Electro-Optical Sight Systems (EOSS)

The US Navy and US Coast Guard are seeking to replace the MK20 MOD 1 Electro-Optic/Infrared (EO/IR) Sight System (EOSS) with a new system that incorporates updated performance criteria, including Modular Open System Architecture (MOSA), Mean Time Between Failure (MTBF), and Motion Industry Standards Board (MISB) standards. The new system should address the current obsolescence risks and issues associated with the existing EOSS. • The RFS is open to members of the Expeditionary Missions Consortium (EMC2). • The project will be managed by a Naval Surface Warfare Center, Crane Division Project Manager. • The selected solution will be awarded a Project Order under the EMC2 Other Transaction Agreement (OTA). • The RFS was released on 7 July 2026, and interested parties can find more information on the EMC2 website.
