship rolled. The point of throwing charges forwards rather than rolling them off the stern is that the ship keeps her sonar contact right up to the moment of firing, instead of losing it under her own hull for the last two hundred yards and then guessing. It became the standard British anti-submarine weapon for a generation, in the Whitbys, the Rothesays, the Leanders, the Tribals and the County-class destroyers, and it was still being fired in the 1980s. HMS Scarborough (F63) carried two of them.

Rebuilt as a Radar Picket

After a Mediterranean deployment in 1955 and 1956, Scorpion began conversion to a radar picket destroyer at Devonport Dockyard in 1957, a substantial rebuild that saw her torpedo tubes removed and an additional mast fitted carrying an AKE-1 antenna, adapting her for the vital early-warning role that radar picket destroyers performed for the fleet.

She recommissioned in 1959 as the last Weapon-class vessel to complete this conversion, closing out the programme for her entire class.

From Front-Line Duty to Explosive Trials

Scorpion served with the 7th Destroyer Squadron until April 1963, when she was placed in reserve, before being employed for underwater explosive trials at Rosyth, a final period of truly useful technical service testing equipment and procedures for the Navy she had served for over a decade and a half. She was sold on 4 June 1971 to the shipbreakers P. and W. MacLellan and arrived at Bo'ness under tow less than two weeks later, on 17 June, to be broken up.

The phrase "underwater explosive trials" deserves a translation as well, because it is not a comfortable job. A ship used for it is moored at a measured distance from a charge on the seabed, the charge is fired, and instruments record what the shock does to her hull, her mountings, her machinery and her fittings. Then it is done again, closer. What the Navy learns is which parts of a warship break when a torpedo or a mine goes off near her without touching her, which is how most ships are actually damaged, and the answers went into the design of everything built afterwards. It is a use for a hull nobody wants any more, and it is genuinely valuable, and it means the last thing done to Scorpion before she was sold was to blow things up next to her on purpose.

A Destroyer That Helped Shape What Came After Her

HMS Scorpion's career, from her confused early naming through to her role trialling the Limbo mortar and pioneering her class's radar picket conversion, reflects a remarkably important if quiet contribution to the technical development of the Cold War Royal Navy, the kind of proving-ground service that rarely makes headlines but shapes the equipment and tactics used by every ship that follows.
