Project 75 India often mentioned in defence news is associated with which branch of the Indian armed forces for building advanced submarines?

Introduction / Context:
Project 75 and its extended version Project 75 India are important programmes in India effort to strengthen its underwater warfare capabilities. These projects involve the construction of modern submarines with advanced stealth and combat features. General knowledge questions frequently ask which branch of the armed forces is linked to these projects, making this a key defence awareness topic.

Given Data / Assumptions:

- The question refers to Project 75 India, also written as P75I. - It asks which Indian armed force this project is associated with. - The options list the Indian Army, Indian Air Force, Indian Coast Guard and Indian Navy. - We assume awareness that submarine construction falls under naval warfare.

Concept / Approach:
Project 75 and Project 75 India are submarine acquisition and construction programmes intended to equip the Indian Navy with a new generation of conventional diesel electric submarines, some featuring air independent propulsion. These submarines are critical for sea denial, coastal defence and maritime security, all of which fall squarely within the role of the Indian Navy. Therefore, the project is directly associated with the Indian Navy, not the Army, Air Force or Coast Guard.

Step-by-Step Solution:
Step 1: Recognise that the phrase Project 75 India is used in news stories about submarine building contracts and strategic partnerships. Step 2: Recall that submarines are naval platforms operating under water to support maritime operations and deterrence. Step 3: Since submarines are not used by the Army or Air Force, immediately rule out those branches. Step 4: The Indian Coast Guard operates patrol vessels and aircraft for coastal security but is not the primary operator of advanced attack submarines. Step 5: Therefore select Indian Navy as the branch associated with Project 75 India.

Verification / Alternative check:
Reading defence news articles and official press briefings reveals that Project 75 covers the construction of Scorpene class submarines at Mazagon Dock for the Indian Navy, while Project 75 India plans an additional line of more advanced submarines. All such communications refer to the Indian Navy as the beneficiary service. Competitive exam guides on defence also summarise Project 75 India under the Indian Navy heading, which confirms the correct answer.

Why Other Options Are Wrong:
The Indian Army primarily operates land based forces such as infantry, armour and artillery, not submarines. The Indian Air Force is responsible for aerial warfare and does not manage submarine building programmes. The Indian Coast Guard protects coastal and maritime zones but typically operates surface vessels and aircraft, not advanced attack submarines.

Common Pitfalls:
Some candidates may confuse Project 75 with other numbered defence projects related to missiles or aircraft, leading them to consider the Air Force or Army. Others may not pay attention to the keywords in news headlines that clearly connect P75I to submarines. A simple memory trick is to associate the number 75 with the deep sea by picturing seventy five metres underwater and linking that image to the Indian Navy submarine programme.

Final Answer:
Project 75 India is associated with the Indian Navy and its programme to build advanced submarines.
