Hangor Class Submarine | 01 May 2024

Recently, China has launched the first of eight Hangor-class submarines being built for Pakistan. It is a diesel-electric attack submarine.

It is bigger than the Indian Navy's Kalvari class submarines, with a displacement of 2,800 tons compared to 1,775 tons for the Kalvari class.
The Hangor class has Air independent propulsion (AIP).
- AIP allows submarines to stay submerged for longer periods.
- AIP is planned to be installed on the first Scorpene class submarine INS Kalvari in 2024.
In terms of armament, both carry torpedoes and anti-ship missiles, The Kalvari class likely has more modern and battle-tested armament.
The bigger size of the Hangor class may hamper its manoeuvrability in littoral waters compared to the smaller Kalvari class.
