India is soon going to acquire 6 German Submarines in next few months with a proven fuel cell based AIP( Air Independant Propulsion) being one of the main requirements asked by the Indian Navy

Lets explore what is AIP, what is its importance, how many types of AIP are there and which is the best among them? One of the biggest disadvantage of SSKs (Diesel Electric submarines) is that they need to snorkel (resurface the submarine for oxygen) after a relatively short amount of time which makes them vulnerable to the enemy.

With the use of AIP SSK can stay underwater for a very long amount of time, which will help them stay undetected by the enemies.

It will also feature Serpentine Air Intake similar to F35 and AMCA. It will be able to perform Autonomours Take off and Landing.

It will feature an AESA antenna for communication and an EOTS for target tracking A Serpentine Air Intake is used to hide the highly reflective engine compressor fan blades from enemy radar, reducing the aircraft's radar cross-section.

A 2D TV nozzle was developed for SWiFT which also reduced the IR signature of the aircrft by 60%
