The United States Intelligence Community (IC) is the set of intelligence agencies of the United States government. Since are coordinated by the Office of the Director of National Intelligence (DNI) since April 2005, and, from 1947 until then, by the Director of Central Intelligence (DCI). The DCI both coordinated the IC and headed the Central Intelligence Agency, but, after the creation of the DNI, the title changed to Director of the Central Intelligence Agency and was responsible for the CIA alone.

It is generally said there are 16 intelligence agencies, but some have fairly autonomous components, and there is at least one, and probably more organizations and components whose existence is not public.


In the Office of the DNI are a number of interagency centers and working groups.

Overview of functions

The matrix below is organized by intelligence disciplines. Some agencies collect information only, some analyze it only, and others do both.

Need to put in service TECHINT

TENCAP may need to be mentioned; the whole strategic vs. technical issue is a mess.

Source type Collection Processing Analysis
SIGINT NRO, NSA/CSS[1], Special Collection Service (SCS) [2] NSA, CIA, DIA, Army, Air Force, Navy, Marines[3] Analytic agencies[4]
IMINT NRO NGA Analytic agencies
MASINT NRO, NSA/CSS, SCS, Department of Energy DIA Analytic agencies
HUMINT CIA/NCS, FBI CIA, FBI, ODNI Analytic agencies
TECHINT Military DIA Analytic agencies
OSINT ODNI Open Source Center ODNI Analytic agencies
FININT Treasury, CIA CIA, FBI, ODNI Analytic agencies
MEDINT DIA, CIA CIA, FBI, ODNI Analytic agencies

Not quite sure whether the Center for MASINT Studies and Research, Air Force Institute of Technology, qualifies as a major operating agency.


  1. CSS includes Service Cryptologic Elements
  2. May be renamed; has been called CIA Division D. Responsible for placing SIGINT and MASINT sensors in denied areas
  3. Service agencies especially with respect to electronic warfare affecting their tactics
  4. In principle, NRO and NSA are collection (and perhaps) processing only and do not do analysis that produces finished intelligence. Other agencies do analysis
