 | | Seaplane tenders, such as HMS Engadine, out of frontline use after the 1920s when carriers capable of handling conventional airplanes came into fleets and the superiority of landplanes over seaplanes in naval operations became firmly established. |
 | | However, the vulnerability of carriers to traditional battleships was quickly illustrated by the sinking of HMS Glorious by German battlecruisers during the Norwegian campaign in 1940. |
