She was decommissioned from the U . S . Navy and transferred to the Philippine Navy in July 1948 and renamed RPS " Cebu " ( E - 28 ) after the Philippine province of the same name . The ship is . Along with other World War II - era ships of the Philippine Navy , " Cebu " is considered as one of the oldest active fighting ships in the world today . History . Commissioned in the US Navy as USS " PCE - 881 " in 1944 , and was decommissioned after World War II . She was then transferred and commissioned into the Philippine Naval Patrol and was renamed RPS " Cebu " ( E - 28 ) in July 1948 . She was carried on to the Philippine Navy in 1950 , and between 1965 - 1966 she was renamed as RPS " Cebu " ( PS - 28 ) using a new classification system . Again in June 1980 she was renamed BRP " Cebu " ( PS - 28 ) using a new localized prefix . In 1992 the " Iloilo " underwent major overhaul , weapons and radar systems refit , and upgrade of communications gear . " Cebu " won the Philippine Navy " Ship of the Year " award for the year 2009 . She is currently assigned with the Patrol Force of the Philippine Fleet , under the jurisdiction of Naval Forces Western Mindanao . Notable Operations . Between 19 to 22 March 1958 , then RPS " Cebu " participated in the first bilateral exercise between the Philippine and US Navies dubbed " Exercise " Bulwark One " " . It took part on the 3rd phase of the exercise off the waters of Corregidor and Caballo Islands . As of 23 June 2008 , she and her onboard medical team oparticipated in the search and rescue of the MV " Princess of the Stars " of Sulpicio Lines , which capsized off the coast of San Fernando , Romblon at the height of Typhoon Fengshen on 22 June 2008 . BRP " Cebu " and BRP " Pangasinan " ( PS - 31 ) have alternately secured the Southern Sulu Sea where the Baduria Well is located . She also provides security for the West Aquarius Oil Rig . Technical details . There are slight difference between the BRP " Pangasinan " as compared to some of her sister ships in the Philippine Navy , since her previous configuration was as a patrol craft escort ( PCE ) , while the others are configured as rescue patrol craft escort ( PCER ) and minesweepers ( " Admirable " class ) ships . Armaments . Originally the ship was armed with one Mk . 26 3 " / 50 caliber dual purpose gun , three twin Mk . 1 Bofors 40 mm guns , four Mk . 10 20 mm Oerlikon guns , 1 Hedgehog depth charge projector , four depth charge projectiles ( K - guns ) and two depth charge tracks . This configuration applies before its overhaul in the early 1990s . During its overhaul and refit in 1992 , the Philippine Navy removed her old anti - submarine weapons and systems , and made some changes in the armament set - up . Some sources claim the loss of its three Bofors 40mm cannons during the 1990 - 1991 overhaul and refit period , but photos at of 2009 show the Bofors guns still present , although in singles instead of twins . Final armaments fitted to the ship are one Mk . 26 3 " / 50 - caliber gun ( fore ) , three single Bofors 40 mm cannons ( aft ) , four Mk . 10 Oerlikon 20 mm cannon s ( 2 each on bridge wings ) , and four M2 Browning 12 . 7 mm / 50 caliber machine guns ( 2 besides main bridge , 2 aft near the ship ' s end ) . This made the ship lighter and ideal for surface patrols , but losing her limited anti - submarine warfare capability . Electronics . Also during the refit the ship ' s SPS - 21D surface search radar and RCA SPN - 18 navigation radar was replaced by a Raytheon AN / SPS - 64 ( V ) 11 surface search and navigation radar system . Later modifications included the installation of long range and satellite communications systems , and GPS system standard to all Philippine Navy ships . Machinery . The ship is powered by two GM 12 - 278A diesel engines , with a combined rating of around driving two propellers . The main engines can propel the 914 tons ( full load ) ship to a maximum speed of around .
