The BrahMos is a medium-range ramjet supersonic cruise missile that can be launched from submarines, ships, fighter aircraft or TEL. It is a joint venture between the Indian Defence Research and Development Organisation (DRDO) and the Russian Federation's NPO Mashinostroyeniya, who together have formed BrahMos Aerospace. The missile is based on P-800 Oniks. The name BrahMos is a portmanteau formed from the names of two rivers, the Brahmaputra of India and the Moskva of Russia.

BrahMos-II or BrahMos-2 or BrahMos Mark II is a hypersonic scramjet-propelled missile currently under joint development by India's Defence Research and Development Organisation and Russia's NPO Mashinostroyenia, which have together formed BrahMos Aerospace Private Limited. The BrahMos-II is expected to have a range of 1,500 kilometres and a speed of Mach 8. During the cruise stage of flight, the missile will be propelled by a scramjet airbreathing jet engine. Other details, including production cost and physical dimensions of the missile, are yet to be published.
