Fluor Marine Propulsion LLC received a $2.4 billion modification to a previously awarded Navy contract for Naval Nuclear Propulsion work at government-owned facilities. The award, disclosed in federal contract records on October 23, 2026, was the largest single federal contract action tracked by SecBot that week.
The award in detail
The modification (P00013 to contract N0002418C2130) was issued by the Department of the Navy to Fluor Marine Propulsion LLC, an Arlington, Virginia-based subsidiary of Fluor Corporation. The contract action is structured as a cost-plus-fixed-fee modification valued at $2,409,077,590. The work covers Naval Nuclear Propulsion activities at government-owned facilities under the Naval Nuclear Propulsion Program.
The award was one of several large defense awards published on October 23, but it dwarfed the others in size.
Other large awards that same day
The same batch of federal contract records included several other notable awards. Lockheed Martin Aeronautics Co. received a $114,629,966 cost-plus-fixed-fee order against a previously issued basic ordering agreement for the F-35 Lightning II program. Northrop Grumman Systems Corp. was awarded a $43,856,500 firm-fixed-price contract to support the design of new rocket motor dry and grind production facilities. Vitol Aviation Co. received a $230,101,364 contract from the Defense Logistics Agency for fuel. Amentum Services Inc. received a $26,096,110 modification for Air Forces Central aviation support.
The Fluor award alone was more than 10 times the size of the next largest award in that day's disclosures.
Fluor's role in the Naval Nuclear Propulsion Program
Fluor Marine Propulsion is a key contractor in the Naval Nuclear Propulsion Program, which designs, builds, operates, and maintains the nuclear reactors that power U.S. Navy aircraft carriers and submarines. The program is managed jointly by the Department of Energy and the Department of the Navy. Fluor's work under this contract covers operations at government-owned naval nuclear propulsion facilities, including the Knolls Atomic Power Laboratory and the Bettis Atomic Power Laboratory, where the company provides design, development, testing, and support services.
The modification extends and expands the scope of work under a contract that was originally awarded in fiscal year 2018. The cost-plus-fixed-fee structure means Fluor is reimbursed for allowable costs plus a fixed fee, a common arrangement for long-term nuclear and defense programs where costs cannot be precisely estimated at the outset.
What the data does not show
Federal contract records show the announced value of the modification but do not specify the period of performance or the exact scope changes that triggered the increase. The modification number P00013 indicates this is the 13th change to the base contract since its original award, but the records do not break down cumulative spending under the contract. The data also does not disclose whether the modification funds new work, extends the period of performance, or adjusts funding for ongoing activities.
The contract records do not include Fluor's financial statements or backlog figures, so the modification's impact on Fluor's revenue pipeline cannot be calculated from this data alone. Fluor Corporation reports its government services revenue in quarterly SEC filings, and the next quarterly report will provide context on how this modification flows through the company's financial statements.
Other defense contractors with large awards
The October 23 batch of federal contract records also included a $42,758,897 award to Vigor Marine LLC for a shipyard availability for the regular overhaul and drydocking of a Navy vessel, and a $49,000,000 multiple award contract addition for Cepheid for laboratory equipment and consumables.
What to watch
Fluor's stock price and the company's next earnings report will show whether this modification was already included in the company's guidance or represents new backlog. The modification is the largest single contract action for Fluor in the current data window, and more than ten times the next largest award disclosed that day. The Department of Defense's daily contract announcements and Fluor's SEC filings will provide updates on the Naval Nuclear Propulsion contract's total value and period of performance.
