INS Khanderi vs INS Kalvari: India has made another achivement in its naval power with the induction of Scorpene-class submarines under Project 75. These submarines are modern diesel-electric attack subs that are known for being very quiet and very hard to detect. They have been built in Mumbai by Mazagon Dock Shipbuilders Limited in partnership with the French Naval Group. The plan under Project 75 is to make six of these advanced submarines for the Indian Navy. Their job is not just to fight but also to gather intelligence, do surveillance missions, and strike with deadly accuracy using torpedoes and missiles.
Among the six submarines, INS Kalvari and INS Khanderi stand out as frontline warriors. Both belong to the same class but they joined the Navy at different times and each carries its own special value.

INS Kalvari
INS Kalvari was the first of these submarines to join the Indian Navy. It was commissioned on December 14, 2017, and the name comes from a powerful deep-sea tiger shark, which shows strength and aggression. Kalvari opened a new chapter for India because it was the first Scorpene submarine to be inducted. This meant India had finally stepped into a new era of modern underwater warfare.
Features
The submarine carries torpedoes and Exocet anti-ship missiles, which give it the ability to strike both underwater and at sea targets. It also has an advanced sonar system and modern sensors, which make it perfect for spying and surveillance.
The design is such that it can move very quietly, making it extremely hard for enemies to track. When it joined the Navy, it showed the success of the first phase of Project 75 and gave India confidence that the plan was working well.
INS Khanderi
on September 28, 2019, the Navy welcomed INS Khanderi. It was the second submarine of this class, and its name comes from Khanderi, an island fort near Mumbai that had great importance during the time of the Maratha Navy. By bringing this name into the present, the Navy kept its link with India’s own naval history while also showing off modern strength.

Features
Khanderi looks similar to Kalvari in design. It also runs on diesel-electric propulsion and has strong stealth technology. Like Kalvari, it can carry torpedoes and SM39 Exocet missiles, up to 18 in number. But Khanderi has more refinements.
