There have been a series of training accidents involving second-generation ships. For example, during the 1996 Hankuang exercises, because of faulty communication between air and sea, rapid-fire CIWS guns on one Chengkung class frigate accidentally shot down a target-towing plane, killing all four crew members. On another occasion, due to carelessness, a Chengkung class frigate suffered serious damage while docking.
海軍二代兵力建立後，時有傳出演習意外事件，例如民國八十四年漢光演習時成功級軍艦曾因海空聯繫不良，艦上方陣快砲誤中拖靶機，機上四人全部罹難。
