Case
Destroyer No.370 of the Mahan Class, Case, was laid down at the Boston Navy Yard on 19 September 1934 and completed on 19 March 1937. Her displacement was 1,500 tons, length 341 feet overall and beam nearly 35 feet. She carried four 5-inch guns and several smaller weapons as well as 12 21-inch torpedo tubes. She was a sister ship to Shaw, which blew up in the attack of 7 December. Case was moored off McGrew Point and was leaving the harbor at 1715 hours when she identified what appeared to be a submarine, possibly sunken, and depth-charged it for good measure.
