About this file
This is a quick start guide for the Weapons Government Reference Architecture (GRA) v5.1, released September 30, 2025, by the Digital Acquisition & Sustainment Operations (DASO) office under AFLCMC/EBRD at Eglin Air Force Base, Florida.
The Weapons GRA v5.1 is delivered as a collection of Cameo SysML models designed to support weapons systems engineering and acquisition. Key components include: the Government Issued Framework (GIF) model for conveying program requirements and reusable elements; the Implementation Hub (iHub) for data storage and artifact management; program office and contractor information modules; open standards for weapons communication (WOSA v3.5); interface definitions including the Universal Armament Interface (UAI) and Common Flexible Weapons ICD (CFWICD); classification marking guidance; annexes for higher classification content; a USG-only GovHub workspace; and a Library providing tools, templates, and profiles for systems engineering processes. The guide outlines a four-step implementation process: requesting access via the Weapons GRA Request Form, reviewing overview videos from SharePoint or DoD SAFE, opening the 01 GIF mdzip file in Cameo and reviewing the Start Here page, and opening the 02 iHub mdzip file to access the Start Here page and Home section. Questions regarding the Weapons GRA v5.1 should be directed to the DASO GRA team at aflcmc.ebr.dasoweaponsgra@us.af.mil.

Weapons GRA v5.1 Quick Start Guide
Weapons Government Reference Architecture (GRA) v5.1 Released 30 Sep 2025 Digital Acquisition & Sustainment Operations (DASO), AFLCMC/EBRD, Eglin AFB, FL
What is the Weapons GRA?
Weapons GRA v5.1 is delivered as a set of Cameo .mdzip SysML models:
• 01 [Program] GIF – Government Issued Framework; Tailorable model to convey program requirements and reusable model elements
• 02 [Program] iHub – Implementation Hub; Common organization to store data, contribute artifacts and establish data relationships
• Program Office Information – Provides program office information (e.g., POCs and weapon data)
• Contractor Information – Provides contractor name, logo and POCs to tools and iHub
• WOSA – Open standard for internal weapons communication – v3.5 for Cameo R22
• Common Flexible Weapons ICD (CFWICD) – Augments UAI with air-to-air and other messages
• Universal Armament Interface (UAI) – Defines common aircraft-to-weapon interface for air-to-ground weapons
• Data and Classification Markings – Provides marks and guidance for marking model elements
• 01A [Program] GIF Annex – Model for higher classification GIF content
• 02A [Program] iHub Annex – Model for higher classification iHub content
• GovHub – a USG-only model workspace and tools
• Library – Provides all tools, templates, profiles, and other necessary resources to execute specific Systems Engineering processes within the GRA. Built to reduce model interdependencies and facilitate future model updates. V5.0 is centered around providing this functionality.
