How Modular Computing Is Accelerating Modern Defense Technology

April 20, 2026

Modern defense platforms are evolving rapidly, with modular computing emerging as a key enabler of that transformation.

On this episode of the Aerospace & Defense Technology podcast, Shaun Fischer, Director of Development and Open Systems Solutions at Leonardo DRS, discusses the company’s newly launched THOR — Tactical, High‑Performance Embedded Computing, Open Architecture, Rugged — embedded computing chassis and the new military applications it is designed to enable. THOR 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.

Fischer also explains how the chassis aligns with the Modular Open Systems Approach (MOSA), the open‑architecture initiative shaping the acquisition of next‑generation defense technologies.
