Finmeccanica's DRS Technologies has secured three contracts worth approximately $170m for programmes serving a range of US and Royal Australian Navy ships.
The latest contract covers work on network communications, missile launching, and combat display systems.
DRS Maritime and Combat Support Systems business president Roger Sexauer said: "These contracts represent the broad stem-to-stern, high-quality, and mission-critical capabilities that DRS brings to our US Navy and international customers.
"Our commitment to our customers is to provide the best experience and technology at the most affordable price."
Under a $15m US Navy indefinite-delivery, indefinite-quantity contract, DRS will be responsible for the delivery of digital combat display systems for surface ships.
Work under this deal includes hardware production, assembly, configuration, integration, testing, and shipping of the common display system (CDS) Technology Insertion 12.
DRS will supply network communications systems for the US Navy and Australian ships under a second contract.
The company will be responsible for the delivery of hardware, installation, and checkout repair.
It includes AN / USQ-82(V) gigabit ethernet data multiplex system (GEDMS), a high-speed network developed to meet expanding shipboard communications requirements, handling data critical to ship operation, maintainability, and survivability.
The third deal, which is a sub-contract with Lockheed Martin, will see the delivery of production hardware and various parts for the US Navy's MK41 vertical launching system (VLS).
DRS will provide launch control units and programmable power supply systems for the VLS, which is the missile launching system for the US Navy's guided missile cruisers and destroyers, allied navy surface combatants, and Aegis Ashore systems of the Missile Defense Agency's Ground-Based Missile Defense programme.
