How much displacement would a 90-foot extension add to an Invincible-class carrier?
Short answerThe estimate is about 3,000 tons, taking the ship to roughly 25,000-26,000 tons, with useful additional space in the centre.
NotesThe estimate is roughly 3,000 tons, taking the carrier to about 25,000 or 26,000 tons. Because the length is inserted through the working center of the ship, the added volume can support more power and facilities rather than merely extending the ends.
