ABSTRACT
This chapter considers imagery intelligence. Permanent record imagery is intelligence from inaccessible areas which can be studied, compared with previous imagery, and restudied. Remote sensing products include intelligence on the disposition, composition, and movement of enemy forces, enemy installations, lines of communications, and electromagnetic emitters based upon the supported unit's essential elements of information. After completing the mission, the pilot debriefs and the imagery is processed and analyzed in the air force's processing and interpretation system, the mobile army ground imagery interpretation center, or the marine air-ground intelligence system. The major post-Korean remote sensing development was the first U-2 flight across Soviet airpace on July 4, 1956. The mission of the 23rd Special Warfare Aviation Detachment's Mohawks was to support the Republic of Vietnam Army with observation and remote sensing. The SR-71A Blackbird, which served over Vietnam, was also developed by Lockheed as a long-range, advanced, strategic remote sensing aircraft, and is America's primary strategic remote sensing aircraft.
