Lighter Than Air Systems Provides Initial Aerostat Launcher System and 
Aerostats to BAE Systems to Support the U.S. Army Space and
Missile Defense Command 
Initial Complete Trailer-Mounted System and Six Aerostats Delivered 
KENNEDY SPACE CENTER, FL -- (Marketwired) -- 04/16/13 --  World
Surveillance Group Inc. (OTCQB: WSGI), a developer of
lighter-than-air aerostats and unmanned aerial systems, announced
today that its wholly owned subsidiary, Lighter Than Air Systems
Corp. ("LTAS"), has provided the initial trailer-mounted aerostat
launcher system and six aerostats to BAE Systems to support the U.S.
Army Space and Missile Defense Command ("SMDC"). The LTAS self
contained, compact, trailer-mounted aerostat launcher system and
aerostats have been delivered and are undergoing testing and
evaluation for various mission profiles to support and enhance
critical communications for the Army. Utilizing the LTAS aerostats,
the SMDC is able to extend encrypted communications up to
approximately 20 miles using standard battlefield radios. LTAS
expects to deliver the second aerostat launcher system to BAE Systems
in the second quarter 2013. 
The LTAS aerostat launcher systems are custom designed, engineered
and manufactured to provide rapid communications and intelligence,
surveillance, and reconnaissance ("ISR") capabilities for government
and commercial applications. The LTAS aerostat launcher systems are
proprietary, in-house designed, turn-key systems that are self
contained and mounted to a compact trailer for use with various
military vehicles. The LTAS aerostat systems include fixed and remote
controls, custom software and electronics, and self contained helium
storage with rapid inflation and deflation systems for simplified
user operation.  
The LTAS aerostat launcher systems are engineered to provide
significant benefits over competing systems, including reduced
maintenance and overall operation costs, smaller footprint for
operations, reduced operators required to manage the aerostat,
decreased time for inflation/deflation, faster launch and recovery,
and a simplified process.  
WSGI President and CEO, Glenn D. Estrella, stated, "We are excited by
this opportunity to provide our systems and aerostats to customers
who can witness their effectiveness at prov
iding critical
communications solutions to support the Army. We are committed to
continually improving our products to meet the stated needs of our
customers so as to deliver proven turn-key solutions that provide the
customer's desired results. We intend to continue to execute on our
business plan as we pursue a leadership position in the compact,
tactical aerostat market."
