F-4Gs were used by both the Osean Air Defense Force and the Yuktobanian Air Force during the Circum-Pacific War. A notable pilot was the former captain of Wardog Squadron, Jack Bartlett. Another notable pilot was the Yuktobanian ace "Mindripper".
The F-4G was made available through Wernher and Noah Enterprises's Advanced Automated Aviation Plants. The United Nations Forces and its mercenary pilots were able to use these blueprints to purchase their own F-4Gs during Operation Eternal Liberation.
