"The Dido class was a class of sixteen (including five within the Bellona sub-class) light cruisers built for the British Royal Navy. The design was influenced by the inter-war Arethusa-class light cruisers. The first group of three ships were commissioned in 1940, the second group (six ships) and third group (two ships) were commissioned between 1941–1942. The Bellona subclass ships were commissioned between 1943 and 1944. Most members of the class were given names drawn from classical history and legend. Post war in the expanded 1951 programme of the Korean War Emergency a broad beam Bellona class armed with 4 twin Mk 6 4.5 guns  was considered as a cruiser option along with the 1951 Minotaur class  and the Tiger class completed with two Mk 24 6 inch turrets and 4 twin Mk 6 4.5. From the initial trials of the lead ship of the class, Bonaventure the new light cruisers were considered a significant advance, with the 5.25 turrets, far more modern in design than previous light cruiser turrets, and offering efficient loading up to 90 degrees to give some DP capability. While some damage was experienced initially in extreme North Atlantic conditions, modified handling avoided the problem. The fitting of the three turrets forward in A,B and Q position depended on some use of Aluminium in structure and the non availability of aluminium after Dunkirk was one of the reasons for only 4 turrets being fitted to the later ships.

The Dido class were designed as small trade protection cruisers and for action in the Mediterranean Sea, where they were surprisingly effective in protecting crucial convoys to Malta and managed to see off far larger ships of the Italian Royal Navy. The 5.25-inch (133 mm) gun was primarily a surface weapon, but it was intended to fire the heaviest shell suitable for anti-aircraft defence and accounted for around 23 aircraft and saw off far more. Four original Dido-class ships were lost during the war: HMS Bonaventure, HMS Charybdis, HMS Hermione, and HMS Naiad. The original ship of the class, HMS Dido, was mothballed in 1947 and decommissioned ten years later. HMS Euryalus was the last remaining in-service ship of the original class, being decommissioned in 1954 and scrapped in 1959.

The Bellona class (as well as four rebuilt Dido ships) were mainly intended as picket ships for amphibious warfare operations, in support of aircraft carriers of the Royal Navy and United States Navy in the Pacific. HMS Spartan was the only ship of the sub-class to be sunk, struck by a German Fritz X while supporting the Anzio landings. Post war modernisation proposals were limited by the tight war emergency design which offered inadequate space and weight for the fire control and magazines for four or five 3-inch twin 70 turrets combined with the fact the heavy to handle 5.25-inch shells fitted when the cruisers were built had a large burst shock which made them a more effective high level AA weapon than post war RN 4.5-inch guns. HMS Royalist was somewhat different from the rest of the class, as it was modified to be a command ship of aircraft carrier and cruiser groups intended for action against German battlecruisers. It was later ordered to be rebuilt, by Winston Churchill, for potential action alongside HMS Vanguard against the post-war Soviet Sverdlov-class cruisers and Stalingrad-class battlecruisers. In 1956, Royalist was loaned to the Royal New Zealand Navy (RNZN), with whom it served until 1966. Despite being part of the RNZN, Royal Navy officers made up the majority of the senior command. During the Indonesia–Malaysia confrontation, it was regarded not only as the last Dido-class ship but also the last cruiser of the Royal Navy. The ship was decommissioned in 1967.

The class were intended to be armed with ten 5.25-inch (133 mm) guns in five twin turrets, which were of the same circular design as the secondary armament in the King George V-class battleships. A shortage of the guns, due to difficulties in manufacturing them, led to the first group being armed with only eight 5.25-inch guns in four twin turrets. The fifth twin turret was added later to Dido only. The first group was also armed with a 4-inch (102 mm) gun for firing star shell and two quadruple QF 2-pounder (40 mm) "pom-poms".

The second group had the five twin 5.25-inch guns but did not have the 4 in (102 mm) gun. The third group's armament was changed due to the shortage of 5.25 in guns, being armed with eight 4.5-inch (113 mm) guns in four twin turrets instead. The 4.5-inch gun was better suited to the primary anti-aircraft role of the Dido class. The forward A & B 4.5 turrets were mounted on the top of conjoint deckhouses, extending the superstructure to allow the 2 cruisers to play a flagship role with more accommodation and radar rooms. The high mounting of the 4.5 turrets forshadows the high freeboard and superstructure of the twin 4.5 A & B mounting on the County GMDs, 20 years later. The high rate of fire of the 4.5 turrets and the unique arrangement for a British cruiser of the shell and charge being loaded in a combined case,and simpler DP twin DCT, Red DCT for A 7 B and Blue for X & Y m meant in many senses the Scylla and Charbydis were the only Dido class that were, true AA cruisers The 4.0-inch (102 mm) gun was also fitted and the 2-pounder armament was increased from eight to ten.

The Bellona subclass differed in appearance somewhat from their predecessors. They had eight 5.25-inch (133 mm) RP10MkII guns in four twin turrets and had greatly improved anti-aircraft armament, with twelve 2-pounder guns and twelve Oerlikon 20 mm cannons. The bridge of the Bellona class was lowered by one deck compared to the previous three groups, which allowed full radar control to be fitted to the 5.25-inch (133 mm) turrets and 2-pounder guns, due to the decreased topweight. These ships used the HACS high angle fire control system. The two funnels were more upright than the raked ones of the original Dido class.

In World War II, the Dido class saw much action, including the Battle of Cape Matapan, the Second Battle of Sirte, Operation Torch, Operation Overlord and the Battle of Okinawa, as well as many other duties in the Mediterranean and Pacific. The class lost five ships during the war (Bonaventure, Charybdis, Hermione, Naiad, and Spartan); in addition Scylla was badly damaged by a naval mine and declared a constructive total loss. The post-war survivors continued in service; all were decommissioned by the 1960s. Bellona, Black Prince and Royalist were lent to the Royal New Zealand Navy post-World War II. In 1956, Diadem was sold to Pakistan and renamed Babur.

The Dido's

Bonaventure completed with only four twin 5.25 in turrets because of shortages and received a 4-inch starshell gun in "X" position. She had received a radar set before October 1940 but was otherwise unaltered.

Naiad completed with five turrets. She received five single 20 mm in September 1941 and had radar Type 279 by this time.

Phoebe completed with four turrets and was fitted with a 4-inch gun in "Q" position forward of the bridge. The latter was landed during her refit between November 1941 and April 1942 at New York City, along with the .5-inch machine guns and Type 279 radar, while a quadruple 2 pdr supplanted the 4-inch gun and eleven single 20 mm guns were fitted. Radars were now Type 281, 284 and 285. The "A" turret was temporarily removed at the end of 1942 after torpedo damage. During repairs in the first six months of 1943, all three quadruple 2 pdr mounts were landed, as were seven single 20 mm, to be replaced by three quadruple 40 mm Bofors guns and six twin 20 mm. Radar Type 272 was also fitted. A turret was replaced in July 1943. Her light anti-aircraft weaponry in April 1944 was twelve 40 mm (3 × 4) and sixteen 20 mm (6 × 2, 4 × l).

Dido had four turrets and a 4-inch gun similar to Phoebe. The 4 in and the machine guns were removed in the latter half of 1941 at Brooklyn Navy Yard, when Q 5.25 in turret was shipped and five single 20 mm were fitted. In the early summer of 1943 three single 20 mm were exchanged for four twin 20 mm and the radar outfit was altered by the addition of Types 272, 282, 284 and 285. April 1944 lists show only eight 20 mm.

Euryalus completed with her designed armament. In September 1941 the .5 in MGs were landed and five single 20 mm fitted. Two more were added by September 1942. By mid-1943 two single 20mm had been removed and four twin 20 mm shipped. The type 279 radar was replaced by types 272, 281, 282 and 285. In a long refit from October 1943 to July 1944, Q turret was replaced by a quadruple 2 pdr and two twin 20 mm were fitted. Radar 271 and 272 were removed and types 279b, 277 and 293 fitted.

Hermione was also completed as a five-turret ship. She had the .5 in MGs removed in October/November 1941 and received five single 20 mm.

Sirius was completed with five turrets and five 20 mm. She had received two more 20 mm by mid-1943. One of these was landed at Massawa at the end of 1943 and two 40 mm Bofors Mk III were fitted. She is listed as having only seven 20 mm as light AA in April 1944. By April 1945 she had two Mk III 40 mm fitted and had landed two single 20 mm.

Cleopatra was completed with two 2-pounders in 1942 in lieu of the .5 in MGs but these were removed in the middle of the year and replaced by five 20 mm. A sixth 20 mm was added in mid-1943. During repairs between November 1943 and November 1944, Q turret was removed, as were two quadruple 2 pdr and five 20 mm. Three quadruple 40 mm Bofors and six twin 20 mm were fitted and the singles numbered four. In 1951 the US sourced quad bofors and Oerilikon's were replaced by 3 twin MK 5 Bofors and 8 single Mk 7.

Argonaut was completed with four single 20 mm in lieu of the .5 in MGs. She had Q turret removed during repairs in 1943/44, and lost the four single 20 mm. She received a quadruple 2 pdr in lieu of the 5.25 in, and had five twin 20 mm fitted. By April 1944 her light AA comprised three quadruple 2 pdr, six twin power-operated 20 mm and five single. By the end of the war with Japan she had received five 40 mm Bofors and three single 40 mm Bofors Mk III.

Scylla was completed with four twin 4.5 in Mk III in UD MK III mountings because of a shortage of 5.25 in mountings. The forward superstructure was considerably modified to accommodate these and also to increase crew spaces. Her light AA on completion was eight single 20 mm. Six twin power-operated 20 mm were added at the end of 1943.

Charybdis was also completed with four twin 4.5 inch, and had in addition a single 4 in Mk V forward of X mounting. Her light AA at completion was four single 20 mm and two single 2 pdr. The 4 inch starshell gun and two single 2 pdr were removed and replaced by two twin and two single 20 mm, probably in 1943.

Bellonas
Spartan received no alterations as far as is known.

Royalist was converted to an escort carrier squadron flagship immediately on completion, when an extra two twin 20 mm were fitted as well as four single 20 mm. She was the only ship to receive an extensive postwar modernisation ordered for the RN but was later sold to New Zealand. Plans were drawn up to fully modernise the four improved Didos with either four twin 3 inch L70 guns or Mk 6 4.5 inch guns. However, that would have required building new broad beamed Didos (as was seriously considered in 1950-54). This was because the magazines of the Royalist type could hold only enough 3 inch ammunition for 3 minutes and 20 seconds of continuous firing. The refit of Royalist was shortened and that of Diadem abandoned because new steam turbines were regarded as both necessary and unaffordable. Royalist′s reconstruction, like that of Newfoundland, incorporated much of the RN's late 1940s and early 1950s view of a desirable cruiser. Royalist′s 5.25 inch armament was given some of the improvements of the final 5.25 inch mounts built for Vanguard, but not the extra space or power ramming. Also added was a secondary armament of 3 STAAG auto twin 40mm, new 293, 960M radar and Type 275(2 sets) DP fire control for the 5.25 guns, and a lattice mast. (Royalist was loaned to the RNZN in 1956, in exchange for Bellona).

Bellona had four single 20 mm added by April 1944, and received an extra eight single 20 mm by April 1945. (She was loaned to the RNZN after the war and operational 1946-52, the twin Oerlikons had been replaced by 6 single MK3P 40mm in the RNZN unique kiwi electric powered mount, but Bellona was never actually fitted with 6 standard tacymetric directors, requested by the RNZN for controlling the Bofors. The RNZN mothballed the quad pom pom mounts for manning reasons, but maintained the single oerlikons on HMNZS Bellona.).

Black Prince and Diadem also received eight single 20 mm, and had a further two twin 20 mm by early 1945. (Black Prince was loaned to the RNZN after the war and was operational briefly in 1947 before part of her crew mutinied and were discharged, and after a 1952 refit with 8 single Mk3P 40mm which were electric powered, like the RN Mk 9 and 6 single Oerlikon and operated till 1955, which included a visit to the 1953 Fleet Review at Spithead. Diadem was sold to Pakistan in 1956, after a modest refit with 293 and 281 radar and standardised 40mm twin and single light AA guns. Her 5.25" guns were fired in Pakistan's brief war with India in 1961. Diadem became a cadet training ship in 1962 and was renamed Babur)."

They were basically RN versions of the USN Atlanta, and in-game could possibly work the same; instead of radar getting a British heal?

I honestly don't know for this one, tell me what you think they could do for this series of ships.

Eh, even so Snarg, I'd be up for a British mini-Atlanta, or a "Mini-taur" if you will (I'll be here all week, folks!). Looks like she'd make a good trainer now that Belfast is a verboten boat. I'll take eight!

So another British machine gun boat? Pass.

Also, I know there's an extra D in the word, but I my mind always sees it as the Dio-class.

I've advocated for a Dido-class in this game since the RN light cruisers were first announced, and probably even before then. They fit right in as a Tier VI premium, with characteristics similar to the Atlanta (i.e., infinite charges of DFAA) and instead of radar, give her a creeping smokescreen like Perth and Haida as well as possible hydroacoustic search.

She'd be a bit squishier than an Atlanta, but would be able to perform well as a scout cruiser and cap support ship with a rapid-fire main battery.

I think that we'll see the Dido at some point at an RN premium CL.  Like the OP said, it sounds a lot like an RN Atlanta.  Give it the normal RN CL consumable package and she could be good to go.  About the only question might be AP only (like tech tree RN CLs) or AP and HE.

Either you or your source stole the content from Wikipedia...no source acknowledgement? That bothers me. I don't a #2 about your desire for the ship...let it come....but your ripping other peoples research for your own pisses me off.

Well, given that the first Dido's were designed, launched and commissioned before the Atlanta I'd argue that the Atlanta was the USN version of a Dido rather than vice versa ;)

 

I'd like to see them, but I don't hold out much hope of it happening any time soon. The last (and only) RN premium cruiser was released in 2016, and WG plainly give zero stuffs about that particular nation/type.

A basic Dido is effectively a T5, with some gimmicks T6.

To be fair, although it can't train captains because Commonwealth, Perth is also basically a premium RN cruiser. 

I think we'll get at least a couple of the more famous RN heavy cruisers as premiums sooner or later. Exeter would make a great t6 premium and they could sell it with Graf Spee as a combo deal. Norfolk, Suffolk, or Berwick would be notable enough to represent the County-class as a t7 premium.

Hey, at least you removed the footnote numbers from the wikipedia page, thats something :Smile_teethhappy:

As for tier, I think she would he comfortable at tier VI with a few tweaks. I would definitely buy her as a discount Atlanta, she wouldn't be too shabby for OPs either.

Well Perth (if you count her) was released within about a month of Belfast, also in October/November 2016 or coming on for 2 years ago - there hasn't been one announced so the very next one we might see would possibly be in 3 months or so - after Alaska, Stalingrad, Le Terrible, Prinz Eitel, Jean Bart.

Not much coming, later rather than sooner.

Don't forget HMS Aurora (Huang He)

But, yes, with HMS Belfast removed from the premium shop there is a gaping hole in the RN lineup. Which isn't unusual given the insecurity usually shown towards those lines...

While not looking like a strong British cruiser captain trainer like the belfast ever was, it's training program is more akin to that of would be captains for the upcoming British DD line.

I wouldn't be too hopeful. WG has shown often enough that they don't give much of a crap about British ships, and have no clue how to handle them, other than throwing darts at their gimmicks board.

The biggest issue with the Dido's is that their main guns are slow firing and don't have great AAA, they're the same guns you'll find as secondaries on KGV. That would make these ships struggle above T5 IMO.
