Software development has always been my happy place, and honestly what I love most about working in this industry is the ability to build out truly amazing and impactful solutions.
The defense industrial base is in the middle of a software development transformation that doesn’t get talked about in quite the right terms. Most of the conversation focuses on AI for analysis — decision support, targeting intelligence, logistics optimization. But the more consequential shift may be happening one layer below that: in how mission software itself gets built, tested, and deployed. The Department of War now has over 50 software factories using DevSecOps practices, and those factories are increasingly becoming AI-native. What started as a pipeline automation story is becoming something fundamentally different — a model where AI agents participate in the development lifecycle as active contributors, not just tools.
This is an exciting opportunity where we can do some very interesting things to bring innovation to the Defense Industry.
The concept at the center of this shift is something I’ve been calling “build low, deploy high.” The core idea is straightforward: you build and test your AI-assisted development workflows in unclassified or CUI environments, then deploy the validated code and AI inference capabilities into classified networks where they operate without external connectivity. The infrastructure to support this model now exists end-to-end with Microsoft’s stack. GitHub Copilot and Azure AI Foundry serve as the development-side platform. Azure Government Secret (IL6) and Azure Government Top Secret (IL7) provide the classified deployment targets. The Department of War’s May 2026 agreements with eight AI companies — including Microsoft — to deploy AI capabilities at IL6 and IL7 confirm that the classified side is ready to receive it.
What makes this practically achievable for development teams right now is the maturity of the tooling. GitHub Copilot CLI now supports BYOK and a dedicated offline mode — set COPILOT_OFFLINE=true and the CLI operates exclusively against your configured model endpoint, with all telemetry disabled. VS Code Agents reached stable in May 2026, with the same air-gapped capability: point it at your own model, no external network required. The GitHub Copilot SDK hit general availability in June 2026, available in six languages, with BYOK support that lets teams embed the full Copilot agentic engine — planning, tool invocation, multi-turn sessions — into custom applications pointed at Azure Government OpenAI or locally hosted models. This isn’t a roadmap. These capabilities ship today.

Microsoft Foundry serves as the connective tissue for building development agents in this model. Azure AI Foundry Agent Service provides the orchestration layer for multi-agent workflows, supports open protocols like Model Context Protocol (MCP) and Agent-to-Agent (A2A) communication, and includes observability tooling for monitoring agent behavior in production. On the development side, the Copilot SDK exposes the same agent runtime behind Copilot CLI programmatically — so teams can build custom development agents that carry domain-specific knowledge about their mission systems, their security requirements, and their code standards. The human-in-the-loop model built into GitHub’s platform — mandatory pull request review, branch protections, CI/CD approval gates — provides the governance framework that defense programs require.
The convergence of these capabilities creates a genuine forcing function for the defense industrial base. Programs that invest now in AI-assisted development infrastructure — built on open, standards-based tooling like MCP and BYOK-compatible models — will have a significant velocity advantage over those that wait. The competitive frame here isn’t developer productivity in the abstract. It’s the ability to deliver mission software at the speed the Department of War is demanding: not in acquisition cycles measured in years, but in DevSecOps cycles measured in weeks. The “build low, deploy high” model, powered by GitHub Copilot and the Microsoft Foundry platform, is the architecture that closes the gap between commercial development speed and mission deployment requirements.
