Would Project Habakkuk have needed a governor-like commander?
Short answerIt would more likely have been led by a commodore or rear admiral with captains responsible for large sections, backed by strong communications and a major Royal Marines presence.
NotesHabakkuk's scale would probably require senior officers to command major sections, with department heads potentially holding captain's rank. A substantial Royal Marines contingent and dense internal communications would support local decisions within an overall command framework. Local authority would be necessary because the proposed structure was too large for every decision to pass through one bridge team. The project would function as a floating base whose organization exceeded normal carrier practice.
