The correct answer is option 'C': Both 1 and 2.
Explanation:
1. Air Independent Propulsion (AIP) System allows longer submergence than a conventionally propelled submarine:
The Air Independent Propulsion (AIP) system is a technology used in submarines that allows them to operate underwater for longer periods of time without the need to surface. Conventionally propelled submarines rely on diesel engines for propulsion, which require oxygen to operate. As a result, they need to surface regularly to intake fresh air and recharge their batteries. This limits their ability to remain submerged for extended periods.
In contrast, submarines equipped with an AIP system can generate their own oxygen and power, allowing them to remain submerged for longer durations. AIP systems typically use fuel cells or Stirling engines to generate electricity, which can be used to power the submarine's propulsion system and other onboard systems. By reducing the reliance on diesel engines, AIP systems significantly extend the submerged endurance of submarines, enhancing their stealth capabilities and operational effectiveness.
2. Air Independent Propulsion (AIP) System decreases the noise levels, making it hard to detect the submarines:
One of the key advantages of an AIP system is the reduction in noise levels produced by the submarine. Conventionally propelled submarines, especially when running on diesel engines, generate significant noise that can be detected by sonar systems employed by anti-submarine warfare (ASW) forces. This makes them vulnerable to detection and tracking.
AIP systems, on the other hand, use quieter propulsion technologies such as fuel cells or Stirling engines, which produce less noise compared to conventional diesel engines. This reduction in noise signature makes it harder for enemy forces to detect and track the submarine using passive sonar systems. As a result, submarines equipped with AIP systems gain a significant advantage in stealth and remain undetected for longer periods, increasing their survivability in hostile environments.
In conclusion, both statements are correct. The Air Independent Propulsion (AIP) system allows longer submergence than conventionally propelled submarines and decreases the noise levels, making it harder to detect the submarines.

With reference to the Air Independent Propulsion (AIP) System, conside...
Recently, Larsen & Toubro and the Defence Research and Development Organisation (DRDO) signed a contract for the realisation of two Air Independent Propulsion (AIP) System Modules for Kalvari Class of submarines of the Indian Navy.
- With the emergence of submarines, there was a problem finding satisfactory forms of propulsion underwater.
- AIP is mostly implemented as an auxiliary source, with the traditional diesel engine handling surface propulsion.
- Most of these systems generate electricity, which in turn drives an electric motor for propulsion or recharges the boat’s batteries.
- AIP allows longer submergence than a conventionally propelled submarine.
- A typical conventional power plant provides 3 megawatts maximum, and an AIP source around 10 per cent of that. A nuclear submarine’s propulsion plant is much greater than 20 megawatts.
Key features of the AIP system:
- It allows the submarines to stay for longer hours in water. The submarines need to come to the surface of the water to charge their batteries. This is reduced by AIP System.
- It decreases the noise levels made by the submarines. This makes it hard to detect the submarines.
- Types of AIP: Open-cycle systems, Closed-cycle diesel engines, Closed-cycle steam turbines Stirling cycle engines and Fuel cells.
Hence both statements are correct.
