Explanation:

The range of the land-attack version of the BrahMos missile has been extended to 400 km from the original 290 km but its speed has been maintained at 2.8 Mach or almost three times the speed of sound.

• The test was done in a “top-attack” configuration.
• In top attack mode, the missile is required to climb sharply after launch, travel at a certain altitude and then fall on top of the target.

An amalgamation of the names of Brahmaputra river and Moskva river (Russia), BrahMos missiles are designed, developed and produced by BrahMos Aerospace. BrahMos Aerospace is a joint venture company set up by the Defence Research and Development Organisation (DRDO) and Mashinostroyenia of Russia.

• It is a medium-range supersonic cruise missile which can be launched from submarines, ships, aircraft or land.
• Cruise missiles are defined as “an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target.”
• It is the world’s fastest supersonic cruise missile, as well as the fastest anti-ship cruise missile in operation.
• It operates on the “Fire and Forget” principle, i.e it does not require further guidance after launch.
• The missile has a flight range upto 290-km. However, India’s entry into the Missile Technology Control Regime (MTCR) has extended the range of the BrahMos missile to reach 450-600 km.

Hence both statements are correct.
