Case Study: U.S. Navy – Aegis Weapon System Modernization

Concurrent Real-Time’s RedHawk Linux and NightStar tools enabled Lockheed Martin and the U.S. Navy to transition the Aegis Weapon System to a modern, open architecture—improving determinism, integration speed, and lifecycle cost efficiency.

The Aegis Weapon System has long served as the backbone of the U.S. Navy’s air and missile defense operations, coordinating real-time responses across anti-air, anti-surface, and anti-submarine missions. As part of the Cruiser Modernization initiative, Lockheed Martin shifted Aegis from a closed, proprietary environment to an open, modular architecture. To meet the Navy’s mission-critical timing requirements, they selected Concurrent Real-Time’s RedHawk Linux and the NightStar analysis suite.

RedHawk Linux delivers predictable, microsecond-level response times needed to detect, track, and respond to multi-domain threats. NightStar provides real-time visibility into system behavior, enabling precise debugging, event tracing, and performance tuning without disrupting deterministic execution. Together, these tools form the technical foundation for a more flexible, cost-effective Aegis architecture capable of faster capability deployment and simplified technology refresh cycles.
