Richard O’Kane became the highest scoring American submarine ace in World War Two, credited with sinking 31 Japanese ships. (Morton is the third highest scoring ace, credited with sinking 19 Japanese ships). In a brotherhood-of-arms story, O’Kane’s war service and that of Mush Morton are deeply intertwined. O’Kane greatly admired and liked Morton and the feelings were reciprocated. They made a great team and Morton placed the highest confidence in O’Kane by reversing the traditional roles: Morton conned the submarine into firing position and made the complex analysis and calculations required to do so while O’Kane manned the attack periscope and made the decision of when to shoot. Once Morton had the boat in position his calm, “any time, Dick” became one of his trademark expressions.
