China Delivers First Hangor Class Submarine to Pakistan Capable of Firing Nuclear-Tipped Missiles

SANYA, China - In a historic milestone for Pakistan's maritime defense, China has formally handed over the first of eight advanced Hangor-class submarines to the Pakistan Navy, marking a quantum leap in Islamabad's underwater warfare capabilities and strategic deterrence posture in the Arabian Sea and beyond.

The commissioning ceremony was held in the Chinese port city of Sanya, with Pakistani President Asif Ali Zardari and Chief of Naval Staff Admiral Naveed Ashraf in attendance, according to a statement from Pakistan's military . The event represents the culmination of a nearly $5 billion defense contract signed between the two all-weather allies in 2015 .

Nuclear-Capable Strike Platform

The Hangor-class submarine, an export variant of China's Type 039A Yuan-class design, is equipped with Air Independent Propulsion (AIP) technology that allows the vessel to remain submerged for two to three weeks without surfacing-dramatically enhancing its stealth and operational endurance compared to conventional diesel-electric submarines .

Most significantly, the submarine platform is compatible with Pakistan's Babur-3 submarine-launched cruise missile (SLCM), which is nuclear-capable and has an official range of 450 kilometers . This integration potentially provides Pakistan with a credible third leg of its nuclear triad, complementing its land-based ballistic missiles and air-delivered nuclear weapons .

Technical Specifications and Capabilities

The Hangor-class submarine boasts a displacement of approximately 2,800 tons and stretches roughly 77 meters in length . It can achieve speeds of up to 20 knots while submerged and is operated by a crew of around 40 personnel .

Key features include:

• Six 533mm torpedo tubes capable of launching heavyweight torpedoes and anti-ship cruise missiles 

• Advanced AIP system enabling extended submerged operations without snorkeling

• Optronic scopes replacing traditional periscopes

• Electronic Support Measures (ESM) and sophisticated sonar systems including hull-mounted, flank, towed array, and mine-avoidance capabilities 

• Secure encrypted communication systems enabling reliable connectivity with shore commanders while submerged 

The multi-role combat platform can deploy a wide array of munitions, including heavy-weight torpedoes (HWT), anti-torpedo decoys, submarine-launched anti-ship cruise missiles, and land-attack cruise missiles .

Eight-Submarine Fleet by 2028

Under the comprehensive agreement, Pakistan will acquire a total of eight Hangor-class submarines. Four vessels are being constructed in China, with the first now formally handed over. The remaining four are being built domestically at Karachi Shipyard & Engineering Works under a comprehensive technology transfer arrangement .

The fourth China-built submarine, named PNS Ghazi, was launched in December 2025 at the Wuchang Shipbuilding Industry Group's Shuangliu Base in Wuhan, marking the completion of construction for all four China-built boats . All four are now undergoing rigorous sea trials and are expected to begin entering service throughout 2026 .

The full fleet of eight submarines is expected to be operational by 2028, which will more than double Pakistan's current submarine fleet from its aging inventory of Agosta and Cosmos-class platforms .

Strategic Significance

Admiral Naveed Ashraf called the induction "an important milestone to bolster our maritime defence and modernize our fleet with cutting-edge technology," stating that the Hangor-class submarines will be "a key to preserving maritime order and stability in the region and play a role in deterring aggression" .

The timing of the induction is significant, coming amid ongoing tensions with India and following last year's four-day war in which Pakistani forces demonstrated their conventional military capabilities. The submarines are intended to strengthen Pakistan's anti-access/area-denial (A2/AD) posture in the Arabian Sea, complicating adversary surface operations and undersea tracking in contested waters .

Historical Legacy

The Hangor-class name carries deep historical resonance for the Pakistan Navy. The original PNS Hangor, a French Daphne-class submarine, famously sank the Indian frigate INS Khukri during the 1971 war-a feat that remains a source of pride for Pakistan's naval establishment . The new Hangor-class is designed to continue this legacy of underwater dominance.

Technology Transfer and Indigenous Capacity

Beyond immediate military applications, the project is expected to catalyze Pakistan's domestic shipbuilding capacity. The technology transfer component provides Pakistani engineers and shipbuilders with technical expertise, workforce development, and future sustainment capabilities .

A Pakistani government official indicated that once the indigenous construction program matures, "We will also be in a position to offer their exports under our defence production in future" .

Regional Implications

The induction of AIP-equipped submarines with nuclear missile capability significantly alters the naval balance in the Northern Indian Ocean region . While India maintains a larger naval force, including nuclear-powered submarines and aircraft carriers, the Hangor-class provides Pakistan with a potent asymmetric capability to threaten Indian warships and commercial shipping close to its coast .

India is currently pursuing its own submarine modernization program under Project 75-I, which aims to induct six diesel-electric submarines with indigenous AIP technology, though the program has faced delays .

China-Pakistan Strategic Partnership

The Hangor-class submarine project represents the deepening of China-Pakistan defense cooperation, which has already seen the induction of J-10C fighter jets, jointly developed JF-17 Thunder aircraft, and various missile systems . The submarines add a critical maritime dimension to the strategic partnership.

The handover ceremony in Sanya was witnessed by President Asif Ali Zardari, underscoring the political importance Islamabad attaches to the project . As one of the largest and most sophisticated foreign military procurements in Pakistan's history, the Hangor program reaffirms China's commitment to helping Pakistan achieve self-reliance in advanced defense technologies .
