"Universal wing" became one size fits all for weaponry

The FHC’s Spitfire Mk. Vc has what is called a “universal wing.” The wing design is less complex than earlier models and thus was able to be build quicker. One interesting aspect of the new wing was it allowed squadrons to pick the types of weaponry they would like to fly with on a particular mission. The universal wing could carry eight .303 machine guns, four 20 mm cannons, or a mixture of the two. The FHC’s Spitfire is currently set up with two cannons and four machine guns. The wing also allowed the plane to carry two 250-pound bombs in wing-mounts racks (“bomb carriers.”)
