Besides the FAF Gladiators, the Swedish Voluntary Air Force, responsible for the air defence of northernmost Finland during the later part of the Winter War, was also equipped with Gladiator fighters, known as J8s (Mk Is) and J8As (Mk IIs). The Flying Regiment F 19 arrived in Finnish Lapland on 10 January 1940 and remained there until the end of hostilities. It fielded 12 Gladiator Mk II fighters, two of which were lost during the fighting and five Hawker Hart dive bombers, plus a Raab-Katzenstein RK-26 liaison aircraft and a Junkers F.13 transport aircraft.[27] The aircraft belonged to and were crewed by the Swedish Air Force but flew with Finnish nationality markings.
