Lockheed Martin's Integrated Combat System is the U.S. Navy's PEO IWS path toward a common, tailorable surface-fleet combat-system architecture. The program builds from Aegis and Ship Self-Defense System experience, separates combat-system software from shipboard compute infrastructure, and delivers ICS-enabled baselines on a faster certification cadence.
ICS is best documented as a software-led convergence program for U.S. Navy surface combat systems rather than as a separately fielded combat system with public conflict-use evidence under the ICS name.
Lockheed Martin was selected as the Integrated Combat System Systems Engineering and Software Integration agent for fleetwide surface-combatant modernization.

PEO IWS material describes a move from multiple segregated ship combat systems toward common requirements, common hardware and software, and a single integrated combat-system architecture.

The first delivered ICS-enabled baseline was identified as Aegis BL9.C3.0, combining heritage Aegis functions with Forge and Tactical PaaS infrastructure for containerized software.

Public ICS wording currently centers on architecture and software baselines rather than separate hardware variants.
| Variant | Configuration | Designation notes |
|---|---|---|
| Aegis BL9.C3.0 | First ICS-enabled baseline | Lockheed Martin identified the first delivered ICS-enabled baseline as Aegis BL9.C3.0, compiled from the Forge development environment and built on Tactical PaaS infrastructure. Sources: ICS baseline delivery release |
ICS-enabled baselines are documented as part of the Aegis modernization path rather than a separate combat stack.
