L3Harris Technologies received a $150 million contract from the U.S. Space Force's Space Systems Command on April 7, 2026 to sustain and modernize critical ground systems under MOSSAIC — Maintenance of Space Situational Awareness Integrated Capabilities. Per L3Harris' own press release.
What MOSSAIC funds
L3Harris provides sustainment and modernization of GEODSS (Ground-Based Electro-Optical Deep Space Surveillance) systems under MOSSAIC. The program is now in its seventh year of a decade-long effort delivering reliable, high-availability surveillance data to military, civil, and commercial stakeholders.
Why this is interesting
- Ground-segment is where most SSA value gets created — antennas, signal processing, fusion engines
- Civil/commercial integration scope means commercial-space data buys may flow through L3Harris' MOSSAIC pipe
- 10-year commitment from 2019 means a 2029 follow-on competition is on the horizon
What to do
- Antenna and RF firms: L3Harris is the SSA ground-systems prime — engage on subs
- Catalog/cataloging-software vendors: Andromeda + MOSSAIC together are the SDA backbone
