Hello everybody,

 

I have put together history and possible implementation of light cruiser HMS Dido in World of Warships.
Please keep in mind that this is just fan made, not official news of upcoming new ship.
Also I apologize for any grammar mistakes, english is not my native language.


HMS Dido
History
Creation
Even before World War II, Royal Navy was aware of a threat posed by aircraft.
The temporary solution was to rebuild old cruisers to floating air defence platforms.
The other solution to this problem was to design a new light cruisers with appropriate air defence armament.
This program produced 16 Dido-class cruisers.
Dido-class cruisers had maximum speed just over 32 knots and could sail up to 4,880 miles with speed at 16 knots.
She was armed with 5x2 5.25 inch dual purpuse guns, 3 turrets on the bow and 2 turrets on the stern.
These turrets were originally designed for the King George-class battleships.
However, thanks to heavy weight of the turrets, these dual purpuse guns weren't excellent for anti-aircraft fight and they weren't very effective against
ground targets. She also carried 2x3 533mm torpedo tubes.

Last five ships of the Dido-class didn't have 3 turrets on the bow, but only 2 turrets. They had reinforced mast and lower-profile smoke funnels.
HMS Charybdis and Scylla were armed with 4,5 inch dual porpuse guns. They were cheaper and had better anti-aircraft capability.

Ships of the class:
-total number of ship produced: 16
-HMS Dido (1939)
-HMS Euryalus (1939)
-HMS Naiad (1939)
-HMS Phoebe (1939)

-HMS Bonaventure (1939)
-HMS Hermione (1939)
-HMS Charybdis (1940)
-HMS Cleopatra (1940)
-HMS Scylla (1940)
-HMS Argonaut (1941)
-HMS Bellona (1942)
-HMS Black Prince (1942)
-HMS Diadem (1942)
-HMS Royalist (1942)
-HMS Spartan (1942)

 

Carrier
HMS Dido (37) became the lead ship of this new class. Her keel was laid down on October 26th, 1937 by Cammell Laird of Birkenhead.
She was launched on July 18th, 1939 and commissioned on September 30th, 1940.
Dido's first mission, in November 1940, was to escort the aircraft carrier Furious to West Africa.
Dido then spent four months on convoy duty in the Atlantic before running suppliesto Malta where she joined the Eastern Mediterranean Fleet in April 1941.
In May 1941, she was sent to Crete and assisted in evacuation of the British forces.
On 29 May 1941 Dido was badly damaged by bombs whilst taking troops from Crete to Alexandria.
Then Dido was sent to the Brooklyn Navy Yard. There she was refitted and rejoined the Eastern Mediterranean Fleet in December 1941.
The first three months of 1942 were spent on convoy escort duty between Alexandria and Malta. In March that year, Dido took part in a bombardment of Rhodes.
A week later she participated in the Second battle of Sirte.

 

On 18 August 1942 she returned to Massawa for repairs of the bomb-damaged stern.
Dido then spent the rest of the year supporting the British campaign in North Africa before being transferred to the Western Mediterranean Fleet in December 1942.
After that, Dido performed the duty of anti-aircraft guard at Bone and Algiers until March 1943.

In April 1943, Dido returned to Liverpool for a 3-month refit before rejoining the Western Mediterranean squadron.
In May 1943, Dido took part in diversionary bombardments against North Sicily during the landings.
Dido was then used as an anti-aircraft guard for invasion bases at Palermo and Bizerte.


On 12 September 1943, Dido escorted 600 troops to Taranto where the Italian Fleet surrendered. From Taranto, Dido went to Sorrento where she supported troops.
October and November 1943, Dido returned to Alexandria for another refit. On return to service, Dido spent time in Malta and Taranto.
After that, she participated in a diversionary action off Civitavecchia in support of the landing at Anzio.
In August 1944, Dido supported the Allied landings in France and in September 1944 Dido returned to the UK.

In October 1944, Dido escorted a convoy to Russia before supporting carrier strikes off Norway.
In April 1945, Dido escorted Apollo, Orwell, and Obedient to the North Kola Inlet to lay mines.


Dido's last mission in the war was to go to Copenhagen, firing the last naval shot in the war in Europe on the way, for the surrender of the German

Kriegsmarine which was signed aboard Dido. After the signing, Dido escorted the German cruisers Prinz Eugen and Nürnberg to Wilhelmshaven.

In July 1945, Dido took King George VI and Queen Elizabeth to the Isle of Man.
In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II.
She was decommissioned and sold for scrap to Thos W Ward and scrapped at Barrow-in-Furness in 1957.

HMS Charybdis

 

Summary:
Dido is light AA cruiser, similar to Atlanta, at tier VI and she plays very similar to Atlanta.
Dido would have the "catapult launcher" guns with fast reload and weak armor.
However, there are few differences: -Dido has better torpedoes
                                                               -Atlanta has more guns
                                                               -Dido has better concealment

                                                               -Dido is one tier lower
Because it is very similar to Atlanta I made 2 hull options:
                      -Hull A- more guns with slower reload and better range and damage per shot
                                - worse concealment than Hull B
                                - only one consumable (I dont count Damage control party)
                                - slightly worse torpedoes 
                                - slightly better long range and medium range AA defence
                      -Hull B- less guns with lower caliber and damage per shot and slightly worse range
                                - slightly better concealment
                                - one consumable more
                                -better short range AA defence


Reason why I made two hulls for Dido is simples. I didn't want Dido to be Atlanta at tier VI.
Also it is good to have options. Hull A has more damage per minute while Hull B is for more dangerous gameplay.

 

 

I will be glad if you leave your comment below. I hope you enjoyed this article and have a nice day.

I'd suggest taking the name from some other ship of her class. I'm sure you can see why

The author Alistair MacLean for some of his naval career was on HMS Royalist (a Dido class light Cruiser) his experience on the Arctic Convoys led to his first novel HMS Ulysses.

 

The novel focuses on HMS Ulysses a fictional mutinous Dido type light Cruiser leading an arctic convoy; (and as currently available in WOW) features a Type C class light Cruiser;  a Town class lend lease destroyer; Several American built Escort Carriers similar to the Bogue, and at the very end a German Hipper class heavy Cruiser as well as not in WOW an S class destroyer, V&W class destroyers and other smaller RN ships.

 

If you want to get a sense of the true horror of an arctic convoy with the appalling weather and great dangers above and below the waves this is a good place to start.

The D Class cruiser HMS Dragon fired the last naval shots of WW1 when she fired on German seaplanes off the Heligoland Bight on 9th November 1918 and the last shot is credited to Maurice Green a South African.

 

HMS Dido is credited with the last naval shot of WW2 when she fired a single shot at an approaching lone German aircraft on May 8th 1945 (VE day) which then turned away. This was as she was  heading towards Copenhagen to accept a German Naval surrender. The crew of the gun is not known.
