Maybe an
O&P-class with a main gun armament of four 45-calibre
4.7-inch Mark IX guns in
single mounts?
As she has a
tripod mast and not a pylon mast, she could be
HMS Oribi (
https://en.wikipedia.org/wiki/HMS_Oribi_(G66)) or
HMS Onslaught (
https://en.wikipedia.org/wiki/HMS_Onslaught_(G04))... But Oribi has a kind of "tower" in place of the searchlight (in the middle of the ship) and no aft mast, so this is probably HMS Onslaught.
