Breaking Ice, in Baltimore Harbor
(See page 1304, August, 1924, Proceedings)
Lieutenant Commander Frank Luckel, U. S. Navy.—Captain Disniukes’ very interesting and instructive article indicates that a battleship can break up ice “four or five feet thick.” The thickness of ice is very difficult to estimate accurately even from an observation of the broken floes. The writer has had some experience in ice navigation in the Bering Sea and in Vladivostok Harbor and vicinity. I believe that four or five feet of newly formed ice is an excellent record, even for a battleship. An unarmored vessel such as the old U. S. S. Saturn could break through only about one foot of new ice. It was impossible to break through thicker ice, not because of insufficient power, but on account of the strain upon the frames and the danger of the ice cutting through the plating. In northern waters it is not unusual for ice to cut through the plating of a steel vessel. Of course, this would not be possible with the Kentucky on account of the heavy ram and thick armor.
