Lockheed Martin [NYSE: LMT] has 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).

Lockheed Martin's current DHIII is an open architecture system that consists of three key components: a light-weight, hand-launched, rugged air vehicle with a number of snap-on payloads (Plug and PlayloadsTM); a portable ground station; and a remote video terminal. The air vehicle's quiet operation and 360-degree optical turret provides the war fighter with stealthy, autonomous intelligence, surveillance and reconnaissance (ISR) capabilities. The system also includes programmable terrain avoidance and dynamic flight re-tasking options for the operator. The British Army has used DHIII extensively in both Afghanistan and Iraq.

The recent DHIII flight tests mark the first time a SIGINT payload has successfully flown onboard a small UAS platform. The new payload option will significantly expand the DHIII's surveillance capabilities by adding the ability to detect and locate sources of radio frequency emissions. The DHIII's new wing Flight testing of the new payload and wing design was conducted at the California National Guard's Camp Roberts and the Minnesota National Guard's Camp Ripley in April 2009.

Lockheed Martin anticipates that these new enhancements to the DHIII will become operational capabilities later this year.

"We are committed to providing new capabilities that vastly improve situational awareness and force protection," said John Nikolai, director of Electronic Products & Logistics at Lockheed Martin's Tactical Systems business. "We are proud of the flexibility that DHIII continues to demonstrate by enabling low-risk and rapid insertion of critical ISR capabilities."
