Warship Wednesday March 18, 2015 Her Majesty’s Final Cruiser

Here at LSOZI, we will take off every Wednesday to look at the old steam/diesel navies of the 1859-1946 time period and profile a different ship each week. These ships have a life, a tale all of their own, which sometimes takes them to the strangest places. – Christopher Eger

Warship Wednesday, March 18, 2015, Her Majesty’s Final Cruiser

Blake8

Here we see the Minotaur-class cruiser, Her Majesty’s Ship Blake, pennant C99, of the Royal Navy as she appeared after her refit to accommodate both a fleet flag suite and a quartet of helicopters.

When the Royal Navy entered World War II, they did so with several modern light cruisers to include 10 11,000-ton Town-class and had another 11 improved Crown Colony-class vessels on the builder’s ways.

However, within the first couple years of the war, the fleet lost a number of these ships to include HMS Fiji and HMS Gloucester (both sunk in an air attack at Crete, 22 May 1941) HMS Trinidad (scuttled following air attack off North Cape, 15 May 1942), HMS Southampton (scuttled following air attack off Malta, 11 January 1941), HMS Manchester (scuttled following torpedo attack off Cap Bon, 13 August 1942) and HMS Edinburgh (scuttled following torpedo attack, 2 May 1942).

With the RN down a quarter of their new cruisers and a long war expected, the call went out in another nine emergency ships to be funded as part of the Additional Naval Programme also known as the “something keeps happening to all of our bloody cruisers” program.

These new ships would be the Minotaur-class light cruiser.

Fundamentally an improvement of the Crown Colony-class design that was already being built, these 11,130-ton ships could make 31.5-knots which didn’t make them the fastest cruisers in the world, but the fact that they could steam at an economical 16-knots (the going rate for convoys) for 8,000 nautical miles on a single fill-up made it clear they were intended for distant travels.

Armed with 9 6″/50 (15.2 cm) BL Mark XXIII guns in 3 triple turrets, they had the same big tubes as the rest of the Commonwealth light cruiser fleet. These guns could fire a 112-pound shell to a maximum of 25,480 yards and the Minotaur-class was set up to carry as many as 1800 shells in their magazines at a rate of 6 rounds per minute per tube.

The thing is, by 1943, the Royal Navy was concentrating more on destroyers, and small escorts, which meant the new Minotaur‘s were put on the back burner.

Only one, HMS Swiftsure was completed during the war and even this ship just became operational in late 1944 (rushed to the Pacific she was the flagship of the British Pacific Cruiser Squadron, and was selected by Admiral Cecil Harcourt to hoist his flag for the Japanese surrender.) Class leader Minotaur was transferred before she was complete to Canada who commissioned her as HMCS Ontario almost a month after Hitler ate a bullet (or went to Argentina whichever you believe). A third ship, HMS Superb, was commissioned after the war.

That left six incomplete hulls at the end of WWII, lingering.

Three of these, Mars, Hawke, and Bellerophon were canceled, their steel broken back up and recycled.

Three floating hulls that had made it far enough to be launched, Tiger, Lion, and Blake, were left hanging out while the Admiralty decided what to do with them.

This brings us to the hero of our story.

Laid down 17 August 1942 at the Fairfield Shipbuilding and Engineering Co Ltd, Govan, Glasgow, Scotland, Blake was launched 20 December 1945– some three months after the end of World War II, and work was suspended. Named after Admiral Robert Blake (1598-1657), considered the founder of what became the modern Royal Navy, of whom even Nelson wrote, “I do not reckon myself equal to Blake” she was the fifth (and last as of 2015) RN warship to bear his name.

Finally, after nine years of languishing, it was decided to complete the three floating but yet unfinished Minotaurs, Blake included, to a modified design due in large part to the perceived threat of the new Soviet Sverdlov-class cruisers.

This modification amounted to scrapping the entire armament scheme to include 6 and 5-inch guns, AAA pieces, and surface torpedo tubes, in exchange for a trio of twin 3″ guns QF Mark N1 DP guns and a pair of twin 6″/50 (15.2 cm) QF Mark N5 mounts.

The latter, only mounted in these three post-WWII British light cruisers, were the first to use complete cartridges rather than bagged powder under a shell. As noted by Navweaps, “Controlled by the Gun Direction System (GDS1) using the Type 992 radar. This system enabled the ships to engage multiple targets within a few seconds of each other and was technically very advanced for its time.”

Out of the six turrets used afloat, three used RP15 hydraulic control, and three used RP53 electric control. It is believed that HMS Tiger had all hydraulic control; HMS Blake had all-electric control while HMS Lion had one of each. They could fire a 133-pound shell 20 rounds per minute per tube to about 25,000 yards.

As such, the four tubes on Blake and her two full sisters could dish out 80 shells in a frantic minute while their original 9-gun Minotaur half-sisters could only fire 54.

Science!

With the three “new” cruisers entering the fleet, the RN took their half-sister baggers Swiftsure and Superb out of service and both were scrap by 1962. The Canadians followed suit with Ontario/Minotaur.

Finally commissioned 18 March 1961, HMS Blake took to the sea.

After just two years she was withdrawn and converted once more in 1965 to become one of the first modern helicopter cruisers.

While she retained her forward mounts, those aft were replaced by a hangar enormous enough to fit a quartet of Wessex (later Sea King) helicopters inside. Additionally, she was given room, space, and commo equipment to serve as a fleet flagship.

Further, she was given realistic anti-air protection in the form of a pair of quad GWS.21 Sea Cat missile launchers. Short-legged surface-to-air missiles with a range of about 5km, Sea Cat was effective enough to earn at least one confirmed kill in the Falklands.

Rejoining the active list in 1969, she was perhaps one of the only cruisers to have a Harrier jump jet land upon her.

On the 52nd anniversary of Sqn Cdr E.H. Dunning’s first landing on board the cruiser, HMS Furious in 1917, 2 August 1969, Hawker Siddeley Aviation chief test pilot Hugh Merewether landed an experimental early Harrier onboard the cruiser HMS Blake.

Her sister Tiger was similarly converted while the Lion was cannibalized for future spare parts.

Then there were two…

Blake endured through the 70s as something of a love boat design: big and expensive to operate and only trotted out for special occasions.

She had happy if mechanically troublesome cruises in the Med, Indian, and Pacific before a 1980 refit saw her placed in mothballs, the Invincible-class “harrier cruisers” built to replace Tiger and Blake.

When the Argentinians moved into the Falklands/Malvinas in 1982, both Blake and Tiger were pulled out of storage and readied for use in the South Atlantic. As the Royal Marines and Paras only brought 105mm light guns with them, it was thought that the rapid-fire 152mm models of Tiger and Blake may help in naval gunfire support while the extensive helicopter facilities allowed them to be lily pads for thirsty harriers and choppers.

However, the war soon proved faster than the old cruiser’s reactivation and, following the conflict, both Blake and Tiger were sold for scrap.

In all Blake spent just 15 years of her 40-year life in active fleet service and, though technically part of the RN during WWII, Korea, and the Falklands, never fired a shot in anger.

Blake was the last cruiser in the Royal Navy and, when she ran her battery before entering refit in 1979, fired the last “big gun” salvo in Britannia’s history.

The bell of the last HMS Blake, scrapped in 1982, is on display in Saint Mary’s Church, Bridgewater while numerous statutes and plaques exist for her namesake.

HMS Belfast, a Crown Colony-class cruiser preserved as a museum ship in London, is the closest living survivor to the “Shakey Blakey.”
