Pakistan commissions first Hangor-class submarine. Advancing undersea capabilities

The induction represents a tangible enhancement of Pakistan’s undersea warfare capabilities amid evolving security dynamics across the Arabian Sea and the wider Indian Ocean.

According to Rear Admiral Ahmed Hussain, Director General Public Relations (Navy), the programme is intended to strengthen deterrence and safeguard critical maritime interests.

- Disruptions at key maritime choke points are increasingly affecting global trade and energy security. Maintaining a stable, rules-based maritime order requires technologically advanced naval forces, Ahmed Hussain stated.

Advanced conventional submarine platform

The Hangor-class is based on China’s Type 039B (Yuan-class) design, widely regarded as one of the most capable conventional submarine platforms available for export. A defining feature is its air-independent propulsion (AIP) system, which enables extended submerged operations without the need to surface for battery recharging.

This significantly enhances stealth, endurance and operational flexibility, allowing for prolonged deployments in strategically sensitive waters.

- Equipped with advanced weapons, modern sensors and AIP technology, Hangor-class submarines will play a key role in maintaining maritime stability in the region, the spokesperson noted.

While detailed specifications remain limited, the class is expected to field heavyweight torpedoes and anti-ship missiles, reinforcing its role as a credible sea-denial asset.

Strategic fleet expansion

The Hangor programme envisages a total of eight submarines, with construction split between Chinese shipyards and domestic facilities in Karachi. This approach supports both accelerated delivery and the development of indigenous shipbuilding capabilities.

As one of the largest defence procurement programmes in Pakistan’s history, it reflects a long-term commitment to strengthening maritime security and operational autonomy.

- These platforms will be instrumental in deterring aggression and ensuring the security of vital sea lines of communication across the Arabian Sea and the broader Indian Ocean region, Ahmed Hussain added.

Sea lines of communication (SLOCs) in this region remain critical to global trade and the transport of energy resources between Asia, the Middle East and Europe.

Regional security context

The commissioning comes amid intensifying naval competition in the Indian Ocean. Pakistan’s submarine modernisation is widely seen as part of a broader effort to maintain strategic balance with India, which is also expanding its undersea capabilities.

At the same time, the programme highlights the growing strategic alignment between Pakistan and China, extending beyond procurement to include technology transfer and industrial cooperation.

Eight Hangor-class submarines for Pakistan

The commissioning of the lead unit marks the beginning of a broader capability development cycle. Under the current programme, Pakistan is set to acquire a total of eight Hangor-class submarines, significantly expanding its undersea fleet over the coming years.

As additional units enter service, the Pakistan Navy will increase its operational reach and persistence beneath the surface, reinforcing its position in the evolving maritime security environment of the Indian Ocean.

From a global perspective, continued investment in undersea capabilities across the region will remain a key factor shaping maritime stability, trade security and strategic competition in the decades ahead.
