Design and development
The WM-21 was designed to replace the WM-16, which was considered unsuitable for operational service. The WM-21's structure was strengthened, and the aircraft received a new, more efficient wing set. A tailskid was fitted to allow for shorter landing runs on grass airfields. A conventional biplane, the Sólyom was powered by a 870 hp (649 kW) Weiss WM-K-14A radial engine. A total of 128 aircraft were built by three different factories, Manfred Weiss built 25, 43 by MAVAG and 60 by MWG.
The first aircraft entered service in 1939 with short-range reconnaissance units, although active during the 1940 dispute with Romania their first active operational use was during the Axis invasion of Yugoslavia in August 1941. From June 1941 they were used to support Hungarian Army units in Ukraine and then against Soviet partisans. Around 80 aircraft were also transferred to duties as trainers, as they were removed from operational use, until 1945.
