• There are only 3 ‘Hypersonic Cruise missiles’ which are currently under development and soon going to be in service. Few countries like USA, United Kingdom, France etc have proposed the idea of a hypersonic cruise missile and this is still under their concept study and designs. For example, the ‘Perseus missile’ is still a concept study presented by MBDA in consultation with the Royal Navy and French Navy. Hence we do not include the Perseus missile in our list. The ‘Boeing X-51 Waverider’ too proposed by the Americans is still under research and also haven’t considered to be a cruise missile but rather a robotic technology demonstrator or a hypersonic test aircraft. The reason why the Shaurya missile is in the list is because it is classified as a ‘cruise missile hybrid system’. It is often confused whether it is clearly an ICBM. It flies like a ballistic missile till it attains the height of 50 km. Post that it behaves like a hypersonic cruise missile. The Shaurya missile has already done testing and is ready for production and induction into the Navy. Henceforth, there only three Hypersonic cruise missiles which are nearly to be in service. The list are: *Zircon missile *Shaurya missile *Brahmos II
