China building Soviet designed W-class submarines according to the Australia Station Intelligence Summary dated 8 June 1957

An item reported that it was believed that two new Chinese navy W-class submarines were working-up. On 2nd April was one sighted near the entrance of the Yangtse using her own machinery. It was doubtful o f the environment of Shanghai was the right location for trials lacking sufficient depth. It was to be considered that the submarines were transferred to another base like Tsingtao, Port Arthur and Tinghai in the Chusan area after the boats were completed.(1)

1. The Russian Whiskey-class diesel-electric patrol submarines of which 5 were built in the Soviet Union and 21 by Chinese shipyards using parts delivered by the Soviet Union. The original design was developed in early 1940s to replace the S-class with the use of German technology/knowledge. The torpedo armament consisted of 6-53,3cm/21” torpedo tubes (4 bow, 2 stern).
