India is the country called to be the power of the 21st century, due to its demographic, economic and technological situation. However, it has certain shortcomings in the naval field. It is for this reason that it seeks to acquire an important fleet to reinforce its Navy.
The Asian country has been looking for submarines for some time, and Spain and Germany are the two countries that have the submarines that interest it the most. These are the S-80 from Navantia (Spanish) and the Type 241 from Thyssenkurpp Marine Systems (German).
However, the Spanish model would be superior in certain aspects, such as size: the S-80 has a surface of 80 meters that holds about 2,200 tons, unlike the Type 214, which has 1,700 tons spread over 65 meters.
What is the S-80 of Spain like?
The S-80 submarines have an overall length of 80.8 meters, a diameter of 7.3 meters and a submerged displacement of around 3,000 tons. Its technological contributions include the platform combat and control system from Navantia Sistemas, and a revolutionary anaerobic propulsion system developed by Navantia that provides great stealth in immersion, called BEST-AIP.
This propulsion system independent of the atmosphere allows it to obtain electrical energy, from fuel cells that use technology from the aerospace sector, at any depth. Thus, it will be able to remain for weeks without going out to periscopic level, which will improve its discretion, the main attribute of a submarine.
