New Delhi, September 20: A website has claimed that among Edward Snowden’s leaked documents were some papers pertaining to United States’ espionage on India’s military installations. The documents say that US secret agency NSA had known that India was developing two types of ballistic missiles namely– Sagarika and Dhanush.


Sagarika is a nuclear-capable missile that can be launched from nuclear-powered submarines. They have a range of 750 kilometres. Its development was done by Indian scientists and the project was codenamed Project 420. It was completed in 2001 and was given to the Navy for testing. The missile tests were successful in 2008. It was tested to its full range several times and it struck its targets with accuracy. Now, it has entered production.


Dhanush is a variant of the surface-to-surface or ship-to-ship Prithvi 3 missile. It has been developed by the Indian Navy. Its range varies with the amount of payload mounted on it. It can carry convention and nuclear warheads as well. The missile can be used to destroy both land targets and ships.

Nuclear Triad

Nuclear triad means the capability to launch nuclear weapons from land, sea, and air. In case of a nuclear attack, the land and air modes of a retaliatory nuclear strike may be incapacitated. In that case, the only means remain is a strike from the sea. Since it is impossible to destroy all the submarines, they are the most important part of any country’s nuclear triad.
