Plug and Play Capabilities With Open Standard Boards

The chassis is designed to fit within the SINGCARS radio space in any vehicle or platform. It collapses several different capabilities (APNT, Radio, EW) into one system featuring individual slots where 3U VPX processor cards can be inserted and upgraded rapidly with a variety of capabilities. The system is also designed to support the Future Long-Range Assault Aircraft as well as other aviation assets without the need for costly modifications.

The CMOSS system will run advanced battlefield software from Palantir, Anduril, and Sierra Nevada Corporation to enable Next Generation Command and Control (NGC2) during Project Convergence Capstone in 2026. The system has already run with cards from more than 20 different vendors, including Abaco, Behlman Electronics, and Pacific Defense, with more to come and is built with support from LCR Embedded Systems. The Army can now continuously develop, test, and field capability in DevSecOps mode.

The CMOSS system resists threats through NSA-certifiable muti-level security, HEMP/EW hardening, and full tactical ruggedization.
