Project history

USN Tang-class submarines. Agreement on the transfer was reached in 1975 to provide training for the establishment of a larger submarine force. At the time of the revolution in Iran these three ships were earmarked for transfer. Kousseh had been transferred after extensive renovation on 19.12.1978 at New London. Her acquisition was officially cancelled on 3 February 1979. She lay at New London until late 1979, with a token crew, when she was towed to Philadelphia and laid up in reserve, she was handed back to the USN in May 1979. The transfers of the other two, Tang and Wahoo, were cancelled 3.2.1979.
