Multinational Force
Operation Olympic Defender

Multinational Force Operation OLYMPIC DEFENDER (MNF OOD) globally integrates military spacepower, enables Joint and Combined Forces, deters aggression, and if necessary, defeats adversaries in order to retain military advantage.

The multinational force represents a shared commitment among the closest partners in space to ensure space remains a domain that benefits all of humanity. Originally established in 2013 under U.S. Strategic Command, MNF OOD has expanded to a multinational effort that focuses to optimize space operations, improve mission assurance, enhance resilience of space-based systems, synchronize efforts to strengthen deterrence against hostile actors and reduce the spread of debris orbiting the Earth.

MNF OOD operates under a Joint Staff order that provides the strategic framework through which the United States operates, secures, and defends the space domain with participating nations -- Australia, Canada, the United Kingdom, France, Germany, and New Zealand.  The multinational force formally achieved seven-nation membership and declared Initial Operating Capability in April 2025.

Australia, joined in 2020

France, joined in 2024
Germany, joined in 2024
New Zealand, joined in 2025
United Kingdom, joined in 2020

Participating nations collectively set five well-defined objectives required to achieve Initial Operating Capability (IOC), which the MNF-OOD Commander approved.

These objectives included collective concepts of operations for Space Domain Awareness, a mutually agreed upon combined operational framework, a defined scope of national space input to the MNF, a synchronized and deconflicted means of consistent and reliable communications between nations, enabled to convey national-level inputs to the MNF authoritatively, and the development and approval of a Campaign Plan.
