Frigate

BRP Rajah Humabon (PF-11) (ex-USN USS Atherton DE-169)


Datu Kalantiaw Class (USN Cannon Class)
"Cannon-class destroyer escort"

The Cannon class destroyer escorts were built primarily for ocean Anti-Submarine Warfare escort service during World War II. The lead ship, USS Cannon (DE-99) was commissioned on 26 September 1943 at Wilmington, Delaware. The class was also known as the DET type from their Diesel Electric Tandem drive[1]. Of the 116 ships ordered 44 were cancelled and 6 commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting the vulnerable cargo ships.
BRP Rajah Humabon (PF-11) of the Philippine Navy, formerly the USS Atherton (DE-169) remains as the only confirmed commissioned ship of this class as of 2010.







USS Atherton (DE-169), a Cannon-class destroyer escort, was the only ship of the United States Navy to be named for Lt. (jg) John McDougal Atherton, who died when the USS Meredith sank near Guadalcanal during World War II.

Atherton (DE-169) was laid down on 14 January 1943 at Newark, New Jersey, by the Federal Drydock & Shipbuilding Co.; launched on 27 May 1943; sponsored by Mrs. Cornelia A. Atherton, the mother of Lt. (jg.) Atherton; completed at the Norfolk Navy Yard; and commissioned there on 29 August 1943, Lt. Comdr. Paul L. Mansell, Jr., USNR, in command.

Service history

Atherton began shakedown in September. During this time, conducted exercises in Chesapeake Bay and made two cruises to Bermuda. On 13 November, she got underway for Puerto Rico. Upon her arrival there, the destroyer escort assumed anti-submarine warfare (ASW) patrol duties in waters between St. Croix, Virgin Islands, and the Anegada Passage. On 24 November, she attacked a submarine contact, but observed no evidence of damage. The ship was relieved three days later and returned to Norfolk on 30 November. There, she began making daily cruises in Chesapeake Bay to train prospective crew members for destroyer escorts. Atherton left Norfolk on 11 December to escort a convoy bound for the Panama Canal but was back in Hampton Roads on 27 December.
From January 1944 to May 1945, Atherton operated under the control of Task Force 62 on escort duty for transatlantic convoys. She escorted convoys from Norfolk and New York City to various ports in the Mediterranean. These ports included Casablanca, Morocco; Bizerte, Tunisia; and Oran, Algeria. Atherton periodically reported to the Boston Navy Yard for overhaul. On 9 May 1945, while en route from New York to Boston, Atherton encountered a U-boat. After four depth charge attacks, pieces of broken wood, cork, mattresses, and an oil slick broke the surface. Atherton, in conjunction with Moberly (PF-63), was later credited with destroying the German submarine U-853.

On 28 May, Atherton sailed for Guantanamo Bay, Cuba. She arrived on 1 June and held a week of exercises with Escort Division 13 before sailing on 6 June for the Pacific. Proceeding via the Panama Canal and San Diego, Atherton arrived at Pearl Harbor on 29 June. There, the ship underwent a tender availability and carried out a series of exercises before getting underway on 15 July for the Marianas. She reached Saipan on 26 July and conducted antisubmarine patrols off Saipan. On 5 August, she got underway for Ulithi, where she operated on picket station until 18 August. Between 19 August and 16 September, Atherton made two round-trip voyages escorting convoys to Okinawa. She was then assigned to rescue station duties out of Saipan which lasted through the end of the war.

On 1 November, Atherton headed back toward the United States. After stops at Pearl Harbor and San Diego, she transited the Panama Canal and arrived at Jacksonville, Florida, in December. On 10 December 1945, she was decommissioned and placed in reserve at Green Cove Springs, Florida. On 14 June 1955, Atherton was transferred to Japan; and, her name was struck from the Navy list.

Awards
Atherton was awarded one battle star for her World War II service. Crew members of the USS Atherton DE 169 received a bronze star in the American Theater ribbon for their action in the sinking of the last German submarine of World War II in American Waters. The battle took place shortly after the U-853 had torpoedoed the Boston Collier "Black Point" at 5:40PM, May 5, 1945 (just a few hours before VE Day). The Atherton tracked down the U-853 just eight miles off Block Island, RI sinking her in just 100 feet of water. The next day divers were sent down, confirming the only sinking of a sub with the newly developed "Hedge Hogs."

Transfer and sale


Hatsuhi circa 1967

Japan
USS Atherton was transferred to Japan in 1955 and commissioned in the Japan Maritime Self-Defense Force as Hatsuhi (DE-263). After 20 years in service, she was retired in 1975 and was reverted back to the United States Navy.


Rajah Humabon circa 2009

Philippines
Atherton was transferred to Philippines in 1978. She was commissioned in Philippine Navy service in 1980 after a refit in South Korea as BRP Rajah Humabon (PS-7. She was reclassified as patrol frigate and changed the hull number to (PF-6). She was decommissioned in 1993, but was recommissioned in 1995 with a different hull number (PF-11). She is still in active service with the Philippine Navy as of 2010.

Corvettes

Jacinto Class (RN Peacock Class)


The Jacinto class is a ship class of three patrol corvettes currently in service with the Philippine Navy. The ships formerly served in the Royal Navy's Hong Kong Squadron as Peacock class patrol vessels until 1997.
The three vessels have undergone weapon, electronics, propulsion and hull upgrades in Philippine Navy service, greatly increasing their capabilities.

History

Launched as a series of five patrol vessels, the Peacock class were originally part of the Hong Kong Squadron of the Royal Navy. The ships were built by Hall Russell in the United Kingdom and were commissioned into Royal Navy service from 1983 to 1984. The class was designed specifically for patrol duties in Hong Kong waters. As well as "flying the flag" and providing a constant British naval presence in the region, they could also undertake a number of different roles including seamanship, navigation and gunnery training. In addition, they performed search-and-rescue duties for which they had facilities to carry divers (including a decompression chamber) and equipment to recover vessels and aircraft. They also worked with the Marine Department of the Hong Kong Police and with Customs & Excise in order to prevent the constant flow of illegal immigrants, narcotics and electronic equipment into the Colony.

Three of these ships - HMS Peacock (P239), HMS Plover (P240), and HMS Starling (P241) - were sold to the Philippines as a sign of goodwill, and were officially turned over to the Philippine Navy on 1 August 1997 when the sovereignty of Hong Kong was transferred from the United Kingdom to the People's Republic of China.

Technical details

The ships under this class are characterized by a low freeboard, an Oto Melara 76 mm gun turret located forward, a large single funnel stack amidships, and a crane and two rigid-hulled inflatable boats (RHIB) aft.
The Oto Melara 76 mm Compact DP (Dual Purpose) gun is the primary weapon and is mounted in a turret forward of the bridge. It has a range of up to 10 nautical miles (20 km) and can be used against ships, aircraft or ground targets. It is remotely controlled from within the Combat Information Center by the gunnery officer and has no crew within the turret itself. The gun can fire 80 rounds in 60 seconds from its ready magazine, and the ships can carry a total of 450 rounds each.

The secondary weapon (located at the stern) is a M242 Bushmaster 25 mm cannon in an MSI Defense System mount. This weapon is integrated with the 76 mm primary weapon via an Ultra Electronics Command and Control System and a Radamec 1500 Electro-Optical Tracking/Fire Control System. This new system was installed as part of Phase 1 of the Philippine Navy JCPV upgrade program.
In addition, the ships of this class also carry two 7.62 mm general purpose machine guns on the bridge wings, and two Oerlikon 20 mm cannons amidships.

The ships are powered by two APE-Crossley SEMT-Pielstick diesels (14,188 bhp combined) driving two three-bladed propellers. It has a drop down loiter engine with a shrouded prop of 181 bhp (135 kW) used to keep station and save fuel. The main engines can propel the 664 ton (712 tons full load) ship at over 28 knots (52 km/h), with a sustained speed of 25 knots (46 km/h). Its range is 2,500 nautical miles (4,630 km) at 17 knots (31 km/h).

These corvettes were specifically designed for Asian service, having air-conditioned crew spaces and have been designed to stay at sea during typhoons and other strong weather anomalies common to Asian seas. The ships were modified soon after entering the Royal Navy service with deeper bilge keels to alleviate a propensity to roll during moderate and heavy seas.

Upgrades
Aside from the new M242 Bushmaster 25 mm cannon and upgrade of its command & control and fire control systems as part of the ship's Phase 1 upgrade, the Philippine Navy also installed a new Raytheon gyro compass, Sperry Marine Naval BridgeMaster E Series Surface Search Radar, GPS, anemometer, and EM logs. These were integrated with the ship's existing systems. The Phase 1 upgrade was completed in 2005.

Phase 2 is the Marine Engineering Upgrade Program, which includes the repair and remediation of the hull, overhaul and improvement of the main propulsion including control and monitoring systems, electrical plant, auxiliary systems, outfitting and hull furnishings and training the crew in the operation and maintenance of the new plant.

Phase 3 (still in bidding) is a Service Life Extension Program (SLEP).
There are plans to add an anti-ship missile system to this class, but due to top-weight problems, it would have to be a lightweight system such as Sea Skua. However, no missiles have been ordered to date

Corvettes

Rizal Class (USN Auk Class)


The Rizal class is a ship class of two patrol corvettes currently in service of the Philippine Navy, and are currently its largest class of corvettes. These ships were formerly used by the US Navy as Auk class minesweepers. Under the Philippine Navy, the two vessels have undergone upgrades and modification, and were categorized as corvettes.

History
The Auk class of naval ships were Allied minesweepers serving with the United States Navy and the British Royal Navy during the Second World War. In total, there were a recorded 95 Auk class minesweepers under Allied command during that time.

Thirty-two minesweepers were ordered by the US (as BAM-1 to 32) intending them to be supplied to the Royal Navy under Lend-lease but 12 were retained for USN use and given names and "AM" hull classification prefix. Those transferred were given "J" pennant number prefixs and formed the Catherine class
Eleven minesweepers of the Auk class were lost in World War II; only one (USS Skill) was sunk — by U-593.
Out of the reserved US Navy units, two were transferred to the Philippines as part of the US Military Assistance Program, these were USS Murrelet (renamed BRP Rizal) in 1965, and USS Vigilance (renamed BRP Quezon) in 1967.

Both ships were stricken in 1994, but were overhauled with assistance from Hatch & Kirk, Inc., and returned to service in 1995-1996. Recent upgrades includes a satellite radio dish for communications.As of 2008, both ships are still on the active roster of the Philippine Navy, and are assigned with the Patrol Force.

With 40 years of active duty with the Philippine Navy, both have been involved local and international crisis, exercises, and incidents

Technical details
Although fairly armed for her size, her weapon systems are manually operated and are of World War II origin.
The two Mk24 3"/50 caliber guns, the ships' primary weapons, have a range of up to 14,600 yards (13,400 m) yards and are also capable of anti-aircraft warfare.

In addition to the above mentioned guns, she also carries a total of two twin Mk1 Bofors 40 mm anti-aircraft guns, two twin Mk4 20 mm Oerlikon cannons, and four 50 caliber machine guns.

The ship is powered by two EMD 16-645E7 diesel engines with a combined power of around 5,800 bhp (4,300 kW) driving two propellers. The main engines can propel the 1,250 ton (full load) ship at a maximum speed of around 18 knots (33 km/h). It has a maximum range of 5,000 nautical miles (9,260 km) at a speed of 12 knots (22 km/h).

Corvettes

Rizal Class (USN Auk Class)


The Miguel Malvar class is a ship class of patrol corvettes of the Philippine Navy, and are currently its oldest class of corvettes. These ships were formerly used by the US Navy as Admirable-class minesweepers, and PCE-842-class and PCE(R)-848-class patrol craft, which were both based on the Admirable-class hull. In the Philippine Navy, the vessels have undergone upgrades and modifications, and have been re-categorized as corvettes.

One ship, the former USN USS Quest (AM-281) was supposedly a member of this class but was converted into a non-combatant Presidential Yacht by the Philippine Navy in 1948 as the RPS Pag-asa (APO-21) (later on renamed as RPS Santa Maria, and as RPS/BRP Mount Samat)

History
The PCE class of naval ships were served with the United States Navy during the Second World War.
Out of the reserved US Navy units, six were transferred to the Philippines as part of the US Military Assistance Program (PS-28 to PS-33), while five where former South Vietnamese Navy units that escaped to the Philippines in 1975.
With 40 years of active duty with the Philippine Navy, ships of this class have been involved local and international crisis, exercises, and incidents.

Technical details
Originally the ship was armed with one 3"/50 caliber dual purpose gun, two to six Bofors 40 mm guns, 1 Hedgehog depth charge projector, four depth charge projectiles (K-guns) and two depth charge tracks.

The same configuration applies up until the late 1980s when the Philippine Navy removed most of its old anti-submarine weapons and systems, and three 20 mm Oerlikon guns and four 12.7 mm general purpose machine guns were placed, making it lighter and ideal for surface patrols, but losing its limited anti-submarine warfare capability.

The ship is originally powered by two Cooper Bessemer GSB-8 diesel engines, but was replaced by two GM 12-567ATL diesel engines similar to her sister ships, with a combined rating of around 1,710 bhp (1,280 kW). This was then again replaced in the mid 1990s with two GM 12-278A diesels with a combined rating of around 2,200 bhp (1,600 kW) driving two propellers. The main engines can propel the 914 tons (full load) ship to a maximum speed of around 16 knots (30 km/h).

Patrol Craft

Mariano Alvarez Class (USN Cyclone Class)
BRP Mariano Alvarez (PS-3 (ex-USN USS Cyclone PC-1)

The BRP Mariano Alvarez (PS-3 is the lone ship of the same class of coastal patrol ships in service with the Philippine Navy. Historically, she is the lead ship of the Cyclone class (a class of US Navy patrol ships) prior to being transferred to the Philippine Navy (thereby making the PN the only navy other than the US Navy to operate a Cyclone-class ship). Today she is considered as the newest active fighting ship in the Philippine Navy.

Launched as the first of fourteen ships of Cyclone class patrol ships, the primary mission of the Cyclone was to serve as a platform for conducting maritime special operations, including interdiction, escort, noncombatant evacuation, reconnaissance, operational deception, intelligence collection, and tactical swimmer operations. Her small size, stealthy construction and high speed were tailored to performing long-range Special Operations Forces (SOF) insertion and extraction as well as other SOF support duties as needed.


History
As good a design as it is, the Cyclone had barely gone into service in the mid-1990s when the Special Operations Command rejected them as too big for commando missions, and the regular surface Navy dismissed them as too small for any of its missions. The Navy began looking for ways to phase out the Cyclone and her sister ships, so on 28 February, 2000, the Cyclone was decommissioned and stricken from the Navy list.

It was then transferred to the United States Coast Guard the next day, being re-commissioned as the USCGC Cyclone (WPC 1). The Coast Guard lacked an effective vessel sized between its 110' patrol cutter and the 210' Medium Endurance Cutter, so there was considerable interest in Cyclone at first. However, her high operating costs were prohibitive and thus she sat largely inactive.

Cyclone was eventually sold under FMS to the Philippine Navy on 8 March, 2004, as part of a US military aid package to the Philippines, in an effort to bolster interdiction and counterterrorism capabilities. She was rechristened BRP Mariano Alvarez (PS 3, in honor of a revolutionary general in the Philippine war of independence against Spain.She is currently assigned to the Patrol Force of the Philippine Fleet

Performance
The ship's operational capabilities were designed to meet the unique requirements of its Special Warfare missions. Operationally, the Cyclone was capable of accelerating from stop to 35 knots (65 km/h) in under three minutes, then move from full ahead to 15 knots (28 km/h) astern in 60 seconds. In high-speed, hard-over turns, the ship barely heeled as the automatic stabilizers engaged.

Weapons
Originally armed with two Mk38 25 mm chain guns fore and aft, several pintle mounts for attaching .50 caliber machine guns or Mk19 grenade launchers, and a position for launching Stinger shoulder-fired SAMs (although this was removed when the ships was transferred to the Philippine Navy), the Cyclone, along with others of her class, were upgraded early on by replacing the after Mk38 mount with the new Mk96 platform. The Mk96 combines both a 25 mm chain gun and a 40 mm grenade launcher on a single stabilized platform. The Mk96 features an electro-optical fire control system with 27x zoom, infrared and low-light modes, a laser rangefinder, and an array of environmental sensors, which feed data into the ballistics computer to produce an accurate firing solution even while maneuvering at high speed. The computer can also interface with Stinger SAMs (which are currently unavailable). The Navy was positive about the performance of the Mk96 and briefly considered up-gunning the 25 mm Bushmaster cannon to a 30 mm or even 35 mm cannon, but due to the high price this never came to pass.

Sensors
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. The radar intercept equipment was developed for use on helicopters. Has a Sperry Marine automated Integrated Bridge System (IBS).Each Mk 52 decoy rocket launcher carries 12 ready-service rounds, and 15 more rockets per launcher are carried in adjacent lockers. The decoy launchers in one unit are to be replaced by two 12-round, 102-mm ML Aviation Super Barricade rocket launchers mounted on superstructure platforms for trials. Ammunition supply includes 2,000 rounds 25-mm, 2,000 rounds .50 cal, 2,000 rounds 7.62-mm, and 1,000 40-mm grenades.
Navigation systems include Global Positioning System 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, although it may be added later. The sonar transducer is retracted within the hull at speeds above 14 kts.

Structure
The hull was constructed using BS-4360 Grade 43A steel, the superstructure was constructed using 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.

Upgrades
Refitted by Bollinger Machine Shop and Shipyard for the Philippine Navy 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). The Philippine Navy plans to upgrade the main weapon with a heavier caliber.
