A Comprehensive Look at Pakistan's Newly Inducted Hangor-Class Submarine Fleet
Summary
Pakistan Navy officially commissioned its first Hangor-class air-independent propulsion (AIP) submarine, PNS/M Hangor, at a ceremony in Sanya, China, attended by President Asif Ali Zardari and Chief of Naval Staff Admiral Naveed Ashraf, marking the culmination of a decade-long acquisition program. The program originally stemmed from a failed negotiation with German shipbuilder HDW for Type 214 submarines, which led Pakistan to pivot to China's CSOC in 2011, ultimately resulting in a government-approved purchase of eight submarines in 2015 valued at an estimated $4–5 billion. The program faced significant setbacks, including Germany's refusal to grant export licences for MTU diesel engines, forcing a switch to Chinese-made CHD-620 engines, alongside further delays caused by the COVID-19 pandemic, before production accelerated at Wuchang Shipbuilding's facility from 2024 onwards. With eight total submarines planned, the Hangor-class will dramatically expand Pakistan's AIP-equipped submarine fleet from three to eleven boats, potentially positioning the Pakistan Navy among Asia's largest submarine operators. Senior naval leadership has framed the fleet's strategic purpose around protecting sea lines of communication across the Arabian Sea and Indian Ocean while serving as a credible deterrent against potential aggression.
Key Takeaways
- 1. The commissioning of PNS/M Hangor represents a transformational leap for Pakistan Navy's subsurface warfare capabilities, nearly quadrupling its AIP-equipped submarine fleet to 11 boats
- 2. Germany's refusal to export MTU diesel engines forced a critical redesign around Chinese CHD-620 engines, highlighting how export controls and geopolitical decisions can significantly disrupt major defence procurement programs
- 3. Pakistan's strategic pivot from European (German HDW Type 214) to Chinese (CSOC S26-derivative) submarines deepens its defence-industrial dependence on China, reinforcing the broader Sino-Pakistani strategic partnership
- 4. The Hangor-class submarines are explicitly positioned to secure Arabian Sea and Indian Ocean sea lines of communication, signalling Pakistan's intent to project greater maritime deterrence in a strategically vital region
- 5. The scale of the program — eight submarines plus four Type 054A/P frigates ordered from China — suggests a comprehensive and coordinated naval modernization strategy designed to shift the regional naval balance, particularly vis-à-vis India
