#1 Known in India as the father of the anti-ballistic air defense missile system, Vijay Kumar Saraswat began his career at the state-owned Defence Research and Development Organisation (DRDO) with the development of Indias first liquid-propulsion engine for the Prithvi missile.

Saraswat, who specializes in rocket propulsion, missile technologies, and project and technology management, today is the DRDOs chief controller for research and development. His future assignments include development of Indias anti-ballistic missile systems, radars, C4I systems and integration of battle management resources into a national authority. For his outstanding contribution to India, Saraswat was conferred with the Padma Shri Award, the countrys fourth-highest civilian award, in 1998.

Q. Please describe the homegrown ballistic missile defense system. How many missiles will it have for different layers of threats?

A. Our missile configuration is a three-layered missile defense configuration. We are planning to engage ballistic missiles at the exo-atmospheric layer, i.e., the layer where it enters the atmosphere, and the endo-atmospheric layer, where there is a thermally sensitive atmospheric layer. This configuration gives us the best probability of killing a ballistic missile coming to us. To increase hit probability, we can plan to launch two to three missiles each for exo- and endo-atmospheric.

The missile that demonstrates our capability to intercept ballistic missiles at exo-atmospheric altitudes is called PAD. It is a two-stage missile. The first stage is liquid, and the second is a solid rocket motor with many additional features, which are leading to an interception or engaging the ballistic missiles. For example, it has seeker guidance, divert thruster which can generate a lateral acceleration at more than 5 Gs at 50 kilometers altitude.

Q. How many missiles in the system?

A. There are two layers. At each battery there is a multiple launcher with multiple missiles.

Q. What is the configuration of BMD?

A. In a typical battery, you have the long-range radars, missile launchers, mission control center and other ground systems.

The complete network of radars, launch batteries, missile control centers, launch control centers. These are geographically distributed and are connected to a very potent secure communications network.

The radar is looking at a particular elevation and detects incoming ballistic missiles. This information is sent to the mission control center(MCC), which then decides whether it is a missile interceptor or a satellite or any other projectile, and it does target classification within a few seconds. When the target is classified, the MCC also calculates where the impact point of the target is likely to be and where it is going to fall.

After the target is classified, the MCC also finds out the trajectory profile and the speed it is going to travel. Based on that, it assigns a target to a particular battery. This is called target assignment.

Once the target is assigned, the data goes to a particular battery, then control goes to the launch control center (LCC). LCC keeps on getting data from radar directly, and then it decides when to launch the interceptor. This is decided based on the data received from radar, on the speed of target, altitude, flight path. A ground guidance computation is done. It's a very complex computation from ground computation when to launch the interceptor. All this is done in an autonomous fashion.

Q. Can you tell me the timeframe?

A. For the 600-kilometer class of system, if a radar has spotted a target, the interceptor will be launched within about 180 seconds. It will be different for 200-kilometer and 300-kilometer missiles.

Q. What is the speed of the air defense missile?

A. It is between 4.5 and 5 Mach. The same system has the capability to engage 300-kilometer to 2,000-kilometer classes of ballistic missiles.

Q. What is Phase II?

A. The same missile interceptors cannot cover all threats. Threat targets of longer ranges 2,000 kilometers will make our phase-II development.

During Phase I: Endo-atmospheric interceptor is AAD. This interceptor will engage targets at 25 kilometers. AAD is superior in terms of coverage area compared to PAC-3, which is 15 kilometers. You can see the difference. AADs equivalent is the Israeli Arrow, which intercepts at 40 kilometers. PAD is 50 to 80 kilometers. America is building a missile, THAAD Terminal High Altitude Area Defense that intercepts out to 120 kilometers, but it is still in development. Q. What is Phase II?

However, a lot of failures have taken place during THAAD development.

Q. What are the spinoffs?

A. Once Phase-II interceptors are developed, these can be used as long-range interceptors of aircraft at ranges of 120 kilometers.

You see the question which you asked that it has taken 20 years to develop. Now you see it is not taking more than 5 years - 6 years. Even Americans also take time. Their missile program with industrial infrastructure, the cost is very high and they take six to seven years before a missile is launched. This is also time taken for development of PAD and AAD.
