HMS Phoebe has the wrong armament - principally the main battery is 8 x 5.25 inch vice 10 x 5.25 inch -
and I just figured out her history - she joined the Eastern Fleet in time for May 1944 operations - sooner than in stock or anything since.
HMS Euralyus arrived far sooner - we must change the class date - and with the wrong AA armament - but is a 10 gun ship like the class is designed to be. She should arrive at Aden about 1 Jan 1944 (she was in Trincomalee on 16 January). She gets fine radar - Early Waring, Short Range Air Search - and surface warning - but had too many quad 2 pounders and the wrong light AAA.
HMS Argunaut arrives in time to be operationg with carriers in Nov 1943 - almost a year sooner - and that forces us once again to puch the class date back. But her main armament is wrong - so we need a new class definition anyway - she looks like HMS Phoebe with 8 big guns - but these are 5.25s vice 4.5s - and like Phoebe the Q turret has a quad 2 pounder in its place. Curiously - in British parlance - Q turret should be amidships and this one should be C turret - but the AA cruisers uniformly call it Q for some peculiar reason.
Black Prince appears too soon - she was in operations when the game has her appear. She entered the Indian Ocean about 7 Nov 1944. Royalist is similar - should be about 1 March 1945.
According to M.J. Whitley:
Your Phoebe timing is correct. She had at the time 3x4 40mm Bofors and 16 20mm (6x2, 4x1).
Euryalus arrived in 16 January 1945, not 1944. She had a refit from October 1943 to July 1944, during which Q turret was replaced by a quad 2pdr. Light AA armament after the refit was: 3x4- 2pdr, six twin 20mm, five single 20mm. Radars: 279b, 277, 293.
Argonaut, again, was sent to the East Indies in November 1944, covering raids against Sumatra in December. The ship was under repair in Philadelphia until November 1943, during which Q turret was exchanged for a quad 2pdr, then took part in D-Day off Gold Beach and Operation Dragoon in the Med. Light AA armament at the time was 3 quad 2pdr, six twin 20mm, five single 20mm.
Your Black Prince and Royalist timings appear correct.
Dido class armament is a mess - several ships entered service with other than the design armament - there were obviously manufacturing problems with the 5.25in turrets. Several ships had only four instead of five turrets - Bonaventure had a 4in gun in X position, Phoebe and Dido had a 4in gun in Q position initially. Scylla and Charybdis, of course, were completed with four twin 4.5 in shielded mounts. Many ships later lost Q turret for additional light AA guns. The standard late-war armament seems to have been 4x2 5.25 in turrets, 3x4 2pdr or 40mm Bofors, 6x2 and 5x1 20mm.
