During the Second World War, battleships ceded their leading role at sea to aircraft carriers, and in the post-war years their combat use became completely problematic. However, the US Navy currently has 4 ships of this class - they were built in the early 40s. Moreover, over the past seven to eight years, the battleships have undergone modernization and their service life has been extended for another 20 years. Iowa-class battleships are considered one of the best heavy artillery ships in the world. They are characterized by strong artillery and powerful armor protection, high speed and reliability, which, apparently, extended their life after the end of the war, when all the leading naval powers were in a hurry to get rid of battleships. Apparently, the Americans did not have a clear idea of the prospects for the combat use of ships of this class. war against North Korea, were periodically withdrawn from the fleet into reserve and, finally, in mid-1958 they decided to convert them into attack missile ships, and a little later modernize them again in order to increase the volume of fuel tanks to 16.5 thousand tons. the intention of the US Navy command to continue to use battleships in crisis regions far from the coast of the country in the future.
