The work to integrate the Brahmos supersonic cruise missile on 40 Sukhoi combat aircraft has begun and a timeline for the project is being set, official sources said.
"The work is expected to be completed by 2020 and will fulfil the needs of the Indian Air Force," UNI cited a source as saying.
The air-launched variant of Brahmos, the world's fastest supersonic cruise missile, was successfully test fired from a Sukhoi-30 combat jet on 22 November, marking a major milestone to enhance the precision strike capability of the Indian Air Force.
The fleet of 40 Sukhoi jet will undergo structural modifications at the state-run aerospace major Hindustan Aeronautics Ltd (HAL) for integration of the missile on them.
The 2.5-ton missile flies almost three times the speed of sound at Mach 2.8 and has a range of 290 km.
The range of the missile, an Indo-Russia joint venture, can be extended up to 400 km as certain technical restrictions were lifted after India became a full member of the Missile Technology Control Regime (MTCR) last year.
The Brahmos missile is the heaviest weapon to be deployed on India's Su-30 fighter aircraft.
Once the project to integrate the weapon on the combat fleet is completed over, the IAF capability to strike from large stand-off ranges on any target in sea or land is expected to go up manifold.
"It is a very important project considering IAF's evolving requirement to boost air power when the possibility of a two-front war cannot be ruled out," an official told PTI.
After the test firing of the air-launched version, the IAF had said the missile coupled with the superlative performance of the Su-30 aircraft will give the force a strategic reach and will allow it to dominate the ocean and the battle fields.
The integration of the missile on Sukhoi aircraft is a very complex process involving mechanical, electrical and software modifications of the Su-30 jet.
Brahmos is a joint venture between DRDO of India and NPO Mashinostroyenia (NPOM) of Russia.
