How to bid on Electro-Optical Sight Systems (EOSS) for the Dept of the Navy

Dept of the Navy INCloses August 7, 2026

What the Navy is buying and why it matters

The Department of the Navy is looking for proposals to replace the MK20 MOD 1 Electro-Optic/Infrared (EO/IR) Sight System (EOSS). This system is used on various US Navy and US Coast Guard ships with Gun Weapon Systems.

The current EOSS faces obsolescence risks and issues due to limited sources and its architecture. The Navy needs updated systems that incorporate Modular Open System Architecture (MOSA), improved Mean Time Between Failure (MTBF), and Motion Industry Standards Board (MISB) standards. This is an opportunity for vendors to provide critical technology to support naval and coast guard operations.

Key dates and what happens at the deadline

This Request for Solutions (RFS) was published on July 08, 2026. The deadline for submitting proposals is August 07, 2026, at 2:00 PM ET. All proposals must be submitted by this time.

The government intends to evaluate solutions and award a Project Order under the Expeditionary Missions Consortium (EMC2) Other Transaction Agreement (OTA).

Who this opportunity suits

This opportunity is for professional services firms specializing in electro-optical/infrared sight systems and related defense technology. Vendors must be members of the Expeditionary Missions Consortium (EMC2) to respond to this RFS. Information on EMC2 membership can be found on emccrane.org.

The project will be managed by a Naval Surface Warfare Center, Crane Division Project Manager.

Practical tips for a competitive response

Since this is a replacement project, clearly address how your proposed solution resolves the obsolescence risks and issues of the current MK20 MOD 1 system. Highlight how your technology improves upon the existing limitations.

Emphasize your solution's adherence to the required updated performance criteria, specifically Modular Open System Architecture (MOSA), Mean Time Between Failure (MTBF), and Motion Industry Standards Board (MISB) standards. Provide concrete examples or data to support these claims. Ensure your proposal clearly outlines your firm's experience and capabilities in developing and integrating advanced EO/IR sight systems for military applications.
