THOR, described as Tactical, High-Performance Embedded Computing, Open Architecture, Rugged, is a 3U VPX computing chassis built for combat vehicles and tactical platforms. It is designed to provide scalable processing power for data-intensive missions across multiple domains.
The system aligns with the Sensor Open Systems Architecture and the Department of Defense’s Modular Open Systems Approach. According to the company, this allows for rapid upgrades, reduced reliance on single vendors and improved long-term adaptability.
“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,” he added. The company said the system is part of its broader effort to enhance operational effectiveness in complex environments.
THOR is engineered to meet multiple military standards, including MIL-STD-810, MIL-STD-1275 and MIL-STD-461. It is designed to operate in extreme conditions involving temperature, shock, vibration and electromagnetic interference.
The system supports a range of computing payloads, including Intel-, Arm- and NVIDIA-based processors, as well as graphics processing units for artificial intelligence and machine learning tasks. It also accommodates radio frequency and digital signal processing modules for electronic warfare and secure communications.
With internal data rates of up to 100 gigabits per second, THOR is designed to provide high-throughput, low-latency performance. The system also incorporates cybersecurity capabilities to support networked operations.
Leonardo DRS said the system is optimized for platforms with constraints on size, weight and power. It can be delivered either as a configurable chassis kit or as a fully integrated subsystem combining computing, sensors, software and secure communications.
The company said this flexibility allows rapid prototyping and deployment of advanced capabilities. It also supports a transition from demonstration to full-rate production with reduced integration risk.
Beyond defense applications, THOR is suited for use in commercial and industrial sectors requiring high-reliability computing. These include robotics, machine vision, transportation monitoring and scientific field operations.
Leonardo DRS said the system strengthens its portfolio of advanced sensing and computing technologies. It is intended to improve situational awareness, accelerate decision-making and reduce the cognitive burden on operators in complex operational environments.
