Here's a conspiracy theory for you: China probably did it and used a Yu-4a torpedo for deniability. Motive - China wants to weaken ROK economy and government.
So maybe China

Yeah but it's already been said in indicting North Korea that everyone's else subs in the region were close to home. Just as they also said NK subs and a support ship were seen leaving before and returning to port after the incident. So to change the story now would be a self-indictment of cover-up.

The Swiss has no experience in naval architecture and engineering (they don't even have a navy), and the same can be said about Singapore. Both would be poor choices for being part of or leading a naval disaster investigation team. It would be akin to asking Peru to lead and investigate the Chernobyl nuclear disaster.

Huh?

Singapore has an indigenous commercial shipbuilding industry, and its oil rig building is amongst the most established in the world. Also, we build the majority of the warships of our own navy (some are under ToT agreements, such as the RSS Formidable class stealth frigates).

As for naval disasters, we have had our share too. The most tragic being the collision of RSS Courageous with an oil tanker that resulted in 4 female sailors losing their lives.

These info are readily available on the internet, and a simple google will find it. :eek:ff

N.Korea declares combat alert over warship probe
Posted: 25 May 2010 1255 hrs

SEOUL : North Korean leader Kim Jong-Il ordered troops and civil organisations on combat alert after South Korea accused his country of sinking a warship, a defector group said Tuesday.

Seoul-based North Korea Intellectual Solidarity (NKIS) said the alert order was issued last Thursday evening, the day a multinational investigation team in Seoul announced its findings into the sinking of the Cheonan on March 26.

South Korea's National Intelligence Service said it was checking the report by the defector group.

The North denies involvement in the sinking of the Cheonan with the loss of 46 lives. It says the allegations are a plot by the United States and South Korea to spark conflict.

The communist state has threatened "all-out war" in response to any moves to punish it.

NKIS said vice minister of national defence O Kuk-Ryol announced through a fixed radio channel that Kim had ordered a combat alert.

"America and South Korea are in a frenzy for revenge against us by linking us to the Cheonan incident. This is a conspiracy by America, Japan and South Korea to isolate us and kill us," NKIS quoted the minister as saying, citing a source in the North.

The source was quoted as saying that the ruling party ordered organisations to stage mass rallies under the slogan "Revenge for revenge, war for war".

Security service members and reservists were told to wear uniform to raise their spirits, the source said.

Kim Dae-Sung, a leader of NKIS, said it was exceptional for uniforms to be worn and for Kim to order a combat alert for members of the public.

"Our sources said people are feeling insecure due to the broadcast," he told AFP. - AFP/jy

Refusal may have led to Kim getting angry and leaving ahead of schedule. Although they've said it's China refusing infrastructural aid or whatever, but it can be a coverup.
Kim ended the trip early? Can you provide a news source for this? Thanks in advance.

Well the following PDF file link is for the report.

Please, Log in or Register to view URLs content!


Its barely 4 pages long and to be frank looks more like a press release than a scientific document. (I have to prepare more simply to get small loans from the Bank).

In summary - a torpedo did it. Some bits of torpedo was found underwater that looks a bit like a NK torpedo and had a North Korean symbol painted on it. Therefore North Korea did it.

And that is pretty much it.

Nothing on metallurgy and nothing about explosive traces. A report more noticeable for what is left out rather than included.

a) This is a military interest community. b) People who come here are by definition somewhat computer literate. - Combining those two factors I think it's fair to suggest you ought to have conducted your own research rather than throwing half-baked conspiracy theories around and asking others to do your research for you.

Planeman, I am pleased for you if you have the luxury of time and other resources to plough through pages and pages of search engine results which link to endless internet news sites all showing the same tiny press releases.
I have looked for schematics for other Torpedo's which show the internal drive shaft assembly but have found more for Photon Torpedo's on the Starship Enterprise than I have current Torps in the USN ROKN inventories.

I would not be surprised if many others have the same restrictions as do I.

Mr T if you are seriously telling this forum that Intelligence releases over the last twenty years concerning the activities of countries that the West does not like, have been honest and clearly presented and in no way intended to mislead then I find you either disingenuous or seriously lacking in critical ability!

Actually I did a bit of comparison on the remnants of the torpedo that was suspected to have hit the Cheonan... I find that it look suspiciously like the Yu-3 torpedo of the Chinese. Look at the fins...

The only difference that I don't quite get it is the propellers... it seemed that the propellers on the remains are kind of larger that a typical Yu-3 torpedoes... or was it the angle.

CHT-02D is related to Chinese Yu-4a and Soviet SAET-50 types, and therefore to German T5 / G7e torpedoes.

Yu-4. Note the fin details, notched rudder etc.

Planeman.. My earlier posts are more than just that rusty torpedo. Which I have already stated originally that it's "Place of Discovery" and "time of find" is in question, not entirely whether it's a NK torpedo or not. More so was the "Metallurgy" and "Compound trace" and political relation.

It was you who made a post about that Torpedo origin as a CHT-02D. You opened that door. Even in this post You could not find a pic of CHT-02D, but state that it's "related" to the YU-4a and Soviet SAET-50 types. So how do you establish that it was a CHT-02D in the first place? That's why I asked about the shroud. Why should I conducted a research when you are the one making that cliam ? The ball was in your court. Is this you definition of "Conspiracy Theories" ?

Hate to nickpick but ... where's the two bigger counter propellers in the YU-4a ??? This torpedo was so damaged that why one would assume that it has no shroud originally.

And I take offence with your first paragraph, It simply shows how immature and somewhat "unreasonable" you are.

Sorry... not meaning to take side... but as posted on my earlier post, I do believe that the remains of the torpedo do look something like Yu-3 and not Yu-4. Please look at the photo that I have attached to it. The only difference is the big propellers.

Oh... btw... where was this remains of the torpedoes actually found. Anyone do a date test on it to see if the torpedoes was recently detonated or had been there a long time already, for I believe that area was where NK and SK clashed quite a number of time.

Plus it is possible that this torpedo was a remains from older naval clashes, and recently detonated when the ship rammed into it?

rhino.. I saw your post. But looking like this one and looking like that one, but has difference = no conclusions.

But really, I was responding especially because of what was written in the first paragraph (a & b) of Planeman. Did you notice my ??? next to the YU-4a.

It was mentioned by some news that the Torpedo was found in the area of the incident, how big the area was and where, did it follow the current like the two wreck, was not report. They were not based on any official source that I am aware of. Because there wasn't any official source.

well, the 2003 torpedo was found, but ramming part is next to impossible.

OK, I just read the rather short unnamed and unsigned investigation report. (Strange). What are they afraid of ? Would this report even have any legal standing ?

Apparently, they identified it as a CHT-02D, from NK export brochures schematics, and cliamed that it was found at the site of the incident, with nothing else backing this up.

Because all they had was...
The torpedo parts recovered at the site of the explosion by a dredging ship on May 15th, which include the 5×5 bladed contra-rotating propellers, propulsion motor and a steering section, perfectly match the schematics of the CHT-02D torpedo included in introductory brochures provided to foreign countries by North Korea for export purposes. The markings in Hangul, which reads “1번(or No. 1 in English)”, found inside the end of the propulsion section, is consistent with the marking of a previously obtained North Korean torpedo.

What was even stranger, is that they made no attempt to analysis and link the metallic debris and chemical residue from the wreckage to that torpedo. Won't this be important ? It would arouse questioning that it was of German construction and maybe not of North Korean origin.. wouldn't it ?

Further.. look at the attempted comparison to CH-02D officially by the SK.. they said it was a perfect match.

torpedo4.jpg


Perfect match ???

torpedo5.jpg


Clearly, the stabilizers in the diagram above are clearly shown IN FRONT of the separation plate.

In fact, it looked very much like the german DM2 A-4. Very very similar to a perfect match.

Guess what ! The South Korean operates German Type-214 !! And Type 214 uses DM2 A-4 !!!

N.Korea to sever all relations with S.Korea
Posted: 25 May 2010 2229 hrs

SEOUL - North Korea said Tuesday it was severing all relations with South Korea and cutting communications links in protest at claims that it had sunk one of Seoul's warships.

The North said it would expel all South Korean personnel from a jointly-run industrial estate at Kaesong north of the border, and ban South Korean ships and planes from its territorial waters and airspace.

The state Committee for the Peaceful Reunification of Korea said South Korea's claims that it had torpedoed a warship were tantamount to a declaration of war.

In a statement on the official news agency, it said it was freezing relations and abrogating a non-aggression agreement.

The statement further heightened regional tensions sparked by an official report last week, which concluded that a North Korean submarine had sunk a South Korean corvette on March 26.

Seoul on Monday announced a package of reprisals, including a halt in most trade. It plans to refer the sinking to the United Nations Security Council.

The North said it would not talk to the South again for the remainder of President Lee Myung-Bak's term of office.

The conservative leader began a five-year term in February 2008, adopting a tougher line towards the North than his liberal predecessors.

The North also vowed an "all-out counterattack" against the South's decision to resume an official cross-border propaganda campaign, including loudspeaker broadcasts.

It did not give details but had earlier threatened to open fire at the loudspeakers.

The North also said all inter-Korean issues would be handled "under a wartime law" but did not elaborate.

"There is no need to show any mercy or patience for such confrontation maniacs, sycophants and traitors and wicked warmongers as the Lee Myung-Bak group," it said.

- AFP /ls

The escalation continues. Hope it doesn't end up in a full fledged war.
