Were Royal Navy light fleet carriers built on merchant-ship lines?
Short answerNo. Escort carriers were merchant-derived, but light fleet carriers were naval-standard designs related to Unicorn.
NotesRoyal Navy light fleet carriers were naval-standard designs related to HMS Unicorn. Escort carriers came from merchant hulls or merchant-derived designs, which explains the frequent confusion between the two types. Welding helped accelerate construction and save weight, but it already had a place in earlier Royal Navy carrier construction. Its use therefore does not establish merchant origins. The light fleet carriers' accommodation arrangements also reflected the Fleet Air Arm's separation from the Royal Air Force.
