For Immediate Release

GKN Aerospace gains first development contract for 'Smart
Shaded bullet resistant windows   from the US Department of
Defense.

GKN Aerospace is exhibiting at DSEI, London, Sept 8   11,
2009 (Stand 791-UK Pavilion) and at AUSA, Washington DC,
5   7 October 2009.

GKN Aerospace has been awarded a $425,000 contract by the
Combating Terrorism Technical Support Office (CTTSO) of the
United States Department of Defense to develop instantly
dimmable bullet resistant windows.

The development programme will combine GKN Aerospace's
bullet resistant glazing expertise with 'suspended particle
device' (SPD-SmartGlassTM) technology from Research
Frontiers Inc. GKN Aerospace is licensed by Research Frontiers
to use SPD-SmartTM technology to develop armoured glass
products that will also offer vehicle occupants instant
'on-demand' light control and attenuation, privacy, and
protection from heat, glare, and ultraviolet (UV) light
penetration.

Dr William Fischer, Vice President of Technology, GKN
Aerospace, comments:  "This new development will have its
initial application in the global counter-terrorism market for
government VIP Armoured Personnel Vehicles but also has real
value in the civilian VIP market.  These 'SmartShade' windows
will give a level of control, protection and privacy for vehicle
occupants not available until now. "

The programme will address three distinct technical objectives.
The first will be to develop and refine a manufacturing process
which will enable SPD-SmartGlassTM technology to be
effectively incorporated into armoured windows. The second
will ensure these new windows perform effectively in a range of
extreme environmental conditions, and the third will be to
satisfy stringent ballistic testing performance requirements
against a variety of urban threats.

Dr Fischer continues: "We have exhibited our SPD-Smart bullet
resistant glazings at trade shows and directly to branches of the
military and government agencies, all of whom have expressed
strong interest in the potential benefits of smart window
technology.  We look forward to progressing and refining the
work that our team has already achieved with this CTTSO
contract."
