Mission & acquisition strategy

As designated in the EO 14299, the Army serves as the DoW Executive Agent (EA) for installation and operational nuclear energy. The Assistant Secretary of the Army for Installations, Energy and Environment (ASA-IEE) executes the responsibilities necessary using the existing EA Agreement on behalf of all of the Services, including expanding the Army Nuclear Energy (NEO) Office and Janus Program Office to lead and support the EA office functions under the ASA-IEE, establishing and executing the program of record for both installation and operational nuclear energy.

Costs related to this MPP program proposal are estimated based on responsibilities for running a program management office for multiple power production plants that will provide reliable power and key mission energy security on U.S. military installations, reducing financial risks to selective manufacturers. MPPs costs are estimates for milestone payment for design maturity, licensing and regulatory processes, investment towards key long lead components, and heavy manufacturing capabilities.
