About BRP Gregorio Velasquez

BRP Gregorio Velasquez is Philippine Navy's first oceanographic research vessel. It was built by the United States Navy as USNS Melville (T-AGOR-14) for university support of Navy programs. The ship was operated as the research vessel R/V Melville by the Scripps Institution of Oceanography for oceanographic research. As the R/V Melville, it was the oldest active vessel in the academic research fleet, collectively known as the University-National Oceanographic Laboratory System (UNOLS) (UNOLS). The US Government confirmed on 17 November 2015 that the Melville was to be transferred to the Philippine Navy as Excess Defense Articles (EDA)s. The vessel was officially transferred to the Philippines on 28 April 2016 and was commissioned into active service at the same time with the Philippine Navy.
