Did Doug Clarke work on aircraft carriers, and what did he think of the Invincible class?
Short answerYes; he worked on several carrier and aviation ships and thought Invincible should have been substantially larger.
NotesDoug Clarke contributed directly to carrier-related design work across several British aviation ships. His son recalls drawings for Queen Elizabeth's flight deck and hangar arrangements, as well as work associated with Invincible and RFA Argus. He regarded the Invincible class as undersized and would have preferred another five to ten thousand tons. The recollection connects a naval architect's practical design experience to a recurring lesson about the capability sacrificed when carrier displacement is constrained.
