Supersonic Cruise Missile

One of the significant technological breakthroughs of 2005 is the design, development and productionization of Supersonic Cruise Missile - BRAHMOS by an Indo-Russian joint venture. Today Brahmos is the first supersonic operational cruise missile in the world, which can be launched from multiple platforms such as ships, submarines, road mobile and silo, and with modifications from aircraft. This is indeed the result of technological co-operation resulting into operational system. The supersonic speed is achieved by a liquid ramjet engine and the guidance is achieved through powerful software embedded in the on-board avionics integrated with high performance sensors. The fast response Inertial guidance system and agile homing head enables the missile to achieve variety of trajectories flying at speed Mach 2.8 and destroy the target with high accuracy. The flight trajectories are simulated through a modular, digital and fully automated Fire Control System, which has advanced software for way point maneuvering, with supersonic maneuvering to provide high operational capabilities. This technological innovation is the trendsetter in the cruise missile field. The robust design of the missile, elaborate ground tests and simulation has ensured 100 percent success rate in all the flight tests conducted for the Armed Forces who have accepted the system for induction. This unique cruise missile can be launched at any angle from horizontal to vertical mode and has 3600 azimuth coverage.

Realization of such a state-of-the-art missile system in less than five years has been possible due to intensive technological co-operation and strength of the Joint Venture partners. The unique feature of the BRAHMOS are - high level of reliability, ease of operation, ability to conduct multiple launches simultaneously against multiple targets, long shelf life with minimum maintenance, meeting multi-service requirements from multiple platforms against different targets and automation with advanced software. In successful design, development, production and marketing of BRAHMOS missile, a new way of technology co-operation has emerged between India and other countries. BRAHMOS has put India in the world map by defence scientists
BrahMos is a supersonic cruise missile that can be launched from submarines, ships, aircraft or land. It is a joint venture between India's Defense Research and Development Organization (DRDO) and Russia's NPO Mashinostroeyenia who have together formed the BrahMos Aerospace Private Limited.

The acronym BrahMos is perceived as the confluence of the two nations represented by two great rivers, the Brahmaputra of India and the Moskva of Russia. At speeds of Mach 2.5 to 2.8, it is one of the world's fastest cruise missiles and is about three and a half times faster than the U.S.A's subsonic Harpoon cruise missile. A hypersonic version of the missile is also presently under development (Lab Tested with 5.26 Mach Speed).[2]

Though India had wanted the BrahMos to be based on a mid range cruise missile, namely P-700 Granit, instead Russia opted for the shorter range sister of the missile, P-800 Oniks, in order to comply with MTCR restrictions, to which Russia is a signatory. Its propulsion is based on the Russian Yakhont missile, and guidance has been developed by BrahMos Corp.
Development and Manufacture

The BrahMos has been developed as a joint venture between the Defence Research and Development Organization (DRDO) of India and the Federal State Unitary Enterprise NPO Mashinostroyenia (NPOM) of Russia under BrahMos Aerospace. The missile is named after two rivers, the Brahmaputra and the Moskva.

Since late 2004, the missile has undergone several tests from variety of platforms including a land based test from Pokhran desert, in which the 'S' maneuver at Mach 2.8 was demonstrated for the Indian Army and a launch in which the land attack capability from sea was demonstrated.[3]

BrahMos claims to have the capability of attacking surface targets as low as 10 meters in altitude. It can gain a speed of Mach 2.8, and has a maximum range of 290 km.[1] The ship-launched and land-based missiles can carry a 200 kg warhead, whereas the aircraft-launched variant (BrahMos A) can carry a 300 kg warhead. It has a two-stage propulsion system, with a solid-propellant rocket for initial acceleration and a liquid-fueled ramjet responsible for sustained supersonic cruise. Air-breathing ramjet propulsion is much more fuel-efficient than rocket propulsion, giving the BrahMos a longer range than a pure rocket-powered missile would achieve.[citation needed]

The high speed of the BrahMos likely gives it better target-penetration characteristics than lighter subsonic cruise-missiles such as the Tomahawk.[4] Being twice as heavy and almost four times faster than the Tomahawk, the BrahMos has almost 32 times the initial kinetic energy of a Tomahawk missile (although it pays for this by having only 3/5 the payload and a fraction of the range despite weighing twice as much, suggesting a different tactical paradigm to achieve the objective).

Although BrahMos is primarily an anti-ship missile, it can also engage land based targets. It can be launched either in a vertical or inclined position and is capable of covering targets over a 360 degree horizon. The BrahMos missile has an identical configuration for land, sea, and sub-sea platforms. The air-launched version has a smaller booster and additional tail fins for added stability during launch. The BrahMos is currently being configured for aerial deployment with the Su-30MKI as its carrier.
