British carrier construction beyond Implacable

British carrier construction would continue beyond Implacable and Indefatigable if Germany, Italy, and Japan kept adding carriers. The projection places the two ships in service by 1942 and expects subsequent orders to refine their design. One proposed lineage connects Implacable's 27,000-ton standard displacement to the design study behind Illustrious and Unicorn, based on their similarities. The scenario assumes Britain can build carriers of that displacement under the Second London Naval Treaty without a cumulative tonnage ceiling. Extra peacetime would therefore allow further orders and revised designs to change the eventual carrier force.
