The Indian Navy has inducted its third diesel electric Scorpene-class submarine INS Karanj into service.
The submarines were designed by French shipbuilding firm DCNS by partnering with Spanish shipbuilding company Navantia.
The Scorpene class submarines are one of the best conventional diesel submarines in the world.
The submarine has highly superior stealth features, such as advanced acoustic silencing, low radiated noise levels and ability to attack with precision-guided weapons on board.
The Indian Navy will be using these submarines for surveillance, intelligence gathering, anti-submarine warfare, anti-surface warfare and minelaying operations.
The Submarine has a permanent magnetic synchronous motor, allowing it to be one of the silent submarines in the world.
The Submarine has the ability to remain submerged for 21 days. It has a diving depth of more than 350m.
This is a project of Indian Navy under which six latest technology naval submarines were built. The project will be completed by 2022.
