I modified my Siamese Large Destroyer design to be laid down at 1942 and carry the weapons of your choice, with some of them somewhat modified. For example, your torpedoes are way too short. Usually I give the length as diameter x 15.
She's built for speed @ 37 knots. Reasonable range is maintained at 8500 nm @ 15 knots.
