The following is a list of fleet aircraft carriers of the Royal Navy of the United Kingdom.
HMS Unicorn was an aircraft repair ship and light aircraft carrier; an "aircraft maintenance carrier".
The 1942 Design Light Fleet Carriers were designed and constructed by civilian shipyards to serve as an intermediate step between the expensive, full-size fleet aircraft carriers and the less expensive but limited-capability escort carriers. Perseus and Pioneer were modified to operate as maintenance carriers.
The 1942 design was modified to take more modern aircraft and these ships became the Majestic-class. Not completed until after the end of the war, most ended up purchased by other navies.
