BRP Gregorio del Pilar (PF-15) is a Philippine Navy frigate and the lead ship of her class. She was the second ship of the Philippine Navy to be named after Gregorio del Pilar, a Filipino revolutionary general known for his role at the Battle of Tirad Pass.
From 1967-2011 the ship was a United States Coast Guard high-endurance Hamilton-class cutter named the USCGC Hamilton (WHEC-715). The U.S. decommissioned the cutter on March 28, 2011 and the Philippines acquired it under the Excess Defense Articles and the Foreign Assistance Act and is one of two ex-US Coast Guard Hamilton-class cutters to serve the Philippine Navy.
Construction and design
BRP Gregorio del Pilar (PF-15) was launched on December 18, 1965 at Avondale Shipyards near New Orleans, Louisiana as USCGC Hamilton (WHEC-715) and was named for Alexander Hamilton the first United States Secretary of the Treasury and founder of the United States Revenue Cutter Service. Hamilton was commissioned March 18, 1967.
The ship is designed with a high level of habitability and provides fairly comfortable accommodations, including air conditioning. Gregorio del Pilar is the first Philippine military vessel to employ the now common shipboard application of aircraft gas turbine jet engines with the use of controllable pitch propellers and is equipped with two 18,000 horsepower (13,000 kW) Pratt & Whitney gas turbines that can propel the ship at speeds up to 28 knots (52 km/h). Gregorio del Pilar also has two 3,500 horsepower (2,600 kW) Fairbanks-Morse diesel engines, capable of driving the ship economically at 17 knots (31 km/h) for up to 14,400 nautical miles (26,700 km) without refueling. A retractable/rotatable bow propulsion unit provides maneuverability in tight situations. The ship has a flight deck and hangar capable of handling helicopters. Currently, a BO-105 light surveillance helicopter is assigned to the ship, to be replaced with an AW-109 Power ASW/SAR helicopter bought from Italy.
The ship was armed with a Mk.75 Oto Melara 76 mm Compact main gun, two Mk.38 M242 Bushmaster 25 mm chain gun at midships, and a Phalanx CIWS system aft. The CIWS and chain guns were removed by the US Coast Guard prior to its turn-over to the Philippine Navy. Only the Mk.75 gun remains.
It was also reported that the Philippine Navy will be getting sophisticated radar system capable of detecting and tracking surface threats, a Harpoon anti-ship missile system, and torpedo decoy systems. This would be purchased from the United States possibly under a government-to-government deal.
United States Coast Guard (1967-2011)
In 1988, Hamilton completed a three-year fleet renovation and modernization that provided the ship with modern weapons and electronics systems. All spaces and machinery were also completely overhauled and refurbished. The new technology enables Hamilton to operate seamlessly with the United States Navy.
Hamilton has served a variety of missions with distinction. During a 1969-70 deployment to Vietnam, Hamilton interdicted weapons smugglers and fired more than 4,600 rounds of gunfire in support of U.S. and Vietnamese troops ashore. From 1965-1975, Hamilton served on Atlantic Ocean Stations, collecting valuable oceanographic data and conducting frequent search and rescue missions. Hamilton also directed the interdictions of over 21,000 Haitian migrants throughout the Caribbean during Operation Able Manner. In 1994, Hamilton received the Coast Guard Meritorious Unit Commendation for rescuing 135 Haitians from the sea after their sailboat capsized and sank. In 1996, Hamilton transited the Panama Canal and served as the command and control platform for Operation Frontier Shield, a multi-agency effort to curtail the influx of narcotics into the United States. Hamilton intercepted 14 drug-laden vessels carrying more than 115 tons of contraband worth 200 million dollars. In 1999, Hamilton seized over 2,700 kilograms of cocaine bound for the U.S. in the Eastern Pacific Ocean. Hamilton frequently patrols the Bering Sea off the Alaskan coast at the Maritime Boundary Line (MBL) which separates the Russian and the United States' Exclusive Economic Zones (EEZ). Hamilton's presence on the MBL deters foreign fishing vessels from fishing in the U.S. EEZ.
In March 2007, Hamilton assisted the Sherman in the largest recorded maritime drug bust in history. The two vessels intercepted the Panamanian-flagged fishing vessel Gatun in international waters and were able to recover 20 metric tons of cocaine, with an estimated street value of $600 million retail. The seizure was the largest drug bust in US history and the largest interdiction at sea.
Proposal to decommission USCGC Hamilton from the US Coast Guard was made for fiscal year 2011 budget, and the Philippines sent a formal letter of interest for its purchase. USCGC Hamilton was decommissioned on March 28, 2011 and transferred to the Philippine Navy as an excess defense article under the Foreign Assistance Act. The Philippines sent a team to conduct a thorough inspection of the ship on November 2010.
The US Coast Guard removed some of the ship’s equipment before its transfer to the Philippine Navy and plans to use those equipment as spare parts for the other US Coast Guard ships. Among those that were removed are the AN/SPS-40 air surface search radar, Phalanx CIWS, and two Mk.38 M242 Bushmaster 25 mm chain guns. In return, the US Coast Guard began procuring and installing the safe-to-sail navigation equipment, radar systems and additional electronics that the Philippines requested as part of its transfer support case. The Philippine Navy plans to install a 25mm chain gun, six mounted 50-caliber guns and two 20mm cannons as replacement for the equipment removed.
The ship's transfer cost was pegged at Php450 million, while operation costs for two years was estimated at Php120 million. Funding came from Philippines' Department of Energy, considering that the vessel is projected to be deployed to secure oil platform and exploration activities in the Western and Southern Philippines.
Training for the crew started on January 2011, when the US Coast Guard provided 10 weeks of combined dockside and underway training on USCGC Boutwell (WHEC-719) for the ship's prospective commanding officer, executive officer and crew.
Its maiden voyage included a port visit to Hawaii and docking at Alameda, California to finish the remaining work, with around 13 separate contracting actions. Gregorio del Pilar conducted a test at the coast of California to measure the crew’s capabilities and the ship’s seaworthiness. Gregorio del Pilar made a port visit at Joint Base Pearl Harbor-Hickam which was the first time that a Philippine vessel docked at Pearl Harbor. She arrived on the Philippines on August 17, 2011 after port visit in Guam. Gregorio del Pilar arrived in Manila on August 21, 2011. The arrival ceremony was held on August 23, 2011 and minor improvements were done the following days.
Gregorio del Pilar was formally commissioned by the Philippine Navy on December 14, 2011 at Pier 13, Manila South Harbor. President Benigno Aquino III's elder sister, Maria Elena “Ballsy” Cruz was the principal sponsor of the ship.
President Aquino hopes that this, his first major military acquisition, will be a symbol of his administration's intention to strengthen and modernize the Philippine Navy and the Armed Forces, and to defend its territory and Exclusive Economic Zone (EEZ) in the South China Sea.
Notable Operational deployments
On 27 July 2011, the BRP Gregorio del Pilar arrived at Joint Base Pearl Harbor-Hickam for a scheduled port visit. She took on supplies and fuel, and held a reception hosted by the Philippine Consulate in Honolulu and the Philippine Celebrations Coordinating Committee of Hawaii. The crew also visited the USS Arizona Memorial. It also marks the first time a Philippine naval vessel pulled into Pearl Harbor.
On 22 August 2011, the United States Embassy in Manila posted on their Facebook account photos indicating that BRP Gregorio del Pilar had an in-stride training with USS Fitzgerald (DDG-62) on their transit to Guam, which may have started around 4 August 2011.
On 14 to 16 of August 2012, the Naval Forces Northern Luzon (NFNL) conducted a small-scale Naval Exercise code-named SAGEX 02-12 at the waters of South China Sea. BRP Gregorio del Pilar together with BRP Rajah Humabon and BRP Liberato Picar participated under Naval Task Force (NTF) 11. The exercise includes patrol, simulated tracking of targets and interdiction and capped by live firing exercises.
The ship conducted an offshore visit at Lingayen, Pangasinan during the city's "Pistay Dayat 2013" ("Feast of the Sea 2013"), with an open house tour and rescue exhibition exercises performed by the crew.
From 27 June to 2 July 2013, the BRP Gregorio del Pilar participated in joint naval maneuvers during Cooperation Afloat Readiness and Training 2013 Philippines (CARAT 2013 Philippines) with other Philippine and United States naval and coast guard ships. The at-sea phase was conducted on June 27 off the waters midway from Zambales province and Panatag (Scarborough) Shoal.
