    The Gladiator was designed in response to Air Ministry specification F.7/30 but after lengthy delays the Gladiator was put into production just in time to become obsolete. The type soldiered on for quite some time, providing fighter support for secondary theaters. Gladiators of the Auxillery Air Force intercepted the first bombing raid over England in September, 1939. Aircraft that survived the sinking of the H.M.S. Glorious operated from a frozen lake in Norway against the Luftwaffe and three Sea Gladiators helped defend Malta from the Regia Aeronautica from June 11, 1940.
   The Mark II incorporated desert filters, automatic mixture control and an electric starter powered by an internal battery. The Sea Gladiator was equipped with full carrier equipment.
