Plenty of convoy battles occurred in the Pacific, but as you wish.
And, honestly, the Soviets did a LOT of convoy guarding. Mostly British supplies coming in form Canada IIRC.
In any case... if you take RN, I'll go with KM.
Do you have any examples of significant convoy battles in the Pacific? I am aware of the significance of the USN's effective submarine operations against Japanese shipping, but not that there were engagements on the scale of what happened in the North Sea/Arctic. And yes, the Soviet navy was involved in convoy protection, but compared with what the USN and RN did, their role is pretty minor (to my knowledge, feel free to cite evidence to the contrary).
