Japan divided its ships among an advanced force under Nobutake Kondo, Nagumo's carrier striking force, and a vanguard. Nagumo had two fleet carriers and a light carrier, while the advanced force also carried aviation strength; an additional carrier had already left for Truk on 22 October. Battleships were distributed between the vanguard and advanced force. The arrangement reflected prewar ambush and night-fighting doctrine, and crews continued to use formations they had practiced even when the war challenged their assumptions. The Americans organized two carrier groups, with South Dakota helping fill a gap in Task Force 16's cruiser screen. An explicitly hypothetical night action favors South Dakota against the four Kongos because of her nine 16-inch guns and fire-control equipment. That comparison concerns a surface battle that never occurred at Santa Cruz, which was fought through aviation.
