The DRDO Puts Out A Glowing 'Year Gone By'

03.01.2015 source Livefist

Here's all the good stuff DRDO did in 2014 packed into one glowing self-assessment. Some interesting data and nuggets if you've got the patience to sift through it. For instance, this is the first public official document to state the range class of the Nirbhay cruise missile. Text in full:

With increasing numbers of military systems indigenously designed and developed for the Indian armed forces being produced by Indian industries, the Defence Research and Development Organization (DRDO) continued on a path of building self-reliance. About 55% of the requirements for our defence forces are being met indigenously, largely with the technologies developed by DRDO, contributing greatly to nation’s economy. The production value of DRDO developed systems inducted or cleared for acquisition (excluding strategic systems) crossed Rs 1,70,000 crore.


The year 2014 witnessed yet another series of accomplishments with enormous potential to further enhance the level of self-reliance in defence technologies.




The 4000 km range road mobile nuclear capable ballistic missile AGNI-4, was successfully flight tested twice. The flight on 20th January, last among the development flights paved the way for flight on December 2 by the armed forces. Agni 4 is equipped with state of the art Avionics, 5th generation On Board Computer and distributed architecture. The missile is equipped with latest features to correct and guide it for in-flight disturbances. Its highly advanced Inertial Navigation System ensures high accuracy. It’s re-entry heat shield, capable of withstanding high temperatures that may reach as high as 4000 degree centigrade and above during reentry of missile in earth’s atmosphere, makes sure that the inside temperature remain less than 50 degree centigrade.


With Agni 1, 2, 3 and Prithvi already in India’s arsenal, Agni 4 further extends the reach and enhances effective deterrence capability. Besides, practice cum training launches of strategic missiles already inducted, such as Agni-1, Agni-2, P-II and Dhanush were carried out by armed forces.


Nirbhay, the 1000-km class long range sub-sonic cruise missile was successfully flight tested on the 17th October 2014. The flight lasted for over one hour and met all the mission objectives with missile following the predefined trajectory with very high accuracy throughout its path.


Maiden flight of PDV exo-atmospheric interceptor on 27th April 2014 was a significant milestone in the direction of developing a two layered Ballistic Missile Defence system. In addition to the interceptor itself, the two stage target for mimicking a "hostile Ballistic Missile approaching from more than 2000 km away" too was specially developed for the mission.


Productionisation and induction of Akash, the medium range air defence system with multi-target, multi directional capability was another remarkable achievement. Several squadrons of Akash (AF) have been inducted, with specified number of missiles from each production lot undergoing comprehensive flight tests in various operational modes before acceptance of the lot. Akash (army) has been accepted and is undergoing induction process. LRSAM, the long range surface to air missile was successfully tested against a flying target in Israel on 10 Nov 2014.


Successful trials of Helina, a “lock- on before Launch (Fire & Forget)” third generation Antitank Guided missile that can attack in both direct and top attack mode was integrated with advanced light helicopter (ALH). The missile with capability to defeat futuristic armors underwent successful field trials on 27th Jun 2014.


ASTRA-BVR (Beyond Visual Range) air-to-air missiles was successfully tested from a Su-30MKI by the Indian Air Force, demonstrating interception of an electronically simulated target at long range. The series of tests conducted have demonstrated the aerodynamic characteristics of the missiles and its repeatability, robustness and endurance capability as a weapon system.


A 1000-kg class guided glide bomb was designed developed and successfully tested. The bomb, after getting released by the aircraft and guided by onboard navigation system is capable of gliding accurately to its target even 100 km away.


Over thirty missions such as launches of strategic and tactical guided missiles kept the Integrated Test Range, the only one in the country, heavily engaged with activities throughout the year.


A four km long Rail Track Rocket Sled (RTRS) Penta Rail Supersonic Track, a national test facility was established and made operational bringing India among a handful of countries in the world now possessing this unique test facility. The RTRS will facilitate testing and evaluation of a wide range of critical systems such as payload for manned missions of ISRO, the navigation system for missiles and aircrafts, proximity fuses for advanced warheads, fuses for armament systems parachutes for payload delivery, arrester systems for aircraft such as LCA.


Even as the total number of flights of all the LCAs put together crossed 2800 mark, The Light Combat Aircraft -LCA program witnessed yet another milestone on November 8 when Tejas trainer PV6, the two-seater version of Tejas LCA for Air Force, in its first flight took to the skies and became the 16th Tejas variant to have flown as part of the program. Having absorbed all the major design modifications undertaken during the flights of earlier aircrafts PV6 is the final prototype leading to series production of trainer and has the capability to deliver all ‘air-to-air’ and ‘air-to-ground’ weapons deliverable by the single seat counterpart.


In another landmark event, LCA (Navy) Prototype 1 (NP1), the first indigenously designed and developed 4th plus generation combat aircraft designed to operate from the decks of air-craft carriers, took-off majestically from ski-jump facility of Shore Based Test Facility at INS Hansa in Goa on 20th December. The special flight control law mode of LCA-Navy allows hands-free take-off from the ramp and automatically puts the aircraft in an ascending trajectory. It is designed with stronger landing gears to absorb forces exerted by the ski jump ramp during take-off, to be airborne within 200 m as against 1000m required for normal runways. The Shore Based Test Facility (SBTF) created to replicate the aircraft carrier with a Ski Jump for take-off and arresting gear cable for arrested landing, became operational for R&D as well as pilot training.


Two AEW&C aircraft having fitted with the indigenous radars and other equipment such as data links, mission system controller, data handling and display system; have been flying. A wheeled version of Nishant UAV named Panchi has been realized and had it’s maiden flight on Dec 24 after series of high speed taxi trials.
