Title: The Pohang corvette acquisition
Post by: adroth on September 29, 2016, 11:30:29 PM
Nothing confirms the impending transfer or an EDA asset like a PhilGEPS invitation seeking bidders for contracts to refurbish the acquisition target. The long reported, and mysterious, Pohang class corvette from South Korea has not only been confirmed in this manner, it has also been identified. See the relevant PhilGEPS invite (http://www.philgeps.gov.ph/GEPSNONPILOT/Tender/SplashBidNoticeAbstractUI.aspx?menuIndex=3&refID=3622062&DirectFrom=OpenOpp&Type=agency&BusCatID=0) below:

Rumors of a potential Pohang class transfer first surfaced in 2011. However a formal announcement of the transfer was not made till 2014. Both events were discussed on the Timawa forum on this thread.

The ROKS Mokpo (PCC-759) was the fourth ship in the Pohang Class to be built. Produced by Daewoo SB & Hvy Mach., Okpo in 1988. It is the last of the class to be optimized for Anti-Surface Warfare (ASuW) and armed with Exocet Surface-to-Surface Missiles (SSM). Subsequent members of the class geared towards for Anti-Submarine Warfare (ASW) missions.

In Korean service, it was armed with 2 MM38 Exocet launchers, a single 76mm Oto Melara DP gun, 2 twin Emerlec AA guns, and 2 triple 324mm ASW torpedo tubes. Its air search capability stemmed from a Raytheon SPS-64 radar, and for ASW functionality, it was equipped with a Thales PHS-32 hull mounted sonar. As of writing it is unclear how much of this equipment would be retained in the transfer.

Unlike the Hamilton class WHECs whose gas turbines were of an older variant that were used exclusively by the class, the Pohang is powered by the significantly more commercially successful General Electric LM-2500 which is the gold standard for marine gas turbines. For low-consumption transit, the Mokpo relies on its two MTU 12V956 diesel engines.

great find, sir A.! persistent whispers also say that this will be the first, and that 2 others- another donation and another in friendship prices- will be negotiated on soon. would be nice to know if there is going to be some upgrades for them in the near future.

Its air search capability stemmed from a Raytheon SPS-64 radar...

just a slight correction @chief, the sps64 is actually the navigation/surface-search* set... the air search capability actually stems from the wm28 CAS (combined antenna system, aka the "egg") which contains a spoiled/cut paraboloid search antenna in the lower half which allows rudimentary 4-elevation band air surveillance out to ~40 km (or ~60 km for upgraded versions which Signaal - now Thales - previously offered)... while the upper half of the CAS houses the dish tracker fire-control antenna... the wm28 is actually what was the basis for (and license built in the US) as the mk92... so at least there's some commonality with what's on the PN's WHECs...

data referenced from:
     sps64, wm28 specs - N.Friedman, "World Naval Weapon Systems"
     mokpo equipment fit - E.Wertheim , "Combat Fleets of the World"

(*as an aside, the wide vertical beamwidth of 22-25 degrees used by the sps64 antenna will result in RF radiation into low-elevation angles but the set itself is designed mainly for processing of surface returns)

This is another Pohang related ITB. Both are with Closed status.

ROKS Chungju Flight III ASW is offered in place of ROKS Mokpo.

After conducting of the Joint Visual Inspection by the Philippine Navy, spearheaded by the Offshore Patrol Force's commanding officer himself, the Philippine Navy decided to finally accept the offer made by the South Korean government to transfer the Pohang-class Flight III anti-submarine corvette. It appears that only 1 ship was offered by the South Korean government, while the other decommissioned Flight III ships will be going to 2 other countries, among them is neighbouring Vietnam.

The ship is expected to be assigned with the Offshore Combat Force (OCF) of the Philippine Fleet.

The ship, reported to be the former ROKS Chungju (PCC-762), was built by Korea Tacoma Shipyard, was commissioned with the Republic of Korea Navy in 1987, and was decommissioned in December 2016. Based on this, the ship is around 30 years old, or at least 20 years younger than the Hamilton-class cutters acquired by the Philippine Navy from the US Coast Guard.

It is considered a Flight III sub-class of the Pohang-class combat corvette, which is configured for anti-submarine warfare. It is equipped with two Oto Melara 76mm Compact naval guns, two Breda twin 40mm/70 naval guns, two Mk. 32 triple torpedo tubes, and two Mk.9 depth charge racks. It was previously fitted with Harpoon anti-ship missile launchers, and while they are not included in the transfer, the ship won't need too much adjustments for launchers to be re-installed again.

The ship's sensors suite include Raytheon AN/SPS-64 radar, Signaal WM-28 Fire Control system, and a Raytheon AN/SQS-58 hull mounted sonar.

Well, if its already here, it will add to the "frustrations of when" its Combat Systems Upgrade project will be implemented, just like the DPCFs  ;D

PH set to acquire Pohang-class corvette from South Korea (http://www.rappler.com/nation/168121-philippine-navy-pohang-class-corvette-south-korea)
Published 3:50 PM, April 27, 2017
Updated 3:50 PM, April 27, 2017

MANILA, Philippines The Philippines is set to acquire one of the decommissioned Pohang-class corvettes of the Republic of Korea Navy, likely to be delivered within the year, to boost the country's capability to patrol its vast waters.

"We have sent a letter to the government of South Korea expressing our intent to acquire one Pohang-class corvette. We are hoping to receive the vessel within the year," said Arsenio Andolong, chief of the Department of National Defense Public Affairs Office.

The Pohang-class corvettes are patrol gunboat ships. Andolong said the type and configuration of the ship that the Philippines will acquire have yet to be determined.

"It will definitely enhance our capability to patrol our waters and perform counter terrorism missions," Andolong said.

The Philippines will pay a token fee of $100 for the vessel, but it will have to shoulder the refurbishing of the decommisioned vessel. It's an arrangement similar to the country's acquisition of 3 former US Coast Guard ships. The refurbishing cost is not yet known.

"The transfer will be in the form of a donation. However, we will pay a token fee of $100," Andolong said.

DND to acquire SK 'Pohang' ASW corvette for USD100 (http://www.pna.gov.ph/index.php/articles/983146)
April 27, 2017

MANILA, April 27 --- The Department of National of National (DND) will be acquiring a "Pohang" Flight III anti-submarine corvette from South Korea for just USD100.

<snipped>

"We have sent a letter to the Government of South Korea expressing our intent to acquire one Pohang class corvette. We are hoping to receive the vessel within the year (no specific date yet)," DND public affairs chief Arsenio Andolong said in a message to the Philippine News Agency Thursday.

"The transfer will be in the form of a donation, however, we will pay a token fee of USD100. The corvette will still undergo refurbishment, the cost of which we will shoulder," he added.

However, Andolong has no information on whether the transfer will include the ship's weapon and sensor suites and exact cost of the refurbishment.

But he added that the ship will definitely boost the Philippine Navy's capability to patrol the country's territorial waters aside from helping in the fight against piracy and terrorism.

MANILA, April 27 --- The Department of National of National (DND) will be acquiring a "Pohang" Flight III anti-submarine corvette from South Korea for just USD100.

This is possible as South Korea is now in the process of retiring the above-mentioned ship from its inventory.

"We have sent a letter to the Government of South Korea expressing our intent to acquire one Pohang class corvette. We are hoping to receive the vessel within the year (no specific date yet)," DND public affairs chief Arsenio Andolong said in a message to the Philippine News Agency Thursday.

But he added that the ship will definitely boost the Philippine Navy's capability to patrol the country's territorial waters aside from helping in the fight against piracy and terrorism.

"Pohang" are class of general purpose corvettes operated by the South Korean Navy.

Around 24 were built during the late Cold War and post-Cold War period. Out of this number, 18 are still in commissioned as of this posting.

These ships are armed with a variety of anti-sub, anti-ship, and anti-air weapons with their accompanying sensor gear and are capable of running to speeds up to 32 knots. (Priam F. Nepomuceno/PNA)

A pohang class corvette is roughly the size of the PF11 in length ) 4.7 meters difference. Weight is almost the same also Pohang ( 1200/1300 tons ) BRP Humabon (1390 tons - standard )
