AeroVironment Inc. (AVAV) May 27 announced it has been awarded a six month, $636,000 Phase II contract by the Defense Advanced Research Projects Agency (DARPA) to design and build a flying prototype for the Nano Air Vehicle (NAV) program.

AV completed a preliminary design review at the end of its Phase I, $1.7 million program.

Phase II will culminate with the demonstration of a rudimentary, three-inch flapping-wing air vehicle system. Following a successful demonstration, DARPA has the option to extend the program for an additional 18 months, which could increase the Phase II contract value.

The NAV program was initiated by DARPA to develop a new class of air vehicles capable of indoor and outdoor operations. Employing biological mimicry at an extremely small scale, this unconventional aircraft is designed to provide new military reconnaissance capabilities in urban environments.

AV’s NAV is designed to weigh no more than 10 grams and have the ability to carry a payload of up to two grams. AV’s NAV team also developed the Black Widow and Wasp MAVs for DARPA.

“Our Raven and Wasp III UAS began as early development programs similar to the NAV program, and now help protect the lives and enhance the operational effectiveness of warfighters and first responders,” John Grabowsky, AV executive vice president and general manager of unmanned aircraft systems, said. “The NAV program represents the early development of a revolutionary new class of UAS that could eventually provide valuable new capabilities to our customers,” Grabowsky added.

U.S. armed forces use AV’s hand-launched UAS extensively for missions such as base security, route reconnaissance, mission planning, battle damage assessment and force protection. The Army reported that its Ravens were flown for approximately 150,000 combat hours in 2007. AV has delivered over 9,000 small unmanned aircraft to date, including Raven, Wasp and Puma.
