The Naval Sea Systems Command plans to modify Contract N00024-21-C-6425 with General Dynamics Mission Systems to add 42,000 hours of engineering support services for the Hammerhead Program, a moored-torpedo mine system designed to detect, classify, and neutralize anti-submarine warfare targets. As the sole prime contractor and systems integrator awarded under a 2021 competitive contract, GDMS holds exclusive technical knowledge, proprietary data, and active security clearances essential to advancing the Hammerhead system’s current configuration modifications. Without this increase in engineering support, critical development work on the MOD 1 variant will stall, preventing finalization of the Technical Data Package and blocking the transition to production, which would severely delay delivery of this vital capability to the Fleet. The modification is justified under statutory authority permitting sole-source awards when only one source can satisfy the government’s requirements, as competing the work would cause an estimated 24-month delay due to source selection, knowledge transfer, and facility setup. Such a delay would directly undermine national security timelines and operational readiness. The government will obtain Government Purpose Rights to the validated Technical Data Package, preserving future flexibility for potential competition, but current urgency necessitates maintaining continuity with the existing contractor. This action is not a competitive solicitation, though responsible sources may submit capability statements by the July 5, 2026 deadline to be considered at the government’s discretion. The primary point of contact for submissions is Steven Noel, and the work will be performed in Taunton, Massachusetts, under the jurisdiction of the Department of Defense.

Description


The Naval Sea Systems Command (NAVSEA) intends to award a sole-source modification to Contract No. N00024-21-C-6425 with General Dynamics Mission Systems (GDMS). This action will increase the Engineering Support Service (ESS) ceiling by 42,000 hours to support the Hammerhead Program.


The Hammerhead is a moored-torpedo variant mine system capable of detecting, classifying, and defeating Anti-Submarine Warfare (ASW) targets. Under a competitively awarded 2021 contract, GDMS is the prime contractor and sole systems integrator responsible for the design, development, and production of the Hammerhead system.


The Department of the Navy requires these additional ESS hours to support critical program requirements and engineering changes for modified configuration(s) that are a logical technical progressions of the baseline system. Without this increase in engineering support, configuration effort will halt, which will preclude the commencement of the production phase and cause a failure to deliver this critical capability within the Fleet’s required timeline.


Statutory Authority and Justification for Other Than Full and Open Competition


The proposed contract action is being solicited pursuant to 10 U.S.C. § 3204(a)(1), as implemented by FAR 6.302-1, "Only one responsible source and no other supplies or services will satisfy agency requirements."


GDMS is the only responsible source capable of providing the required ESS for the Hammerhead system without causing unacceptable delays in fielding a critical capability. As the current prime contractor, GDMS possesses the active facility clearances, proprietary technical data, and specialized knowledge of the Hammerhead system architecture required to perform the work immediately.


Competing this requirement would result in an estimated 24-month cumulative delay due to the time required for source selection, knowledge transfer, and facility stand-up. Such a delay would halt ongoing engineering efforts on the critical MOD 1 configuration, preventing the finalization of the Technical Data Package (TDP) and delaying the transition to production, thereby compromising the Navy’s ability to meet national security requirements.


The Government will obtain Government Purpose Rights (GPR) to a validated Hammerhead TDP, which may allow for future competition of Hammerhead requirements.


Capability Statements / Submission Instructions


This notice of intent is not a request for competitive proposals. However, all responsible sources may submit a capability statement, proposal, or quotation, which shall be considered by the agency. Interested parties are invited to submit a response demonstrating their ability to provide the required services. A determination by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the Government.


Responses to this notice must be received by 4:00 PM Eastern Time on the response date stated in this posting. Responses shall be submitted via email to the Primary Point of Contact listed below and must reference this notice ID in the subject line.

USS MAKIN ISLAND (LHD 8) FY28 Docking Selected Restricted Availability (DSRA) Request for Proposal(s)
Solicitation # N0002426R4421
The Naval Sea Systems Command (NAVSEA) is soliciting solicitation N00024-26-R-4421 for the USS MAKIN ISLAND (LHD 8) Fiscal Year 2028 Docking Selected Restricted Availability (DSRA). This Signature Availability involves a comprehensive scope of maintenance, modernization, and repair, including hull structure work, propulsion and electric plant repairs, auxiliary system overhauls, and structural welding. The project requires a contractor with substantial West Coast facilities, specifically a capable pier and dry-dock for the LHD ship class, as well as the ability to provide a resource-loaded integrated production schedule. The government intends to make a single firm-fixed-price award in or before March 2027, with the period of performance beginning in November 2027 and concluding in October 2029. Due to the complexity and magnitude of the requirements, this procurement is not set aside for small businesses. Interested offerors must be registered in the System for Award Management (SAM) and are encouraged to possess a NAVSEA Tier 1 Master Ship Repair Agreement (MSRA) and Agreement for Boat Repair (ABR). Proposals are due by November 9, 2026, and must be submitted electronically via PIEE. For the growth CLINs, the level of effort is estimated at 103,400 labor hours and 5,576,780 dollars in materials. Access to detailed CDRLs and technical attachments must be requested through the designated Contract Specialist and Contracting Officer.

AN/BYG-1 Applications
Solicitation # N0002426R6222
The Department of the Navy, through the Naval Sea Systems Command (NAVSEA), is soliciting proposals for the AN/BYG-1 Applications requirement under solicitation N00024-26-R-6222. The AN/BYG-1 serves as the U.S. Navy's Submarine Combat Control System, providing critical tools for analyzing surface, sub-surface, and airborne contacts to support command decision-making and attack control functions. The scope of this effort includes the development, testing, integration, delivery, and full-lifecycle sustainment of compiled software baselines. Key technical objectives include implementing a microcontainer/microservices architecture, decoupling applications from hardware dependencies, increasing virtualization of development environments, and integrating artificial intelligence and machine learning for tactical decision aids. Due to the sensitive nature of the work, solicitation documents are designated as Controlled Unclassified Information and are available exclusively via the Electronic Technical Information Center (E-TIC) portal. Access requires a DoD CAC or approved ECA Certificate and an active Joint Certification Program registration. While a SECRET facility clearance is sufficient for proposal preparation and access to classified software source code, the successful offeror must possess a fully adjudicated TOP SECRET facility clearance and safeguarding capability by the time of contract award. Proposals must be submitted electronically via the PIEE Solicitation Module by October 19, 2026, at 4:00 PM Eastern Daylight Time.
