Lockheed Martin-Led Industry Team Awarded Phase 3

PALMDALE, Calif., 04/27/2009 --

The Defense Advanced Research Projects Agency (DARPA) has selected Lockheed Martin [NYSE: LMT] as the systems integrator and Raytheon Company [NYSE: RTN] as the radar developer for Phase 3 of its Integrated Sensor is Structure (ISIS) program.

Under the contract valued at just under $400 million, Lockheed Martin will lead an industry team in the design, build, test and flight-demonstration of a one-third scale airship featuring Raytheon's new, low-power density radar. The autonomous flight test system will operate on station for 90 days, proving several key technologies with an anticipated total demonstration of one year.

"The development of high energy density power systems, an extremely lightweight radar solution and an advanced flexible composite material were necessary to make a stratospheric airship like ISIS possible," said Eric Hofstatter, Lockheed Martin ISIS program manager. "This is an extremely advanced machine that represents a dramatically different approach to persistent real-time intelligence gathering and to the overarching utility of airships."

Raytheon's ground-breaking radar capability is an integral component of the airship structural design. The active electronically scanned array antenna will transmit on UHF and X-band from within the airship.

"The operational goal for ISIS is to look for airborne and ground-based targets and to communicate directly with the battlefield from a single antenna for up to 10 years," said Michael Wechsberg, director of radio frequency systems programs for Raytheon Space and Airborne Systems.

The ISIS program will develop the core technologies necessary to demonstrate an extremely capable radar sensor package within the structure of a stratospheric airship, operating at approximately 70,000 feet. ISIS Phase 3 will demonstrate the next step to providing unblinking, mission-critical data to the war fighter from its continuous position on-station.
