It was commissioned in the US Navy as USS PCE-884 in 1945, and was decommissioned after World War II.
She was then transferred and commissioned into the Philippine Naval Patrol (currently Philippine Navy) and was renamed RPS Negros Occidental (E-29) in 1948. She was carried over when the PNP was renamed the Philippine Navy in 1951, and was renamed the RPS Negros Occidental (PS-29) in the mid-1960s using a new ship classification and naming system. In June 1980, all Philippine Navy ships changed their prefixes and the ship became the BRP Negros Occidental (PS-29).[2] Her last assignment was with the Patrol Force of the Philippine Fleet.[3] She was decommissioned from the fleet on 9 December 2010 after it was found to be beyond economical repair. She is to be sold as scrap while her equipment is removed as spare for operational sisterships.[4]
Originally the ship was armed with one 3"/50-caliber dual-purpose gun, three twin Bofors 40 mm guns, four 20 mm Oerlikon guns, 1 Hedgehog depth charge projector, four depth charge projectiles (K-guns) and two depth charge tracks.[5]
The same configuration applied up until the late 1980s when the Philippine Navy removed most of her old anti-submarine weapons and systems, and added four 12.7 mm general-purpose machine guns, making her lighter and ideal for surface patrols, but losing her limited anti-submarine warfare capability.
The ship is powered by two GM 12-278A diesel engines, with a combined rating of around 2200bhp driving two propellers. The main engines can propel the 914 tons (full load) ship to a maximum speed of around 16kn.[6]
There is a slight difference between the BRP Negros Occidental as compared to some of her sister ships in the Philippine Navy, since her previous configuration was as a patrol craft escort, while the others are configured as minesweepers and patrol craft escort rescue ships.
