감사원이 10일 발표한 천안함 감사결과 해군이 사고발생 수일 전 북한 잠수정의 특이동향을 파악했다는 등의 새로운 사실들이 속속 드러났다.

사고 직후 천안함이 침몰원인을 ’어뢰피격으로 판단된다’고 보고한 사실이 공식 확인됐고, 북으로 향하는 미상의 물체에 사격을 가한 속초함도 ’북한의 신형 반잠수정으로 판단된다’고 보고했던 것으로 밝혀졌다.

제2함대사령부(이하 2함대)는 이런 보고 내용을 무시하거나 내용을 가공해서 상급부대에 보고했다는 지적을 받았다.

감사원은 군이 잠수정을 이용한 공격 가능성을 예상했고 사고 직전에 북한 잠수정의 이상 동향을 파악하고도 적절히 대응하지 않았다고 지적했다.

연평해전과 대청해전 등 서해 NLL 인근에서 북한과 수차례 교전을 했는데도 대표적인 비대칭전력으로 꼽히는 북한 잠수함에 대한 대비태세가 소홀했던 것이다.

해군은 천안함 사건발생 수일 전부터 북한 잠수정 관련 정보도 전달받았지만, 적절한 대응조치를 취하지 않았다.

그때 적절한 조치를 취했다면 용사 46명의 목숨을 앗아간 천안함 사건은 발생하지 않을 수도 있었을 것이라는 지적이 나오고 있다.

민군 합동조사단의 한 고위 관계자는 지난달 20일 조사결과 발표 당시 북한 잠수정이 기지를 이탈했다는 첩보를 접수했지만 설마 남쪽으로 내려와 우리 군함을 공격할지는 몰랐다는 취지의 발언을 해 빈축을 사기도 했다.

한국국방연구원(KIDA)의 백승주 박사는 “지난해 초부터 북한이 도발할 것이라는 예상이 많았다”면서 “당시 첩보를 제대로 검증했느냐 혹은 검증이 필요한 첩보였는지가 중요하다”고 말했다.

2함대가 사고 당일 천안함으로부터 침몰원인이 ’어뢰피격으로 판단된다’는 보고를 받고도 이런 사실을 합참이나 해군작전사령부 등 상급기관에 제대로 보고하지 않은 것도 공식 확인됐다.

사고 직후 미상의 물체에 사격을 가한 속초함이 ’북의 신형 반잠수정으로 판단된다’고 보고했으나 2함대가 속초함의 보고와 달리 상부에 ’새떼’로 보고하도록 지시한 사실도 드러났다.

군이 초기대응 과정에서 사고발생 시각을 조작한 사실도 밝혀졌다.

합참은 해군 작전사령부로부터 사건발생시각이 9시15분(실제는 9시22분)이라고 보고받았지만 이를 9시45분으로 수정해 장관 등에게 보고했다.

감사원은 합참이 발생시각을 임의로 수정한 것은 초동 대처 지연에 따른 비난을 의식한 행동으로 해석했다.

합참은 사고 당일 폭발음 청취 등 외부공격에 의한 사고 가능성도 보고받았지만 이를 삭제한 채 외부에 발표했다.

KIDA의 차두현 박사는 “상황 대처에만 급급했던 것으로 보인다”며 “여러 개의 상충 정보가 오면 어떤 상황인지 평가할 수 있어야 하는데 그렇게 하지 못한 것 같다”고 말했다.

감사원은 이날 기자회견에서 사고시점에 천안함을 촬영한 열상감시장비(TOD) 동영상이 있느냐는 질문에 “없다”고 밝혔다.

천안함 침몰 사건이 발생했던 당시 한국과 미국 양국 군이 사건 발생장소에서 75마일(120㎞) 떨어진 곳에서 합동으로 대잠수함 훈련을 하고 있었다고 AP통신이 5일(현지시간) 보도했다.

이 통신은 한.미 양국군의 대잠수함 훈련은 3월 25일 저녁 10시에 시작돼 다음날(26일) 저녁 9시에 끝났다고 주한미군 대변인인 제인 크라이튼 대령이 말했다고 전했다.

The U.S.-South Korean anti-sub exercise began at 10 p.m. March 25 and ended at 9 p.m. the next day, Army Col. Jane Crichton, a spokeswoman for U.S. forces in Korea, told The Associated Press. The exercise was terminated because of the blast aboard the Cheonan.

이와 관련, 통신은 이 훈련은 한.미 연례 키리졸브 훈련의 훈련의 일환이었다고 전했다.

우리 해군 관계자는 이 보도에 대해 “천안함 침몰 당시 한.미 양국이 충남 태안반도 서쪽 격비도 이남 해상에서 훈련 중이었던 것은 맞지만, 사건 당일 대잠훈련이 있었는지는 확인이 안된다”면서 “사건이 발생한 해역과는 120㎞ 이상 떨어져 있어 사건을 인지하기는 어려웠다”고 말했다.

AP Enterprise: Sub attack came near drill

WASHINGTON — The night a torpedo-armed North Korean submarine allegedly sank a South Korean patrol ship, the U.S. and South Korea were engaged in joint anti-submarine warfare exercises just 75 miles away, military officials told The Associated Press.

The blast that sank the Cheonan, the worst South Korean military disaster since the 1950-53 Korean War, showed how impoverished nations such as North Korea can still inflict heavy casualties on far better equipped and trained forces, even those backed by the might of the U.S. military.

Defense Secretary Robert Gates said Friday that plans for more joint U.S.-South Korea anti-submarine exercises, announced after the sinking of the Cheonan, are on hold awaiting United Nations action on the incident.

In part, Gates said, there is concern about instigating another rash act by the North Koreans.

Two months after the sinking, U.S. officials for the first time disclosed details of the joint naval exercise held the same day as the attack on the Cheonan. Forty-six South Korean sailors died on the warship, which was not involved in the exercise but on routine patrol near disputed waters.

Military officials said the drill could not have detected Pyongyang's sub. Officials and defense experts said that a minisub would have been difficult for even a nearby ship to track in shallow coastal waters.

"A small submarine in shallow waters is very hard to detect," said John Pike, director of GlobalSecurity.com, a military think tank.

What surprised experts was that a 130-ton minisub could without warning take down a warship nine or 10 times its size, a power mismatch called asymmetric warfare.

"To us, stealth denotes the latest technology — billions of dollars in research and development in armaments," said John Park, a Korea expert at the U.S. Institute of Peace. "The North Korean version of stealth is old-school diesel-battery operated subs that evade modern detection methods."

An South Korean-led investigation into the sinking concluded last month that the evidence overwhelmingly pointed to the North, but Pyongyang has steadfastly denied any involvement.

South Korea and its allies, meanwhile, have called the attack a shocking provocation, even for the regime of North Korea's eccentric Communist dictator Kim Jong Il.

Western experts say there are still questions about exactly what happened that night off Baengnyeong island.

One U.S. official privately said the sinking may not have been an intentional attack at all, but the act of a rogue commander, an accident or an exercise gone wrong. He spoke on condition of anonymity because he was not authorized to discuss the incident publicly.

That would be for North Korea to explain, said the official, but so far Pyongyang's only response has been denial and indignation. A statement run by state media threatened war in response to any attempt to punish the North.

"Because of the South Korean war-loving, mad puppets and American invaders, the North and South relationship is being driven to a catastrophe," Choi Yong Rim, a high-ranking North Korean Party official, told a Pyongyang rally last week.

U.S. and South Korean forces can easily monitor the movements of North Korean submarines when they operate on the surface.

Underwater, tracking submarines relies on active or passive sonar. Passive sonar uses microphones to listen for the sounds of sub operations. Active sonar emits sounds and listens for the echoes as they bounce off of submerged objects.

The Cheonan was operating its active sonar at the time, South Korea's Navy officer Kim Young-kyu, a spokesman for the U.N. Command in Korea, told The Associated Press. It wasn't clear why the ship didn't detect the sub.

After the blast, a South Korean commander dispatched a patrol boat to look for subs.

But officials said the vessel couldn't locate any, perhaps because of the weather, currents and rough conditions that chilly March night. Those factors, as well as the rocks and ledges in shallow water, can all affect the reliability of sonar, experts say.

Sonar technology has traditionally been designed to operate in deep waters and used for convoy protection rather than coastal defense.

"There's a lot of equipment that works pretty well against big submarines out in the deep ocean, but doesn't work so well against small submarines in shallow water," analyst Pike said. "We've got the same concern with Iran and the Persian Gulf."

North Korea is believed to have a fleet of 70 submarines, including some 50 that are small but still capable of carrying a torpedo.

The night before the Cheonan sank, two U.S. destroyers and other ships maneuvered and practiced tracking while a South Korean navy submarine played the role of target.

The U.S.-South Korean anti-sub exercise began at 10 p.m. March 25 and ended at 9 p.m. the next day, Army Col. Jane Crichton, a spokeswoman for U.S. forces in Korea, told The Associated Press. The exercise was terminated because of the blast aboard the Cheonan.

The submarine drill was part of annual U.S.-Korea war games called Key Resolve/Foal Eagle, which are intended to keep forces ready in the event another major war erupts on the Korean Peninsula.

Key Resolve was an 11-day computer simulation started early in the month. Foal Eagle followed at midmonth and included live firing by U.S. Marines, aerial attack drills, urban combat and other training as well as the anti-submarine warfare drill.

As the exercises got under way, Army Gen. Walter Sharp, commander of U.S. forces in Korea, said it was practice for "all the threats that North Korea can throw at us."

North Korea claimed the exercises amounted to attack preparations and demanded they be canceled.

The North's military said that it would bolster its nuclear capability and break off dialogue with the U.S. in response to the drills. But Pyongyang rails at Key Resolve/Foal Eagle every year, one U.S. official said.

Seoul has taken the sinking of the Cheonan as a wake-up call, and vowed to review and strengthen its defenses. The U.S. is planning two major naval exercises with South Korea in the coming weeks on top of the more than dozen of various types that it holds each year.
