Lexington and Saratoga gave the US Navy enough speed, deck capacity, and freedom to turn carrier theory into a fast task-force concept. Royal Navy fast formations combined carriers with battlecruisers and other fast capital ships. Lacking equivalent battlecruisers, the Americans made the carrier the formation's linchpin and organized escorts around it. Japanese practice at this stage remained more closely tied to a massed whole-fleet concept that later developed into the Kido Butai. The comparison links force structure to doctrine because the ships already available shaped how each navy imagined carrier mobility, raiding, and fleet battle.

US carriers become the center of fast task forces
Lexington and Saratoga lead the US Navy toward carrier-centered fast formations, while British doctrine pairs carriers with battlecruisers and Japan initially favors a massed fleet approach.
