Montana's armour included a 16.1-inch belt, an 18-inch forward bulkhead, a 15.25-inch aft bulkhead, and 22.5-inch turret faces. The heavier forward protection suited a ship expected to approach the enemy before turning to bring all guns to bear. Weight distribution across the broad hull and machinery spaces also influenced the unequal bulkheads. The turret faces answered both long engagement ranges and the expectation of repeated attacks during a Pacific advance. Armour protected the mechanisms and the experienced crew needed for damage control, repair, and continued operation, whose accumulated knowledge could not be replaced quickly.
