Northrop Grumman Corporation (NYSE: NOC) has been selected to retrofit new-generation navigation radars on more than 100 German Navy warships.

Northrop Grumman’s U.K.-based Sperry Marine business unit was awarded a $4.3 million contract from ET Marine Systeme GmbH, Wilhelmshaven, Germany, prime contractor for the navigation-systems modernization program.

Under the four-year contract, the ships’ existing navigation radars will be replaced by Sperry Marine’s BridgeMaster E 340 radar systems, including commercial, navalized and tactical variants, in X-band, S-band and dual-band configurations. The contract includes training, spares, installation, engineering and project-management support. ET Marine Systeme will integrate the radars with the ships’ electronic chart display and information systems and automatic identification systems.

The first installations are scheduled to take place in the first quarter of 2006. In the meantime, Sperry Marine is supplying BridgeMaster E systems for the German Navy training school and test sets.

Sperry Marine has also supplied BridgeMaster E radars to a large number of European navies, including France, the United Kingdom, Sweden, Greece, Norway and Poland.

Headquartered in Charlottesville, Va., Sperry Marine provides smart navigation and ship control solutions for the international marine industry with customer service and support through offices in 16 countries, sales representatives in 47 countries, and authorized service depots in more than 250 locations worldwide.

Sperry Marine is part of Northrop Grumman’s Baltimore, Md.-based Electronic Systems sector, a world leader in the design, development and manufacture of defense and commercial electronic systems including airborne radar, navigation systems, electronic countermeasures, precision weapons, airspace management systems, communications systems, space sensors, marine and naval systems, government systems and logistics services.
