Evolutionary Design



Ballistic Missile Defense

The Aegis Ballistic Missile Defense (BMD) system is the primary sea-based component of the U.S. missile defense system. Aegis BMD seamlessly integrates the SPY-1 radar, MK 41 Vertical Launching System, and SM-3 missile through an advanced command and control system.

Our systems provide layered missile defense capabilities as part of the U.S. Missile Defense Agency’s Ballistic Missile Defense System (BMDS) and the air and missile defense of allied nations.

In addition to Aegis BMD, Lockheed Martin systems that are part of BMDS include:

  • Long Range Discrimination Radar (LRDR)
  • Patriot Advanced Capability-3 (PAC-3)
  • PAC-3 Missile Segment Enhancement Missiles
  • Terminal High Altitude Area Defense system
  • Our Command, Control, Battle Management and Communications system seamlessly integrates and interconnects BMDS elements.

Integrated Air and Missile Defense

Aegis combines robust anti-air warfare (AAW) capabilities with an unprecedented ballistic missile defense (BMD 5.0) functionality into a single integrated air and missile defense (IAMD) system.

Common Source Library

The Aegis Common Source Library (CSL) enables customers to rapidly integrate new capabilities and processes across the fleet in a “build once, use many times” framework. Aegis CSL can be used across a variety of platforms, ranging from multiple classes and types of ships to land-based systems. Through the Aegis CSL, an innovation or new systems integration made for one Aegis vessel can be leveraged across the fleet and around the world.

Aegis CSL enhances life cycle affordability by reducing costs for integration, test and certification.

Common is key. This commonality allows far greater interoperability across the fleet, which will further reduce training costs and improve flexibility in crew assignments.

Littoral Combat Ships/Frigate

COMponent-BAsed Total-Ship System—21st Century (COMBATSS-21) is the combat management system in operation on the Freedom variant Littoral Combat Ship (LCS) and is the U.S. Navy’s choice as the combat management system for their next generation frigate program. 


The National Security Cutter’s Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) system ensures these ships are equipped to help the Coast Guard complete its most challenging missions.


By design, the Aegis Combat System has evolved in order to pace new and emerging threats.

The Aegis Modernization program effectively extends the life of in-service Aegis ships as they age. Two modernization programs – for both cruisers and destroyers – are currently in place that will improve warfighting capabilities, extend hull service life, and reduce total ownership cost through the fielding of Open Architecture and commercial computing technologies.



Building the world’s most advanced combat system is only the first step.

Lockheed Martin’s Aegis Ship Integration & Test (SI&T) team delivers both planned upgrades and engineered innovations to make ships more capable and survivable. In tandem with SI&T, Lockheed Martin also provides engineering services including design, development, integration, test and life cycle support for all Aegis-equipped ships through the Combat System Engineering Agent (CSEA) contract, which was re-awarded to Lockheed Martin in 2013.

The World Keeps Changing. We Design Systems that Change With It.

As technology grows and adversaries become more sophisticated, naval dominance, missile defense and nuclear deterrence must evolve to meet these new threats.
