Waives any immunity of the United States with respect to such laws as applied to DOD and any defense-related agency. Provides for administrative enforcement actions.

Requires the Secretary of Defense, for each weapon system for which congressional budget justification is required, to ensure that all development and procurement decisions comply with the National Environmental Policy Act of 1969.
