Defense Solutions — SysML v2 & UAF Platform
Integrated model-based engineering and architecture platform for defense-oriented enterprise, mission, system, and system-of-systems design
Overview
Defense Solutions is an integrated model-based systems engineering (MBSE) platform that converges SysML v2 modeling and Unified Architecture Framework (UAF) viewpoint authoring into a single workspace for defense architecture teams. As of v1.3 (2026-05-01), the platform delivers **24 capabilities** spanning the SysML v2 + UAF workflow: **23 are 🟩 Delivered with E2E verification pending** (the features are shipped and operational — 124 Playwright spec files are authored and a single results run promotes them to 🟢), and **1 is 🟡 partially delivered** (R08 Low-Code Authoring code-generation engine). Customer-visible capabilities cover visual diagram authoring with Yjs CRDT real-time collaboration, textual SysML v2 notation editing with KerML parsing, standard format import/export (XMI, SysML v2, UAF), AI-assisted systems engineering with provenance tracking, digital thread integration, DoDI 5000.97 acquisition lifecycle alignment with the full AAF pathway catalog, SysML v1→v2 migration tooling, mission engineering (scenario/vignette/MET modeling), offline/air-gapped operations with signing-key fail-fast, MBSE phase-gate lock-and-approve workflow, change-request impact analysis via BFS traversal, UAF capability scoring, and classification-marked defense document generation. The platform runs as a **single FastAPI application against a unified PostgreSQL database** (platform / sysml / uaf schemas) and is Azure Commercial deployment-ready.
Why Defense Solutions
Executive View
Defense Solutions integrates SysML v2 modeling, UAF viewpoints, requirements tracing, and acquisition milestone tracking into a single platform — so systems engineers work in one governed workspace instead of synchronizing across separate tools. Cross-viewpoint traceability ensures that changes in requirements propagate through structure, behavior, and mission models automatically, keeping programs aligned with JCIDS and DoDI 5000.97 at every milestone. Offline/air-gapped operations support SCIF environments where classified modeling occurs without network connectivity.…
Technical Architecture
The platform uses React 18 + TypeScript + Vite for the unified SPA frontend, with Cytoscape.js for diagram visualization and a feature-module architecture (canvas, textual-editor, import-export, migration, low-code-authoring, mission-engineering, offline, integration-hub, compliance, ai-agents). The backend is Python 3.12 + FastAPI with 25+ contexts across the unified platform shell and two sub-product backends (SysML_Models, UAF_Views). PostgreSQL 16 with Alembic migrations provides persistence with schema-per-context isolation.…
User Experience
Systems engineers author SysML v2 models on an interactive visual canvas with drag-and-drop diagram creation for Block Definition, Internal Block, Activity, Requirement, and State Machine diagrams — with real-time multi-cursor collaboration and undo/redo. For precision modeling, the textual notation editor provides KerML syntax highlighting and validation with round-trip to the visual canvas. UAF viewpoint authors work across all 7 viewpoints (Strategic, Operational, Services, Personnel, Resources, Security, Projects) with automated view generation.…
