• Navy’s Horizon 0 mandates decommission before new tech funding
• Portfolio Acquisition Executives will track legacy divestment metrics
• Tying modernization budgets to retirement accelerates AI and JADC2 adoption

Pulse Analysis

The defense enterprise is caught in a costly paradox: billions of dollars flow into keeping Cold‑War‑era hardware and software operational, yet the same budget is expected to fuel next‑generation autonomous systems. Legacy platforms demand custom integration work, creating fragile, monolithic solutions that are vulnerable to cyber‑threats and impede rapid decision‑making. As adversaries like China modernize with open, cloud‑native architectures, the U.S. risks falling behind not because of a lack of technology, but due to the inertia of outdated contracts and infrastructure.

The Navy’s Investment Horizons model offers a pragmatic blueprint for breaking this inertia. By categorizing technologies into horizons, Horizon 0 explicitly calls for retirement of systems whose cost of upkeep exceeds their operational value. The "Cattle Drive" initiative operationalizes this by systematically decommissioning obsolete enterprise services, freeing budget and talent for innovative projects. Portfolio Acquisition Executives (PAEs) are positioned to embed this lifecycle thinking across the department, providing transparent dashboards that quantify legacy burdens and guide strategic divestment.

Scaling this approach department‑wide requires linking new capability funding to demonstrable legacy retirements. Contracts should stipulate that any modernization effort must include a sunset plan for the replaced system, with measurable milestones and allocated transition funds. Engaging commercial vendors to propose cloud‑native replacements can further accelerate the shift, turning legacy liabilities into opportunities for private‑sector innovation. By institutionalizing disciplined retirement, the DoD can reallocate resources toward AI, JADC2, and autonomous platforms, ensuring a more agile and resilient force for future conflicts.
