For example, when the ROC navy acquired two subs from the US in the 1970s for training purposes, the Americans deliberately sealed off the torpedo tubes to insure that the subs could only be used as the "enemy ships" for ASW training, but could not be used offensively.
例如目前被我當作反潛訓練用的海獅、海豹潛艦，七○年代自美國手中接艦時，美國刻意將艦上所有魚雷管剪斷線路，使其無法發射魚雷，意思是這艦艇售予台灣，只能當作假想敵訓練用，而非用來攻擊。
