Press Release, Arlington VA, 24 March 2026: Leonardo DRS, Inc. announced today the introduction of THOR (Tactical, High-Performance Embedded Computing, Open Architecture, Rugged) – a rugged, open-architecture 3U VPX embedded computing chassis purpose-built to deliver high-performance processing at the tactical edge. Designed for combat vehicles, tactical platforms, and emerging mission environments, THOR provides the scalable computing backbone warfighters need to run artificial intelligence, fuse multi-sensor data, and make faster, more informed decisions under fire.
As the US military accelerates its modernisation agenda across ground, air, and emerging domains, the demand for deployable, high-density computing at the point of need has never been greater. THOR directly addresses this requirement. Aligned with the Sensor Open Systems Architecture (SOSA) and the Department of War’s Modular Open Systems Approach, THOR enables rapid technology insertion, reduces vendor lock-in, and provides a clear upgrade path – ensuring combat systems remain effective against evolving threats without costly platform redesigns.
“Today’s battlefield demands computing solutions that are as agile and resilient as the forces they support,” said Denny Crumley, senior vice president and general manager of the Land Electronics business unit at Leonardo DRS. “THOR was designed from the ground up to meet that challenge. It brings together open-architecture flexibility, military-grade ruggedness, and the processing power required for AI-enabled operations – all in a form factor that deploys where it matters most. THOR represents a significant step forward in our Advanced Sensing and Computing portfolio, and it reflects our commitment to delivering technology that gives warfighters a decisive advantage.”
Engineered to MIL-STD-810, MIL-STD-1275, MIL-STD-461, and ATPD-2404 standards, THOR operates reliably in extreme temperature, shock, vibration, and electromagnetic environments where commercial computing solutions fail. The chassis supports a broad range of compute payloads – including Intel, Arm, and NVIDIA-based single board computers, high-performance GPUs for AI and machine learning inference, and RF and digital signal processing modules for electronic warfare and secure communications. With internal data rates up to 100 Gbps and support for cyber security capabilities, THOR delivers the low-latency, high-throughput performance that advanced sensing and network-centric operations demand.
THOR is optimised for size, weight, and power-constrained platforms and is available as a configurable chassis kit or as a fully integrated Leonardo DRS subsystem – combining the company’s computing, sensor, software, and secure communications technologies into a mission-ready package. This flexibility enables system integrators and program offices to rapidly prototype, evaluate, and field advanced capabilities with reduced integration risk and a clear path from demonstration to full-rate production.
Beyond defence, THOR’s compute density, ruggedness, and standards-based architecture make it well-suited for demanding commercial and industrial applications – including advanced robotics, machine vision, railway and transportation monitoring, and field-deployable scientific instrumentation – where deterministic, high-reliability performance is essential.
The introduction of THOR reinforces Leonardo DRS’s position as a trusted provider of next-generation advanced sensing and computing technologies that improve situational awareness, accelerate decision-making, and reduce the cognitive burden on commanders and crews operating in complex, multi-domain environments.
THOR will be showcased at the AUSA Global Force Annual Meeting & Exposition in Huntsville, Alabama.
