Pakistan Moves Forward with Chinese Hangor-Class Submarines, Boosting Naval Power
Pakistan is moving forward with the induction of eight advanced Chinese Hangor-class submarines. Yesterday, the nation’s first Hangor-class submarine, PNS Hangor, was formally commissioned into the Pakistan Navy at a ceremony held in Sanya, China .
This move represents the most significant modernization effort in the history of the Pakistan Navy and is a key component of the deepening defense partnership between Islamabad and Beijing.
🚢 The Hangor-Class Program: Details & Timeline
The Hangor-class project is Pakistan’s most ambitious naval acquisition to date .
- Total Fleet Size: Eight submarines will join the fleet .
- Construction Plan: Under the multibillion-dollar deal, the first four submarines are being built in China, while the remaining four are being constructed at the Karachi Shipyard and Engineering Works (KSEW) under a comprehensive technology transfer agreement .
- Sea Trials & Commissioning (2024-2026):
- All four Chinese-built boats (PNS Hangor, PNS Shushuk, PNS Mangro, PNS Ghazi) are currently undergoing rigorous sea trials and are in the final stages of being handed over to Pakistan .
- PNS Hangor, the first of class, was officially commissioned on April 30, 2026 .
- Timeline: The entire class is expected to be in service by the early 2030s.
🛡️ Advanced Capabilities: Stealth & Endurance
The new submarines represent a generational leap in capability over the older French-origin Agosta 90B submarines (Khalid-class) currently in service .
- Air-Independent Propulsion (AIP): A key feature of the Hangor-class is its AIP system. This technology allows the submarine to stay submerged for weeks or even months without needing to surface to charge batteries, dramatically improving stealth and survivability .
- Stealth Technology: The submarine features a hydro-dynamically optimized hull and sound-absorbing coatings for enhanced stealth .
- Weaponry & Sensors: The Hangor-class is armed with heavy-weight torpedoes and modern anti-ship cruise missiles with land-attack capability .
- It is equipped with advanced sensors, including an Optronic Scope, Electronic Support Measures (ESM), and sophisticated sonar arrays (hull-mounted, flank, towed array) .
- Legacy of the Name: The class is named after the legendary PNS Hangor, which sank the Indian frigate INS Khukri during the 1971 war—the first submarine kill since WWII .
🌏 Strategic Context: Regional Balance & China Ties
The induction of these advanced submarines occurs within a specific geopolitical framework.
- Regional Rivalry: The primary driver for Pakistan is to maintain a strategic balance with India, which is also modernizing its own navy . The submarines are intended to secure Pakistan’s Sea Lines of Communication (SLOCs) in the Arabian Sea and the Indian Ocean .
- Role of Chinese-Origin Platforms: Pakistan’s military has increasingly relied on Chinese hardware. This includes the J-10C fighter jets, which were used in last year’s conflict with India, and the Babur-class corvettes .
- The AIP Advantage: Unlike the older Agosta-class boats, only two of which had the shorter-range MESMA AIP system retrofitted, the new Hangor-class submarines are being built from the keel up with cutting-edge AIP technology . This makes them significantly quieter and more capable of long-range patrols.
The commissioning of the first Hangor-class submarine signals a new chapter for Pakistan’s naval power, enhancing its ability to protect its maritime borders and project power in the Indian Ocean.
