Mumbai, Jan 30 (IANS): The third Scorpene class submarine, Karanj, will be launched in the sea in Mumbai on Wednesday, an official statement said on Monday.

The submarine will be launched at the Mazagon Dock Shipbuilders Ltd and Navy Chief Admrial Sunil Lanba will be the chief guest.

First of the Scorpene class submarines, INS Kalvari was commissioned in Mumbai last December.

The second in the series of six submarine project, INS Khanderi was undergoing sea trials and all the submarines are due to be inducted gradually into the Indian Navy by 2020.

The state-of-the-art features of the Scorpenes include superior stealth and ability to launch crippling attacks with precision-guided weapons.

The attacks can be carried out with torpedoes both while submerged or on the surface -- in all war theatres including the tropics, giving it an unmatched invulnerability.

The submarine has an overall length of 67.5 metre and a height of about 12.3 metres. The hull form, fin and hydroplanes are specifically designed to produce minimum underwater resistance.
