P-75I (or P-75 India) project refers to manufacture of
- A.Diesel-electric submarines.
- B.Nuclear-powered submarines.
- C.Aircraft carrier warships.
- D.Field guns.
Correct answer
Explanation
The correct answer is A, Diesel-electric submarines. Project 75 India, or P-75I, is the Indian Navy's plan to build six advanced conventional diesel-electric submarines in India. Its key requirement is Air Independent Propulsion, which lets a conventional submarine stay submerged for much longer without surfacing to charge its batteries. The submarines are to be built in an Indian shipyard with a foreign technology partner under the Strategic Partnership model of the Defence Acquisition Procedure, to build up the country's own submarine-making skills. It follows Project 75, under which Mazagon Dock in Mumbai built six Kalvari-class Scorpene submarines with French help. Option B is wrong because India's nuclear-powered ballistic missile submarines, the Arihant class, come from the separate Advanced Technology Vessel programme. Option C is wrong because the indigenous aircraft carrier INS Vikrant was built by Cochin Shipyard under a different project. Option D is wrong because field guns such as Dhanush and the Advanced Towed Artillery Gun System belong to Army artillery programmes. Exam tip: P-75 is the Kalvari-class Scorpene; P-75I is six AIP-equipped diesel-electric submarines.
