A ground attack plane needs a cannon. Hurricane had some rifle calibre machineguns. For ground attack Russians had Lagg-3s and I-16s with cannons and rocket launchers. What they needed in 1941 is a good fighter plane. Pilots didnt like Hurricane. Government didnt listen. P-40s and P-39s on the other hand were well respected and much appreciated airplanes on the East. Hurricane was a nonsense.
