Pakistan commissioned its first Chinese-built Hangor-class attack submarine in Sanya, China, on Thursday [1].

The acquisition represents a significant shift in regional naval dynamics by introducing advanced stealth technology to the Pakistan Navy. This move deepens the strategic defense partnership between Islamabad and Beijing while enhancing Pakistan's ability to monitor and secure its maritime borders.

President Asif Ali Zardari and the chief of the Pakistan Navy attended the ceremony in Sanya [1]. The vessel is the first of eight submarines planned under a comprehensive deal with Chinese shipbuilders [2]. These attack submarines are designed to provide a modern deterrent capability in the region.

A key technical feature of the Hangor-class is the use of Air-Independent Propulsion (AIP) [3]. This technology allows the submarine to remain submerged for longer periods compared to conventional diesel-electric vessels, reducing the likelihood of detection by enemy sonar.

The procurement of these eight vessels [2] is intended to modernize the fleet and ensure a higher state of readiness. By integrating Chinese naval technology, Pakistan aims to offset regional imbalances in underwater warfare capabilities.

The ceremony in China underscores the growing reliance on Beijing for high-end military hardware. The delivery of the first unit marks a transition from the planning phase to the operational deployment of the Hangor-class fleet.

“The vessel is the first of eight submarines planned under a comprehensive deal with Chinese shipbuilders.”

The introduction of AIP-equipped submarines significantly increases the stealth and endurance of the Pakistan Navy, complicating the maritime surveillance efforts of regional rivals. This deal solidifies China's role as Pakistan's primary security provider and creates a long-term dependency on Chinese maintenance and technical support for its underwater fleet.
