Northrop Grumman to Supply Navigation Systems for Italian Navy Submarines

FREIBURG, Germany, June 1, 2010 - Northrop Grumman Corporation (NYSE: NOC) has been awarded a contract by
the Italian shipyard Fincantieri to deliver two full navigation suites for
the second pair of U212A class submarines being built for the Italian Navy.

This new contract represents the natural evolution of the joint
German-Italian Submarine Program. Fincantieri, which has already constructed
and delivered the first two submarines to the Italian Navy, is also building
the second pair of boats at its Muggiano shipyard.

The navigation suites, comprising the PL41 Mk4 ring laser gyro inertial
navigation system and the navigation data controller (NDC), will be supplied
by the company's German navigation systems subsidiary, Northrop Grumman
LITEF.

"Northrop Grumman LITEF has a long history of supplying naval navigation
products using both fibre-optic gyro and ring laser gyro technologies to
customers which include more than 30 of the world's navies and coast guards"
said Norbert Sandner, director of marketing and sales for Northrop Grumman
LITEF. "Our state-of-the-art PL41 Mk4 offers the high accuracy and
reliability these modern submarines need, and this award demonstrates
Northrop Grumman's continuing commitment to the international naval market."

The PL41 Mk4 is an advanced ring laser gyro inertial navigation system,
suitable for operating on board modern naval vessels. The equipment is
designed to provide continuous and automatic data outputs of ship's heading,
attitude and heave, corresponding rates, geographical position and velocity
information. The PL41 Mk4 consists of the basic unit (BU) and a remote
control and display unit (RCDU). The BU is an environmentally sealed cabinet,
which contains the motion sensitive inertial sensors, processing electronics,
input and output function, power and I/O distribution cable harnesses and
supporting electronics. The RCDU is provided for operator interface.

The navigation data controller (NDC) functions as a central navigation
computer and interface control, monitoring and distribution unit, and
features a proven dual redundant ring-bus architecture. A dedicated
intelligent interface reduces the master processor work load and increases
the data throughput substantially.

Northrop Grumman LITEF is a leading supplier of inertial sensors,
inertial reference and inertial navigation systems and computers with
products deployed in more than 30 countries in aircraft, naval and ground
mobile applications worldwide.
