Did the Audacious-class carriers require the largest docks, or could other yards build them?
Short answerThey needed large yards; some cruiser yards might build the hulls, but limited facilities narrowed the practical choices.
NotesThe Audacious class needed large shipyards. Some cruiser yards could theoretically have built the ships, but the facilities available at those yards limited the practical options. A yard's ability to accommodate the hull did not by itself establish that it could carry out the complete construction programme.
