Background
The Gloster Gladiator was the last biplane fighter to be used in large numbers by the Royal Air Force before the arrival of monoplane fighters, such as the Hurricane and Spitfire. In addition, Gladiators served the Royal Navy as the Sea Gladiator, and were exported to other countries, including Latvia, Lithuania, China, Sweden, Belgium, Finland, Norway, Iraq, Erie, Portugal, Egypt, and Greece. The British examples were withdrawn from first line service by 1941, although they soldiered on in other countries well after that.
