Agni-II
(詳細はAgni-IV plugging the gap between Agni-II and Agni-III. While the first test of Agni-IV in December 2010 was a failure, the second test flight in November 2011 was a success Agni-II, developed as part of medium and long range Agni series of missile systems, has already been inducted into the Armed Forces.〔
On 17 May 2010, the trial was conducted with a special strategic command force (SSC) of nuclear-capable Agni-II ballistic missile, with a range of 2,000 kilometres from the Wheelers Island off Orissa coast thus making Agni-II missile operational by army. The missiles are operated by the 335 Missile Group at Secunderabad using 12 TEL vehicles.
== Preface: Evolving Indian Security Environment ==
During the 1990s, India's security situation gradually worsened with security challenges from China, blatant Chinese nuclear and missiles proliferation to Pakistan, and mutual proliferation between Pakistan and North Korea. The strategic redline was crossed in 1998 when Pakistan tested nuclear capable Ghauri missile, that could threaten India's heartland. The international complicity in allowing nuclear proliferation by proxy into the hands of Pakistan and ability to deliver it over long ranges, obtained by trading in black-market North Korean No-Dong missiles, in return for Pakistani nuclear design and enrichment equipment by the nuclear and missile black-market run by Pakistani scientist A.Q. Khan and the Pakistani Military. These developments forced India to go fully nuclear, resulting in the Pokhran-II nuclear test series and its weaponisation by developing the Agni family of ballistic missiles that could deliver a variety of payloads over long ranges.
Quick deployment of the Agni-II was possible, by building on the earlier Agni-TD program that provided proven critical technologies and designs required for long range ballistic missiles. Thus when the decision was made to build the Agni weapon system, some quick optimisation and ruggedisation was done to the basic '1980 vintage' design, including a solid fuelled second stage. The re-entry vehicle (RV) and avionics were brought up to state-of-the-art levels. The Pokhran-II nuclear test proved a family of more powerful and lighter nuclear weapons; the 200 kt thermonuclear weapon is far lighter compared to 1,000 kg earlier budgeted for the 200 kt boosted nuclear weapon. Thus a high yield weapon configuration now assumes a payload of 500 kg, including weapon and RV. However, in the interest of rapid development, the basic design that was earlier developed continued to be used, keeping the future option open for more optimised missile design and lighter payload.
