The United System Peacekeeping Navy, commonly known as the Peacekeepers, are an intergovernmental space based military force fielded by an alliance of the United States, Bharat, the United Kingdom, Gran México, France, and many smaller Eurasian Bloc countries and allies. Both the United States and Bharat have their own significant forces of Naval Rated Ships and contribute with older ships and materiel, using the Peacekeepers for missions where avoiding entanglement and conferring the optics of international legitimacy are required.

The organisation was formed in 102 BFC to counter the increasing coordination between Greater Zhōngguó and Dominio (and to a lesser extent Türkiye and the Fatimid Trade Caliphate) in international civilian affairs such as policing and enforcing trade conditions on off Earth colonies, and it has now grown to field a larger number of rated ships than GZ. The Peacekeepers draw materiel from a number of specialised manufacturing hubs such as Drone Valley, and often hire training and intelligence facilities from the Constellis Group such as the White Sands Missile Range and the Panopticon Relay.
