L3Harris Technologies
U.S. defense and aerospace contractor spanning space, ISR, communications, and missile systems
Overview
L3Harris Technologies is a U.S. defense and aerospace contractor formed in 2019 through the merger of L3 Technologies and Harris Corporation, both of which trace their origins back over a century. Headquartered in Melbourne, Florida, the company is one of the largest suppliers to the U.S. Department of Defense, NATO allies, and intelligence agencies, with revenue consistently ranking it among the top five U.S. defense primes.
The company's portfolio spans space-based sensing and missile-tracking satellites, tactical and strategic communications systems, intelligence, surveillance and reconnaissance (ISR) payloads, electronic warfare, avionics, and — following its 2023 acquisition of Aerojet Rocketdyne — solid and liquid rocket propulsion for both government and commercial launch customers.
L3Harris matters to the industry because it sits at the intersection of legacy defense manufacturing and the newer, faster-moving space and missile-defense markets, including the Pentagon's Golden Dome missile-defense architecture and resilient missile-warning satellite constellations for the Space Development Agency and Space Force. Its scale and vertical integration — from propulsion to sensors to communications — allow it to bid on large, multi-domain programs that smaller space startups cannot address alone.
In 2025-2026 the company undertook a strategic reshaping of its space business, including a planned divestiture of a majority stake in its Space Propulsion and Power Systems unit while retaining exposure to missile tracking, munitions, and hybrid satellite communications, areas it has flagged as priority growth drivers under its 'LHX NeXt' cost and portfolio optimization program.
Products & Vehicles
Space & Mission Systems (Satellites and Payloads)
Missile-warning and missile-tracking satellites, electro-optical/infrared sensors, and reconnaissance payloads for the U.S. Space Force and Space Development Agency, including demonstrated hypersonic missile tracking from orbit. Specific payload mass and orbit specs vary by program and are not publicly standardized.
Aerojet Rocketdyne Propulsion
Solid and liquid rocket propulsion systems, including RL10 and RS-25 engine families, used on launch vehicles such as United Launch Alliance's Vulcan Centaur and NASA's Space Launch System. First flight of legacy RS-25: 1981 (Space Shuttle). Acquired by L3Harris in July 2023.
Tactical and Satellite Communications
Handheld and vehicular tactical radios, hybrid satcom terminals enabling military aircraft to access commercial broadband constellations (demonstrated with Starlink-class services in 2025), and secure executive aircraft satcom systems under U.S. Space Force contracts.
Missile Systems and Munitions
Production of precision munitions and missile components, an area receiving significant Pentagon investment (including a reported $1 billion commitment announced around January 2026) to expand manufacturing capacity.
ISR and Sensing Systems
Airborne and space-based intelligence, surveillance and reconnaissance sensors, electronic warfare systems, and weather satellite instruments, supported by a new automated manufacturing facility in Fort Wayne, Indiana (announced 2025).
Track Record
- 2019: L3Harris Technologies formed via all-stock merger of L3 Technologies and Harris Corporation, creating a top-tier U.S. defense contractor.
- July 2023: Completed acquisition of Aerojet Rocketdyne, adding solid and liquid rocket propulsion capability spanning NASA, Space Force, and commercial launch customers.
- 2025: Demonstrated missile-tracking satellite capability against hypersonic targets, strengthening its position in the Pentagon's Golden Dome missile-defense competition.
- September 2025: Successfully tested hybrid satcom radios enabling military aircraft to use commercial broadband (e.g., Starlink-class) services with government-grade encryption.
- January 2026: Announced agreement to sell a majority stake in its Space Propulsion and Power Systems unit to AE Industrial Partners for approximately $845 million, retaining a 40% stake; reaffirmed continued investment in core space and missile-tracking business amid reports of a $1 billion Pentagon investment in its missile unit.
- January 29, 2026: Reported full-year and Q4 2025 results, including a non-cash goodwill impairment tied to the Space Technology disposal group, alongside initiation of 2026 financial guidance.
- 2026: Realigned corporate structure from four reporting segments to three, including a renamed Space & Mission Systems segment, effective at the start of fiscal 2026.
- April 2026: Raised 2026 profit guidance following strong Q1 results driven by weapons and military intelligence system demand.
Roadmap
L3Harris has guided to continued growth in 2026, raising its full-year profit outlook after strong Q1 2026 results driven by munitions and intelligence systems demand. The company plans to close the sale of a majority stake in its Space Propulsion and Power Systems unit to AE Industrial Partners in the second half of 2026, while retaining a 40% interest. Management has signaled continued investment in missile-tracking satellites and sensors to compete for Golden Dome missile-defense work, and plans to scale production of hybrid satellite communications radios following successful Air Force testing. The company is also executing its three-segment organizational structure adopted at the start of 2026 and continuing cost-reduction efforts under its LHX NeXt program.
