Why It Matters
The federal oceanographic research vessel fleet has had no government-wide inventory since March 2016, and NOAA's 15 remaining research and survey vessels average more than 30 years of age, with six expected to reach end-of-service life by 2030, according to a new Congressional Research Service (CRS) report.
Congress directed NOAA in P.L. 119-60 to submit a fleet replacement and modernization plan within 180 days of Dec. 18, 2025, a deadline that fell around June 16, but congressional committees have not yet received it.
The Big Picture
More than 10 years have elapsed since the Interagency Working Group on Facilities and Infrastructure last published a government-wide fleet status report. The working group began preparing an update in 2023, and NOAA acknowledged in 2024 that work was ongoing, but provided no timeline.
Of the 35 vessels inventoried at the end of fiscal 2015, NOAA owned 16, the Office of Naval Research owned 6, the National Science Foundation (NSF) owned 5, the U.S. Coast Guard owned 2, and 6 were owned by nonfederal entities. The 2016 report projected the fleet would shrink to 22 ships by fiscal 2030 with congressional investment, versus 18 ships without it.
Several vulnerabilities have emerged since that inventory:
- CGC Healy suffered a significant engineering casualty in July and could not complete its planned high-latitude summer mission, and the futures of both Healy and CGC Polar Star remain unclear.
- NSF's three new Regional Class Research Vessels are running behind schedule, per a Government Accountability Office finding cited in the report, and are not expected to begin operations until 2027–2029.
- The Navy's 30-year shipbuilding plan excludes oceanographic ships, and plans for replacing three existing auxiliary general oceanographic research vessels remain unclear.
Executive Order 14269 of April 9, 2025, "Restoring America's Maritime Dominance," is described in the report as intended in part to help the United States compete with China in ocean research. The report describes China's fleet as comprising more than 40 oceanographic research vessels, which it calls the world's largest, and presents stakeholder concern that data collected by those vessels may also serve military purposes as a concern, not an established finding.
The Bottom Line
NOAA's fleet replacement and modernization plan was due on or around June 16, and as of the CRS report's October 28 publication, Congress had not received it. S. 4784, a Senate-introduced fiscal 2027 National Defense Authorization Act, would bar retiring Navy oceanographic vessels without a replacement and require a report on new Global-class AGOR ships. The House-passed H.R. 4275, the Coast Guard Authorization Act of 2025, has been pending in the Senate Committee on Commerce, Science, and Transportation since July 23, 2025.
