Ins Karanj

INS Karanj (S23) is a diesel-electric assault submarine based on the scorpene submarine of India, developed by DCNS, and built by Mazagon Dock Limited, a Mumbai-based Indian shipyard.

Karanj is outfitted with one of the most advanced sensors available and a comprehensive performance monitoring system that allows centralised propulsion and machinery control. Strong diesel engines can quickly charge batteries for a stealthy mission profile. Its modular design also allows for future enhancement of air-independent propulsion. It has a permanent magnet synchronous motor, making her among the quietest scorpene submarines in India. “We can boldly state that Karanj will be the first homegrown submarine,” stated Commanding Officer Captain Gaurav Mehta, who has served in the Navy for over 20 years. Let’s discuss more scorpene class submarines of India in detail.

Scorpene Submarine of India

Scorpène is a conventional submarine designed for export by the Naval Group. It highlights the Naval Group’s ability to deliver best-in-class submarines while facilitating efficient and effective transfers. The Chilean Navy, the Malaysian Navy, the Indian Navy, and the Brazilian Navy all have Scorpene submarines in service or building. The Scorpene design is adjusted to meet the needs of each fleet. As a result, the Brazilian Scorpène is slightly longer to accommodate a bigger crew, nearly double the patrol range and spans longer distances. Scorpène is well-suited to combat and operational efficiency. It’s an ocean-going submarine built for operations in shallow waters. Anti-surface and anti-submarine warfare, special operations, defensive minelaying, or information collection are some of its roles. Scorpène is a cutting-edge submarine that incorporates upgrades from the French Barracuda-Class fast-attack submarine.

Scorpene Submarine

Superior stealth features, including advanced acoustic silencing methods, low radiated noise levels, hydrodynamically optimised shape, and the ability to launch a crippling attack on an enemy utilising precision-guided missiles, have been guaranteed thanks to the state-of-the-art innovation used in the development of the Scorpene-class submarines. Torpedoes or tube-launched anti-ship missiles can be used to attack, which can still be released below and on the surface. The extra attention paid to numerous signatures adds to the stealthiness of this strong platform. These stealth qualities give it invulnerability that few submarines can achieve.

Anti-surface warfare, anti-submarine warfare, intelligence collection, mine laying, area surveillance, and other duties are all possible with Scorpene submarines. The submarine is designed to operate in all theatres, with provisions for cooperation with some other Naval Task Force elements. It’s a formidable platform that heralds a new age in submarine warfare. The first Scorpene-class submarine, INS Kalvari, was launched into the Indian Navy in 2017.

Propulsion Without The Use of Air

The French shipyard Direction des Constructions Navales (DCNS) is offering the Module d’Energie Sous-Marine Autonome (MESMA) system for Scorpène-class submarines. It’s simply a revised version of their nuclear propulsion engine that uses ethanol or oxygen to produce heat. Steam is generated by the oxidation of ethanol and saved oxygen at a pressure of 60 atm (6.1 MPa), which drives a traditional turbine power plant. Without an exhaust compressor, carbon dioxide from the exhaust can be released over at any depth. Each MESMA system costs between $50 and $60 million. It needs a fresh 8.3-metre (27-foot), 305-tonne hull section to be put just on Scorpènes, which allows a submarine to function for even more about 21 days beneath water based on speeds. For future Scorpène models, DCNS is also producing second-generation hydrogen fuel cell AIP units.

Guests of Recognition

According to the Navy, the former crew of the Karanj, a Russian-built Foxtrot class submarine that retired in 2003, was invited as special guests to the ceremony. To commemorate the 50th anniversary of the 1971 India–Pakistan conflict, the year 2021 has been specified as the ‘Swarnim Vijay Varsh.’ Under the command of then-Cdr Shekhawat, the old Karanj launched on September 4, 1969, in Riga, Latvia, in the former Soviet Union, also participated actively in the fight. Several officers or crew members were awarded medals for their bravery, along with the Vir Chakra to then-Commanding Officer Cdr Shekhawat, as per the Navy. Cdr MNR Samant, the old Karanj’s launching Commanding Officer, eventually becomes the first Chief of the Naval Staff.

Conclusion

The Scorpene submarines of India are among the world’s most technologically advanced conventional submarines. The Indian Navy will use the submarines for missions like area surveillance, retrieval of information, anti-submarine warfare, and anti-surface warfare, including minelaying. Six torpedo-launching tubes, 18 heavy armaments, tube-launched MBDA SM-39 Exocet anti-ship missiles, and precision-guided weapons all seem to be aboard the submarines. It can launch debilitating strikes on enemy targets on the surface or underwater. Furthermore, the attack submarines can move at a maximum submerged speed of around 20 knots and, therefore, stay down for 21 days.

Ans : The submarine is dedicated after INS Karanj (S21), a scorpene submarine of India that enlisted in the Navy from 1969 to 2003. It was titled after Karanja island, popularly referred to as Uran island, within Maharashtra’s Raigad district.

Ans : The Mazagon Dock Shipbuilders Limited (MDL) Mumbai is building six Scorpene-class submarines in cooperation with M/s Naval Group, France. The INS Karanj is just a smaller submarine than a nuclear submarine. This makes it the most destructive and fastest submarine ever built.

Ans : The six Kalvari-class submarines are being constructed in India as part of the Indian Navy’s Project-75. They were developed by the French company DCNS. Four of the six submarines intended have been delivered to the Indian Navy: the Khanderi, Kalvari, Karanj, and Vela.

Ans : The Scorpene-class submarine has been designed using cutting-edge technologies to achieve superior stealth. Effective acoustic absorption techniques with low radiated noise levels and a hydrodynamically efficient form are part of this.

Ans. The Indian Navy has received its third Scorpene submarine, the INS Karanj, which will be launched in Mumbai. This is one of the six submarines built as part of Project 75. The submarine is named after INS Karanj (S21), a submarine that served in the Navy from 1969 to 2003 and was named after Karanja island, also renowned as Uran island, in Maharashtra’s Raigad district.
