August, 1910 TAE MARINE REVIEW 331 is open to question) it is patent that the Argentine designs--on the whole --are greatly superior to those of the latest vessels building for the United States navy. Why should this be so? The final cost of the two types will evidently be greatly in favor of the Argentine and American Battleship Designs (From The Navy.) oe . . is given a comparison of the principal characteristics of the latest Argentine battleship with those of the Arkansas class of United States battleships. It is noted particularly that while the displacement of these Argentine battleships is greater than the Amer- mith 23 th over 4. ft. more length and ican something greater beam, the mean draught of the Argentine vessels is 1 ft. less than than that of the Careful invited to the difference of 2 knots in speed and to the fact that the Argen- tine designs call for a bunker capacity of 4,000 tons, as against 2,000 tons for the American, with a similar disparity in oil fuel stowage, namely, 660 tons as compared with 400; in other words, the Argentine ships carry 60 per cent more coal and 65 per cent more oil fuel than the American. Just what, if anything, is sacrificed in the Argentine designs to get 39,500 horsepower as against the American 28,000 does not appear. It is certain that the secondary battery of the Ar- gentine vessels outclasses that of the American. attention is American, while their main batteries © In fuel and ammuni- | identical. tion endurance, the Argentine ships undoubtedly show a permissible max- imum under the limiting conditions; and, even if it' be assumed that the protection of the American vessels is On a par with the Argentine (which are COMPARISON OF ARGENTINE AND AMERICAN BATTLESHIP DESIGNS.
