Bombing Hitler's Supergun Preview
Spring 1943. World War II is slowly beginning to turn in favor of the Allied forces. But, growing desperate, Hitler hatches plans for a diabolical weapon: a bank of “superguns" housed in a massive underground complex in Nazi-occupied northern France. Together the guns would be able to pump 300 heavy high explosive shells into downtown London every hour—a target 100 miles away.
