Lockheed Martin To Provide Surveillance Radar to United Kingdom for World's Largest Offshore Wind Farm

LONDON, April 13, 2010 - Lockheed Martin (NYSE: LMT) will deliver a long-range air surveillance
radar system to the United Kingdom that overcomes sensor performance issues
commonly caused by the rotating blades of wind turbines.

The advanced electronics of Lockheed Martin's TPS-77 radar mitigate
interference, or "clutter," that commonly obscure radar targets in and around
wind farms. The new radar system will provide reliable air defense
surveillance capabilities for the U.K. Ministry of Defense (MoD) and allow
the nation to move forward with aggressive plans to install some 924 turbines
along England's east coast.

The radar will provide surveillance over five planned wind farms in the
Greater Wash Strategic Area — Sheringham Shoal, Race Bank, Dudgeon, Triton
Knoll and Docking Shoal — that are expected to generate more than 5,500
megawatts of sustainable power.

Under contract with Serco, Lockheed Martin will deliver this new TPS-77
system by November 2011. In the U.K., Serco has served as Lockheed Martin's
in-country Contractor Logistic Support partner for the MoD's FPS-117, or Type
92 radars, delivering greater than 98 percent operational availability.

The TPS-77 radars' capabilities in "green" wind field environments has
been demonstrated in tests at land-based wind farms near the company's
outdoor test range in Cazenovia, NY, as well as in trials with the Horns Rev
offshore wind farm in the North Sea. The radar itself is also highly
energy-efficient, delivering top performance while using just half the power
of comparable S-band radars.

The new TPS-77 radar system supports the goals of the U.K. Department of
Energy and Climate Change to reduce fuel consumption. In 2009, the U.K.
established the Low Carbon Transition Plan to reduce emissions 34 percent
from 1990 levels by 2020. The plan calls for an 80 percent reduction by 2050.
With more than 200 operational offshore wind farms, wind power is the
nation's biggest renewable energy source. In 2008, the U.K. surpassed Denmark
as the largest offshore wind generator in the world.

"Lockheed Martin continually incorporates state of the art technology
into its TPS-77 and FPS-117 family of ground-based radars," explained Carl
Bannar, vice president and general manager of Lockheed Martin's Radar Systems
business. "This investment allows us to provide new capabilities and enhanced
performance for customers while leveraging the field proven architecture and
30 years of operational experience with our family of long range radars."

Lockheed Martin's TPS-77 is the latest configuration of the world's most
successful 3-D solid-state radar design. This fixed site or transportable
radar provides continuous high-quality 3-D surveillance on aircraft targets
at ranges out to more than 250 nautical miles.

Lockheed Martin's TPS-77 shares a high degree of logistics commonality
with the FPS-117 (Type 92) radar. Today, 33 TPS-77s and 134 FPS-117 systems
are operational in 25 countries. Many have performed for years completely
unmanned in remote areas, and in a wide range of operational environments.

Headquartered in Bethesda, Md., Lockheed Martin is a global security
company that employs about 140,000 people worldwide and is principally
engaged in the research, design, development, manufacture, integration and
sustainment of advanced technology systems, products and services. The
Corporation reported 2009 sales of US$45.2 billion.
