Pentagon’s Most Advanced AI Supercomputer Goes Live at a Navy School in Monterey

The CEO of the world’s most valuable chipmaker stood next to the commander of U.S. Indo-Pacific Command at a Navy school in coastal California. That happened when NVIDIA’s Jensen Huang — tech’s closest equivalent to a stadium-touring rock star — joined Adm. Samuel Paparo to launch the Pentagon’s most powerful AI-focused supercomputer at Naval Support Activity Monterey. The system, an NVIDIA DGX GB300 built on “Grace Blackwell” architecture, pairs 36 Grace CPUs with 72 Blackwell Ultra GPUs. It sits on the NPS.edu network, running within existing base power and water infrastructure — no new data center required. According to Reuters, NVIDIA donated the hardware to the NPS Foundation through a cooperative research and development agreement that began in December 2024, marking the first direct use of NVIDIA’s most advanced servers by the U.S. military, part of a broader AI infrastructure race reshaping both Silicon Valley and Washington.

Built for AI, Not Just Number-Crunching

This machine is designed to build new models, not simply run the ones the military already has.

Traditional Pentagon supercomputers run known simulations at scale, but the Monterey system’s parallel architecture processes massive workloads simultaneously — think 72 video streams rendering at once rather than buffering one at a time — making it purpose-built for training AI models from scratch. Capt. Michael Owen, NPS’s vice provost for warfare studies, outlined what that unlocks:

logistics optimization for distributing “beans, bullets and all of the standard defense logistics things” across theaters

cybersecurity models trained to detect threats in military network traffic

weather prediction pushed far beyond the 50-kilometer resolution grids behind your evening forecast

“When you start talking about defense operations, your general weather modeling that you would see at your evening weather news or in the morning for your commute is just not adequate,” Owen told Military Times.
