Northrop Grumman Submits Proposal for NATO Alliance Ground Surveillance

Transatlantic cooperation is NATO's top acquisition program of record

MELBOURNE, Florida, June 8, 2010 - Northrop Grumman Corporation (NYSE: NOC) formally submitted its proposal
this week for the NATO Alliance Ground Surveillance (AGS) system - NATO's top
and long-running acquisition program. A contract award is anticipated in
October 2010.

"This program has been a model of the value of transatlantic cooperation
to meet the security challenges of the 21st century, and we are proud to lead
an industry team of more than 25 companies from the 15 nations participating
in this program," said Pat McMahon, sector vice president of Northrop Grumman
Aerospace Systems' Battle Management & Engagement Systems business unit. "The
true value of this multinational effort shows in this proposal. This industry
team brings together leading defense industries and their state-of-the-art
air and ground capabilities to take advantage of national investments already
made in operationally fielded and proven systems for the good of the entire
alliance. The result is an affordable, executable program that will provide
the earliest fielded capability to meet the alliance's urgent need to protect
its forces with persistent intelligence, surveillance and reconnaissance."

The NATO AGS proposal includes an air segment based on the Block 40
version of the RQ-4 Global Hawk high-altitude, long-endurance (HALE) unmanned
aircraft that will be missionized to meet NATO requirements. It also includes
mobile and transportable ground stations and a world-class mission operation
support center at the main operating base in Sigonella, Italy.

The NATO air vehicle will be equipped with Northrop Grumman's
Multi-Platform Radar Technology Insertion Program (MP-RTIP) ground
surveillance radar sensor, which will be capable of detecting and tracking
moving objects throughout the observed areas as well as providing radar
imagery of target locations and stationary objects. The entire system will
empower a network-enabled approach to support interoperability with national
systems and to perform the entire range of NATO missions, from peacetime to
crisis management.

The ground element will be wholly produced by European industry, offering
the potential for national re-use in other programs. It provides real-time
data, intelligence and target identification to ground commanders within and
beyond line of sight.

"As a critical component of the NATO Response Force, the AGS system will
give NATO and national decision-makers continuous ground situational
awareness to enable a tailored response to meet the situation and minimize
the need to put forces in harm's way without foreknowledge. It will be
crucial for success in Afghanistan and in future out-of-area operations,"
said Matt Copija, director of Northrop Grumman's NATO AGS program.

The system leverages the Global Hawk's combat-proven performance and
unmatched capabilities, with more than 40,000 hours flown at altitudes up to
60,000 feet for more than 32 hours, well above commercial airspace. The NATO
AGS program will mark the first international sale of the Block 40 version of
the Global Hawk.

Northrop Grumman is the prime contractor for the NATO AGS program based
at its Melbourne, Fla., facility. Its industrial team includes EADS, Selex
Galileo, General Dynamics Canada, and Kongsberg. The NATO Alliance Ground
Surveillance Management Agency (NAGSMA), which was chartered to acquire the
NATO-owned and operated core capability, is responsible for the procurement
of the NATO AGS capability until it has reached full operational capability.
NAGSMA was established in September 2009 after all 15 participating nations
signed the AGS program memorandum of understanding.
