The IPEA operate independently of NERV. They are in charge of the Eva containment facility that Unit-02 is placed within under the terms of the Vatican Treaty. Given that Unit-02 was later sortied against the 10th Angel, with Mari Makinami Illustrious as pilot and the facility's technicians assisting her, IPEA may also possess independent power to mobilize Evangelion units. Provisional Unit-05's boot-up screen indicates that the subsystem is of IPEA manufacture, suggesting that IPEA also plays a role in the preparation of at least some Eva units.
