Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1581 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
A single NVIDIA DGX GB300 at the Naval Postgraduate School in Monterey, California: one rack-scale unit that pairs 36 Grace CPUs with 72 Blackwell Ultra GPUs, a count given in NPS's own release and repeated by ExecutiveGov. NVIDIA donated it to the NPS Foundation, which installed it at the school and funds research projects that need its compute and memory; it supports the NPS-NVIDIA cooperative research and development agreement announced in December 2024. It was formally launched at a ribbon-cutting on 22 July 2026 attended by Jensen Huang, and NPS describes it as the first DGX GB300 in the US military. Vertiv, DDN and VAST Data contributed infrastructure, storage and technical help, but the release does not say which vendor supplied which part, so no storage or cooling edges are recorded. No power draw, benchmark or FLOPS figure is published; ExecutiveGov says it runs inside the school's existing power and water infrastructure. Stated uses are weather modeling, oceanic and operations research, cybersecurity and disaster response. Reported tier: both pages trace to the same NPS announcement.
