Argus One Testing to Begin August 23, 2011

World Surveillance Group Inc, a developer of lighter-than-air unmanned aerial vehicles (“UAVs”) and related technologies, announced today that the Company has confirmed the schedule for the first round of flight testing of its Argus One UAV at the U.S. Army’s proving ground facilities in Yuma, Arizona. The flight exercises, which are focused on the aerodynamic and free flight maneuvering of the airship, will commence on August 23, 2011 and are expected to continue for several days.

In preparation for the Yuma tests, the Argus One UAV successfully completed “final flight check” tethered test flights on August 15, 2011 at the Easton, Maryland airport under tower control. Following these test flights, the Argus One has been prepared and packaged for its transportation out to the Yuma proving ground facilities. Once deflated, the Argus One UAV fits in a standard size shipping crate for easy storage and transportation even to remote locations.

Under a contract from Space Florida, an independent special district, body politic and corporate, and subdivision of the State of Florida, following the conclusion of the Yuma flight test exercises, the Company will present the results of the Yuma flight exercises to Space Florida in a performance data package.
