WW2 German Type XXIII U-Boat
There were 61 German Type XXIII U-boats commissioned during World War 2. The first XXIII, U-2321, was launched on 17 April, 1944. The development of the Type XXIII was given very high priority. To reduce development time, Dr Walter designed the new boat based on the previous Type XXII prototype.
By June 1943, the initial design was ready and construction began in parallel at several shipyards in Germany, France, Italy and German occupied USSR. The Type XXIII had an all welded hull design, and was the first submarine in the world to use a single hull design. For the power plant, the Type XXIII used the MWM RS-348 diesel engine, which was already in use as a diesel generator aboard the Type IXDs. The electric motor was the AEG GU 4463/8, which was a simplified version of the electric motors employed on the Type VIIs. Handling wise, the Type XXIII proved to be an excellent boat, which was highly maneuverable both on the surface and underwater. Crash dive time was a quick 9 seconds.
Construction of this advanced submarine faced many disruptions caused by Allied land advances, constant aerial bombings, materials and manpower shortages. Therefore, by the end of the war, out of 280 submarines ordered, only 61 had entered service.
At the end of World War 2, more than 20 of Type XXIII submarines surrendered to the Allies and only 3 remained in use after the war. (U-2326, U-2353 and U-4706)

德国U23型潜艇在第二次世界大战期间德国共有61艘U23型潜艇服役，首舰是U2321,于1944年4月17日下水。在战争后期，德国给予U23型潜艇的研发优先权，为了缩短研发的时间，沃尔特博士在U22型潜艇的基础上进行U23的研发工作。
U23潜艇的初始设计在1943才完成，接着建造工作在德、法、意和苏联占领区的造船厂进行。U23型潜艇采用焊接船体，而且是世界上第一艘采用单层船体设计的潜艇。在动力方面，该艇采用MWM RS-348型柴油引擎，该引擎在U9D型潜艇上已经作为柴电发电机使用。电动机为AEG GU4463/8型，是U7型潜艇上使用的电动机的简化型号。该舰性能非常优秀，无论是在水面还是在水底均具有极好的机动性，紧急下潜速度仅有9秒。
在U23型潜艇的建造工作上德军面对极其严重的后勤问题，主要是面对盟军在地面上的推进和持续不断的轰炸、原料和劳动力的缺乏。所以到了战争末期，原本建造280艘的计划，仅完成了61艘。
二战结束时，共有20多艘U23潜艇向盟军投降，只有U236，U2353和U4706三艘保存至战后。
