Ten of the aircraft were donated while the other 20 were bought by the FAF; all were delivered between 18 January and 16 February 1940, the first entering service on 2 February 1940.[25][26] The Finnish Gladiators served until 1945 but they were outclassed by modern Soviet fighters during the Continuation War and the aircraft was mostly used for reconnaissance from 1941. The Finnish Air Force obtained 45 aerial victories by 22 pilots with the aircraft during the Winter War and one victory during the Continuation War. Twelve Gladiators were lost in combat during the Winter War and three during the Continuation War.[25] Two pilots became aces with this aircraft: Oiva Tuominen (6.5 victories with Gladiators) and Paavo Berg (five victories).
