variants. The first test flight is expected to take place in 2022–24. Initially Brahmos-NG was referred to as Brahmos-M. Additionally, the BrahMos-NG will have an AESA radar rather than the mechanically scanned one on the BrahMos. The missile will arm the Sukhoi Su-30MKI, Mikoyan MiG-29K, HAL Tejas and future inductions such as the Dassault Rafale, and HAL MWF. Submarine launched variant will be capable of being fired from the new P75I class of submarines. A model of the new variant was showcased on 20 February 2013, at the 15th anniversary celebrations of BrahMos Corporations. The Sukhoi SU-30MKI would carry three missiles while other combat aircraft would carry one each. BrahMos Aerospace is planning to manufacture BrahMos-NG in Uttar Pradesh. The Indian Air Force already confirmed a requirement of 400 missile that will cost around ₹8,000 crore and be delivered within 5 years of time period. The missile is likely to be ready in late 2022. UCAV variant The former President of India, A. P. J. Abdul Kalam asked BrahMos Aerospace to develop an advanced version of the BrahMos cruise missile to maintain India's lead in the field. He stated that a hypersonic version of BrahMos would be needed that could deliver its payload and return to base. Specifications BrahMos has the capability of attacking surface targets by flying as low as five metres in altitude and the maximum altitude it can fly is 15,000 metres. It has a diameter of 70 cm and a wingspan of 1.7 m. It can gain a speed of Mach 3.5, and has a maximum range of 650 km. 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-fuelled 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. The high speed of the BrahMos likely gives it better target-penetration characteristics than lighter subsonic cruise-missiles, such as Tomahawk. Being twice as heavy and almost four times as fast as Tomahawk, the BrahMos has more than 32 times the on-cruise kinetic energy of a Tomahawk missile, although it carries only 3/5 the payload and a fraction of the range, which suggests that the missile was designed with a
