Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ...since the I3-inch gun mounting actually occupies a space of that width; and. since the turret and barbette together are about 20 feet high, this would add about 160 square feet to the target area, while the target area of the 8-inch superposed turret is only about 118 square feet. Moreover, the use of a third 13-inch gun would add at least one-third to the weight of an ordinary turret installation for two 13-inch guns, and this must be a much greater increase of weight than the saving of weight which would result from removing the two 8-inch guns. The port plate, moreover, which must be relied upon to stand the brunt of attack, would have to be made in two pieces in the case of a three-gun turret, and would be correspondingly weakened, since the dimensions of the present port plate for a two-gun turret cannot be much exceeded in manufacture. Actually I believe that a considerably greater increase of diameter than 8 feet would be necessary to allow the use of a third I3-inch gun, especially as guns with 2800 f. s. muzzle velocity are called for. This would require a much larger chamber than that of our present I3-inch gun. and a correspondingly greater diameter of breech. Again, with two guns in a turret the breech mechanisms are made one left and the other right handed, but with a third gun in the middle space would have to be allowed for opening the breech to one side or the other, unless some new system of breech closure be used. On the whole, I believe that, if the details of a triple gun turret were worked out, it would prove to have so many disadvantages as to far outweigh its advantages, even supposing that they exist to the full extent claimed. Another feature of the proposed battery arrangement is the large are over which the...show more
