What It Is / How It Works

OSS packages high-density GPU and PCIe compute for environments commercial servers cannot tolerate: shock, vibration, altitude and tight bay volumes. It sells at the rack/server tier, in contrast to VPX module vendors such as Mercury Systems and Curtiss-Wright.

Navy programs. On 2025-02-28 OSS announced $6M of renewals: $4M for P-8A Poseidon radar processing (five-year support extension, NVMe storage and data-transport software) and $2M for Virginia-class sonar processing, which the report describes as extending a sole-source role dating to 2010. On 2026-02-19 it announced $10.5M of new P-8A awards.

USSOCOM CRADA. OSS has a Cooperative Research and Development Agreement with US Special Operations Command to develop rugged HPEC solutions for maritime platforms. A CRADA is a joint R&D mechanism, not a production contract; the announcement date was not confirmed (a TipRanks page was last updated 2025-05-29).

Tamarack-G. On 2026-10-12 OSS unveiled Tamarack-G, described as a next-generation OCP/VPX hybrid system, at AUSA 2026. The press-release index reviewed gives no specifications.
