She was previously known as BRP "Dagupan City" (LC-551) prior to a classification change implemented by the Philippine Navy starting April 2016  The 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. Both ships of its class were purchased brand-new by the Philippine government through the FMS program of the United States. Since its commissioning, both ships of its class were rigorously used in military and peacetime operations, and has been joining joint military exercises with foreign navies as well. Presently it is assigned with the Service Force of the Philippine Fleet. Originally named as the BRP "Cagayan de Oro City", she was commissioned with the Philippine Navy as BRP "Dagupan City".

The ship is powered by two General Motors-EMD 16-645EZ6 diesel engines with a combined power of around 5,800 hp driving two propellers. The main engines can propel the 1,400 ton (4,265 tons full load) ship at a maximum speed of around . At a sustained speed of , it range is at around . As an amphibious transport, it is fairly armed for defensive purposes, and carries four 7.62mm general purpose machine guns at the front side decks, and two Oerlikon 20 mm cannons near its two LCVPs. 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. The ship does not require external cranes or port facilities, and even in only four feet of water under full load, the ship is still able to land. This capability expands the choice of landing locations, and at the same time reduces the potential enemy impact on the logistics support operations.
