U.S. official: N. Korea torpedo likely sunk S. Korean warship
A North Korean torpedo attack was the most likely cause for the sinking of a South Korean warship last month, according to a U.S. military official.
The United States believes the ship was sunk by the blast of an underwater explosion, but that the explosive device itself did not come in contact with the hull of the South Korean ship, the official said. This is the same conclusion expressed by South Korean military officials.
The U.S. Navy has an investigative team assisting the South Koreans.
The U.S. official declined to be named because of the sensitivity of the matter and due to the fact neither South Korea or the United States has publicly discussed any potential response.
The 1,200 ton corvette Cheonan was split in half by the blast on March 26.
Forty of Cheonan's 104 crew members have now been confirmed dead, and six
more are also believed dead, though they are still listed as missing.
Fifty eight others were rescued before the vessel sank.
The Korea Times is reporting a Chinese developed Type EO-3G torpedo may have been the weapon used. It is said to have the homing capability to hit a ship after tracking the vessel's screws acoustically. U.S. Navy warships are equipped with sophisticated sensors and acoustic technology aimed at tracking such threats.

ＭＫ-48魚雷が駆逐艦に命中し沈没する様子
今回の韓国哨戒艦と同じような壊れ方をしていますねぇ～
最近のは艦艇の横に直接命中させるタイプよりも
艦艇の真下にもぐりこみ水中で爆発させ、その破壊力をもって艦艇をへし折るタイプ
それで最近の艦艇は二重底にして艦艇の強度をもたせようとしているのか・・・
次世代のズムウォルト級ミサイル駆逐艦も二重底採用してる。
次世代型を見てみると
搭載砲の口径拡大が目に付く
62口径155mm単装砲 2基
70口径57mm単装砲（CIWS）2基
これもミサイルや魚雷の単価（数億円）が余りにも高くてコストパフォーマンスが悪いため砲が見直されている
日本の護衛艦も、いずれはこのようにステルス化および口径拡大化するのだろう。
