Submarine Maintenance Delays Decline Sharply in FY26, Czar Reports

WASHINGTON — Submarine maintenance delays saw a substantial reduction in fiscal 2026, with a decline of over 600 days compared to prior years, according to the Pentagon’s inaugural submarine czar.

Vice Adm. Rob Gaucher, Director of the Submarine Direct Reporting Portfolio, noted that the fleet experienced approximately 1,400 days of maintenance delay in both fiscal years 2024 and 2025, but that figure fell to 780 days in fiscal year 2026.

Gaucher emphasized the notable decline in maintenance days during his remarks at the Naval Submarine League Annual Symposium on Thursday, adding that the improvement exceeded 40 percent.

He credited much of this progress to recent investments in Virginia‑class spare parts, and projected that maintenance delays will fall to roughly 500 days in fiscal year 2027.

Gaucher highlighted the Virginia‑class submarines John Warner and Illinois, which are slated for depot maintenance in the coming weeks. Although their delivery dates were originally delayed, both vessels are now several months ahead of their revised timelines — a milestone the service could not have achieved a few years ago, he said.

He explained that the Navy had to revise delivery schedules multiple times, and that achieving early re‑baselining represents significant progress. As of now, all fast‑attack submarines at Portsmouth and Pearl Harbor Naval Shipyards are on schedule, with several even running ahead of plan.

The Navy has historically faced persistent submarine maintenance delays, and an August Government Accountability Office report found that public shipyards — responsible for maintaining nuclear-powered vessels such as submarines — completed just 11 percent of depot maintenance periods on schedule between fiscal years 2016 and 2025.
