The Swordfish comparison uses an all-up weight of about 3,438 kilograms, below three and a half tons. The F-35B example reaches 27.2 tons at maximum takeoff weight, with an empty weight of 14.7 tons. Its fuel and weapons add substantial demands on the carrier beyond accommodating the aircraft itself. Once aircraft, ordnance, and support requirements are considered together, the rough analogy places a modern escort carrier at around 40,000 tons. This is an illustrative estimate of the changed burden, without a fixed relationship between aircraft weight and carrier displacement.

Why modern aircraft change escort-carrier scale
The weight and support needs of an F-35B make a small Second World War escort carrier a poor direct comparison for a modern ship.
