Midway Island is a location in Ace Combat: Joint Assault. An atoll in the North Pacific Ocean, it is an equidistant point between Asia and North America, and is historically known for the Battle of Midway, a major confrontation between the United States and Japan's navies during World War II. One of its largest islands was Sand Island, which housed a former US Navy airfield during the war.
During the Valahia Crisis, Midway Island was the site of a joint military exercise between Martinez Security, Japan Self-Defense Forces and the Seventh Fleet of the United States Navy, who intercepted a Valahia air force headed to Japan.After the discovery of the Golden Axe Plan, Fredric Burford and Antares Squadron used the Midway's airfield as their main base of operations, narrowly survived and repelled a bombing run from four Orgoi airborne carriers operated by the Golden Axe Plan Private Army.
- The Sand Island and its airfield were the basis for Sand Island Air Force Base from Ace Combat 5: The Unsung War.
