The speed of manufacturing warships has improved ever since the new method of “integrated construction” has been adopted. Mahendragiri is named after a mountain peak in Eastern Ghats located in Odisha.
Three Nilgiri-class warships are a follow-up of Shivalik-class frigates but with vastly improved stealth features, advanced weapons and sensors and platform management systems.
The Nilgiri warships are built with new radar-absorbing coatings, composite materials and shape superstructures that avoid radar detection. Mahendragiri will have a 76mm main gun, two 30 mm AK-630M anti-aircraft artillery systems, two torpedo tubes, launchers for eight BrahMos supersonic cruise missiles and 32 Barak-8 surface to air missiles. Its main radar will be MF-STAR.
The Nilgiri-class warships have been designed in-house by Indian Navy’s Warship Design Bureau, the pioneer organisation for all warship design activities. A substantial 75 per cent of the orders for equipment and systems of the Nilgiri class have been made to indigenous firms, including micro, small and medium enterprises (MSMEs).
Four of Nilgiri-class warships are under construction at Mazagon Dock Shipbuilders Limited, Mumbai, and three at Garden Reach Shipbuilders and Engineers Limited, Kolkata. Both shipbuilders are public sector enterprises under the Ministry of Defence.
