Response Plan Blue Zero

Response Plan Blue Zero was a UO military strategy developed formulated as a response to a hypothetical Anvilstrike situation, where Bacterian forces would begin attacking UO targets. It included an evacuation of the government to a hidden location on the outskirts of colonized space, as well as the full mobilization of UOSF space assets, primarily Task Force Orbeus, against the Bacterian fleet.

Such a situation eventually did materialize at the beginning of the First Bacterian War and the Siege of Aldaain, as the Bacterian motherships opened fire on the cities below and deployed devastating biological weapons.

The military preparations undertaken by UOAF proved to be woefully inadequate against the full strength of the Bacterian war machine, and the evacuation procedures of key personnel were only partially successful. However, the Overhemmo was able to escape Bacterian capture. Relocation of the government to a remote, unannounced location was part of the Anvilstrike Protocols, which eventually resulted in the UO Emergency Government setting up operations at a remote mining outpost, nicknamed The Refuge.
