Homeland Security

Lockheed Martin homeland security and homeland defense capabilities and solutions continue to grow to meet ever changing security threats in the 21st century. We are helping to secure our nation’s vital assets including transportation systems, food and water supply, and critical services such as health care, law enforcement, and emergency services.

Lockheed Martin has the flexibility, strength, and diversity to bring transformational technology, ideas, and processes to homeland security and homeland defense. We are a horizontally integrated company that focuses strategies, marshals competencies, integrates solutions, directs resources, streamlines processes and infuses technology to meet the needs of this dynamic environment.

Lockheed Martin has successfully addressed enterprise IT challenges within our own business that are very similar to those faced by DHS today. We developed the enterprise architectures and, drawing from the depth and breadth of our corporate expertise, successfully integrated its legacy IT infrastructure into one system.

We are leading major modernization and integration programs with key homeland security customers, such as the U.S. Coast Guard, Transportation Security Administration, Customs and Border Protection Agency, Federal Aviation Administration, and state and local governments.
We have provided the technology that guards borders, integrates threat information, protects critical infrastructures, and provides maritime surveillance. We are also safeguarding electronic systems that are susceptible to viruses, hacking, and identity and information theft.

Whether it’s providing satellite imagery to track threats or developing systems to analyze complex security data or deploying fingerprint ID technology for rapid first response, Lockheed Martin offers the depth of expertise and technological capabilities to help protect our homeland.
