Yeah. The IJN would still be destroyed without ever getting close to the modern ship to counterattack.
It’d be a slaughter.
The greatest menace might be US Navy officers and crew who these days know all about diversity and gender theory and their command structure but are deficient in basic seamanship. My father, a Kings Point grad, was in the Merchant Marine and the US Navy. Even in the 1950s, he noted the poor training and unsuitability for sea duty of many Navy ship officers. The tendency of the Navy was to protect the careers of weak officers, while the Merchant Marine and private ship owners ruthlessly weeded them out.
