NEW DELHI: With active help from China and North Korea, Pakistan has surged well ahead of India in the missile arena. The only nuclear-capable
ballistic missile in India's arsenal which can be said to be 100% operational as of now is the short-range Prithvi missile.

Though the 700-km Agni-I and 2,000-km-plus Agni-II ballistic missiles are being "inducted" into the armed forces, it will take "some time" for them to become "fully-operational in the numbers required".

Defence sources said the armed forces were still in the process of undertaking the "training trials" of Agni-I and Agni-II to give them the requisite capabilities to fire them on their own.

Of the two, the progress report of Agni-I, tested for the first time in January 2002 to plug the operational gap between Prithvi (150-350 km) and Agni-II missiles, is much better. The Army has already conducted two "user training trials", one in October 2007 and other in March 2008, of the Pakistan-specific Agni-I missile.

The fourth test of 3,500-km Agni-III, which will give India the strategic capability to hit targets deep inside China, is also on the anvil now. But Agni-III, tested successfully only twice in April 2007 and May 2008, will not be ready for induction before 2012.

Then, of course, design work on India's most ambitious strategic missile with near ICBM (intercontinental ballistic missile) capabilities, the 5,000-km range Agni-V, which incorporates a third composite stage in the two-stage Agni-III, is also in progress. "We should be ready to test Agni-V by 2010-2011," said an official.

So, in effect, the missile report card is rather dismal at present. "Unlike Pakistan, our programme is indigenous. But a strategic missile needs to be tested 10 to 15 times, over a variety of flight envelopes and targets, before it can be said to be fully-operational. A missile cannot be dubbed ready just after three to four tests," said an expert.

Keeping this benchmark in mind, only Prithvi can be dubbed to be fully ready. Defence PSUs like Bharat Dynamics Ltd, Bharat Earth Movers Ltd and Mishra Dhatu Nigam Ltd, in fact, are stepping up production of the different Prithvi variants.

Army, for instance, has orders worth Rs 1,500 crore for 75 Prithvi-I and 62 Prithvi-II missiles, while IAF has gone in for 63 Prithvi-II missiles for over Rs 900 crore.

Navy, in turn, has ordered Dhanush missiles, the naval version of Prithvi, with a 350 km strike range, for its "dual-tasked" warships, INS Subhadra and INS Suvarna.

India wants to gatecrash into the very exclusive club of `Big-Five' countries like Russia, US and China, which have both ICBMs (missiles with strike ranges over 5,500-km) and SLBMs (submarine-launched ballistic missiles), before 2015.

The SLBM quest is specifically crucial since it's the most effective and secure leg of the "nuclear weapon triad", with land-based missiles and aircraft capable of delivering nuclear bombs constituting the first two components.

The initial range of K-15 SLBM being developed by DRDO will, however, be limited to 750-km, far less than the over 5,000-km range SLBMs brandished by the `Big-5' countries.

The plan is to go for higher strike ranges after the initial K-15 missiles are integrated into the indigenous nuclear-powered submarines being built under the secretive ATV (advanced technology vessel) programme.
