8月7日上午，在英国无人驾驶深水装置“天蝎”的帮助下，几天来一直被困堪察加半岛附近海域水下190米处的俄罗斯AS-28小型潜艇终于摆脱缆索和渔网的束缚，顺利浮出水面，7名乘员全部生还。救援工作至此圆满结束。外电报道如下：The seven-man crew of a trapped Russian mini-submarine are back in port after a three-day ordeal at the bottom of the Pacific with dwindling oxygen.

Six of the seamen were taken to hospital for observation in Petropavlovsk-Kamchatsky on the eastern coast of the Pacific peninsula of Kamchatka after arriving on board a rescue ship. The other man remained on board but it was not immediately clear why, the Associated Press reported.

"Today was a very happy event. The intensive work to free our submarine at a depth of 200 meters brought results... Our comrades in the crew opened the hatch themselves," said Admiral Viktor Fyodorov, commander of Russia's Pacific Fleet, according to Reuters.

Submarine作名词表示“潜艇；潜水艇；海底生物”，作形容词表示“水下的，海底的”，相关词组有：a missile-launching submarine（导弹潜水艇）；guided-missile submarine（导弹潜艇）；a nuclear powered submarine（核潜艇）；submarine tender（潜水艇供应船）；submarine mine（水雷）等。

据悉，被困潜艇此前曾被一个海岸监测系统的水下天线所缠绕，而这根天线被一个重达60吨的锚固定在海底，救援工作面临相当难度。俄海军曾尝试用缆绳将失事潜艇“钩住”并拖离深海，但因缆绳最终从潜艇脱落而告失败。
