The Pohang corvette acquisition
« 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 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.

Material condition of the boat beyond the capabilities of prospective bidders?
