The Royal Navy also cancelled eight new capital ships, four G 3 class battlecruisers and four N 3 type battleships, but none of these ships were under construction at the time, and financial limits suggest that they would probably never have been built. Die Einführung von in der Nähe verschmolzenen Flugabwehrgeschossen im Jahr 1943 machte die 5 in / 38 in dieser Eigenschaft noch leistungsfähiger. August 1941) und Colorado (26. El Colorado acorazados -class eran un grupo de cuatro barcos de guerra construidos por la Armada de los Estados Unidos después de la Primera Guerra Mundial.Sin embargo, sólo tres de las naves se completaron: Colorado, Maryland, y Virginia Occidental.El cuarto, de Washington, era más del 75% completado cuando se cancelará en los términos del Tratado Naval de Washington en 1922. El Mark 12 disparó un proyectil de 55,18 libras (25,03 kg) a un alcance máximo de 17.392 yardas (15.903 m) y una elevación máxima de 37.200 pies (11.300 m) a una altura de 45 grados. En 1941, la junta solicitó una batería secundaria definitiva de dieciséis 5 pulgadas / 38 en montajes dobles, dieciséis Bofors de 40 mm en montajes cuádruples y ocho Oerlikon simples de 20 mm , aunque no estaban seguros de que los barcos pudieran soportar el peso adicional y tomaría una gran cantidad de tiempo en dique seco para que se lleven a cabo estas modificaciones. [39], In July 1944 she emerged from her repairs and overhaul, and set out to rejoin the Pacific Fleet for combat operations. En 1942, el sistema de defensa aérea de estos barcos se reformó por completo. A pesar de un incidente de puesta a tierra al principio de su carrera, Virginia Occidental recibió grandes elogios por la artillería y la protección de armaduras, y participó en ejercicios para probar las defensas de las islas hawaianas en la década de 1930. The U.S. Navy had done this by a process almost akin to the assembly line, sticking to one basic design per class with a maximum amount of standardization and rationalization. Also, the design called for the use of external, rather than internal, belt armor so that a "break in the continuity of the side structure" would not exist, which would minimum drag in the water and any corresponding waste of power.

In order to commence construction of the ships as soon as possible, bids sent out to shipbuilding corporations noted that if they were selected to build the ships, an alteration to the design of the ships three months after their keels were laid must be allowed. Nur der Rumpf, die Maschinenanlage und die Türme der Hauptartillerie blieben erhalten. Der Wechsel zu größeren Kanonen wurde von den japanischen Schlachtschiffen der Nagato- Klasse veranlasst , auf denen auch acht 16-Zoll-Kanonen montiert waren. Auch von der Colorado-Klasse durften nur noch drei Schiffe gebaut werden, die Washington wurde daher nicht vollendet, obwohl sie bereits zu 75,9 % fertiggestellt worden war. The Mark 12 fired a 55.18-pound (25.03 kg) shell to a maximum range of 17,392 yards (15,903 m) and a maximum elevation of 37,200 feet (11,300 m) at an elevation of 45 degrees. All three ships served as artillery support ships during amphibious operations. After a few repairs at the island of Ulithi, she joined Task Force 54 (TF 54), the pre-invasion shelling group for the invasion of Okinawa, at Kerama Retto. They were the first class of American dreadnoughts to be planned without hull mounted secondary armament, and were thus built from the start with deck mounted secondary guns (the previous two classes had been planned with hull guns but completed without them).
