Raytheon Company's expertise in Ship System Integration (SSI) requires the capabilities to manage the Total Ship Systems Engineering Process to translate total ship top level system performance requirements (as defined in ORDs) through requirements analysis, Trade-off Studies, and their decomposition into functional baselines to synthesis into Concept Design Baselines.

Furthermore Raytheon's SSI expertise involves Management of the Ship's Information Systems Engineering and Integration to design the Ship's Information Architecture and Infrastructure, Control Systems, Vessel Management Systems, Combat and C4ISR Systems, and enabling High Level Simulation and Mission/Operations Analysis.

Critical to these capabilities is the effective use of a variety of System Engineering and Total Ownership Cost Processes, Procedures, and Tools including IMS/IMP, WBS, SEMP, IPPD/IPTs, Model and Simulation, CAIV Analysis, and COTS Integration and Technology refresh. Raytheon has successfully performed Ship System Integration in a number of U.S. and Foreign Navy Ship Acquisition Programs including LPD-17, DD 21, T-AGOS SURTASS, CVX, and TLF, as well as a large number of Ship and Submarine Combat Systems (SSDS Mk 1/2, ACDS, CEC, BSY-I/II, and NSSN C3I).

LPD-17 Systems Integration
The Navy's newest class of ship, the San Antonio (LPD-17), will be a highly reliable, warfare capable ship and the most survivable amphibious ship ever put to sea. The design incorporates state-of-the-art self-defense capabilities, C4I, and reduced signature technologies. Reduced operational costs and adaptability to technological advances over its 40-year service life are key design objectives. LPD-17 also incorporates the latest quality of life standards for the embarked Marines and Sailors with the flexibility to accommodate women Marines and Sailors as part of the crew and embarked troops.

DD-21 Systems Integration
As a "revolutionary, vice evolutionary, platform", the DD 21 manifests a significant technological revolution in ship design. Its primary mission will be land attack in support of ground forces, providing 5-inch/62 caliber Extended Range Guided Munitions and 155-mm howitzer surface fires to ranges of 100 nautical miles. Also, the DD 21 will carry a supersonic land attack missile and the tactical Tomahawk, possessing a firing range of more than 1,500 nautical miles. The DD 21 will contribute to battlespace dominance with "the most advanced under-sea warfare combat systems suite ever installed in a surface combatant". By employing helicopters and unmanned aerial vehicles, cross-layer multistatic sonar, torpedo countermeasures, submarine-like sound quieting and organic minehunting, DD 21 will be singularly outfitted to the many challenges and threats posed in 21st-Century warfare.

CVN Warfare Systems Integration
The next generation carrier will be a more modern, affordable aircraft carrier that will be a multi-mission, multi-threat tactical aviation sea-based platform. Besides reducing total cost and supporting affordability, the key objective for the CVN program is to capitalize on automation insertion and innovative technology in a clean sheet design to improve core carrier capabilities including ship survivability, joint C4I, and conops for current and future aircraft such as F/A-18E/F, JSF and the follow-on to JSF.
