Actually, In the Last Post, It was the USS Northampton

I looked up the cruiser USS Hampton that David Ray Mohlenbrink served on at Pearl Harbor, the Doolittle Raid and was sunk at Iron Bottom Sound and could find any mention of a cruiser by that name.

Most likely, he was serving on the heavy cruiser USS Northampton which was not at Pearl Harbor during the attack but at sea with the USS Enterprise, but entered the harbor soon afterwards. It also was on both the Doolittle Raid and sunk in Dec. 1942. Perhaps the crew of the Northampton just referred to it as the 'Hampton.
