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. It delivers 19 fully tested capabilities covering visual diagram authoring (5 SysML + 2 UAF types with 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, SysML v1→v2 migration tooling, mission engineering (scenario/vignette/MET modeling), and offline/air-gapped operations with conflict resolution. The platform completed all 4 convergence phases (platform foundation, UAF absorption, interaction modernization, agent/automation maturity) and all 10 development process phases from initialization through operations handoff.
Why Defense Solutions
Executive View
Defense Solutions eliminates the tool fragmentation that plagues defense MBSE programs. Today, systems engineers use separate tools for SysML modeling, UAF viewpoints, requirements tracing, and acquisition milestone tracking — creating manual synchronization overhead and traceability gaps that risk JCIDS and DoDI 5000.97 compliance. Defense Solutions unifies these workflows into one platform with cross-viewpoint traceability, ensuring that changes in requirements propagate through structure, behavior, and mission models automatically.
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.
