If Britain never paused carrier construction

How many British carriers might be ready by November 1941 if carrier construction were not paused in 1939?

The estimate is six by or near November 1941: the four Illustrious-class ships, Unicorn, and Implacable, with Indefatigable following.

Without the 1939 construction pause, launch and completion dates are estimated to move forward by roughly six months, sometimes more. The four Illustrious-class carriers could all be in service during 1940. Unicorn and Implacable might bring the total to six commissioned or nearly ready by November 1941, with Indefatigable following soon afterward. Earlier completion would also mean accepting earlier designs, before some later radars, antiaircraft weapons, and changes for American aircraft became available. Audacious-class and light-fleet carriers were historically laid down later and are treated more cautiously: removing the pause does not establish exactly when those programs would begin. These are conditional estimates based on uninterrupted yard work, not guaranteed commissioning dates.
