What Happened?

NOAA's 15 remaining research and survey vessels average more than 30 years old, and six are expected to reach the end of their service life by 2030, according to a Legis1 review of a new Congressional Research Service (CRS) report. The CRS published its report on October 28. ​

The National Oceanic and Atmospheric Administration (NOAA) operates 15 research and survey vessels that average more than 30 years of age. The federal government has had no government-wide fleet inventory since March 2016, and an interagency update begun in 2023 had no timeline as of 2024.

Why Does it Matter to Me?

Congress required NOAA by law to submit a fleet replacement and modernization plan within 180 days of Dec. 18, 2025, a deadline that fell around June 16. As of the CRS report's Oct. 28 publication, that plan was roughly 134 days overdue.

Other gaps documented in the report:

  • Coast Guard icebreakers: CGC *Healy* suffered a major engineering casualty in July and could not complete its high-latitude mission; the futures of both *Healy* and CGC *Polar Star* remain unclear.
  • New science ships delayed: The National Science Foundation (NSF) has three new Regional Class Research Vessels running behind schedule and not expected to begin operations until 2027–2029.
  • Navy gap: The Navy's 30-year shipbuilding plan excludes oceanographic ships, and replacement plans for three existing research vessels remain unclear.

Both Sides, Now

The CRS report describes China's oceanographic fleet as comprising more than 40 research vessels, which it calls the world's largest. Executive Order 14269, signed April 9, 2025 and titled "Restoring America's Maritime Dominance," is described in the report as intended in part to help the U.S. compete with China in ocean research. Congress did not authorize that order; it is an administration action.

The report presents concern that Chinese research vessels may also serve military purposes as a stakeholder concern, not an established finding. A France 24 report found that while Chinese research ships attracted scrutiny from Australia and the Philippines, "there is no evidence that [spying] is taking place at this time."

What Happens Next?

If Congress follows the 2016 report's projections, the federal oceanographic fleet could shrink to 22 vessels by fiscal 2030 with investment, or to 18 without it.

A Senate bill included in a fiscal 2027 defense policy package would bar the Navy from retiring oceanographic vessels without a replacement and would require a report on building new Global-class research ships.

The Coast Guard Authorization Act of 2025, passed by the House, has been waiting in the Senate Commerce, Science, and Transportation Committee since July 23, 2025. NOAA's overdue fleet modernization plan must still be delivered to Congress before lawmakers can act on the broader funding question.
