Summary
Lockheed Martin is self-funding two new space dominance initiatives aimed at enhancing orbital warfare capabilities for the U.S. Defense Department. The initiatives, named Vanguard and Sentinel, focus on rendezvous and proximity operations (RPO) and command and control. Tim Lynch, vice president for Mission Strategy at Lockheed Martin, announced these plans during a media briefing at the Space Symposium in Colorado Springs on April 14, 2026. The Vanguard system is designed as a smaller, lower-cost platform, while Sentinel will be a medium-class system with enhanced capabilities. Demonstrations for these systems are targeted for late 2028 and early 2029. Lockheed Martin aims to create plug-and-play subsystems to adapt to various customer needs. The company has already secured early adopters to provide input on the systems. Additionally, Lockheed Martin was awarded a $1.8 billion contract for the Space Force's Geosynchronous Reconnaissance & Surveillance Constellation program, which will also involve RPO missions. Key Points: • Lockheed Martin is developing two new satellite systems, Vanguard and Sentinel, for orbital warfare. • Demonstrations of these systems are planned for late 2028 and early 2029. • The Vanguard system will be a smaller, cost-effective platform, while Sentinel will offer advanced capabilities.
