Indianapolis B is best played as an American cruiser that creates crossfires, supports the flank, and trades only when the angle is favorable. Balance note: Official updates changed Indianapolis B directly: May 2021: Main battery accuracy improved by about 3%; Maximum damage of the HE shells increased 2,800→3,000; Maximum damage of the AP shells increased 4,600→4,800; Main battery turret traverse speed increased 6°/s→7°/s. Play her as an American heavy cruiser that punishes broadsides while supporting objectives.
Use islands and mid-range angles to bring improved guns onto destroyers and cruisers without exposing broadside.
Do not open-water tank battleships or waste radar/support windows.
Build for accuracy, AP performance, reload, radar/utility, concealment, and survivability.
Use these as direction, not a fixed build sheet: tune the final commander, inspirations, and skills around your roster, matchmaking, and comfort.
