Description: The three Indian Navy destroyers of the Delhi class are the most modern and largest to be fully built in India. They began as Project 15 in 1977, initially as frigates to replace the Godavari class. They were manufactured at Mazagon Dock Limited in Mumbai.
The Delhi class is a hybrid of Soviet and Western designs, incorporating elements of the Sovremenny class destroyer, the Rajput class (Kashin-II) destroyer, and the Godavari class frigate.
The 6,700 tonne guided-missile destroyer INS Delhi is India's first "Stealth Warship". Described as the Navy's version of the Russian Kashin Class destroyer, the Delhi was the first Principal Surface Combatant to join the Indian Navy. The destroyer is fitted with sophisticated anti-ship, anti-aircraft and anti-submarine sensor and weapon systems.
INS Delhi is the first Indian warship to be fitted with air and surface search radar.
The 100 mm main gun at the bow of the ship is supplied by Russia. The vessel is equipped with four quad launchers. The surface-to-air missile system is the Russian Shtil. The missile's maximum range is 25 km. The ship has a surveillance capacity of over 350 km and can sterilise an area of 250 km.
The ships also have a quadruple torpedo launcher capable of hitting targets ranging from 50 km to 120 km. It is also equipped with two anti-submarine rocket launchers with 12 tubes. Their range is 6 km and the maximum engagement depth is 500m. The Delhi-class can also carry two Sea King choppers, primarily equipped with a Super Searcher radar for the air surveillance role. The choppers, equipped with super searcher radars, are capable of flying four and half hours non-stop. They are capable of both anti-submarine as well as anti-surface operations and can take off from the vessel within five to ten minutes. The INS Delhi has a crew of approximately 30 officers and 350 sailors.
