HNLMS Jacob van Heemskerck - Tromps Half-sister adopted by the UK navy

[kriegerfaust]

Originally designated as a flotilla leader and a torpedo cruiser in Decker's Fleet Plan of 1931, she was hastily commissioned on 10 May 1940, when Germany invaded the Netherlands. However, as she was not armed she escaped to the United Kingdom, where she was refitted as an air defence cruiser, since these were the only type of gun available, and there was a growing need for this type of ship to protect the convoys. During the Second World War the crew felt that their ship was blessed and gave her the nickname Oude Jacob (Old Jacob). She received the reputation for proficiency, and not a single convoy ship would be lost when she was on duty.

Nice ship, but (of course) no torpedo tubes, which presents a problem for a Destroyer! She could have some improved pen, like the Japanese 100mm ships, I suppose.

 

She could potentially fit at Tier X in an RN/Associates 4 inch armed DD line (which could include ships from the  like Blyska '41, Athabaskan II, Ould Jacob, etc).

Whats wrong with an upper-middle tier AA cruiser with AA consumables, maybe even a new magic spell? Hasnt enough time passed to sell the solution?
