Quick Revision: INS Nipun is India’s second indigenously built Deep-Sea Diving Support Vessel (DSV) with a 300-metre diving depth capability, designed for submarine rescue, disaster relief, and deep-sea operations.

Why is this in the news?

The commissioning of INS Nipun, the second Diving Support Vessel (DSV) of the Nistar-class, marks a significant augmentation of the Indian Navy’s deep-sea diving and submarine rescue capabilities. This vessel, commissioned on 31 August 2026, enhances India’s operational readiness in contested maritime environments and supports disaster relief and humanitarian missions, reflecting the Navy’s focus on strategic preparedness amid evolving maritime threats.

Background

• The Indian Navy operates under the Ministry of Defence and is responsible for safeguarding India’s maritime interests, including coastal security, deep-sea operations, and submarine rescue.
• Submarine rescue operations are critical for mitigating risks associated with submarine accidents, which can pose significant threats to naval personnel and national security.
• The Nistar-class DSVs are designed to provide rapid submarine rescue capabilities, supporting the Indian Navy’s commitment to maintaining a robust and self-reliant maritime force.
• Hindustan Shipyard Limited (HSL), a Government of India-owned shipbuilding enterprise, is a key player in the indigenous construction of naval vessels, including submarines and support ships.
• India’s maritime strategy is shaped by the need to address emerging challenges in the Indian Ocean Region (IOR), including piracy, illegal fishing, and geopolitical tensions.
• The commissioning of INS Nipun follows the induction of its predecessor, INS Nistar, and aligns with the Navy’s broader modernisation efforts to enhance operational flexibility and technological self-sufficiency.

What is INS Nipun?

• INS Nipun is a Deep-Sea Diving Support Vessel (DSV) commissioned into the Indian Navy on 31 August 2026, designed to perform deep-sea diving operations and submarine rescue missions.
• It is the second vessel of the Nistar-class, following INS Nistar, and is built indigenously by Hindustan Shipyard Limited (HSL) in Visakhapatnam.
• The vessel has a length of 119.4 metres, a displacement of 10,500 tonnes, and is equipped to support diving operations up to a depth of 300 metres.
• Key operational capabilities include rapid submarine rescue, disaster relief operations, and humanitarian assistance, making it a versatile asset for the Indian Navy.
• Its deployment enhances the Indian Navy’s ability to respond to submarine emergencies, conduct underwater repairs, and support deep-sea exploration and salvage operations.
• The commissioning of INS Nipun underscores India’s commitment to indigenous defence manufacturing and the development of strategic maritime assets.

Prelims Practice Questions

Q1. Consider the following statements regarding the recently commissioned INS Nipun: 1. INS Nipun is a deep-sea diving vessel of the Nistar-class. 2. It has been commissioned by the Indian Navy to provide rapid submarine rescue capabilities. 3. The vessel is capable of supporting diving operations up to a depth of 300 metres. 4. It was built by Cochin Shipyard Limited. How many of the above statements are correct?

1. Only one
2. Only two
3. Only three
4. All four

Answer: Only three — Statements 1, 2, and 3 are correct. Statement 4 is incorrect as INS Nipun was built by Hindustan Shipyard Ltd, not Cochin Shipyard Limited.

Q2. Assertion (A): The commissioning of INS Nipun enhances India’s maritime disaster relief capabilities.
Reason (R): The vessel is designed to support diving operations up to 300 metres and can be deployed for humanitarian operations.

1. Both A and R are true, and R is the correct explanation of A.
2. Both A and R are true, but R is not the correct explanation of A.
3. A is true, but R is false.
4. A is false, but R is true.

Answer: Both A and R are true, and R is the correct explanation of A. — Both Assertion (A) and Reason (R) are true. INS Nipun’s capabilities, including supporting diving operations and deployment for humanitarian operations, directly enhance India’s maritime disaster relief capabilities. Thus, R correctly explains A.

Q3. Match the following columns regarding Indian naval vessels and their roles:

Column I (Vessel) Column II (Role)
A. INS Nipun 1. Aircraft carrier
B. INS Vikramaditya 2. Deep-sea diving and submarine rescue
C. INS Arihant 3. Nuclear-powered ballistic missile submarine
D. INS Vikrant 4. Indigenous aircraft carrier

1. A-2, B-1, C-3, D-4; A-1, B-2, C-3, D-4; A-4, B-3, C-2, D-1; A-3, B-4, C-1, D-2
2. answer_array_indexes_to_display_as_single_string_here_but_keep_JSON_valid_so_use_an_array_of_integers_for_answer_field_instead
3. answer_array_indexes_to_display_as_single_string_here_but_keep_JSON_valid_so_use_an_array_of_integers_for_answer_field_instead

Answer: ? — The correct matches are: A-2 (INS Nipun is a deep-sea diving vessel), B-1 (INS Vikramaditya is an aircraft carrier), C-3 (INS Arihant is a nuclear-powered ballistic missile submarine), D-4 (INS Vikrant is an indigenous aircraft carrier).
