Modified Indian combat jet to test-fire supersonic missile

Country will be only the second Asian nation, after China, capable of delivering a cruise missile from the air

They are both of Russian origin and are made in India. Some time next year, a modified combat jet will testfire a supersonic cruise missile in what will amount to a quantum leap in the firepower of the Indian Air Force (IAF).

This will also make the BrahMos nuclear-capable short-range missile, a joint project between India’s Defence Research and Development Organisation (DRDO) and Russia’s Federal State Unitary Enterprise NPO Mashinostroyenia (NPOM), capable of being operated from land, sea and air.

India will be only the second Asian country, after China, capable of delivering a cruise missile from the air.

According to a defence ministry official, one front line Sukhoi Su-30MKI combat jet, the most potent in the IAF’s inventory, has already been upgraded for being armed with the BrahMos missile, which has a range of around 300km and flies at a speed of Mach 2.8 — almost thrice the speed of sound.

Hardened circuitry

Another aircraft is also being upgraded and is likely to be delivered in the first quarter of 2016, the official, who spoke on strict condition of anonymity, said. The fighter’s aerodynamic configuration increases its effectiveness and allows a high angle of attack manoeuvres. The integral aerodynamic configuration, combined with thrust vectoring, gives it practically unlimited manoeuvrability and unique taking off and landing characteristics.

According to sources, the modification to the fighter includes hardened electronic circuitry to shield this from the electromagnetic pulse of a nuclear blast.

Along with the aircraft, the missile — whose airframe is built of titanium and highstrength aluminium alloys, giving it a high-speed terrain-following profile — was also modified with a reduced booster and fins for stability. It can be released from a height of 14,000 metres to 500 metres. After release, the missile freefalls for 100-150 metres, then goes into a cruise phase and finally the terminal phase at 15 metres from the target.

The airborne version of the missile is also lighter than its sea and land counterparts.

An official said a decision on arming other IAF jets with the BrahMos will be taken after the Su-30 tests are done with. However, there is some talk of developing a smaller version of the BrahMos for the Rafale, 36 of which are being bought from France, and the Indian Navy’s carrier-borne MiG-29s.
