Quick Summary

The Department of the Navy / NAVSEA HQ has issued a Justification and Approval (J&A) for a sole-source contract award to General Dynamics Electric Boat (GDEB) of Groton, CT. This contract is for the Government-Owned Contractor-Operated (GOCO) Operation and Maintenance of the floating dry dock SHIPPPINGPORT (ARDM)-4 at Naval Submarine Base New London, CT.

Scope of Work

The contract covers the comprehensive operation, protection, and maintenance of the ARDM 4 floating dry dock. This includes critical support for returning mission-ready submarines to the Fleet and involves specialized radiological work associated with U.S. Naval Nuclear Propulsion Plants, requiring specific nuclear qualification and Navy certification.

Contract Details

Type: Cost-plus-fixed-fee, level-of-effort (CPFF-LOE)
Duration: One 12-month base period and four 12-month option periods
Anticipated Period of Performance: May 2026 through May 2031
Funding: Operations and Maintenance, Navy (O&MN) appropriations
Estimated Value: Specific figures are redacted, but an estimated total value is indicated.

Eligibility & Rationale

This is a sole-source award justified under 10 U.S.C. 3204(a)(1), citing that only one responsible source, GDEB, can satisfy the agency's requirements. Market research, including a sources sought notice (September 16, 2024) and a pre-solicitation notice (January 29, 2025) indicating intent to award to GDEB, confirmed that no other contractors responded or were deemed capable of meeting the specialized nuclear qualification and certification requirements.
