Lockheed Martin was awarded a $35m contract to deliver advanced, open-architecture combat systems that will modernize four Tupi-class submarines, one Tikuna-class submarine and one shore-based trainer system for the Brazilian Navy. Under a contract administered by the U.S. Navy, as part of a foreign military sale for weapons and combat systems to the Brazilian Navy, Lockheed Martin will provide systems engineering, sensors, software and electronics for the modernization of the diesel submarines’ control, combat management, sonar and fire control and weapons launch systems. The modernized systems will provide the Brazilian Navy tangible improvements in overall submarine performance with dramatically improved war fighting capability.
