WASHINGTON -- August 12, 2013

At AUVSI – AeroVironment, Inc. (NASDAQ:AVAV) today announced that a recent
outdoor test flight of a solar-powered prototype version of the company’s
proven Puma AE™ small unmanned aircraft system (UAS), operating with the
company’s newest long-endurance battery, lasted 9 hours, 11 minutes –
significantly longer than the flight endurance of small UAS being used in the
field today.

AeroVironment is working with Alta Devices, a Sunnyvale, Calif. company that
provides flexible, portable power that can be embedded into any other
material, in the development of the solar Puma AE.

“This is a critical milestone with far-reaching implications for the many ways
small UAS can benefit military, public safety and commercial customers,” said
Roy Minson, AeroVironment senior vice president and general manager, Unmanned
Aircraft Systems (UAS). “The solar Puma AE is the latest example of
AeroVironment’s longstanding commitment to deliver important, innovative
solutions that meet our customers’ needs.

“Our integration of this cutting-edge technology dramatically increases Puma’s
current flight endurance using a clean, renewable power source,” Minson added.
“This development can give Puma AE customers significantly increased
capabilities that approach those of the next class of UAS at a much lower
acquisition and operating cost, and with much greater operational
flexibility.” AeroVironment’s new long endurance battery extends Puma AE’s
non-solar endurance to more than three hours. This means small UAS could be
used for longer missions over greater distances than previously possible.

Minson added that past solar solutions for powering small UAS were either too
heavy or did not produce enough power for long-range flight – or both.
“However,” he said, “the solar Puma AE technology can produce enough power,
while adding negligible weight, so that endurance is no longer an issue for
most customer missions.”

Using a proprietary and highly differentiated technology, Alta Devices
manufactures the world's thinnest and highest efficiency solar cells using
Gallium Arsenide. This technology significantly extends the battery life of
any application, in many cases eliminating the need to recharge from the grid
because it converts more light into electricity. Solar material like that used
in the development of the solar Puma AE incorporates a thin, mobile power
technology on a flexible substrate that has been independently certified by
the National Renewable Energy Laboratory (NREL) as world-records for both
single (28.8%) and dual (30.8%) junction solar cells.

Puma AE is a flexible, efficient and rugged hand-launched workhorse for
intelligence, surveillance and reconnaissance (ISR). This solar-power
enhancement makes it even more indispensable for U.S. and allied military, as
well as for domestic public safety applications, such as firefighting, law
enforcement, search and rescue, oil and gas field monitoring, and other
commercial needs.

The solar Puma AE configuration currently is in the research and development
phase. A production version is planned for early 2014.

The 13-pound Puma AE is fully waterproof, man-portable and can be assembled in
minutes, hand-launched, operated and recovered on sea or land by a team of two
people. It requires no infrastructure, such as runways, launching pads or
recovery devices. In addition, the system is quiet and operates autonomously,
providing persistent observation data.

Last month, AeroVironment received a “Restricted Category” rating for its Puma
AE small UAS from the Federal Aviation Administration. The first-of-its-kind
certificate permits operators to fly Puma AE for commercial missions in
regions of the Arctic.

About AeroVironment’s Family of Small UAS

RQ-11B Raven®, RQ-12 Wasp AE™, RQ-20A Puma™ and Shrike VTOL™ comprise
AeroVironment’s Family of Small Unmanned Aircraft Systems. Operating with a
common ground control system (GCS), this Family of Systems provides increased
capability to the warfighter that can give ground commanders the option of
selecting the appropriate aircraft based on the type of mission to be
performed. This increased capability has the potential to provide significant
force protection and force multiplication benefits to small tactical units and
security personnel. AeroVironment provides logistics services worldwide to
ensure a consistently high level of operational readiness and provides mission
services for customers requiring only the information its small UAS produce.
AeroVironment has delivered thousands of new and replacement small unmanned
air vehicles to customers within the United States and to more than twenty
international governments.

The Qube™ small UAS is tailored to search and rescue, first response, law
enforcement and other public safety missions. Small enough to fit easily in
the trunk of a car, the Qube system can be unpacked, assembled and ready for
flight in less than five minutes, giving the operator a rapidly deployable eye
in the sky at a fraction of the cost of manned aircraft and large unmanned
aircraft.
