check out the damage the missile does to the ships even with a dummy warhead.
The small ship shown blown up and sinking at 3:57-4:00 is the ex-IN Durg (Nanushka) class corvette- INS Sindhudurg K72

The big ship at 2:17 with a hole in the side (caused by a dummy warhead) and 2:58 (I guess with a conventional warhead) is the ex-IN PETYA class frigate - INS Arnala P68 or INS Androth P69!!
Enjoy!

Though they are meant for same roles, BrahMos is unique in several aspects,

*BrahMos travels at speeds of Mach 2.5 to 2.8 and is the world's fastest cruise missile. It is about three-and-a-half times faster than the U.S.A's subsonic Harpoon cruise missile.

*The high speed of the BrahMos likely gives it better target-penetration characteristics than lighter subsonic cruise-missiles such as the Tomahawk. Being twice as heavy and almost four times faster than the Tomahawk, the BrahMos has almost 32 times the initial kinetic energy of a Tomahawk missile (which is similar to Babur Cruise Missile).

Just wait for the Hypersonic version of BrahMos, its said to have longer range and higher speed ( lab tested with a speed of 5.26 Mach) !
