We build mobile, ground-based systems that detect, track and defeat aerial threats before they reach forces and critical assets. AirShield, IFPC and Mjolnir offer complementary capabilities that give commanders greater flexibility to respond as mission conditions change.
Defense
Connecting platforms, sensing, command, and effects
Ready when the mission calls. Proven where it matters.
The threat doesn't wait. Neither does our defense tech.
Leidos turns advanced ideas into fielded capability for U.S. forces and allied partners in the United Kingdom and Australia – proving what works then rapidly scaling for the mission.
We bring hardware, software and deep operational expertise together across munitions and missiles, sensors and effectors, and maritime autonomy. Paired with digital modernization, these capabilities connect systems and keep data flowing securely to the tactical edge — giving forces the information they need to decide and act faster.
Proof that speed and scale can work together
C-UAS built to move
AirShield integrates sensing, automated decision-making and layered effectors in an open, mobile system designed to accelerate the response from detection to defeat.
IFPC Inc 2 Production
Indirect Fires Protection Capability Increment 2 (IFPC Inc 2) launchers are in mass production for the U.S. Army's integrated layered air and missile defense capabilities.
90 days from concept to contract
Low-Cost Containerized Munitions (LCCM) moved from concept to a government-committed framework agreement for 3,000 units in under 90 days.
Multi-domain advantage from day one
Fast matters. Getting it right across land, air, sea, space, and cyber domains matters more. We integrate sensing, command, data, and effects into mission systems designed to perform in operational environments and scale without rework.
Air
We support air-domain missions with precision strike systems, hypersonics, small cruise missiles, glide munitions, ISR, and intelligence support. The AGM-190A Havoc Spear small cruise missile was developed and flight-tested in about half the time of prior missile programs, while the Common Hypersonic Glide Body is in production for long-range hypersonic weapon programs.
Sea
We support maritime missions with unmanned systems, advanced sensing, fires integration, and assured network infrastructure. The Leidos Autonomous Vessel Architecture (LAVA) has been validated across multiple platforms, helping the Navy advance autonomy, modular integration, and mission flexibility for the hybrid fleet.
Space
We develop space sensing capabilities, including electro-optical/infrared payloads, that support space domain awareness, missile warning, tracking, and missile defense missions. Leidos-built infrared sensing payloads are part of satellites Sierra Space is building for the Space Development Agency’s Accelerated Missile Defense Tranche 3 program.
Cyber
We help defense customers turn cyber insight into operational advantage across contested environments. Combining threat intelligence, AI-enabled analysis, and real-world operator experience, we accelerate how teams anticipate threats, make decisions, and act—while strengthening resilience to keep critical operations moving.
See the mission clearly
You can't act on what you can't see. Our sensor technologies detect, track and characterize threats across land, sea and space — turning data from the environment into intelligence operators can act on.
ALPS
Army Long Range Persistent Surveillance (ALPS) provides continuous, passive situational awareness without emitting signals that reveal its position. With long-range, 360-degree coverage, rapid deployment and networked integration, ALPS helps operators detect and track activity while remaining undetected.
LAVS
The Leidos Acoustic Vector Sensor (LAVS) is a compact, 3D directional sensing system that helps operators locate and understand activity beneath the surface. It supports ocean surveillance, marine mammal monitoring and maritime situational awareness.
EO/IR
Designing and fielding electro-optical and infrared sensing payloads for high-fidelity missile warning and tracking and space domain awareness — helping operators detect, track and understand threats from orbit.
Solutions for the Digital Battlefield
With AI, cyber, and mission software at our core, we're helping warfighters move faster than the threats they face.
