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 across the fleet in a “build once, use many times” framework. Aegis CSL can be used across a variety of ship classes and land-based systems to perform a wide range of missions. Lockheed Martin applies its unique combat system expertise to deliver a combat system capability that supports the diverse missions of the Surface Navy while applying  a common, open architecture across the entire fleet and around the world.

Today, the CSL is used on Aegis Cruisers and Destroyers, Littoral Combat Ships, Coast Guard National Security Cutters and Offshore Patrol Vessels, Aegis Ashore and is planned for Frigate, Canadian Surface Combatant, and the Saudi Multi-Mission Surface Combatant. Aegis allies have grown to include Japan, Canada, Norway, Korea, Spain, and Australia. These international partners are currently building ships that will draw from the CSL to support their mission on Frigates and Destroyers.                                                                                                                                       

Aegis CSL enhances life cycle affordability by reducing costs for development,  integration, and test through extensive commonality and reuse.  The CSL is moving toward more rapid fielding of capability and enabling early collection of data required for training, tactics development and certification.
CSL has established the commonality essential to an integrated combat system and is facilitating greater interoperability across the fleet, reduced training costs and improved flexibility in crew assignments.

The CSL is designed to deliver total combat system performance through its evolved architecture.  It delivers capability TODAY and is flexible to grow with the demands of an ever-changing environment.

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.


As the warfighter’s needs change, Lockheed Martin continuously evolves to quickly provide innovative and affordable capabilities to the fleet. Lockheed Martin has over 42 years of ship integration and test experience across 12 ship classes, including combat system elements for every Aegis Cruiser and Destroyer, Freedom variant Littoral Combat Ship, six international ship classes, Aegis Ashore and the Coast Guard.”

While minimizing ship impact and cost, the Lockheed Martin Ship Integration & Test (SI&T) team deliver both planned upgrades and engineered innovations to make ships more capable and survivable. This valuable team also provides engineering services including design, development, integration, test and life cycle support for ships as the Navy’s current Combat System Engineering Agent (CSEA).
