Zircon Hypersonic Cruise Missile

In News 

  • Recently, Russia had carried out another successful test of its Zircon hypersonic cruise missile from the Severodvinsk submarine and hit a designated mock target in the Barents Sea.

About Zircon hypersonic cruise missile

  • Zircon’s tests are to be completed later this year and they will be commissioned by the Russian navy in 2022.
  • It could hit targets at sea and on land with a range of 1,000 kilometres (620 miles).
  • It would be capable of flying at nine times the speed of sound.
  • Zircon is intended to arm Russian cruisers, frigates and submarines.
  •  It is one of several hypersonic missiles under development in Russia.

Developments in India

  • India has collaborated with Russia on the development of BrahMos II, a Mach 7 hypersonic cruise missile.
    • BrahMos II was initially intended to be fielded in 2017 but the programme faces significant delays and is now scheduled to achieve initial operational capability between 2025 and 2028.
  • India is also developing an indigenous, dual-capable hypersonic cruise missile as part of its Hypersonic Technology Demonstrator Vehicle programme and successfully tested a Mach 6 scramjet in June 2019 and September 2020.
  • India operates approximately 12 hypersonic wind tunnels and is capable of testing speeds of up to Mach 13.

What is Hypersonics?

  • Hypersonics can travel more than five times the speed of sound and manoeuvre in mid-flight, making them much harder to track and intercept than traditional projectiles.
  • The combination of speed, manoeuvrability and altitude of hypersonic missiles, capable of travelling at more than five times the speed of sound, makes them difficult to track and intercept.
