Given the political situation, the RAF naturally dedicated the available resources to the development and production of Hurricanes and Spitfires for the defense of mainland Britain. No money was spent by them on developing Naval aircraft.
Illinois was ordered 9 September 1940 and laid down 15 January 1945. Construction was canceled 11 August 1945 when Illinois was 22% complete. She was sold for scrap in September 1958. Illinois' design called for an all-welded hull, lighter and stronger than the riveted/welded hull of the four completed Iowa-class ships. A proposal to redesign the hull with a Montana-class type torpedo protection system was rejected.
Kentucky was ordered 9 September 1940 and laid down on 6 December 1944. Construction was suspended 17 February 1947 when Kentucky was 72% complete. She was informally launched 20 January 1950 to clear a dry-dock for repairs to Missouri, which had run aground. In 1956, Kentucky?s bow was removed and shipped in one piece across Hampton Roads, where it was grafted on the battleship Wisconsin, which had collided with the destroyer Eaton
