 The aircraft was still in the prototype stage when the war ended and this also meant that the funds allocated for the project decreased.The "Pyörremyrsky" prototype was grounded after only some 30 hours of flying and the programme terminated as no funds were available for the purchase of new aircraft for the Finnish Air Force and sufficient Bf 109Gs remained in service to equip the fighter force that was permitted under the Armistice terms.The PM-1 was removed from FAF lists on 1 April 1953.
