ST. PETERSBURG, FL and ATLANTA, GA and COLUMBUS, GA -- (MARKET WIRE) -- 06/18/07 -- Cyber Defense Systems, Inc. (OTCBB: CYDF), a designer and developer of next generation unmanned aerial systems (UASs), announced today that the company has received an Experimental Airworthiness Certificate from the Federal Aviation Administration, the first for small hand-launched UASs under 100lbs in the United States, allowing the CyberBug(TM) Unmanned Aerial System to fly in the National Airspace System.

To date, the U.S. aviation agency has issued only twelve EACs for UAS operations in civil airspace, with Cyber Defense receiving the latest. Cyber Defense earned the right to fly in the NAS after successfully completing a CyberBug(TM) demonstration flight for FAA officials at a location in Pasco County, Florida on June 15th, 2007.

The CyberBug(TM) is a high tech asset for military, law enforcement and commercial applications. The unmanned air vehicles can be assembled in minutes and launched from an open area to provide instant aerial surveillance. The vehicles fly for up to an hour and transmit video and data to a portable ground control station. The CyberBug(TM) operator can safely monitor dangerous events, see around buildings, over hills and beyond line of sight. Applications include search and rescue, traffic monitoring, environmental, research, border patrol, drug interdiction and more.

Billy Robinson, president and chief executive officer of Cyber Defense Systems, called receipt of an FAA EAC a "significant company milestone," noting that this achievement was obtained "through a lot of hard work on the part of the CyberBug(TM) team and outstanding support from the FAA."

An EAC permits UAS flight operations in specified sections of the NAS. It also authorizes unmanned aircraft manufacturers to conduct research and development, crew training and marketing demonstration.
