Britain combined Dreadnought, three Invincibles, a Bellerophon order, and a reserve of thirty-nine pre-dreadnoughts, with two more familiar ships still under construction. The United States had two slower South Carolinas, while other navies continued building pre-dreadnoughts whose training and performance they understood. Those older battleships remained useful insurance after dreadnoughts appeared. Naval planners treated the transition as an evaluation process that unfolded at different speeds. Britain's unusually large battle fleet and exposure to maritime trade explain why it could move cautiously on another battleship batch while committing more aggressively to battlecruisers.
