First of up to 25 launches of Low Earth Orbit technology demonstration satellites to be built and operated by Lockheed Martin. TacSat is an intelligence, surveillance and reconnaissance spacecraft with a mission to prove specialized sensing and communications capabilities on orbit. The satellite will participate in exercises that highlight cross-domain kill-web connectivity, enabling timely execution of tactical space missions. TacSat will host a proven Lockheed Martin infrared sensor on board that brings previously developed technology to space for the first time. This sensor produces high quality imagery and it can interface with federated Battle Management Command & Control (BMC2) combat systems to provide joint forces with a comprehensive view of threats. The satellite will also feature Lockheed Martin’s first 5G.MIL® payload on orbit. This provides cellular-like networking for military space assets, making satellite constellations more resilient. It also helps enable seamless connectivity with tools in the air, at sea and on land. Launch operation will also again demonstrate responsive space pre-launch operation capabilities.
