What a Queen Elizabeth-class CATOBAR conversion would entail

A fixed-wing CATOBAR conversion might require inserting a new hull section for additional machinery and greater hangar space. Electromagnetic catapults would increase the electrical requirement enough to justify at least one additional gas turbine. The modular design may provide a practical cut point where cables and services are easier to separate, though the exact position is uncertain from the available plans and images. Such a major alteration would force the ship through commissioning trials again, and a new carrier might prove quicker or more economical by the time purpose-built sections were fabricated and installed.
