A modern carrier in 1845 is first an engineering revolution

Who would make the most use of HMS Queen Elizabeth's engineering manuals if the carrier appeared at Portsmouth in 1845?

Her engineers and Britain's mining and industrial specialists would use them to accelerate technology, while the ship's immediate combat value would be harder to exploit.

Britain would likely summon mining and industrial engineers to understand and support the carrier's machinery. Her own engineering department would become the essential repository for knowledge that contemporary industry could begin copying. In the short term, observers accustomed to judging warships by large guns might underestimate a ship without a traditional battery. Her greatest effect would come through accelerated British engineering and imperial capacity rather than an immediate battle.
