SOLICITATION ANNOUNCEMENT: AN/BYG-1 APPLICATIONS

The Department of the Navy, Naval Sea Systems Command (NAVSEA), on behalf of the Portfolio Acquisition Executive for Undersea (PAE Undersea) and the Director, Submarine Programs (DSP), is releasing the formal solicitation for the AN/BYG-1 Applications requirement from the Submarine Combat and Weapons Control Program Office (PMS 425).

This notice follows the previously published Draft Request for Proposal (RFP) and Industry Day event. The Government has reviewed the feedback received during and after the Industry Day and has revised the requirements accordingly for this final solicitation.

SCOPE OF THE REQUIREMENT (GENERAL OVERVIEW)

AN/BYG-1 is the U.S. Navy’s Submarine Combat Control System. The AN/BYG-1 provides tools for the analysis of surface, sub-surface, and airborne contacts operating in the vicinity of own-ship and within the mission theater. This analysis supports command and decision-making, payload and attack control functions, determination of ballistic data for legacy torpedoes, and initiation of firing sequence for all payload types in support of submarine mission areas.

The scope of this solicitation encompasses the development, testing, integration, delivery, logistics, and full-lifecycle sustainment of compiled AN/BYG-1 software baselines. This includes current, future, and legacy AN/BYG-1 applications as part of a modernized capability delivery framework. Key objectives and technical efforts under this contract include:

• Deliver AN/BYG-1 capabilities and baselines in alignment with Submarine Tactical Requirements Group priorities
• Decouple AN/BYG-1 applications from hardware and software dependencies
• Implement microcontainer/microservices AN/BYG-1 architecture
• Transform AN/BYG-1 development and test environments by increasing virtualization and establishing a common, shared infrastructure
• Develop and integrate tactical decision aids that leverage artificial intelligence and machine learning technologies
• Assist with the design, development, and integration of combat control system elements to support international cooperative agreements and joint programs.
