Check Google or elsewhere before I do. The Poles flew either Hurricanes or Spitfires, as well as what they had from their original Polish Air Force (perhaps P 39 Aercobras).
I’ll get back here with some infor on this issue.
I’m backkkkk!
Poles flew their own PZL P.11 and P.7 in Poland at the beginning of the war. Took some to other countries with the fall of their country.
Flew French Caudron C 714 and MS 406 fighters.
Flew British Hawker Hurricanes (300 - 303 Squadrons). Then Got Spitfires and P 51 Mustangs.
British nightfighters: Defiants, Beaufighters and Mosquitoes.
In Russia they flew Yak 1 and Yak 9’s.
Best records were obtained in the Hurricanes and Spitfires during the Battle of Britain and over France.
Google “Polish Air Force in WW2” and you’ll get a lot of information on what they flew and how well they performed.
Extremely brave men.
