INS Karanj reborn as Navy's Scorpene class submarine: 10 things to know

INS Karanj
Indian Navy launched the third Scorpene class Karanj submarine at Mazagon Dock Shipbuilders Limited (MDL) in Mumbai on Wednesday. Erstwhile Karanj was commissioned in Indian Navy on September 4, 1969 and was retired on August 1, 2003. Today she is reborn in a new avatar, according to Indian Navy's Twitter handle. Navy Chief Admiral Sunil Lanba's wife Reena Lanba launched the submarine, which has been constructed by shipbuilder Mazagon Dock Limited (MDL) here.

The state-of-the-art features of the Scorpenes include superior stealth and ability to launch crippling attacks with precision-guided weapons. First of the Scorpene class submarines, INS Kalvari was commissioned in Mumbai last December. The Scorpene submarines are a primary modernization requirement of the Indian Navy, which is currently faced with an ageing submarine fleet, and that too when the Chinese navy has a growing presence in the Indian Ocean.
