The Finns also received 20 half-completed ex-Yugoslavian Mk IV Blenheims captured by Germany, together with manufacturing tools and production equipment, as well as a huge variety of spare parts. Yugoslavia had ceased production of the Mk I and commenced a production run of Mk IVs just prior to the April 1941 invasion.
The Finnish Blenheims flew 423 missions during the Winter War, and close to 3,000 missions during the Continuation War and Lapland War. Blenheim machine-gunners also shot down eight Soviet aircraft. Thirty-seven Blenheims were lost in combat during the wars.
After the war, Finland was prohibited from flying bomber aircraft by the Paris Peace Treaty, with Finland's Blenheims being placed into storage in 1948. However, in 1951, five Blenheims were re-activated for use as target tugs, with the last flight of a Finnish Blenheim taking place on 20 May 1958.
