Terrestrial Government Reference Architecture (T-GRA)
Welcome to the official hub for the Terrestrial Government Reference Architecture (T-GRA). While mission systems are frequently associated with airborne and sea-borne platforms, terrestrial systems—from Mission Planning to Maintenance Management Systems (MMS)—are the backbone of operational readiness.
Our focus is on creating open architectures for the software and hardware that drive ground-based support and sustainment of the warfighter. T-GRA ensures that terrestrial infrastructure is as agile, modular, and interoperable as the platforms it supports.
The T-GRA standard is not available at this time. Please check back for updates.
Core Focus Areas
T-GRA defines the standards for ground-based mission support systems, focusing on three primary pillars of terrestrial operations:
- Maintenance Management (MMS) Open architectures for logistics, health monitoring, and predictive maintenance.
- Mission Planning Standardized data formats and interfaces for rapid mission tailoring and rehearsal.
- Air-Ground Communications Open architectures for secure and reliable command and control between systems.
- Interoperability Secure “connected by default” philosophy to enable interoperability with external communities—e.g., weather, intelligence, maintenance, etc..
Why T-GRA?
T-GRA is designed to unify the terrestrial ecosystem, reducing fragmentation and accelerating the delivery of ground-based capabilities.
Standardized Sustainment
Unify maintenance protocols across diverse equipment sets.
Digital Continuity
Ensure seamless data flow from mission planning to execution.
Rapid Reconfiguration
Adapting ground support systems at the speed of modern warfare.
