The Nevada class comprised two dreadnought battleshipsÐ Ð†Ð â€šÐ²Ð‚ÑœNevada and OklahomaÐ Ð†Ð â€šÐ²Ð‚Ñœbuilt for the United States Navy in the 1910s. They were significant developments in battleship design, being the first in the world to adopt "all or nothing" armor, a major step forward in armor protection because it emphasized protection optimized for long-range engagements before the Battle of Jutland demonstrated the need for such a layout. They also introduced three-gun turrets and oil-fired water-tube boilers to the US fleet. The two Nevadas were the progenitors of the standard-type battleship, a group that included the next four classes of broadly similar battleships that were intended to be tactically homogeneous.
