A recently revised Defense Department regulation (pdf) provides new detail on the preparation of the annual intelligence budget request, and on the documentation needed to support it.
The U.S. intelligence budget is comprised of two spending “aggregations”: the National Intelligence Program (NIP) and the Military Intelligence Program (MIP). (This configuration replaced the former National Foreign Intelligence Program, Joint Military Intelligence Program, and Tactical Intelligence and Related Activities.)
The NIP budget, which totaled $43.5 billion in 2007 according to last week’s official disclosure, funds intelligence to support national policy makers. The MIP budget, which probably amounts to at least another $10 billion, supports the Secretary of Defense, the military services, and military commanders in the field.
In practice, the distinction between the NIP and the MIP is not crystal clear, and several large “national” intelligence agencies — including NSA, DIA, NGA, NRO — also receive funding through the MIP.
A Defense Department Financial Management Regulation on “Intelligence Programs/Activities,” dated June 2007, presents the definitions of the intelligence budget aggregations, explains their classification levels, and describes the documentation that must be submitted to Congress to justify their appropriations.
