Sensors
The U-2's modular payload design allows the aircraft to be reconfigured to perform various missions which include; mapping studies, atmospheric sampling, and collection of crop and land management photographic data for the Department of Energy. The U-2 is capable of collecting multi-sensor photo, electro-optic, infrared and radar imagery, as well as performing other types of reconnaissance functions. An Air Force initiative following Desert Storm demonstrated the ability to locate relocatable targets from the U-2 all weather reconnaissance platform and transfer the data to a precision weapon platform within minutes enabling accurate targeting among multiple items.
The HR-329 (H-cam) uses a high resolution, gyro-stabilized framing system with a 66-inch focal length and folded optical path. Traditionally, the H-cam operates at an angle to provide greater coverage. During Desert Storm, planners experimented with the camera aimed straight down. The detail and clarity impressed planners and amazed theater commanders. Commanders were disappointed, however, that the system could not cover a greater range and still maintain the same detail and clarity. Although the H-cam imagery is especially useful for targeting, battle damage and order-of-battle assessment, targets must be preselected and the technicians must process the film after the aircraft lands.6.
The Intelligence Reconnaissance Imagery System III (IRIS-III) is an optical imagery system that uses a high resolution, panoramic camera with a 24-inch focal length. Employing a folded optical path system mounted on a rotating optical bar assembly, the IRIS-III laterally scans through 140 degrees of the total viewing area. This camera covers a 32-nautical-mile swath on both sides of the aircraft. The IRIS-III provides wider "synoptic" coverage than the H-cam, but it does not have the resolution or NIIRS quality.
