Pakistan Navy Commissions First Hangor-Class Submarine in China

Why It Matters

The Hangor‑class adds a credible, stealthy strike platform to Pakistan’s navy, bolstering its anti‑access/area‑denial (A2/AD) posture and safeguarding vital sea lanes in the Indian Ocean. It also underscores China’s role as a key arms supplier, reshaping regional naval balance.

Key Takeaways

• Pakistan commissioned first Hangor-class submarine, PNS/M Hangor, in China.
• Hangor class derived from China’s Type 039B Yuan, eight units ordered.
• Submarine features AIP, advanced sensors, and potential Babur-3 cruise missiles.
• Enhances Pakistan's A2/AD capability and secures Indian Ocean sea lanes.
• Production split: four built in Pakistan, four in China, delivery through 2028.

Pulse Analysis

The commissioning of PNS/M Hangor reflects the deepening strategic partnership between Pakistan and China, a relationship that has produced a series of joint defence projects over the past decade. The Hangor program, initiated in 2015, originally slated delivery of eight submarines between 2022 and 2028, has experienced modest delays, with the first vessel finally entering service in 2026. By building half of the fleet at Pakistan’s Karachi Shipyard & Engineering Works, the deal not only transfers technology but also expands local industrial capacity, positioning Pakistan to sustain future naval upgrades.

Technically, the Hangor‑class is based on the Chinese Type 039B Yuan platform, featuring a 76‑metre hull, 2,800‑ton displacement and an air‑independent propulsion (AIP) system that extends submerged endurance. While official specifications remain sparse, analysts infer the use of a Stirling‑type AIP and advanced sonar suites, aligning the boats with modern diesel‑electric standards. Integration of Pakistan’s indigenous Babur‑3 submarine‑launched cruise missiles would grant deep‑strike capability, complementing the existing Agosta‑90B fleet undergoing Turkish‑led modernization. The submarines thus fill a critical gap, offering stealthy surveillance and strike options across the Arabian Sea.

Strategically, the Hangor‑class bolsters Pakistan’s ability to protect its maritime trade routes and the broader Indian Ocean sea‑lines of communication, which are vital for global energy flows. Enhanced A2/AD capacity may deter adversarial naval activity and influence power dynamics with neighboring India and beyond. As the remaining vessels roll out through 2028, the fleet will provide Pakistan with a credible deterrent, while reinforcing China’s footprint in South Asian naval affairs, a development that will shape regional security calculations for years to come.
