早在第二次世界大战期间,为了保证潜艇获得更好的隐蔽性和水下航行能力以便使潜艇能够发挥更大的突击作用,同时为了保证潜艇在敌人反潜兵力攻击下的安全性,世界各国的潜艇设计师绞尽了脑汁。德国海军在这方面捷足先登,最先成功地研制了潜艇通气管装置,并且在1944年建造的U-XXI型潜艇上首次装备了通气管装置。尽管德国海军最终没有来得及把装备通气管装置的U-XXI型潜艇有效地投入战争,但 As early as during the Second World War, in order to ensure submarine better concealment and underwater navigation capabilities so that the submarine can play a greater role in assault, and in order to ensure the safety of the submarine under the attack of enemy anti-submarine forces, the countries in the world Submarine designer racked his brains. The German Navy pioneered in this area and successfully developed the submarine snorkel system first and equipped it with the snorkel for the first time on the U-XXI submarine built in 1944. Although the German Navy did not finally have time to effectively put the U-XXI submarine equipped with snorkel into operation,
