Key International Northrop Grumman F-35 Supplier Delivers First Large, Complex Composite Structure

Turkish Aerospace Industries continues to expand, refine F-35 manufacturing skills

EL SEGUNDO, California, August 10, 2010 - Turkish Aerospace Industries, Inc. (TAI), a major international F-35
Lightning II supplier to Northrop Grumman Corporation (NYSE: NOC), has
delivered a prototype of its first major structural element for the jet's
center fuselage, which Northrop Grumman produces for F-35 industry team
leader Lockheed Martin (NYSE: LMT).

Known as a destructive test article, the prototype all-composite air
inlet duct reflects the growing maturity of TAI's composite fiber-placed
manufacturing processes, and the steady evolution of its role as a second
source supplier of center fuselages for the F-35 Joint Strike Fighter (JSF)
program.

TAI produced the air inlet duct at its composites manufacturing facility
in Ankara, Turkey as part of a five-year, US$28.4 million contract awarded to
the company in Sept. 2009 by Northrop Grumman.

"TAI has progressed steadily in learning the high-precision manufacturing
processes required to produce parts for the most capable multi-role fighter
in the world," said Mark Tucker, vice president and F-35 program manager for
Northrop Grumman's Aerospace Systems sector. "Its continued success helps us
ensure a smooth transition from our current rate of completing approximately
two center fuselages per month to an eventual rate of one center fuselage per
day."

According to Tucker, the destructive test article will be used to
validate the quality of TAI's composite manufacturing processes. Deliveries
of production quality inlet ducts are expected by the end of this calendar
year.

"This delivery is another major step by TAI to demonstrate its commitment
to the success of the F-35 Joint Strike Fighter program," said Muharrem
Dortkasli, TAI's president and chief executive officer.

According to Dortkasli, the company has made significant investment since
2007 in new technologies and facilities required to meet F-35 program
requirements. In addition to opening its Advanced Composites Facilities in
2008 and 2010, TAI plans to open a new F-35 JSF Center Fuselage Assembly and
Coating Facility in 2011.

The delivery of TAI's first air inlet duct follows a series of successful
composites manufacturing training sessions conducted over the last two years
for the company's engineers and manufacturing specialists by Northrop
Grumman. Held at Northrop Grumman's Advanced Composites Center in El Segundo,
the training included rigorous classroom and hands-on work to teach the TAI
employees how to fabricate an F-35 inlet duct from start to finish.

TAI is a second source supplier of F-35 air inlet ducts and center
fuselages to Northrop Grumman. The Turkish company is slated to produce inlet
ducts to support both the current production of center fuselages on Northrop
Grumman's F-35 assembly line in Palmdale, Calif., and the 400 complete center
fuselages that it will produce in Turkey.

Deliveries of the TAI-produced center fuselages are scheduled to begin in
2013, as part the F-35 program's sixth phase of low rate initial production.

Since 2008, TAI has been producing increasingly complex components and
subassemblies for Northrop Grumman-assembled center fuselages. The company
delivered its first F-35 components to Northrop Grumman in late 2008, and its
first structural assemblies for the jet in March 2009.

TAI's modern facilities in Ankara are furnished with high technology
machinery and manufacturing equipment that provide capabilities ranging from
parts manufacturing to complete aircraft and helicopter manufacturing,
assembly and flight tests. TAI also designs, develops and integrates
aerospace systems and provides modernization and after-sales support
services.

Northrop Grumman is responsible for designing and producing the center
fuselage for all three variants of the F-35. The company also designed and
produces the aircraft's radar and other key avionics including
electro-optical and communications subsystems; develops mission systems and
mission-planning software; leads the team's development of pilot and
maintenance training system courseware; and manages the team's use, support
and maintenance of low-observable technologies.

Northrop Grumman Corporation is a leading global security company whose
120,000 employees provide innovative systems, products, and solutions in
aerospace, electronics, information systems, shipbuilding and technical
services to government and commercial customers worldwide. Please visit
