India has had thermonuclear weapons since 1998, atomic weapons since 1974, and Intercontinental Ballistic Missile capability since 2012.

The Indian nuclear program was started almost immediately after independance by nuclear physicist [[AwesomeMcCoolname Homi J. Bhabha]], but kept consistantly on the backburner by Prime Minister Nehru (due to his pacifist leanings) until his death in 1965, and thus India only developed its first device in 1974, as a tech demonstration. New Delhi did not immediately create an arsenal for lack of a delivery system and also for lack of wanting to cause alarm in the ColdWar environment going on at the time.

In 1983, India began their ballistic missile program, culimnating in the [[MeaningfulName Agni]] series of ballistic missiles. Agni I is an SRBM (short-range ballistic missile), while Agni II, III, and IV, are IRBMs (intermediate range ballistic missiles. The Agni V is India's first ICBM, though they are also developing the Agni VI and the Surya, which can go even further.

Also developed, with the Russians, is the nuclear-capable Brahmos cruise missile, currently the fastest cruise missile in the world.

Currently, India is developing submarine-launched ballistic missiles in order to complete its nuclear triad.

The name is in reference to the third eye of the Hindu god Shiva, which is said to lay utter destruction to all in its path should it ever open.
