Lockheed Martin has announced plans to launch its Tactical Satellite (TacSat) using Firefly Aerospace’s Alpha rocket in 2025. This launch marks the second mission under a multi-launch agreement between the two companies. Funded internally by Lockheed Martin, the mission will demonstrate advanced technologies for the defense sector.
TacSat, a small satellite roughly the size of a mini-fridge, utilizes a Terran Orbital Zuma bus—a platform also used by Lockheed Martin for the Space Development Agency’s military network. The satellite's key features include an infrared imaging sensor and a 5G communications payload. These components are designed to meet the Pentagon's demand for “all-domain networks,” which seamlessly connect space assets with ground, sea, and air forces.
The 5G payload, offering “cellular-like networking,” is expected to significantly improve the resilience of satellite constellations. It will facilitate real-time data sharing and enhance coordination during military operations. The infrared sensor, a previously developed technology, will be deployed in space for the first time, providing high-quality imagery for potential military applications.
This mission aligns with Lockheed Martin's broader strategy to support the Department of Defense's push for multi-domain operations. This concept emphasizes seamless communication across all military branches and their assets, including satellites, fighter jets, and naval vessels.
This TacSat launch represents the second collaboration between Lockheed Martin and Firefly. The first mission, already scheduled, involves Lockheed Martin’s LM400 medium satellite platform. Firefly’s Alpha rocket, capable of launching up to 1,000 kilograms to low Earth orbit, is gaining popularity in the small-satellite launch market.
On December 9th, Lockheed Martin announced that TacSat completed its final tests at the company’s Littleton, Colorado facility.
