Key Points

  • Pentagon Undersecretary for Acquisition Michael Duffey certified that a proposed fixed-price contract for nine Block VI Virginia-class submarines met legal requirements, according to a June 29 letter to the House Armed Services Committee.
  • The certification did not identify a contract value; the Navy's earlier nine-boat Block V award was valued at $22.5 billion. Duffey said the Block VI multi-year deal would save approximately $2.4 billion.
  • The Pentagon is advancing the award despite schedule shortfalls on the Block V program and a separate $2.6 billion May contract issued for parts and pre-construction tasks related to the upcoming contract.

Shares of General Dynamics Corporation (NYSE:GD) rose 1.2% on Tuesday following a report that the Pentagon had approved a proposed contract for the company to build nine next-generation attack submarines.

According to the report, Undersecretary for Acquisition Michael Duffey certified that the proposed fixed-price agreement for nine Block VI Virginia-class submarines satisfied applicable legal standards. The certification was conveyed in a letter sent to the House Armed Services Committee on June 29, the report said.

The letter did not state a contract value. For context within the program, the Navy's earlier award to General Dynamics for nine Block V Virginia-class submarines was valued at $22.5 billion. Duffey indicated the multi-year agreement for Block VI submarines would yield roughly $2.4 billion in savings.

The Defense Department is advancing the contract award despite acknowledged schedule difficulties with General Dynamics' prior order for nine Block V submarines. In May, the House Armed Services Committee observed that construction of Block V boats is falling short of the required delivery pace of more than two submarines per year.

Also in May, the Navy granted General Dynamics a $2.6 billion contract to cover parts and pre-construction work tied to the forthcoming Block VI award.

The broader Virginia-class submarine program has seen cost overruns and delays, the report noted, while the submarines themselves are designed to furnish strategic capabilities for the U.S. military.


Context and implications

The certification by the Undersecretary for Acquisition represents a formal step allowing the Pentagon to proceed with the fixed-price contract process for Block VI submarines. While the reported projected savings could affect program budgeting, the decision comes against a backdrop of performance shortfalls on the Block V production schedule and prior program cost and timing issues.

Market reaction to the certification was modestly positive for General Dynamics' shares, as investors priced the news into the stock. The Navy's prior $22.5 billion Block V award and the separate $2.6 billion May contract for parts and pre-construction work remain relevant reference points for assessing near-term program activity.

Risks

  • Schedule risk - Construction of Block V submarines has been reported as underperforming the required delivery pace of more than two vessels per year, which could affect timelines for Block VI and related industry production schedules.
  • Cost and delay risk - The Virginia-class program has experienced cost overruns and delays, presenting financial and timeline uncertainties for defense procurement budgets and contractors.
  • Contract execution risk - Proceeding with a new fixed-price multi-year contract while earlier program segments face schedule challenges introduces execution risk for shipyards, suppliers, and associated markets.
