Q10. With respect to the Air Independent Propulsion Technology (AIP), consider the following statements:

1. It is a technology for conventional non-nuclear submarines.
2. It allows a conventional submarine to remain submerged for much longer than ordinary diesel-electric submarines.
3. Installing AIP decreases the length and weight of the boats.

Which of the statements given above is/are correct?

1. 1 and 2 only
2. 2 only
3. 3 only
4. 1, 2 and 3

A – Explanation

• Air Independent Propulsion Technology (AIP) is a technology for conventional non-nuclear submarines. Hence, statement 1 is correct.Submarines are essentially of two types:conventional and nuclear. The conventional submarines use diesel-electric engines, which require them to surface almost daily to get atmospheric oxygen for fuel combustion.If fitted with an AIP system, the submarine will need to take in oxygen only once a week.The indigenously developed AIP, which is one of the key missions of the Naval Materials Research Laboratory (NMRL – DRDO), is considered one of the ambitious projects of the DRDO (Defence Research and Development Organisation) for the Navy.AIP technology allows a conventional submarine to remain submerged for much longer than ordinary diesel-electric submarines. Hence, statement 2 is correct.Installing AIP increases the length and weight of the boats, requires pressurised liquid oxygen (LOX) storage on-board and supply for all three technologies. Hence, statement 3 is not correct.
