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.
Beyond its operational capability, the QRF-4500-BC provides a rapidly available, Canadian-made and ITAR-free alternative for users seeking to field or supplement existing fire-control capabilities without relying exclusively on US-controlled supply chains. As an OEM, GSCI can support configuration, production, and sustainment directly, providing a scalable solution for programs requiring responsive delivery and long-term availability. The system addresses the equipment and decision burden associated with obtaining range, environmental data, orientation, and ballistic calculations from multiple separate devices. It also provides an alternative procurement pathway for organizations requiring rapid access to a mature, production-ready fire-control capability without dependence on US-controlled sourcing, at a more competitive/flexible price point.

The system combines a high-performance 12 µm thermal sensor, silent shutterless operation, and rugged all-aluminum construction in a highly compact form factor. Canadian manufacture and ITAR-free sourcing further provide a responsive alternative for organizations seeking flexible thermal capability without committing to separate purpose-built systems for every role.
