Doug, I am fairly sure that the above warship is not the Troubridge. I do believe that she is HMS Kelly, the first command of Lord Louis Mountbatten. Pictured here making smoke at high speed.... though I may be wrong
Its not the Kelly, on two criteria, Kelly's main armament were 3 x twin turrets (6x4.7", the above picture features single guns in a different turret arrangement, probably 4.7" calibre though, and David was right she was sunk off Crete 23/05/1941.
On revisiting this I think that she is probably either a "T", a "U" or a "V" Class vessel. there were over a dozen relatively similar classes spanning WW2. Some had twin turrets others single 4.7" or even 4.5" guns. Basic profiles were very similar, but there were various individual fits and mods!!....so thats the best I can do currently. If anyone else has more info or would like to comment further then would love to hear it. Cheers...
David, are you sure the pic was taken in 1964? The ship is certainly an RN design destroyer. She is before the Battle Class. The problem is that the only earlier destroyers left in the RN in 1964 were the eight Ca Class. All eight had completed a major modernisation programme by 1961. The modernisation involved a different fire director from the one in the pic, the removal of the X Turret and the after torpedo tubes and the substitution of a long deckhouse for two Squid ASW mortars plus a twin Bofors AA gun.
Another problem is that the main guns do not look like those fitted in the Ca Class, which had a larger shield. All of the other RN WW II destroyers were converted into emergency programme frigates, which seriously altered their appearance.
As you say David, the absence of a hull number is very odd.
A fair number of ex RN destroyers were transerred to other navies at the end of WW II, but it looks like a White Ensign on the stern of the ship in the pic. Even these transferred ships had largely gone by 1964. You may like to consider the following possibilities: -
Norway - Four Bergen Class - Ex Cr Class.
Pakistan - Two ex Cr, plus two ex Ch Class.
South Africa - Two ex W Class
Turkey - One ex O Class
Egypt - Two ex Z Class
Israel - Two ex Z Class
I have to agree with Doug that this is a T, U or V class destroyer. All the earlier classes were gone by 1964 but a few of the former were still about. C class had a different type of director so they're ruled out. The lack of pennant numbers would denote that fact she was designated a leader. Unfortunately, none of my references point to an identity. I'll keep looking.
