By 1940 Britain had the worlds largest navy. The royal navy was located throughout the world yet it still had a very powerful home fleet. The German navy was unfunded and small. The Germans launched airraids on Britain, at first these where military target they aimed for. Yet the Germans then focused on civilian targets. Which allowed the British air forces to regroup and win the Battle of Britain.
