How to bid on AN/BYG-1 applications for the Department of the Navy

What the Navy is buying

The Department of the Navy is seeking a contractor to develop, test, integrate, deliver, and sustain software applications and baselines for the AN/BYG-1 submarine combat control system.

The work includes modernizing the system with a microservices architecture, increasing virtualization in development and test environments, and developing AI/ML decision aids. The scope also includes logistics and full-lifecycle sustainment. This may suit firms with experience in secure software engineering, systems integration, testing, and long-term software support.

Key date and deadline

Proposals are due November 5, 2026, at 4:00 p.m. Eastern. The solicitation says the due date was extended in Amendment 002.

Plan to submit before the deadline and allow time to confirm the submission is complete. The solicitation states that proposal files must not be embedded inside other files, such as an Excel file embedded in a Word document.

Who this opportunity suits

This opportunity is for firms able to work on submarine combat-control software and manage development, testing, integration, delivery, and sustainment across current, future, and legacy applications.

The company needs a DCSA-issued Secret facility clearance and Secret safeguarding capability to request access for proposal preparation. For award eligibility, the offeror must have a fully approved Top Secret facility clearance and Top Secret safeguarding capability by contract award. The Government will not sponsor clearance upgrades for proposal submission or award eligibility.

How to access the solicitation and respond

The solicitation, Statement of Work, and unclassified attachments are CUI and are available through the secure E-TIC portal, not directly on SAM.gov. The classified software source code for proposal development is provided physically. To request E-TIC access and the classified package, submit one consolidated access-request email using the instructions in the solicitation.

The request must include a completed DD Form 254 showing Secret clearance and safeguarding capability, a current approved DD Form 2345, and an executed Terms of Use Agreement. The email must use the specified subject format and provide the company name and CAGE Code, the designated E-TIC representative’s name and contact details, and whether the company requests the classified source code.

Use the opportunity portal’s “View original source” option to reach the bid. If the first click opens the portal homepage, click again to go to the opportunity. A free account may be needed to view documents. Follow the solicitation’s Section L and current amendments for proposal submission instructions.

Prepare a clear, compliant proposal

Review the latest solicitation and Section L carefully, including the changes published in Amendments 001, 002, and 003. Check the amendment summaries and any question-and-answer material available to you so your response addresses the current requirements.

Organize the response around the stated work: software delivery and sustainment, decoupling applications from hardware and software dependencies, microservices, shared development and test infrastructure, and AI/ML decision aids. Explain your approach and relevant experience clearly, and check that every required file is separate rather than embedded inside another file.

Before submitting, verify that the proposal follows the solicitation’s instructions, that the required access and security arrangements are in place, and that the files can be opened and reviewed.
