The BRAHMOS entered service with the Indian armed forces in 2006. This missile has been adopted by Indian Army, Navy and Air Force. Some sources report that Indian armed forces have a total requirement for about 1 000 of these missiles. This cruise missile is also being proposed for export customers from 14 countries.
The BRAHMOS is based on the Russian P-800 Oniks supersonic anti-ship cruise missile. The missile is 9 m long and has a diameter of 0.7 m. It has a two-stage propulsion system. It uses solid-fuel rocket booster for initial acceleration and liquid-fuel ramjet for sustained supersonic cruise. The booster is ejected by the airflow after it has burned out.
This missile has a range of 290-300 km. It can carry nuclear warhead, or 200-300 kg conventional warhead. The range is limited to 300 km, as Russia is a signatory of the Missile Technology Control Regime, which prohibits it from helping other countries develop missiles with ranges above 300 km.
The BRAHMOS is one of the fastest cruise missiles in the world. It travels at supersonic speed and can gain a speed of Mach 2.8 (3 430 km/h). This missile was developed primarily as an anti-ship missile, however there are also land attack versions. This cruise missile has GPS/GLONASS/GAGAN satellite guidance. It uses US, Russian or Indian navigation satellites and has a pin-point accuracy. At a maximum range it can hit a target as small as 1.5 x 1.5 m. It is a fire-and-forget type missile.
The BRAHMOS has the capability to engage targets from a very low altitude. It uses Russian sea-skimming cruise missile technology and can fly at altitude from 5 to 14 000 meters. Also it can maneuver at supersonic speed before hitting the target. Close-in weapon systems might not be effective against BRAHMOS, as it travels too fast. Also this missile can be used in electronic countermeasures environment. So it might be a hard nut for air defense systems to intercept.
BRAHMOS-A is an air-launched version. It is carried by fixed-wing aircraft. It is 9 m long and has a launched weight of 2 500 kg. It can be carried by an Indian Su-30MKI, however structural changes of the fuselage are required. The Indian Air Force has already adopted this cruise missile;
BRAHMOS-M another air-launched version. However this missile is smaller. It is 6 m long, but has the same range. It can be used by more Indian aircraft without modifications, such as, MiG-29K, Mirage 2000, and the Su-30MKI. As of 2015 this missile is still under development. It is expected to be adopted by 2017;
BRAHMOS II is a new hypersonic cruise missile, that is currently being developed by the BRAHMOS Aerospace joint venture. It is planned that the new missile will attain speed of up to Mach 7 (8 575 km/h). It is described as the fastest cruise missile in the world. It will have the same range as the BRAHMOS. It is expected to be ready for testing by 2017. Data military-today.com
BrahMos Block III
The BrahMos Block III is an advanced ground-launched, land attack, supersonic cruise missile fitted with a new guidance system and intended to destroy fortified/hardened targets and bunkers with high precision. The new missile also features deep penetration capability as well as extended range. The BrahMos Block III was first test fired from a mobile launcher by the Indian Army on November 18, 2013.
Diameter: 700 millimeter (27.6 inch)
Length: 9 meter (354 inch)
Wingspan: 1.70 meter
Max Range: 300 kilometer (162 nautical mile)
Cruise Speed: 2.80 mach (3,347 kph)
Warhead: 300 kilogram (661 pound)
Weight: 3,000 kilogram (6,614 pound)
Brahmos Missile Small-Size Version for Submarine: Details
Brahmos-NG is still faster than the PJ-10 (Mach 3.5 versus Mach 2.8) and has a longer range (more than 300 km/162 nm versus a maximum 290/157 nm km).
Moreover, the BrahMos-NG will have a newly developed AESA radar seeker in place of the mechanically scanned one on the PJ-10.
The Indian air force would benefit from adopting the Brahmos-NG, since three of them could be carried by its Su-30MKI multirole fighters, instead of one PJ-10. Besides, the aircraft would be able to land with one or two missiles on wing pylons, whereas landing safely with a standard missile attached to the center fuselage pylon is not possible.
