The International Union Spacy, also known as the IU Spacy or simply the Union Spacy, is the unified spaceborne military arm of the International Union of Earth ( IUE ). A transnational force formed in response to escalating extraterrestrial threats. Composed of elite pilots, naval officers, and engineers from across the Union’s member states, IU Spacy is tasked with defending Earth, securing orbital territory, and leading humanity’s expansion beyond the atmosphere.

Operating advanced Prototech-enhanced ships, IU Spacy blends alien and human technologies into powerful war machines fueled by Protosource. Its structure includes orbital defense fleets, expeditionary task forces, and research units dedicated to recovering lost technology.

The IU Spacy’s plans are the most ambitious of mankind to date, undertaking the Union Expeditionary Fleet—which seeks to reach deep space and uncover the origins of the Protosource Matrix hidden on Earth.
