Long-wave infrared (LWIR) cameras, sometimes called "far-infrared", operate at 8 to 12 μm and can see heat sources, such as hot engine parts or human body heat, several kilometers away. Longer-distance viewing is made more difficult with LWIR because the infrared light is absorbed , scattered , and refracted by air and by water vapor.
[2] [3] The infrared cameras each featured a seven-position filter wheel feeding into a 256×256 pixel InSb focal-plane array; [2] the SWIR camera operated at 2.5 to 3.3 μm wavelengths while the MWIR camera operated from 3.5 to 4.5 μm. [6] The VIS used a 499×768 pixel CCD detector operating at 0.5 to 0.8 μm.
It is primarily used as a small transport aircraft by Air Force Special Operations Command. UV-18B Twin Otter: Canada: utility transport 3 [5] STOL capable aircraft.It is primarily used as a training aircraft for parachute troops at the military academy.

The effect of reduction in friction between air and aircraft does not compensate for the better transmission of infrared radiation. Therefore, infrared detection ranges are longer at high altitudes. At high altitudes, temperatures range from −30 to −50 °C - which provide better contrast between aircraft temperature and background temperature.
Eglin AFB Site C-6 is a United States Space Force radar station which houses the AN/FPS-85 phased array radar, associated computer processing system(s), and radar control equipment designed and constructed for the U.S. Air Force by the Bendix Communications Division, Bendix Corporation.
The Hurricane Hunters of the Air Force Reserve are distinct from those of the Department of Commerce's NOAA Hurricane Hunters, based at Lakeland Linder International Airport, Florida, [4] who use a pair of Lockheed WP-3D Orion and a Gulfstream IV-SP aircraft to also fly weather reconnaissance, data collection and scientific research missions.
Directional Infrared Counter Measures (DIRCM) are a class of anti-missile systems produced to protect aircraft from infrared homing missiles, primarily MANPADS and similar simple systems. Earlier infrared countermeasures like flares or hot block systems that produce random flashes of IR light are semi- or omnidirectional.
Cast Glance is a gyrostabilized optical instrument used by the United States Navy and United States Air Force. It is an airborne system that is used by Air Test and Evaluation Squadron 30 (VX-30) on board the Lockheed NP-3D variant of the P-3 Orion. The system consists of a moving gyro-stabilised mirror with fixed optics, two fixed cameras and ...
