Islamabad is planning to buy six submarines outright with options of joint development of conventional submarines with China, The Express Tribune reported.
The newspaper did not mention the class of submarines being sought by Pakistan saying merely that Islamabad wanted advanced under-sea vessels with air independent propulsion (AIP) system, which would give them capabilities to stay submerged longer and operate noiselessly.
The Defence Ministry has asked the federal Cabinet to approve the purchase of Chinese submarines to counter "emerging threats" faced by Pakistan, the paper said.
Pakistan has a total of five active diesel electric submarines plus 3 midget submarines.
