SKorea launches new missile boat class

Can Canada buy some? We need a new Offshore Patrol Vessel, and these will fit the requirements to a t, except for the ice-resistant requirements.

The US should build a vessel about three times as big...say 1,500 tons. Arm it similarly, but add sonar, some ASW capability (torps) and an eight cell Mk-41 with 32 ESSM for AAW and call that the LCS. If they wanted a single helo and/or UAVs, make it 2,000 tons and add a hangar.

Cheaper, as well armed, and something that could be built in numbers now. But that's just my opinion. The current LCS is in trouble.

These ROKN missile patrol and gun patrol boats are nice and fit their need very aptly.

Our requirements require long endurance, decent sea worthiness, minimally armed, and maybe a helicopter deck. I would enlarge the design up to 650 tons, and have a rear helicopter deck capable of handling a small helo for short periods at a time. I would also thicken the hull so that it is minimally ice resistant.

The US requirements are for longer endurance as well...at 1500 to 2000 tons, they could achieve that, add the ASW weaponry and sonar, add the helo hangar, and add the AAW missiles and the senors and radars and electroinics associated with them.

Those would be nice corvettes and could then be used well for the LCS mission IMHO. We could build 40-50 of those a lot cheaper than the current LCS design.

Then, build a USCG version that is a gunboat and helo only version...20-30 of those as well.

Oh well, it is the ROKN that is building these and I believe they will build 28 of each of their own variants. Kudos to them.

The Gumdoksuri (PKX) clas patrol ship is being built to replace the 30+ year old Chamsuri (PKM) class patrol ships.

If you look at the older Chamsuri class boats, many of them were equipped with 40mm Bofors gun in aft position. For whatever the reason, the South Korean navy decided to retain the same system.

Here's the South Korean Navy's version on the 2002 sea battle:


I suspect the South Koran Navy decided to do a mix of missile & gun-only boats for operational flexibility in sensitive areas. For example if a Japanese survey ship comes too close to Dokdo, they'd probably send a lesser-armed patrol ship over to chase the intruder off. Sending missile-armed Corvettes might needlessly escalate the confrontation.

Examples include the "cod wars" of Europe, first between UK and Denmark, then between UK and Iceland. The 2 sides played bumper cars with their ships and manned the guns as last resort.

Canada doesn't need such heavily-armed vessels, does it? These ships are designed to deal with a threat Canada isn't facing as far as I can see.

You'd be better off getting something like a modified HMS Clyde of the sort we might be using for the "C3 class" of the S2C2 project.

Well, we need something faster than the Kingston class MCDV's, while being cheaper to operate and smaller than the Halifax class frigates, while having real teeth compared to the Kingston's and the new Orca class training and patrol vessels.

Re the PKA, seems on a par with Japan's highly capable Hyabusa missile boats, though probably better sensors traded for worse AAA. Though the 40mm are good secondary antiship at close quaters which seems to be the norm in the DPRK clashes with previously started with warnings and end in guns at point blank. The DPRK have 85mm and 57mm on most boats which is formidible if you get within range in a boat as the S Korans found out in the infamous incident that prompted this design. At the 7km mark this design would easily outgun anything DPRK has (except maybe something new?) - even their frigates which have 100mm.

If S Korea buys Davide AAA round, combined with their sensor suite, it'd be quite good AAA as well, not that DPRK has any air threat worth mentioning.

Actually, back to the twin 40mm AAA, unless DPRK gets some new SSM other than the KN-01, then the Bofors is probably adequate.

that 40mm is indeed odd choise...all other similar sized big missile boats have atleast Goalkeeper or even SAM fit...then again DPRK is the sole advisor or South Korean littorial areas, and their current silkworm/Styx generation of SSMs can be dealed with ECM like in 1973 Yom Kibbur war.

I think the 40mm is for stop any suspected civilian ship if needed. When they want to make sure the ship understand the situation without damage it too much. Several rounds of 76mm will probabily sink the ship and bring a political trouble.

Or you can fire a few rounds across someone's bow or bridge with the 76mm and that will get their attention quick...

HMS Clyde is easily smaller.
What is faster?
What is "real teeth" and why do they need it?
Do you want something that is only good for local patrolling, or something that has a high range?
