At least, the Defiant was very effective against bombers, if they were conserved, they might have been useful during the Battle of Britain. Surely, there's a worse aircraft?

The Defiant was taken out of service during the Battle of Britain as their losses were so heavy. The factories were making Spitfires and Hurricanes faster than the Germans were shooting them down, the problem was piolets as they take a time to train. The Defiant people were transferred to other fighter Squadrons
