Pakistan has formally inducted its first Chinese-built Hangor-class submarine, marking the beginning of a significant expansion of its underwater fleet. The Hangor submarine, equipped with Air Independent Propulsion (AIP) technology, promises longer endurance and reportedly integrates the Babur-3 cruise missile, positioning it as a potential game changer for Pakistan's naval capabilities.
Hangor vs Indian Submarines
The Hangor class is often compared to India's Kalvari-class (Scorpene) submarines. While the Kalvari class is modern and stealthy, it lacks AIP technology, giving the Hangor a submerged endurance advantage. India's Arihant-class nuclear-powered ballistic missile submarines, however, offer strategic deterrence with nuclear propulsion and longer-range missiles, a capability Pakistan currently lacks.
AIP Advantage
AIP allows conventional submarines to remain submerged for weeks without surfacing, drastically reducing detection risk. Pakistan's Hangor fleet, once fully operational, could challenge Indian naval dominance in the Arabian Sea by enabling prolonged patrols near critical chokepoints.
Fleet Numbers and Delays
Pakistan plans to acquire eight Hangor-class submarines, with four built in China and four in Karachi. This will significantly boost its submarine fleet. Meanwhile, India's submarine modernization faces delays, including the Project 75I program for new AIP-equipped submarines, which has seen repeated setbacks.
Geostrategic Implications
The induction highlights China's growing role in Pakistan's military modernization. For India, the Hangor class adds a new dimension to the underwater contest. However, India retains advantages in nuclear submarines, anti-submarine warfare capabilities, and overall fleet size. The true balance will depend on technology, training, and operational strategies.
This report breaks down the technology, the AIP advantage, fleet numbers, nuclear submarine comparisons, China's increasing involvement, and the delays affecting India's own submarine programs.
