 The next submarine project will see KS&EW jointly involved with Chinese company CSOC (China Shipbuilding & Offshore International Co. Ltd.) in the design and construction of 8 submarines equipped with air-independent propulsion (AIP).These will be designed to Pakistani specifications and four will be built at a CSOC shipyard in China, while four will be constructed by KS&EW.It is believed that little upgrading of facilities is required because much of the current infrastructure meets the requirements.
