Flak bursts blanket the skies above USS Enterprise (CV-6) during the Battle of Santa Cruz, October 26th, 1942. In the distant background the battleship USS South Dakota (BB-57) can be seen, as well as two destroyers. Enterprise is credited with downing 46 Japanese aircraft by AA fire, and South Dakota is credited with 26. This outstanding success is often attributed to the recent installation of the new 40mm Bofors anti-aircraft gun.
