About RV Knorr
RV Knorr was a research vessel formerly owned by the U.S. Navy and operated by the Woods Hole Oceanographic Institution for the U.S. research community in coordination with and as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet. On March 14, 2016, Knorr was officially transferred to the Mexican Navy and renamed Rio Tecolutla. She was replaced at Woods Hole by the RV Neil Armstrong. Knorr is best known as the ship that supported researchers as they discovered the wreck of the RMS Titanic in 1985. R/V Knorr (AGOR-15) has traveled more than a million miles—the rough equivalent of two round trips to the Moon or forty trips around the Earth. Her sister ship is the RV Melville.
