Open Architecture and High-Performance Embedded Computing Solution, Built for Mission-Critical Environments
Modern platforms demand increasing compute performance without compromising survivability or adaptability. THOR meets that demand—at the edge, and beyond.
THOR is Leonardo DRS’ next-generation implementation of this architecture—a 3U VPX, SOSA™-aligned high-performance compute chassis engineered to bring OpenVPX® capability to the tactical edge. Purpose-built for size, weight, and power-constrained environments, THOR delivers scalable, open-architecture processing designed to support today’s operational missions and rapidly evolving future requirements alike.
OpenVPX® has emerged as the industry standard for modular, high-performance embedded computing across defense, aerospace, and rugged commercial markets. Engineered to deliver scalable processing, high-speed data movement, and interoperability in harsh environments, OpenVPX enables system developers to deploy advanced computing architectures wherever performance, reliability, and long lifecycle support are required.
From next-generation military platforms and avionics systems to industrial automation, transportation infrastructure, and scientific applications, OpenVPX® provides a common open framework that accelerates technology insertion while reducing integration risk and total lifecycle cost.
THOR Highlights
Open Architecture
SOSA™, CMOSS, and VITA-aligned design enables interoperability, rapid technology insertion, and reduced lifecycle risk.
High-Performance Computing
Supports SBCs, GPUs, RF, and networking payloads for AI/ML, mission processing, and real-time analytics.
Rugged by Design
Engineered to MIL-STD-810, 1275, 461, and 2404 standards—operable in the harshest environments.
Scalable & Configurable
Available as a chassis kit or fully integrated subsystem to support evolving mission and platform requirements.
Open Architecture Advantages
THOR is architected from the ground up to support SOSA™, CMOSS, and VITA standards, enabling true modularity and interoperability across platforms and vendors. This open systems approach reduces vendor dependency, lowers lifecycle costs, and enables continuous technology refresh without full system redesign.
- Rapid integration of third-party compute, GPU, RF, and networking modules
- Accelerated technology refresh cycles without full platform redesign
- Reduced lifecycle cost and minimized vendor lock-in
- Alignment with U.S. Army, Joint, and coalition modernization initiatives
By leveraging OpenVPX (VITA 65), THOR aligns with a growing ecosystem of interoperable COTS modules, allowing technology investments to scale across defense, aerospace, and industrial markets while reducing development risk and sustainment burden.
High-Performance Computing Where It Matters
THOR supports a broad range of compute and acceleration options to meet demanding mission and operational workloads.
- Intel®, Arm®, and NVIDIA®-based single board computers (SBCs)
- High-performance GPUs for AI/ML inference and video analytics
- RF, SDR, and DSP payloads for electronic warfare and communications
- High-speed Ethernet switching with Time Sensitive Networking (TSN) support
With internal data rates up to 100Gbps and support for dual-enclave architecture, THOR enables secure, low-latency data movement across mission applications. The same PCIe and Ethernet switched fabrics that support tactical compute also enable the real-time processing demands of robotics, automation analytics, and machine vision environments where latency and reliability are non-negotiable.
Engineered for Harsh Environments
THOR is designed to operate where traditional commercial systems cannot. The chassis meets rigorous military environmental requirements while supporting high-power processing in confined, weight-sensitive spaces.
- Conduction-cooled and fan-cooled thermal management options
- Support for power levels up to 600W
- Compliance with MIL-STD-810, MIL-STD-1275, MIL-STD-461, and ATPD-2404
- VITA-compliant chassis management and power distribution
- Nuclear hardening capability
This rugged design equally enables reliable deployment across factory floors, rail systems, mobile inspection platforms, and outdoor infrastructure subject to shock, vibration, temperature extremes, and continuous duty cycles.
Scalable from Chassis to Integrated Solution
THOR is available as a configurable chassis kit or as part of a fully integrated Leonardo DRS solution. Customers can scale from hardware-only deployments to complete subsystems incorporating DRS computing, sensors, software, and secure communications—tailored to mission requirements.
- Rapid prototyping and evaluation configurations
- Reduced integration risk through validated open-standard interfaces
- Clear growth path from demonstration to full-rate production
- Long lifecycle deployments with incremental upgrades—no platform redesign required
Built for the Tactical Edge
THOR delivers high-density embedded computing in a compact, rugged form factor optimized for deployment where it matters most.
From command and control to sensor fusion and AI-enabled decision support, THOR provides the processing backbone required to operate in degraded, denied, and contested environments. These applications and others all benefit directly from THOR’s ability to meet military grade ruggedization and reliability standards.
Defense Mission Applications
- Command and Control (C2) and Battle Management Systems
- Tactical Edge Compute (TEC) and AI/ML inference acceleration
- ISR, EO/IR, and multi-sensor data fusion
- Electronic Warfare (EW), SIGINT, and RF signal processing
- Assured Positioning, Navigation, and Timing (APNT)
Commercial & Industrial Applications
The compute density, ruggedness, and reliability engineered into THOR for military operations translate directly to demanding non-defense environments requiring deterministic, continuous performance:
- Industrial automation and advanced robotics control systems
- Machine vision and high-speed precision inspection platforms
- Railway, transportation, and infrastructure monitoring systems
- Scientific instrumentation and field-deployable research platforms
