IMINT — imagery intelligence — is intelligence derived from photographic, infrared, radar, and other imaging systems carried aboard satellites, aircraft, and unmanned platforms. The discipline emerged from First World War aerial reconnaissance, expanded substantially during the Second World War, and was transformed by Cold War overhead-collection programmes: the U-2 reconnaissance aircraft (operational 1956), the CORONA satellite series (1959–1972), and the successor KEYHOLE family of imaging satellites operated by the National Reconnaissance Office, established 1961 and acknowledged 1992.

The October 1962 Cuban Missile Crisis is the canonical demonstration of strategic IMINT. U-2 photography of the San Cristóbal site in Cuba on 14 October produced unambiguous evidence of Soviet medium-range ballistic missile installations, and the photographic interpretation cycle that followed gave the Kennedy administration a usable intelligence picture during the thirteen days of crisis. The dossier on the crisis treats this episode in detail; subsequent IMINT work on Soviet strategic forces continued throughout the Cold War as the basis for arms-control verification under the SALT and START agreements.

The institutional landscape of US IMINT has shifted substantially. Photographic interpretation, originally done by CIA's National Photographic Interpretation Center, was consolidated in 1996 into the National Imagery and Mapping Agency, which became the National Geospatial-Intelligence Agency in 2003. The National Reconnaissance Office operates the satellites; the NGA processes and analyses the imagery. The advent of high-resolution commercial satellite imagery — operated by Maxar, Planet Labs, and Airbus — has further changed the discipline by giving non-state actors, journalists, and academic researchers direct access to imagery products that were once exclusively classified.

IMINT has its limits. Photographs depict surface features, not intentions; radar and electro-optical sensors can identify hardware, but rarely orders. The discipline is at its strongest when paired with HUMINT or SIGINT — Penkovsky's documentary reporting on Soviet missile specifications during the Cuban Missile Crisis made the U-2 imagery legible in a way it would not otherwise have been.
