Does the sale represent a step in China’s possible ambitions to have a toehold in the Indian Ocean?
As previously covered by The Diplomat, Pakistan announced earlier this year that it has agreed to purchase eight modified Type 41 Yuan-class diesel-electric submarines from China. These boats will provide Islamabad with much-needed Anti-Access/Area Denial (A2/AD) capabilities against the Indian Navy in case of war. This would be especially useful in case of an Indian blockade of Pakistan’s coast and could give New Delhi grounds to pause before deploying its planned new aircraft carrier, the INS Vikrant.
A Yuan-class submarine is undoubtedly a great piece of kit. It is China’s first class of submarines to incorporate an indigenously designed- and constructed Air-Independent Propulsion system (AIP), giving it a cruise speed of 18 knots and an operational range of 8,000 nautical miles. Although the export version of the Yuan, named the S-20, does not automatically come fitted with the AIP, Pakistan has apparently been able to secure it for its subs. Furthermore, the Yuan is integrated “with advanced noise reduction techniques including anechoic tiles, passive/active noise reduction and an asymmetrical seven-blade skewed propeller.”
Combined with the AIP, this makes the Yuan-class the quietest non-nuclear sub in the PLAN. Furthermore, the Yuan has an impressive set of teeth. Aside from six tubes firing standard 553mm torpedoes, it is equipped with the YJ-8/8A Anti-Ship Cruise Missile (ASCM). While this weapon only has a maximum range of between 30-42 km, there are plans to equip the Yuans with the YJ-18 ASCM. These missiles have a reported range of 220 km and, represent a real A2/AD “force multiplier” for the Yuan. Whether Pakistan will attempt to acquire these missiles, or opt to go for another option (such as their indigenously produced Hatf VII Babur) is unknown.
The sale raises one crucial question: why is China selling Pakistan these subs? There is undoubtedly a commercial aspect to this transaction (it is unknown how much Pakistan will pay for these boats, although it is certainly in the multi-billion dollar range). However, one potential reason which is worrying analysts in New Delhi is that this represents a step in China’s possible ambitions to have a toehold in the Indian Ocean. Without opening the can of worms that is the “String of Pearls” debate, it’s worth looking at this possibility.
