Would a 13.5-inch super-dreadnought protect a convoy?

How would a 13.5-inch-gun super-dreadnought perform as a Second World War convoy escort?

It would be adequate because it could cause enough damage to deter raiders even without being a modern fast battleship.

A convoy escort did not need to overtake and destroy both German ships. It needed enough gun power and resilience to make an attack too costly for distant raiders. A 13.5-inch-gun super-dreadnought was therefore adequate for the role. Mission success depended on damage risk and denial rather than a symmetrical battleship duel.
