Cyber Defense Subsidiary Techsphere Systems to Build New "BULLET" Airship Technology for Mid Altitudes; New Prototype Test Flight Successful

ATLANTA, GA and COLUMBUS, GA--(Marketwire - September 28, 2007) - Cyber Defense Systems, Inc. (OTCBB: CYDF), a designer and developer of next generation unmanned aerial vehicles (UAVs), and its wholly owned subsidiary Techsphere Systems International, Inc. (TSI), a designer, developer and manufacturer of manned and unmanned airships, announced today that it will build two new Mid Altitude "BULLET" Airships.

Under the exclusive global technology license with 21st Century Airships, Techsphere will begin manufacturing two "BULLET" airships designed for altitudes of 20,000 and 40,000 feet capability with a minimum of 48 hours flight duration with estimated speeds up to 60 knots with a manned or unmanned configuration. Recent wind tunnel tests by 21st Century confirmed the design and speed estimates.

The initial test flights were exceptional utilizing a fly by wire thrust vectoring capability. "Just imagine being able to fly straight up and down, turn on its axis, and fly sideways with an easy touch of a joystick," stated Hokan Colting of 21st Century.

The airship tested is approximately 120 feet long, cylinder shaped with two distinct pointed end caps with four engines mounted port and starboard in the fore and aft positions on the cylinder structure.

Techsphere will be utilizing the majority of the patented technologies from the spherical technology with the new "BULLET" version for Mid Altitudes. "The SA-60 spherical airships will continue to be our bread and butter for the 0 to 10,000 feet altitude capability. We are addressing the higher winds between 10,000 feet to 40,000 feet altitudes with a new shape for drag reduction, longer duration of flight, higher speeds with the maneuverability characteristics of the 'Sphere' technology," stated Mike Lawson, CEO of Techsphere.

The "BULLET" test flights will continue later this year with the second prototype near completion.
