OC-135

The OC-135 is an American observation aircraft. It is a modified WC-135B. The OC-135B modifications centre around four cameras installed in the rear of the aircraft. Since its primary mission is to take pictures, most of the installed equipment and systems provide direct support to the cameras and the camera operator. Work on the aircraft also included installing an auxiliary power unit, crew luggage compartment, sensor operator console, flight following console and upgraded avionics. The interior seats 38 people including: the cockpit crew, aircraft maintenance crew, foreign country representatives and crew members from the Department of Defence's On-Site Inspection Agency. Cameras installed include one vertical and two oblique KS-87 framing cameras used for low altitude photography approximately 3,000 feet above the ground, and one KA-91 pan camera, which pans from side to side to provide a wide sweep for each picture, used for high altitude photography at approximately 35,000 feet. The Miletus camera annotation
system processes navigational, altitude, time and camera signals to annotate each picture with correct position, altitude, time, roll angle and other information. In addition, this system records every picture taken according to camera, frame and navigational position and downloads this data to a 3.5-inch floppy disk. A keyboard with trackball is the input device for operation of this system. Two Barco 12-inch VGA colour monitors display camera annotation and other camera data on screen for the sensor operator and observer use.
