Leidos
Leidos is a Reston, Virginia-based technology contractor working across defence, intelligence, civil and health markets. Listed on the NYSE as LDOS, it provides systems integration, software, cyber, sensors and logistics. In defence, its work includes air and missile defence, maritime autonomy, mission software and command-and-control infrastructure. The company is primarily a contractor and integrator rather than a dedicated drone manufacturer.
Key Products
- Indirect Fire Protection Capability Increment 2 - a U.S. Army air-defence programme intended to counter drones, cruise missiles, rockets and artillery threats.
- Autonomous maritime systems - Leidos has supported U.S. Navy and defence experimentation involving long-endurance autonomous vessels.
- Airborne and ground ISR systems - sensor integration, mission software, and data processing tools used across defense and intelligence missions.
- Cyber and command-and-control platforms - software and systems integration supporting military networks, decision support, and operational coordination.
Business and Funding
Leidos is publicly traded on the NYSE under LDOS. For the second quarter of fiscal 2026, it reported revenue of $4.6 billion, net income of $356 million and operating cash flow of $793 million. It reported $5.0 billion of awards in the quarter. Adjusted EBITDA of $631 million and free cash flow of $761 million were non-GAAP measures reported by the company. These are consolidated figures, not revenue attributable solely to counter-UAS or autonomous programmes.
Why It Matters
Leidos matters because modern air defence and autonomy depend on integration: launchers, sensors, communications, software and sustainment must work together. Its role is usually less visible than the platform maker’s, but it can be central to deploying a system at scale. Readers should not treat a large company-wide award total as a dedicated drone figure. The more useful signal is whether specific programmes move from prototype or support work into sustained, funded fielding.
