Explanation:

Both 1 and 2

• BrahMos-armed Su-30MKI would be a game changer in the Indian Ocean, giving the IAF a deeper strategic reach and an extra deadly punch. With a range of 290 km, the missile will allow the pilot to hit enemy vessels while staying well outside the reach of their air defences. Travelling at a top speed of Mach 2.8 barely 3-4 metres above the sea surface, the missile cannot be intercepted by any known weapon system in the world.
• BrahMos Aerospace, a joint venture between India and Russia, has started designing a hypersonic version of the BrahMos missile, BrahMos–II.

Hence both statements are correct.
