原文：

 To find something which is small, quiet, submerged and doesn't wish to be found, Northumberland sent sound waves through the depths as she tested both her hull-mounted and towed-array sonar systems–and also switched to silent running to passively listen for the ultra-quiet submarine.

 That tests not just the skills of the sonar operators in the operations room, but the entire ship's company, who have to minimize all noise aboard–even down to removing shoes.

 And the frigate pulled out the ace up her sleeve in the form of her Merlin Mk2 helicopter. Mohawk Flight from 814 Naval Air Squadron at Culdrose used her sonobuoys (listening devices dropped in the ocean) and her 'dipping' sonar, lowered beneath the Merlin, to locate and successfully track the Uredd's movements throughout the exercise–and conducted simulated attacks to defend Northumberland.

中譯：

 為了找到這艘既小又安靜且不想被發現的水下潛艦，「諾森伯蘭號」在測試艦載聲納及拖曳陣列聲納系統時，向深海處發送聲波，並切換到無聲運轉模式，以被動偵聽這艘超靜音潛艦。

 這不僅考驗操作室內聲納操作員的技術，也考驗著全艦人員，他們必須將艦上所有聲音降到最低，甚至做到要脫掉鞋子的地步。

 接著，這艘巡防艦亮出王牌利器─梅林Mk2型反潛直升機。這架來自英國卡德羅斯空軍基地第814海航中隊的莫霍克反潛直升機，運用其聲納浮標（投入海中的偵聽設備），以及從該直升機下方垂降下的懸吊式聲納，找出「烏瑞德號」，於演習全程成功追蹤其動態，並進行模擬攻擊作為，以防衛「諾森伯蘭號」。（第４篇／共9篇）
