NOAAS Discoverer is an American oceanographic research vessel scheduled to enter commissioned service in the National Oceanic and Atmospheric Administration (NOAA) in 2026. She is under construction, with completion anticipated in 2026. She is the second NOAA ship to bear the name Discoverer.




Design



Discoverer and her sister ship NOAAS Oceanographer represent an effort by the National Oceanic and Atmospheric Administration (NOAA) to recapitalize its aging fleet. The ships are built to commercial standards, and NOAA describes them as "state-of-the-art" and designed to support a wide variety of scientific missions, with a capability of conducting general oceanographic research and exploration as well as more specific studies of marine life, the oceanic climate, and ocean ecosystems. The ships can perform scientific missions in shallow coastal waters and over the continental shelf, as well as ocean survey and data collection worldwide. The ships are equipped to launch work boats, perform maintenance on buoys and moorings, deploy scientific instruments to collect weather and water-column data, and conduct seafloor mapping surveys.
To help meet NOAA's goal of reducing its carbon footprint, each ship incorporates high-efficiency diesel engines that comply with strict Environmental Protection Agency (EPA) Tier IV final emissions requirements, stack-gas emission controls, and other technologies which NOAA estimates will save 15,000 US gallons (57,000 L; 12,000 imp gal) of diesel fuel per year for each ship and result in an estimated reduction of approximately 5,700 short tons (5,200 t) of carbon dioxide. Each ship has a crew of 20 and accommodation for up to 28 embarked scientists.




Construction


NOAA acquired Discoverer and Oceanographer through an agreement with the United States Navy's Naval Sea Systems Command. On 31 December 2020, the U.S. Navy awarded a US$178,082,877 contract to Thoma-Sea Marine Constructors of Houma, Louisiana, to design and build the two ships.
Discoverer′s construction began with a ceremony at the Thoma-Sea Marine Constructors shipyard in Houma on 28 October 2022. During the ceremony, the initials of the ship's sponsor, Second Gentleman of the United States Douglas C. Emhoff, husband of Vice President Kamala Harris, were welded onto a steel plate that was to be incorporated into the ship's structure during construction.




Operational career


Plans call for Discoverer to enter service in NOAA's fleet in 2026. Her home port will be Newport, Rhode Island.
