In the late 1930s, the U.S. was designing large ships with 305 mm main battery guns to counter cruisers. The most armored of the presented variants was the CA2G project, which, according to the report, was armored "worse than any battleship, but better than any cruiser." The ship, named USS Alaska, became part of a high-speed carrier squadron that operated in the Pacific Ocean. Alaska protected aircraft carriers during strikes on Tokyo and covered the landing operations at Iwo Jima and Okinawa. The ship also participated in the raid on Shanghai.
