Connecting platforms, sensing, command, and effects
Where warfighter advantage gets real
When the stakes are high, results matter. Leidos brings together hardware, software, and operational expertise to deliver mission-ready capability - fielded and in use. From homeland defense to multi-domain operations we help U.S. forces and allied partners in the United Kingdom and Australia turn complexity into real operational advantage.
From Concept to Impact - Faster

Domains
Multi-domain advantage from day one
Fast matters. Getting it right across domains matters more. Leidos delivers end-to-end, multi-domain mission solutions - connecting sensing, command, and effects into fielded capability that performs from day one and scales without rework.
Land
Mobile, ground-based systems to protect critical assets from threats ranging from cruise missiles, drone swarms, single aircraft, and other manned/unmanned aerial threats. Continuous, undetectable situational awareness also provided with a passive, long-range sensor.
Air
Delivering precision strike capabilities spanning hypersonics, AGM-190A small cruise missile, small glide missiles, and Tomahawk support. We also enable ISR and intelligence-driven operations that accelerate decision advantage for the warfighter, while sustaining aircraft readiness through F-16 mission capability support for foreign military sales.
Sea
Delivering integrated maritime operations at speed and scale with unmanned systems, advanced sensing, fires integration, and assured network infrastructure.
Space
Space sensing, including electro-optical / infrared (EO/IR), provides space domain awareness, space control, and early detection, tracking, and interception capabilities to neutralize missile threats from anywhere on the globe.
Sensors
See the mission clearly
Our sensor technologies give operators a clear, real-time picture of the environment and emerging threats. From the ultimate high ground to the depths of the sea, we we turn data into clear, actionable insight.
ALPS
Army Long Range Persistent Surveillance (ALPS) is a passive, long-range sensor providing continuous situational awareness without emitting signals that reveal its position. With 360° coverage and high reliability, ALPS strengthens homeland and battlefield defense through rapid deployment and networked integration.
LAVS
Leidos Acoustic Vector Sensor (LAVS) is a compact, 3D directional sensing solution for ocean surveillance, marine mammal monitoring and situational awareness.
EO/IR
Design and fielding of electro-optical and infrared (EO/IR) sensing payloads for high-fidelity missile warning & missile tracking and space domain awareness.
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.
