In early 1941, the United States had yet to enter into World War II, but weapons and warplanes were already a topic of national interest. One of those planes was the F4F-3 Wildcat, which the Naval Air Force deployed to monitor the coasts. The fighter, which graced the February 1941 cover of Popular Science, could drop 100-pound bombs while flying at speeds greater than 250 mph. As we wrote then, "Perhaps our patrol bombers and flying fortresses can't send capital ships with heavy deck armor to the bottom, but they can certainly send them to dry dock, back where they came from." Aviation technology has advanced significantly in the 70 years since World War II, and it stands to change even more. Future air battles will likely be fought by unmanned craft carrying much heavier artillery. Read about the weaponry, airborne and otherwise, being developed for new global conflicts here.
