Need help in identifying this battleship--USS Nevada, Pennsylvannia or Arizona?
Welcome to History Beta!
The battleship in question is a Florida-class battleship (look for images of the USS Florida before its 1924 modernization).
The picture clearly shows the 10 × 12 in (305 mm)/45 caliber Mark 5 guns and the 16 × 5 in (127 mm)/51 cal guns.
Required, but never shown
