The
aircraft is designed to support covert operations, utilizing its
low aural signature and low visual observability are essentially
inaudible at distances greater than 33 meters (100 ft), allowing
covert operations without compromising surveillance techniques or
endangering the warfighter. The aircraft is equipped with interchangeable
two-axis stabilized turrets mounting three types of payloads. Optional
payloads include a narrow-field of view video camera providing detection,
recognition and identification of targets at relatively long range.
Another
payload can carry three sensors - side-looking EO/IR module combining
color CCD and low-light B/W camera and Long-wave Infrared imager
(LWIR), enabling continuous operations in day, night and under limited
visibility conditions. The low-light B/W imager is uniquely useful
at crossover times, at dusk and dawn, when neither color nor infrared
imagers can detect and monitor activities adequately. A third module
uses an infrared imager coupled with an infrared illuminator, improving
the system's performance when operating in moonless or cloudy nights.
The IR illuminator can be seen only with night vision equipment
also be used to mark target positions, guide friendly forces toward
targets of interest or away from hazardous areas.
Desert Hawk III UPgrades & Enhancements:
In April 2009 Lockheed Martin successfully completed flight testing of a new signals intelligence (SIGINT) payload and a next generation wing design that will provide enhanced capabilities for the company's small Desert Hawk III (DHIII) Unmanned Aircraft System (UAS). By 2009 the British Army have used DHIII extensively in both Afghanistan and Iraq.
The recent flight tested enhancements mark the first time a SIGINT payload has successfully flown onboard a small UAS platform. The new payload option to become available for operational use later this year will significantly expand the Desert Hawk's surveillance capabilities by adding the ability to detect and locate sources of radio frequency emissions.
