Indigenous AIP System for Indian Navy Reaches Milestone
Source:PIB ↗
આ શા માટે મહત્વનું છે
Air Independent Propulsion (AIP) technology drastically increases the operational stealth and submerged endurance of conventional submarines, acting as a force multiplier for the Indian Navy in the Indo-Pacific region. This development underscores India's push towards defense indigenization and technological self-reliance.
સારાંશ
The Indian Navy and DRDO have achieved a crucial milestone in submarine technology with the inauguration of the Setting to Work Phase-2 Activity for the indigenous Air Independent Propulsion (AIP) system. Developed by NMRL with L&T, this system enhances the underwater endurance and stealth of conventional diesel-electric submarines, bolstering India's defense self-reliance.
મુખ્ય મુદ્દા
- The Indian Navy and DRDO achieved a major milestone for the indigenous Air Independent Propulsion (AIP) system by inaugurating the Setting to Work Phase-2 Activity.
- The AIP system is being developed by Naval Materials Research Laboratory (NMRL) with Larsen & Toubro (L&T) as the manufacturing partner.
- AIP significantly enhances the submerged endurance and stealth capabilities of diesel-electric submarines by allowing them to stay underwater longer without surfacing for air.
- This initiative is a critical step towards Aatmanirbhar Bharat (self-reliance) in cutting-edge naval defense technologies.

સંલગ્ન સ્થિર ખ્યાલો
How does an Air Independent Propulsion (AIP) system work in diesel-electric submarines?
- Snorkel dependency: Conventional limitation: Diesel-electric submarines must surface or use a snorkel to draw atmospheric oxygen for diesel generators to recharge batteries.
- Submerged power: AIP mechanism: It provides electrical power to drive propulsion motors and hotel loads while submerged without needing atmospheric oxygen.
- Stealth boost: Stealth advantage: Drastically reduces the frequency of surfacing, thereby minimizing radar and thermal signatures and lowering detection risks.
