Inspections, by type
The 5 inspections in the strip above, split by the kind of activity the US
Coast Guard recorded. Years with a record are calendar years in which a record exists, not
years in service. What Maury does not do.
Coast Guard record current through 13 September 2026, retrieved 18 September 2026 from PSIX. Every field on this page was recorded by the Coast Guard. Records for the Research Ship class in Maury's sources begin in 1980.

Every line above is a field of the National Vessel Documentation Center's file as served by NOAA Fisheries, dated 10 September 2026, matched to this hull on its Official Number. Registered and ITC measurements are two systems and are never combined. One snapshot is held so far; documentation history begins with the next.
Radio station licence

FCC Universal Licensing System ship-station file of 6 September 2026, matched to this hull on its
US Official Number. Status and dates are the file’s own. The licensee is not read from the file and is not shown.
A lapsed licence’s MMSI is still the number the vessel transmitted under while it was valid.
A report is not offered for this hull: Its record holds only 1 of the seven kinds of material a report is built from: inspections, deficiencies, operational controls, tow-unit appearances, casualty records, dimensions and documentation. That is a statement about the record, not about the vessel. Reports.
