From what I can see you have twin 3" and twin 40mm forward and twin 40mm aft, but I can only see 2 directors to control all 3. Should there be another director forward? In armament list is only 1 x 40mm - should forward mount be gone.

Good take on an UK armed Charles F Adams.

I like it, a nice take on a British armed Sherman and its well done.
I'm not sure you need an MRS-3 for every mount if you don't intend engaging targets with all mounts simultaneously and on a destroyer some sacrifice is needed to save weight and space.

Great drawings, as always, though the Sea Slug looks huge on Alaungpaya. :)
