Subsurface Counterbalance: Pakistan Navy Demonstrates Combat Readiness with Maiden Hangor-Class Missile Firing

 

On September 26, 2026, the Pakistan Navy successfully executed the maiden live weapon firing from its first Hangor-class submarine, PNS/M Hangor, in the North Arabian Sea. Witnessed at sea by Chief of the Naval Staff Admiral Naveed Ashraf, the operation involved the precision engagement of a long-range surface target using an anti-ship cruise missile. Fired only months after the lead boat completed its delivery voyage from China to Karachi following commissioning, this live-fire validation confirms that the platform’s combat system, sensors, and weapons integration are fully operational, marking a significant milestone in Pakistan's multi-billion-dollar effort to modernize its underwater fleet.

The integration of the Hangor-class—a custom variant of China's Type 039B/041 Yuan-class diesel-electric submarine—directly addresses the growing numerical and qualitative asymmetry in the Indian Ocean Region (IOR). Under a landmark eight-boat procurement agreement with China, four hulls are being constructed at China Shipbuilding Trading Company (CSTC) yards, while the remaining four are being assembled locally at Karachi Shipyard & Engineering Works (KS&EW). Equipped with Air-Independent Propulsion (AIP) systems, these platforms provide significantly extended underwater endurance compared to legacy Agosta 90B boats, allowing the Pakistan Navy to maintain covert, persistent sea-denial patrols along critical maritime chokepoints and coastal approaches without the frequent need to snorkel.

Beyond standard surface-warfare capabilities, the operationalization of the Hangor class enhances Pakistan’s strategic deterrence posture at sea. While the recent drill validated long-range anti-ship cruise missile targeting, the platform’s large-diameter torpedo tubes and modern combat management system also provide the structural foundation for deploying the Babur-3 submarine-launched cruise missile (SLCM). The capability to launch nuclear-capable, low-flying cruise missiles from concealed subsurface positions provides Islamabad with a survivable second-strike vector, reinforcing its doctrine of full-spectrum deterrence against potential adversary pre-emptive strikes or blockades.

From a tactical perspective, the arrival of AIP-equipped stealth submarines fundamentally alters anti-submarine warfare (ASW) dynamics in the Arabian Sea. Operating in the shallow, acoustically complex littoral waters off the coastline, the Hangor class's reduced acoustic signature makes passive sonar detection exceptionally difficult for opposing surface task forces and airborne maritime patrol platforms. By distributing strike options across multiple AIP-enabled submarines, the Pakistan Navy forces regional opponents to allocate disproportionate ASW assets for screening capital ships, complicating adversary operational planning and raising the threshold for hostile naval intrusions.

Ultimately, the successful missile engagement by PNS/M Hangor signals that the Pakistan-China naval partnership is transitioning from industrial delivery to real-world combat capability. As additional hulls undergo fitting-out and trial phases in both Wuhan and Karachi, the progressive induction of all eight Hangor-class submarines over the coming years will establish a formidable underwater barrier. For the Pakistan Navy, achieving combat readiness on its flagship AIP submarine ensures a robust sea-denial capability, safeguarding vital sea lines of communication while preserving a delicate strategic balance across the northern Indian Ocean.
