Been rereading Brit author Alexander Fullerton’s World War II convoy novels in which German submarines sank more than actually got through. And if the subs didn’t get them, the Stuka dive bombers did.
The most reliable aerial weapon the Brits had to protect the convoys was the Supermarine version of the Spitfire, with its four-blade prop. Always have liked the look of those wide wings. They mounted eight machine guns. They needed so many against malfunctions, such as the freezing of the outer ones at high altitude.
