  • Russian military deployed a new intercontinental weapon, the Avangard hypersonic missile system that can fly 27 times the speed of sound.
  • Russia claimed that it is the only country in the world that has hypersonic weapons.

What is the Avangard hypersonic missile?

  • It is a reentry body carried atop an existing ballistic missile, which has the capability to manoeuvre.
  • Its manoeuvring capability makes it difficult to predict its trajectory and gives it the ability to protect itself from the air and ballistic missile defences by delivering nuclear warheads to targets, for instance, in Europe and the US.
  • The origins of the Avangard can be traced back to the mid-1980s, when Russia first started research on hypersonic warheads.
  • The Avangard missiles have a range of over 6,000 km, weigh approximately 2,000 kg and can withstand temperatures of over 2000 degree celsius.
  • Avangard can presumably reach speeds upto Mach 20 and can be used to deliver nuclear and conventional payloads.

What are Hypersonic Weapons?

  • Hypersonic weapons are the ones that can fly at speeds greater 5000 km/hr (more than 5 Mach).
  • These weapons fly low, remaining in the endo-atmospheric region (generally at altitudes below about 90 km), thereby reducing the chances of their detection by radar systems.
  • The hypersonic weapons have such speeds that can allow them to strike anywhere on the earth in under an hour.

Two Main Versions of Hypersonic Weapons

Currently two versions of hypersonic weapons are being developed.

Hypersonic Cruise Missiles (HCM)

It is a typical cruise missile which is ‘all the way powered’ to achieve hypersonic speeds of Mach 5 or higher.

Hypersonic Glide Vehicles (HGVs)

  • It is called a ‘wave-rider’ because it uses the shock waves generated by its own flight as a lifting surface to enhance the lift-to-drag ratio to reach the hypersonic regime of Mach 5 or even more.
  • It is launched by any solid propellant rocket/missile which can give it the initial boost and momentum up to a point after which the wave rider phenomenon can be sustained by the hypersonic vehicle on its own.

  • Geranium acts as an anti-inflammatory and anti-septic agent. It has several medicinal values.
  • The development has been made under Aroma Mission.
  • Reserve Bank directed large cooperative banks to report all exposures of Rs 5 crore and more to the Central Repository of Information on Large Credits (CRILC), a move aimed at early recognition of financial distress.
  • The Reserve Bank has created a CRILC of commercial banks, all India financial institutions and certain non-banking financial companies with multiple objectives, which, among others, include strengthening offsite supervision and early recognition of financial distress.
  • Earlier in its bi-monthly monetary policy, the RBI had decided to bring Primary (Urban) Co-operative Banks (UCBs) with assets of Rs 500 crore and above under the CRILC reporting framework.
  • To start with, UCBs will be required to submit CRILC report on quarterly basis with effect from December 31, 2019.
  • The First Trial Run of Double Stack Train was conducted on newly built Rewari-Madar section of Western Dedicated Freight Corridor (WDFC).
  • The Rewari-Madar section is in Haryana State (for approximately 79 Km in Mahendragarh & Rewari districts) and Rajasthan State (for approximately 227 Km in Jaipur, Ajmer, Sikar, Nagaur & Alwar districts).
  • Dedicated Freight Corridor Corporation India Limited (DFCCIL) will run freight trains at the maximum speed of 100 Kmph hour as against the current maximum speed of 75 kmph on Indian Railway tracks.
  • Average speed of freight trains will also be increased from existing speed of 26 kmph on Indian Railways lines to 70 kmph on Dedicated Freight Corridors (DFC).
  • Double-stack rail transport is a form of intermodal freight transport where railroad cars carry two layers of intermodal containers.
