While the NRO is a DOD agency, itis staffed by both DOD and CIA personnel. The National Geospatial-Intelligence Agency

The NGA, established in 1996 and originally known as the National Imagery and Mapping Agency (NIMA), provides geospatial intelligence -- imagery, imagery intelligence, and geospatialdata and information to DOD users and other officials responsible for national security. He is to "exercise authority, direction, and control"over DIA, NGA, the NRO, NSA, and other agencies. Impetus for Reform

In the aftermath of the attacks of September 11, 2001, a number of observers as well as the JointInquiry of the two congressional intelligence committees and the 9/11 Commission, concluded thatthe organization and management of the Intelligence Community was inadequate and that, as aresult, the DCI was unable to ensure that crucial information about the 9/11 plot was shared withanalysts who might have been able to identify the threat in advance. So sustaining the existing relationship, we think, is essential." P.L. The legislation was approved by thePresident on December 17, 2004. The conference report for S. 2845 authorized the DNI to
provide guidance for National Intelligence Program budget to heads of departments containing intelligence organizations;
"develop and determine" an annual consolidated National Intelligence Programbudget;
present National Intelligence Program budget to the President for approval(together with dissenting comments from heads of departments containing intelligenceorganizations); 
participate in the development by the Secretary of Defense of the annualbudgets for DOD-wide and tactical military intelligence programs;
ensure the "effective execution" of annual intelligencebudgets;
direct the allotment or allocation of appropriations through the heads ofdepartments containing intelligence agencies or organization
provide "exclusive direction" to the Office of Management and Budget (OMB)regarding apportionment and subsequent allocations of appropriated funds;
transfer or reprogram funds from one program in the National IntelligenceProgram to another (with OMB approval and subject to other restrictions);
transfer personnel from one intelligence agency to another for up to two years(under certain conditions). (38)
Taken together, these authorities will provide the DNI with significantly greater budgetary authorities than possessed by the DCI. In particular, provisions authorizing the DNI to directallocations and allotments of appropriated funds gives the DNI significant leverage in the acquisitionand program management efforts of intelligence agencies in DOD. Moreover, the final version of the legislation includes a provision (Section 1018) that requires the President to issue guidelines to ensure the effective implementation of authorities granted to theDNI, the Director of the OMB, and cabinet heads "in a manner that maintains, consistent with theprovisions of this act, the statutory responsibilities of the head of the departments of the UnitedStates Government with respect to such departments." The guidelines are to be issued within 120days of the appointment of the first DNI. 108-458 difficult. Nevertheless, the requirementfor close coordination between the DNI and DOD agencies will remain.
Although the Central Intelligence Agency (CIA) is the best known member of the Intelligence Community, the bulk of the nation's intelligence effort is undertaken by the intelligence agencies ofthe Department of Defense (DOD). In particular, the National Security Agency (NSA), the NationalReconnaissance Office (NRO), and the National Geospatial-Intelligence Agency (NGA) (formerlyknown as the National Imagery and Mapping Agency (NIMA)) are major collectors of informationfor DOD and non-DOD consumers and absorb a large percentage of the annual intelligence budget. (The Defense Intelligence Agency (DIA), albeit a large and important component of the IntelligenceCommunity, is more directly focused on DOD requirements.)
Some Members of Congress and independent commissions, most recently the National Commission on Terrorist Attacks Upon the United States, the 9/11 Commission, have argued thata lack of coordination among intelligence agencies contributed to the failure to provide warning ofthe terrorist attacks of September 2001. In response, in December 2004 Congress passed intelligencereform legislation ( P.L. 108-458 ) that modifies the existing organization of the IntelligenceCommunity and establishes more centralized leadership under a newly created Director of NationalIntelligence (DNI).
As the legislation was being debated in the fall of 2004, attention focused on the extent of the budgetary and administrative authorities to be assigned to the DNI. Significant concerns wereexpressed by DOD officials, some Members of Congress, and various outside observers thatproviding the DNI with greater authority and control of intelligence agencies in DOD couldjeopardize the increasingly close relationship between these agencies and the operating militaryforces.
The conference committee on intelligence reform legislation ( S. 2845 ) addressed these concerns with language that gave the DNI substantial authorities over intelligence budgets, butnot operational control over their activities. The final version of the legislation also provided thatthe details of budgetary authorities to be exercised by the DNI and other cabinet officers be workedout in accordance with guidelines to be issued by the President after the DNI is appointed.
