    The battle for Chandipur range


    NEW DELHI: The DRDO and Orissa Government are at odds over renewal of the lease of the former’s missile and gun testing site in and around Chandipur. The Orissa government has been refusing to issue a fresh notification, contending it intends to develop four ports between Paradip and Dhamra along the eastern coastline.

    Since its establishment, Chandipur has been considered a precious test range of pre- and post-Independence India. It played a significant role in the two world wars. A number of test vehicles of different classes, including multi-role missile Trishul, multi-target capability missile Akash, the anti-tank Nag missile, the surface-to-surface missile Prithvi and the Agni-I large scale technology demonstrator have been test-fired from this range. The ITR has also supported a number of other missions such as Multi-barrel Rocket Launcher Pinaka and Pilotless Target Aircraft (PTA).

    With the state government refusing to budge, the defence ministry immediately dispatched Scientific Advisor to the Defence Minister and DRDO chief V K Saraswat to discuss the matter with the Orissa Chief Minister. “In a lengthy meeting, Saraswat tried to impress upon the state government that it is not possible to shift the missile testing range from Chandipur. He also explained that the proposed four ports would lead to hectic commercial activity along the coastline, making testing difficult from Wheeler Island and Chandipur,” sources added. Saraswat suggested that the ports should not come up and that a fresh notification should be issued soon. There has been no word yet from the state government.

    DRDO has established elaborate infrastructure at the range with a number of tracking instruments being deployed to cover the total flight path of the test vehicles. The ongoing tussle between the Orissa government and the ministry could prove costly for the rocket development programme as DRDO plans to develop a rocket with 70-km range.


    DRDO would be requiring more area to test rockets with longer range. But this new development can put the project in limbo,” the sources added.

    This is interesting:

    The Tribune, Chandigarh, India - Nation

    Chandigarh, November 15
    Explosives meant to kill and destroy but being designed to minimise damage to the environment without compromising upon their lethality sounds strange. Yet this is what the scientific community is now seriously contemplating.

    Being referred to “green explosives”, these bombs, and also propellants for missiles and rockets, would be using ingredients that release lesser toxic elements than the emissions of chemical compositions being used at present.

    The Defence Research and Development Organisation (DRDO) has also initiated work on developing eco-friendly explosives and propellants. “We are also looking to collaborate with some friendly countries in this arena,” a senior scientist who attended the High Energy Materials Conference and Exhibits at DRDO’s Terminal Ballistics Research Laboratory here said. “The United Kingdom, Ukraine, Germany and Russia are among the prospective partners,” he added.

    According to defence scientists, the fallout of a chemical explosion does not merely end with the detonation, but the adverse effects of the chemicals continue to linger on in the environment for a long time. This not only affects the atmosphere, but also the ground soil and its organic and inorganic constituents, including agricultural-friendly organisms in the vicinity of the blast site. Similarly, rocket engines emit a huge amount of toxic gases and other elements during combustion and their flight through the atmosphere.

    “Among the options we are exploring is to avoid the use of certain aluminum-based compounds in rocket propellants. Similarly lead compounds in explosives can be replaced,” Dr A. Shubhanand Rao, Chief Controller, DRDO said. “Also, we are studying methodologies to safely dispose-off such toxic materials, where their use if inevitable, through processes known as green-synthesis,” he added.

    DRDO’s High Energy Materials Research Laboratory (HEMRL) is the nodal agency for research and development of explosive materials. It has recently developed CL-20, being claimed as the world’s most powerful convectional explosive. Dr Rao said CL-20 is about 30 per cent more powerful than the RDX. It is now being produced by a private firm, but is an expensive material costing over Rs 70,000 per kg.

    Seriously wtf? What kind of prioritization matrix does DRDO work against? This is bull. Spend that money on speeding up other critical research.
