How did Invincible's aircraft capacity compare with a transport such as Atlantic Conveyor?
Short answerA transport can be packed for a voyage; Invincible needed maintenance and working space for repeated operations, so its normal group did not fill every possible aircraft space.
NotesAtlantic Conveyor's transport load is compared with the space needed to operate an Invincible-class carrier's air group. Packing aircraft for a voyage does not provide the workshops, spares, and access required for repeated flying and maintenance. The familiar 18-aircraft peacetime group is connected to those support needs and to conserving airframe hours. That assigned group was smaller than the ship's physical capacity. A transport's packed load therefore cannot be treated as a sustainable carrier air group.
