Supporting 4 tubes

—DANFS: "4 21” tt" —Friedman, U.S. Battleships:

—p. 95: "The standard battery for U.S battleships was revised to four underwater tubes. That applies only to the New York and Nevada classes; it had to be abandoned in the Pennsylvania class."

—Chapter 5, p. 107: "On 30 March 1911, the General Board selected a ten-gun, 20.5-knot design (E in Table 7-1)." (The table number here is clearly a typo, as the information is actually laid out on the previous page spread in Table 5-2; Table 7-1 is two chapters and about 5 battleship classes later.) From Table 5-2, p. 104: "Schemes C through H had twenty-one 5-inch guns and four 21-inch torpedo tubes."

—p. 145: "From the New York class on, a two-torpedo broadside was specified, first in the form of a twin tube in one room, and then, from the Nevada class onwards, two torpedo rooms, forward and aft of the main belt."

—Friedman and Jurens, Naval Firepower: p. 292: "The U.S. Navy, however, doubled the number of underwater tubes in the New York and Nevada to four."
