Indra 2018: Tri-service joint India-Russia military exercise to be conducted in India

The tri-service joint military exercise Indra-2018 between India and Russia will take place at Indian military base in second half 2018. In this regard, Russian military delegation visited India to discuss logistics of the exercise.

In this edition of exercise, combined military units of Russian Eastern Military District will participate in military drills. Members of Indian defence forces were also involved in planning of the exercise which included practical operations of units besides consumer services, catering and medical support for Russian units. In addition, they also agreed on procedure for receiving and servicing of military transport aircraft in India.


INDRA military exercise was launched in 2003 as bilateral exercise between India and Russia to boost cooperation and interoperability between navies of two countries. The name of the exercise INDRA has been derived from INDia and RussiA. Till 2016, the bilateral exercises under INDRA were undertaken between respective Armies, Navies and Air Forces of India and Russia by separately engaging with each other without concurrent participation from other services. This exercise was transformed into tri-services military exercise in 2017 and was for first time held successfully in October 2017 at Vladivostok, Russia. It was India’s first joint tri-services exercise and also first between Russia and India. It was also first time Russia has hosted tri-services military exercise on its soil.


Maiden test Next Generation SFDR Air to Air Missile successfully conducted

The Defence Research and Development Organisation (DRDO) successfully carried out maiden flight test new surface-to-air missile (yet to get formal name) powered by Solid Fuel Ducted Ramjet (SFDR) propulsion Technology. The test also successfully demonstrated technology of nozzle less booster for first time in the country.

About Test

SFDR’s technology demonstrator flight test was conducted from Launch Centre-III of Integrated Test Range at Chandipur, Odisha. The defensive missile flew in its intended trajectory at speed of Mach 3 (thrice the speed of sound) and met all mission objectives.


SFDR technology is jointly developed by India and Russia. It will help both India’s surface-to-air and air-to-air missiles to perform better and enhance their strike range, making them more lethal. With it, India can have fastest long-range missiles in two categories, providing full-fledged and multi-layered aerial protection from hostile attacks.  Its successful use in missiles will mark India’s entry into select club of nations that use next-generation missile technology against maneuvering targets, compromising effectiveness of conventional missiles.

Difference between SFDR and Conventional Missiles

SFDR is propulsion technology different than that of conventional solid fuelled or liquid fuelled missiles. Present lot of conventional missiles uses booster or sustainer configuration with solid or liquid propellants, which have limitations against maneuvering target. This is because terminal stage of conventional missiles cannot provide enough energy to maintain their speed in order to hit targets. SDFR technology removes this drawback by exceptionally enhancing endgame maneuverability of missile at terminal stage when its seeker is locked onto target.
