Program: First large US gas turbine
ships. Large frigate-like patrol ships, intended for open-ocean,
long-range operations. Diesels provide long endurance,
with gas turbines for sprint operations. Underwent major
mid-life modernizations (FRAM) 1985-1992, work included
standardizing the engineering plants, improving the
clutching systems, replacing the SPS-29 air search radar
with SPS-40 radar, and replacing the 5"/38 gun mount
and Mk.56 GFCS with the OTO Melara 76 mm compact and Mk.92
GFCS. Phalanx CIWS fitted by late 1993. The flight deck
and other aircraft facilities upgraded to handle Jay Hawk
helicopters including a telescopic hangar. URN-25 TACAN
added along with the SQR-4 and SQR-17 sonobuoy receiving
set and passive acoustic analysis systems. SBROC chaff
launchers were also fitted but not improved ESM which
have been shelved. All missiles, torpedo tubes, sonar and
ASW equipment removed in 1993-94, to focus on Coast Guard
role. Mk. 38 25 mm guns replaced the Mk. 67 20 mm guns.
Shipboard Command and Control System (SCCS) fitted to all
of the class by 1996. Surface search radar replaced by
1997-99. All Phalanx CIWS, 25 mm chain guns and radar
systems (SPS-40E 2-D air search; WLR-1H(V)5, WLR-3 early
warning, TACAN) removed prior to hot transfer to the PN
on 13 May 2011 for Php 450 million under FMS. Second ship
USCGC Dallas (WHEC 716) transferred on 2012. Refitted at
a cost of $15.15M, which included a general overhaul of
her port main diesel engine and the installation of
navigational and electronics equipment, and a two $1.8M
Mk 38 Mod 2 MGS which is designed to counter high-speed
maneuvering surface targets or slow-flying aircraft.
Currently the largest of the PN warships and PF-15 is the
PN's flagship. Third WHEC, Boutwell sold to PN as EDA,
early 2016.
Structure: Frigate-like design; powered
by diesel engines and gas turbines, and have controllable-pitch
propellers; helicopter deck and retractable hangar aft,
originally carried a 5"/38 cal gun forward. The
early gas turbine engines in these ships were inefficient.
Underwent Fleet Renovation and Modernization (FRAM) life
extensions 1985-1992 at Todd Shipyard in Seattle; work
included engineering habitability and electronics, combat
systems and communications improvements, all new armament,
rehabilitation of helicopter facilities, new radars. Have
clipper bows, twin funnels enclosing the helicopter deck,
helicopter platform aft. Mast and superstructure is
largely of Type 3456 aluminum construction, hull is of
MIL-S-16216 (HY-100 and HY-80) welded steel. Bridge

January 1943/ 29 August 1943/ 27 February 1980
Program: The USN had six classes of destroyer
escorts during WW II and the Cannon class was the longest-ranged
DE (radar picket, long hull) ship at that time. They were
constructed as ocean-going escort ships and about 70
ships of this class were constructed between 1942 and
1944. PF 11 (ex DE 169) commissioned in 29 August 1943,
USN, operated under Task Force 62, on escort duty for
transatlantic convoys, credited for sinking the German
sub U-853 in 9 May 1945 during WW II and was awarded one
battle star for WW II service. Decommissioned from USN on
10 December 1945. Served in Japan Maritime Self-Defense
Force as DE 263, Hatsuhi from 14 June 1955 to June 1975,
reverted to USN in 1975, then sold to the PN in 23
December 1978, officially commissioned in 27 February
1980 after she was towed to South Korea. Currently
serving in the West Philippine Sea near the disputed
Spratlys under the Philippine Fleet's Patrol Force.
Structure: Retired in 1993 but was
reactivated in 1995-1996, where she had a minor refit,
all ASW equipment removed including depth charge, torpedo
tubes and sonar due to lack of available spare parts..
Modernization: Towed to Korea for
modernization and overhaul, and additional guns were
added before transferred to PN. Overhauled and re-engined
in 1995. Further upgraded/ refurbished in 1998. Undergone
extensive hull and engine overhaul in 2000 during the
CARAT exercises with the assistance of USN ship USS
Salvor. Additional electronics upgrades includes Furuno

and originally formed the Hong Kong Squadron, sold to the
Philippines upon the return of Hong Kong to China in 1998
for $20 million for all three including plans and IPR
were transferred to the PN. These ships serves in the
Philippine Fleet's Patrol Force.
Structure: Among the most modern capital
surface ships of the PN. These ships are fully air-conditioned
and were designed to stay at sea during rough weather.
Bilge keels were deepened to correct rolling problems
during moderate and heavy seas. Armed with OTO Melara 76
mm Compact DP, which can fire 6 kg shells in excess of 15
kilometers, carries 450 rounds of ammunition. They carry
two additional Mk. 16 20 mm guns amidships. The ship also
carries an aft crane and two, 30-knot Avon Searaider 5.4
m semi-rigid-hull Inflatable pursuit craft, which can
carry six personnel.
Modernization: PN ordered nine units of
generators for the JCPV which were procured through
direct contracting, with Propmech Philippines as the
contractor for a project price of Php 29.868 million,
with all 9 generators delivered on June 2005. JCPV
uprating to accommodate C4I systems. Phase 1 uprating (electronic
and weapons systems) was undertaken through government-to-government
contract with the UK, with the project being awarded to
QinetiQ Ltd. of UK. Contract price is at Php 959.44
million. The project enabled the vessels to perform a
greater number and variety of missions. The vessels were
dry-docked at Keppel SY in Batangas where 97% of the
spare parts have been delivered on 21 December 2005. It
involved the installation of Ultra Electronics Command
and Control Systems and Radamec 1500 optronic director
with a daylight TV camera, thermal imaging camera and
eyesafe laser rangefinder, and its integration with the
existing refurbished 76 mm gun and the newly installed
aft 25 mm gun. The system provides fire control for
surface engagements with spotting corrections in both
line and range and has an effective secondary self-defense
anti-air capability. The Radamec 1500 can detect a small
patrol boat at ranges in excess of 12 kilometers day or
night and can perform in automatic or manual mode. It
also involved the installation and integration of new
navigation systems - Raytheon gyrocompasses, Sperry
Marine Bridge Master E Series radar, GPS system,
anemometer and EM logs. All ships have already undergone
Phase I uprating by March 2006, resulted in the optimum
utilization of precision enfilade naval gunfire to
support land forces engaged in ISO and effective on-scene
command and control platforms for SAR, anti-smuggling and
anti-drug-trafficking operations. Phase II is for the
marine engineering and propulsion upgrade, which includes
the hull modifications and repair, overhaul of the main
machinery including all electricals, control, monitoring
and auxiliary systems and crew training. It has an
approved budget of Php 354 million and the prime
contractor is F.F. Cruz Marine Corp, by 2011 all ship
have undergone Phase II Upgrade. Phase III is SLEP, which
is still under bidding. Arming with SSMs in the future
withheld due to top-weight problems.

Program: Part of the 122 ex-USN MSFs, PCEs and
PCERs, all variations to the common Admirable class hull,
designed as A/S convoy escorts and reclassified as Fleet
Minesweepers (Steel Hull). Most had been transferred to
South Vietnam, then escaped to the Philippines in 1975
during the fall of Saigon, and were subsequently sold. PS
19 (ex PCER 852) was first commissioned on 26 May 1944,
reclassified as experimental PCER in 1946, named
Brattleboro in 15 February 1956, transferred to Vietnam
in 11 July 1956 as HQ 12 Ngoc Hoi, escaped and eventually
sold the PN in 1975. PS 22 (ex PCE 895) first
commissioned on 30 October 1944, named Crestview in 15
February 1956, transferred to Vietnam in 29 November 1961
as HQ 07 Dong Da II, escaped and eventually sold to the
PN in 1975. PS 23 (ex PCER 853), served as an escort in
the Leyte invasion, as an antisubmarine picket ship in
Lingayen, as an escort during the assault on the Ryukyu
during WW II, where she was awarded two battle stars for
service. Spent time as a training ship afterwards and
renamed Amherst in 1956. Transferred to South Vietnam in
June 1970 and served as HQ 14 Van Kiep II until she
escaped to the Philippines in 2 May 1975. PS 28 (ex PCE
881) first commissioned on 31 July 1944, transferred to
the Philippines in July 1948. PS 32 (ex PCE 897) first
commissioned on 6 January 1945, transferred to the
Philippines in July 1948. These ships serves in the
Philippine Fleet's Patrol Force. PS 32 reportedly
decomissioned as of Dec 2016.
Structure: PS 19-23 were originally
fitted as rescue ships, PCER. PS 20 is of the Admirable
class MSF the rest are PCER 848 or PCE 881class. All
minesweeping and A/S equipment removed. There may be
additional variations in the armament (PS 19 has two twin
40 mm, PS 20 has two 40 mm). Number of operational units
unclear.
Modernization: All ships underwent major
refit/overhauls between 1990-1997.

Year(Laid Down/First Commissioned/Commissioned in PN):
22 June 1991/ 7 August 1993/ 6 March 2004
Program: US-built ships, based on the British
Vosper-Thoryncroft design (Province/Ramadan class missile
craft) but with light armament, different superstructure
and accommodations for SEAL team and delivery craft,
among other changes. They were intended as replacement
for seventeen ageing Sea Spectre Mk 3 for SEAL/SpecOps
transport and support, but were too large to effectively
serve in that role. Too cramped to accommodate additional
weapons and have limited endurance for their size.
Reassigned to USCG operational control, with Navy crews
and Coast Guard boarding teams, for homeland defense
missions. Designed to carry two 16 feet SEAL Combat
Rubber Raiding Craft (CRRC) and one 18 feet Rigid Hull
Inflatable Boat, but on completion carry only the RHIB.
There is a recessed platform at the stern for swimmer
debarking and embarking. Ammunition supply includes 2,000
rounds (25 mm), 2,000 rounds (12.7 mm), and 1,000
grenades (40 mm). PC 1 was commissioned as USS Cyclone,
USN in 7 August 1993, transferred to USCG in 29 February
2000, which has not utilized it, refurbished and
transferred to PN (including 2 years worth of spares) in
2004 as part of $115 million US military aid pledged by
Washington, This ship costs $30 million and is the most
modern ship in the ageing PN fleet. The primary mission
of this ship is coastal patrol, interdiction and
surveillance. This ship serves in the Philippine Fleet's
Patrol Force.
Structure: Hull constructed from BS-4360
Grade 43A steel, superstructure constructed from 5086
aluminum alloy. Main propulsion is generated by four
Paxman Valenta 16CM-16RP200M diesels, developing 3,350
bhp, driving 12.8 cm six-blade highly skewed, variable
pitch and rake, NI-AL bronze MIL-B24480A, alloy 1
amendment 3 (nickel-aluminum-bronze alloy) propellers,
with pitch ratio of 1.465 at 0.7 radius and designed by
USN NSWCCD(Code 544 drawing number P-5237B). Four
Reintjes WVS-2232 reduction gearbox, with a reduction
ratio: 2.025:1. Fuel capacity is 47,772 liters (12,620
gallons). Oil capacity is 568 liters (150 gallons). Total
air conditioning plants production, 83.33 kW. They can
refuel at sea, using astern fueling rigs. Fully
operational at Sea State 3 with cruising speed of 25
knots, with 50% fuel capacity. Ship can survive up to Sea
State 5. Maximum ship endurance at 10 days. Electricity
supplied by two Caterpillar Model 3306 DIT Series B,
rating 150 kW @ 1,800 rpm. Reverse osmosis desalinators,
having a 1,514 liters (400 gallons) capacity per day.
Fresh water capacity is 4,701 liters (1,242 gallons).
Equipped with Vosper fin stabilization system and a stern
wedge to improve trim at high speeds. Kevlar armor is
fitted to the command space. The Sperry Vision 2100M
combat system employs the navigational radars and the
Sperry Voyage Management System integrated navigation and
control system as a combat data suite. Navigation systems
include GPS and Loran receivers. Radio gear includes LST-5C
SATCOM/line of sight UHF transceiver, A5 Spectra VHF
radio, ICM120 Marine Band radio, and RF 5000 HF, VRC-92A
VHF, and VRC-83(V)2 VHF/UHF transceivers. AN/SAT-2A
infrared signaling systems are fitted, and the Marconi
Vistar stabilized FLIR sensor with integral low light
level television camera is mounted on the mast. Have IFF
transponder but no interrogation capability, and
optionally available. Wesmar side-scanning hull-mounted
HF sonar with the sonar transducer is retracted within
the hull at speeds above 14 knts.
Modernization: Refitted by Bollinger
Machine Shop and SY for the PN in 2005 and had its stern
extended by nine feet to accommodate a deck ramp - which
extends down to below the water line, for a 20 feet Rigid
Hull Inflatable Boat (RHIB). PN plans to uprate main
weapon with a heavier caliber.
