the Indian armed forces by the early to mid 1990s. India was slow to develop the Agni missiles. It first tested the Agni technology demonstrator in 1989, the two-stage 2000 km range Agni-2 in 1999, single-stage 700 km range Agni-1 in 2001, the 3,000 km range three-stage Agni-3 in 2006, Agni-4 with a range of 4,000 km in 2011 and Agni-5 with a estimated range between 5,000 and 8,000 in the year 2012. The successor, Agni-6 is said to be under development with an speculated range of 10,000 km. Since India had a few nuclear weapons prior to the availability of these missiles, especially the Agni, it is probable that the current Indian nuclear weapons inventory includes weapons designed for delivery using airplanes. The Indian Armed Forces operates the Dassault Rafale which is capable of carrying out nuclear attacks. There are no open-source reports suggesting which if any of these planes have been equipped to deliver air-dropped atomic weapons. One or more of the following aircraft types might be used for this purpose. The MiG-27 and the Jaguar were originally designed to perform ground attack missions, and would require only modest modification to deliver nuclear weapons. The Indian Air Force also operates several other older and less capable types of ground-attack aircraft which would seem rather less likely candidates for delivering nuclear weapons. The MiG-29, Sukhoi Su-30 MKI and Mirage 2000 were originally designed to perform air-to-air combat missions, though they could potentially be modified to deliver air-dropped nuclear weapons. Plans are also on for the delivery of nuclear weapons via the Arihant class submarine using the SLBM/SLCM Sagarika.
