The '''BRP ''Francisco Dagohoy'' (PF-10)'''<ref>This article assumes that the authoritative ''Jane{{'}}s Fighting Ships 1980-1981'', p. 370, is correct about ''Francisco Dagohoy''{{'}}s lineage (i.e., that she was the former [[USS Castle Rock (AVP-35)|USS ''Castle Rock'' (AVP-35)]], [[USCGC Castle Rock (WAVP-383)|USCGC ''Castle Rock'' (WAVP-383/WHEC-383)]], and [[RVNS Tran Binh Trong (HQ-05)|RVNS ''Tran Binh Trong'' (HQ-05)]]). The United States Coast Guard Historian{{'}}s Office (see http://www.uscg.mil/history/webcutters/CastleRock1948.asp) and ''Conway{{'}}s All the World{{'}}s Fighting Ships 1947-1982 Part II: The Warsaw Pact and Non-Aligned Nations'', p. 356, agree with ''Jane{{'}}s'' that ''Francisco Dagohoy'' was the former ''Castle Rock'' and ''Tran Binh Trong''. However, extensive confusion exists on on the Web. NavSource.org in its entry for ''Castle Rock'' (see http://www.navsource.org/archives/09/43/4335.htm) also agrees with ''Jane{{'}}s'' that ''Tran Binh Trong'' (HQ-05) became ''Francisco Dagohoy'' but in its entry for [[USS Chincoteague (AVP-24)|USS ''Chincoteague'' (AVP-24)]] and [[USCGC Chincoteague (WAVP-375)|USCGC ''Chincoteague'' (WAVP-375/WHEC-375)]] (see http://www.navsource.org/archives/09/43/4324.htm) also states that it was ''Chincoteague'' that became ''Tran Binh Trong'' and ''Francisco Dagohoy''. Meanwhile, the Inventory of VNN{{'}}s Battle Ships Part 1 (see Part 1 at http://www.vnafmamn.com/VNNavy_inventory.html) claims that ''Tran Binh Trong'' was the former ''Chincoteague'' and became yet another Philippine Navy ship, [[BRP Andres Bonifacio (PF-7)|''Andres Bonifacio'' (PR-7)]], and in its Part 2 (see Part 2 at http://www.vnafmamn.com/VNNavy_inventory2.html) says that ''Castle Rock'' became an entirely different South Vietnamese ship, [[RVNS Ngo Kuyen (HQ-17)|RVNS ''Ngo Kuyen'' (HQ-17)]], before becoming ''Francisco Dagohoy''. The ''Dictionary of American Naval Fighting Ships'' entries for ''Castle Rock'' (see http://www.history.navy.mil/danfs/c4/castle_rock.htm) and ''Chincoteague'' (see http://www.history.navy.mil/danfs/c8/chincoteague.htm) apparently were written before the ships were transferred to South Vietnam or the Philippines and have not been updated, and therefore make no mention at all of their South Vietnamese or Philippine Navy service.</ref> on 5 April 1976. She was decommissioned in June 1985,<ref>Per NavSource Online at http://www.navsource.org/archives/09/43/4335.htm.</ref> was a [[frigate]] of the [[Philippine Navy]] that served from 1979 to 1985. She was one of six ex-[[United States Navy]] [[Barnegat class seaplane tender|''Barnegat''-class]] small [[seaplane tender]]s and ex-[[United States Coast Guard]] [[Casco class cutter|''Casco''-class]] [[high endurance cutter]]s received from the United States after the [[Vietnam War]], two of which were cannibalized for spare parts without entering service. She her other three sister ships were the largest Philippine Navy ships of their time.

==History==
===Construction and United States Navy service 1944-1946===

{{main|USS Castle Rock (AVP-35)}}

''Francisco Dagohoy'' was built in the [[United States]] by [[Lake Washington Shipyard]] at [[Houghton, Washington|Houghton]], [[Washington (state)|Washington]], as the [[United States Navy]] [[Barnegat class seaplane tender|''Barnegat''-class]] [[seaplane tender]] [[USS Castle Rock (AVP-35)|USS ''Castle Rock'' (AVP-35)]]. [[Ship commissioning|Commissioned]] in October 1944, ''Castle Rock'' served in the [[Central Pacific Area|Central Pacific]] during and after [[World War II]]. She was [[Ship decommissioning|decommissioned]] in June 1946 and placed in reserve.

===United States Coast Guard service 1949-1971===
{{main|USCGC Castle Rock (WAVP-383)}}

In 1948, the U.S. Navy loaned ''Castle Rock'' to the [[United States Coast Guard]], which commissioned her that year as the [[United States Coast Guard Cutter|cutter]] [[USCGC Castle Rock (WAVP-383)|USCGC ''Castle Rock'' (WAVP-383)]]. She was later reclassified as a [[high endurance cutter]] and redesignated WHEC-383. While in Coast Guard service, her primary duty was to patrol [[Ocean Weather Station|ocean stations]], reporting [[weather]] data and engaging in [[search-and-rescue]] and [[Law enforcement agency|law-enforcement]] operations. She also performed combat duty in the [[Vietnam War]] for a few months in 1971.

==Republic of Vietnam Navy service 1971-1975==
{{main|RVNS Tran Binh Trong (HQ-05)}}

''Castle Rock'' was transferred to [[South Vietnam]] on 21 December 1971 and was commissioned into the [[Republic of Vietnam Navy]] as the [[frigate]] [[RVNS Tran Binh Trong (HQ-05)|RVNS ''Tran Binh Trong'' (HQ-05)]]. She fought in the [[Battle of the Paracel Islands]] in 1974.

When South Vietnam collapsed at the end of the Vietnam War in late April 1975, ''Tran Binh Trong'' fled to [[Subic Bay]] in the [[Philippines]], packed with South Vietnamese [[refugee]]s. On 22 May 1975 and 23 May 1975, a U.S. Coast Guard team inspected ''Tran Binh Trong'' and five of her sister ships, which also had fled to the Philippines in April 1975. One of the inspectors noted: "These vessels brought in several hundred refugees and are generally rat-infested. They are in a filthy, deplorable condition. Below decks generally would compare with a garbage scow."<ref>This quote, from the U.S. Coast Guard Historian's Office at http://www.uscg.mil/history/webcutters/McCulloch_1946.pdf, is unattributed.</ref>

==Acquisition by the Philippines==
After ''Tran Binh Trong'' had been cleaned and repaired, the United States formally transferred her to the [[Republic of the Philippines]] on 5 April 1976.
She was commissioned into the [[Philippine Navy]] as frigate RPS, later BRP, ''Francisco Dagohoy''. She served in the Philippine Navy until she was decommissioned in June 1985.<ref name="Navsource Castle Rock">''NavSource Online: Service Ship Photo Archive''. [http://www.navsource.org/archives/09/43/4335.htm USS ''Castle Rock'' (AVP-35)].</ref>

==Technical details==
The single Mark 12 [[5"/38 caliber gun|5-inch/38-caliber]] (127-[[millimeter]]) guns was ''Francisco Dagohoy''{{'}}s primary weapon. It was mounted in a Mark 30 Mod 0 enclosed base ring and had a range of up to {{convert|18200|yd|m}} yards. The gun was a dual-purpose type, capable of both [[antisurface]] and [[antiaircraft|antiair]] warfare. She also carried two twin Mark 1 [[Bofors]] 40&nbsp;mm anti-aircraft guns, four Markk 4 single 20&nbsp;mm [[Oerlikon 20 mm cannon|Oerlikon]] cannons, and four .50-[[caliber]] (12.7-mm) general-purpose [[machine gun]]s.<ref name="DLSU NROTC">DLSU N-ROTC Office. [http://www.dlsu.edu.ph/offices/sps/rotc/pdf/ms2/namingPNships.pdf ''Naming and Code Designation of PN Vessels''].</ref>

[[Hatch and Kirk, Inc.]] added a [[helicopter]] deck aft in 1979.<ref>''Philippine Naval Forces News Bulletin [http://www.geocities.com/pentagon/barracks/7248/navy2.htm Naval News Bulletin # 1].</ref> Although the ship had no capability to house or service visiting helicopters, the helicopter deck could accommodate one [[MBB Bo 105]]C helicopter, used by the Philippine Navy for utility, scout, and maritime patrol purposes.

''Francico Dagohoy'' was powered by two [[Fairbanks-Morse]] 38D [[diesel engine]]s with a combined power of around 6,200 [[brake horsepower]] (4.63 [[megawatt]]s), driving two [[propeller]]s. The main engines could propel the 1,766-[[displacement (ship)|displacement]]-[[ton]] (standard load) ship at a maximum speed of around {{convert|18|kn|km/h|0}}. She had a maximum range of {{convert|8000|nmi|km|-1}} at an economical speed of {{convert|15.6|kn|km/h|0}}.<ref name="DLSU NROTC"/>

The Philippine Navy made plans to upgrade the entire ship class with new radar systems and the BGM-84 [[Boeing Harpoon|Harpoon]] long-range anti-ship [[cruise missile]], but this did not materialize due to the worsening political and economic crisis in the Philippines in the mid-1980s.<ref>''Harpoon Database Encyclopedia [http://www.harpoondatabases.com/Encyclopedia/Entry1757.aspx AVP-10 Barnegat class]</ref>

==Philippine Navy service==

''Francisco Dagohoy'' was commissiond on 23 June 1979,<ref name="ReferenceA"/> three years later than her three sister ships. She was decommissioned in June 1985, and some of her usable parts were used to maintain her sister ship [[BRP Andres Bonifacio (PF-7)|BRP ''Andres Bonifacio'' (PF-7)]].{{Citation needed|date=July 2008}}

''Francisco Dagohoy'' was discarded in March 1993 and probably scrapped.
