Solution:Statements 1 and 2 are correct with reference to Brah Mos missile.The missile has a flight range of up to 290 km with supersonic speed all through the flight, leading to shorter flight time, consequently ensuring lower dispersion of targets, quicker engagement time and non-interception by any known weapon system in the world.
The BrahMos is a Ramjet Supersonic cruise missile of a short-range developed by DRDO and the Russian Federation's NPOM. It can attain a speed of MACH 2.8 to MACH 3 and can be upgraded to the speed of MACH 5 (Hypersonic).
Statement 3 is incorrect.
It operates on 'Fire and Forget Principle', adopting varieties of flights on its way to the target. Its destructive power is enhanced due to large kinetic energy on impact. Its cruising altitude could be up to 15 km and terminal altitude is as low as 10 metres. It carries a conventional warhead weighing 200 to 300 kg.
