The Pentagon's technology wallet has never been larger — and a growing slice of it is flowing directly toward artificial intelligence. The Department of Defense finalized an IT budget of $66 billion for fiscal year 2026, up $1.8 billion from the prior year, signaling sustained institutional commitment to modernizing military systems at a time when AI capabilities are increasingly treated as a strategic imperative rather than an experimental add-on.
For defense contractors, the stakes are clear: integrate AI into core offerings, or risk being outcompeted for the next generation of procurement contracts.
Strategic Partnerships Signal a New Competitive Baseline
One of the most closely watched moves came on February 17, when HII — one of the largest U.S. naval shipbuilders — signed a memorandum of understanding with Path Robotics to advance Physical AI in naval shipbuilding. Path Robotics, which has raised over $300 million since its founding, develops AI-driven robotic welding systems designed to work autonomously in complex, unstructured environments. The partnership positions HII to apply autonomous fabrication technology to shipbuilding workflows that have historically been difficult to automate.
The deal is emblematic of a broader pattern: established defense primes are not waiting for internal R&D cycles to deliver AI capabilities. Instead, they are partnering with or acquiring specialized AI firms to accelerate integration timelines and signal technological credibility to DoD procurement officers.
Separately, Curtiss-Wright was selected by Boeing for the C-17 Mission Computer Contract, with its MOSA-aligned (Modular Open Systems Approach) solution. MOSA compliance has become a procurement preference for the DoD precisely because it enables faster software updates and AI model deployment across platforms — making Curtiss-Wright's selection a meaningful indicator of how AI-readiness is reshaping contract award criteria.
Market Size Creates Long-Tailed Revenue Opportunity
The financial opportunity underlying these moves is substantial. The global AI-in-defense and aerospace market is currently valued at approximately $4.2 billion in 2026, but analysts project it will reach $42 billion within a decade. More specifically, the AI-in-military segment alone is valued at $22.41 billion in 2026 and is projected to exceed $101 billion by 2032 — a compound annual growth rate that would make it one of the fastest-expanding verticals in the broader defense sector.
These figures suggest the revenue differentiation between AI-integrated and non-AI-integrated contractors will compound over multiple budget cycles, not just the current one.
Early Financial Evidence: Howmet Aerospace's Q4 Results
While direct AI attribution in earnings remains difficult to isolate, Howmet Aerospace delivered a data point worth noting: the company reported 15% year-over-year revenue growth in Q4 2025, alongside record adjusted EBITDA, driven in part by strong aerospace demand. Howmet's results illustrate how contractors positioned along modernization themes — whether through AI, advanced manufacturing, or next-generation components — are already seeing financial outperformance relative to legacy-focused peers.
Investment Implications
For institutional and retail investors tracking the defense sector, the emerging thesis is increasingly testable: companies that disclose concrete AI integration in earnings calls and win AI-relevant procurement contracts may generate measurably superior forward revenue growth compared to matched peers without those capabilities. As DoD procurement databases become more granular in labeling AI-related awards, the ability to construct and validate such a portfolio strategy will improve.
The current budget cycle makes one thing apparent — the DoD is spending, and it is spending with a clear preference for contractors who can deliver intelligence alongside hardware.
