Commander Ralph Huntington Lockwood returned from the Pacific reporting to the Submarine Base, New London, where he had brief instruction as a prospective submarine commanding officer and after fitting out Mingo (SS-261) assumed command at its commissioning on 12 Feb. 1943. Under his command, Mingo made war patrols in the Caroline Islands, Ponape, Palau and Marianas areas. He was awarded the Bronze Star Medal with Combat "V" and a gold star in lieu of a second Bronze Star for commanding Mingo during this period.

Mingo 225k By now, the length of the fairwater was reduced and by 1944 this was the basic shape of the fairwater. This view of the Mingo (SS-261),which is painted in overall black, was taken on 2 February 1944 during refit at Mare Island. Tripod legs have replaced the cast bases of the 20mm guns and the 4"/50 cal deck gun has been installed. The paint looks glossy but this is due to the rain.
Forward of the Mingo are two Mk5 type LCT. The inboard vessel is LCT 151. I can't identify the other LCT for sure but it is likely to be LCT 152, since Mare Island launched these vessels in pairs.
