Nag anti-tank missile back in reckoning

-

Eighteen years after it was first tested, the meandering saga of the indigenous Nag anti-tank guided missile (ATGM) is finally entering the climax phase after an expenditure of over Rs 300 crore.

Or so it seems, with Defence Research and Development Organisation planning the "final developmental flight trials" of Nag at Pokhran on July 27-28, which will be followed by the "user-trials" in mid-September, say sources.

Having placed an order for 443 Nag missiles and 13 Namicas (Nag missile tracked carriers) for induction over three years, the Army is keeping its fingers firmly crossed.

The urgent need for ATGMs can be gauged from the fact that after ordering 4,000 Konkurs-M missiles, the Army is now looking for 4,100 "advanced" ATGMs with tandem warheads for "better kill probability" of enemy tanks.

The Army, in fact, has agreed to reframe its GSQRs (general staff qualitative requirements) for the 4,100 new missiles - by reducing its "essential" strike range from 2,000 metres to 1,850 metres - to enable defence PSU Bharat Dynamics Ltd (BDL) to participate in the programme.

BDL, incidentally, manufactures variants of the second-generation 2-km-range "Milan" and 4-km-range "Konkurs" ATGMs, under licence from French and Russian companies, at around Rs 4.50 lakh per unit.

The third-generation Nag missile, with a four-km strike range, will also be manufactured by BDL. But there is many a slip between the cup and the lip.

Over 60 developmental trials of Nag have been conducted over the years but recurring problems in the guidance systems, especially in the "imaging infra-red (IIR) sensor-based seeker", has meant the missile is still to become fully operational. DRDO, however, is quite confident now, holding that Nag will be among the world's most advanced ATGMs, better than other contemporary missiles like Israeli 2.5-km Gill and four-km Spike missiles.

"The Army has already accepted the Nag, which has fire-and-forget, day-and-night and top-attack (the missile pops up and hits the tank's vulnerable upper portion like the gun-turret) capabilities," said a DRDO official. "There have been delays due to import embargoes, problems in development of the IIR seeker, change in NAMICA configurations and the like. But Nag, which also has high immunity to counter-measures, is fully-ready now," he added.

Apart from the NAMICA platform, that can carry 12 missiles, Nag will also have an airborne version named "Helina" to be fitted on the Dhruv Advanced Light Helicopter, which will be configured to carry eight missiles in two launchers.

Incidentally, Nag was one of the "core missile systems" of the country's original Integrated Guided Missile Development Programme (IGMDP), launched as far back as in 1983. Announcing the IGMDP's "virtual closure" earlier this year, DRDO declared that development work on all other missiles - Agni, Prithvi, Akash and Trishul - had been completed.

Though work on "strategic" long-range nuclear-capable missiles like Agni-III (3,500-km range) and Agni-V (over 5,000-km) will still be "undertaken in-house", India will also look at foreign collaboration in other armament projects to cut down on delays.

Indigenous tank T-90 Bhishma rolls out

-
Image
The first batch of the indigenously built T-90 Bhishma tanks was on Monday (August 24) flagged off by Minister of State for Defence MM Pallam Raju at the rolling out ceremony held at the Heavy Vehicles Factory, Avadi, in Chennai. The T-90S tank incorporates many new technologies in terms of mobility, protection, fighting capabilities, safety and communication. The tank is equipped with 125mm smooth bore gun stabilised in Elevation and Azimuth, 12.7mm anti-craft machine gun and 7.62mm co-axial machine gun supported with high accuracy sighting systems and Automatic Loader ensuring high rate of fire. A significant feature of this tank is its capability to fire guided missile in addition to conventional ammunition using the same main gun barrel. The integrated fire control system consisting of the gunner’s sight, guided weapon system and ballistic computer facilitates accurate firing of conventional ammunitions as well as the guided missiles. The built in Explosive Reactive Arm

Second only to US IAF & Navy to get DRDO's CHAFF tech for protecting Aircrafts and Ships from enemy missile

-

The Indian Air Force and Navy have partnered with the Defence Research and Development Organisation to acquire the CHAFF technology, which protects warships from anti-ship missiles during combat. After the United States, India is now the second country to develop this capability, signalling a major Aatmanirbhar push in the field of defence. The development is significant because the Indian navy is investigating the sinking of the Russian missile cruiser Moskva and concentrating on how to protect our warships from anti-ship ballistic missiles such as the Chinese DF-21. What exactly is CHAFF? CHAFF is a critical defence technology that protects fighter planes and naval ships from enemy radar-guided missiles during wartime. The importance of this technology stems from the fact that a small amount of CHAFF material deployed in the air acts as a decoy to deflect enemy missiles, ensuring the safety of fighter planes and naval ships. This advanced CHAFF technology was developed by the DRDO to

India built N-sub in Kalpakkam under codename 'PRP'

-
The secrecy attached to the development of the indigenous nuclear submarine project is almost legendary. What’s little known is the extent to which the Indian N-establishment went to conceal the research not only from the public but also large sections of the scientific community within the Department of Atomic Energy (DAE). For almost nine years, most staff working at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam believed the Plutonium Recycle Project (PRP) in the complex was used only for that purpose, that is recycling plutonium. But with the launch of INS Arihant on July 25, top DAE officials have finally begun to lift the veil and reveal that they were actually building the core (nuclear reactor and propulsion systems) of the submarine as well as the land-based version of the hull of the indigenous vessel, which served as the technology demonstrator of the main vessel, within the PRP unit. For those in the know, even the term ‘PRP’ denoted the N-sub.
