Maybe putting a Griffon in it plus some cannon in the wings would've helped it...Defiants did great work in the initial role starting the Nightfighting War....if only they had got underneath the German bombers and let-strip with those 4x .303's, like the German 'Shrage Musik' installation in their nightfighters....Firing forwards in the Defiant, ruined the pilot's night vision from the gunflash, but they got the Allies started, along with the Hurricanes searchlights, until radar in Blenheims took it a step further.....
