BRP Dagupan City (LS-551) is the second and last ship of two Bacolod City-class logistics support vessel, and is based on a helicopter capable variant of the US Army Frank S. Besson class.

She was previously known as BRP Dagupan City (LC-551) prior to a classification change implemented by the Philippine Navy starting April 2016 BRP Dagupan City was built by Halter/Moss Point Marine of Escatawpa, Mississippi in the United States and was commissioned into Philippine Navy in 1994.

Recent photos show the words "BRP Cagayan de Oro City" still embossed at the rear end of the ship's steel surface.

The prime mission of the ship is the direct transport and discharge of liquid and dry cargo to shallow terminal areas, remote under-developed coastlines and on inland waterways.

This capability expands the choice of landing locations, and at the same time reduces the potential enemy impact on the logistics support operations.
