In news- DRDO recently conducted the maiden flight test of the new version of Akash Missile, Akash Prime. 

About Akash Prime missile-

  • The Akash Prime is a medium-range mobile surface-to-air missile (SAM) system developed by the DRDO and produced by Bharat Dynamics Limited (BDL).
  • The Akash SAM was developed to replace the Russian 2K12 Kub (SA-6 Gainful) missile system, currently in service. 
  • The Akash SAM, like the Russian 2K12 Kub, utilizes an integrated ramjet-rocket propulsion system, which, after initial rocket motor burnout, provides sustained thrust for the missile throughout its flight until interception.
  • The missiles can be fired from a tank or a wheeled truck.
  • In comparison to the existing Akash system, Akash Prime is equipped with an improved active radio-frequency (RF) seeker to further increase the accuracy.
  • It is a more reliable performer under a low-temperature environment at higher altitudes.

About Akash Missile system

  • AKASH is a Short Range Surface to Air Missile system to protect vulnerable areas and vulnerable points from air attacks (25 Kms). 
  • The missile was inducted in 2014 in IAF and in 2015 in Indian Army. 
  • AKASH Weapon System can simultaneously engage Multiple Targets in Group Mode or Autonomous Mode. 
  • It has built in Electronic Counter-CounterMeasures (ECCM) features. 
  • The all-weather missile can engage targets at a speed 2.5 times more than the speed of sound and can detect and destroy targets flying at low, medium and high altitudes.

Akash uses a ramjet propulsion system which can intercept the target at supersonic speed without deceleration.

  • Ramjet, Scramjet and Dual Mode Ramjet (DMRJ) are the three air-breathing engine designs being developed by various space agencies that can use atmospheric oxygen during their travel through the atmosphere to significantly reduce overall propellant consumption.
  • A ramjet uses forward motion to compress incoming air for combustion without a rotating compressor.
  • Gas is pumped into the combustion chamber, mixing hot compressed air and igniting.
  • Ramjets operate most efficiently at supersonic speeds around Mach 3 (three times the sound speed) and up to Mach 6 speeds.
  • A scramjet engine is an improvement over the ramjet engine as it works effectively at hypersonic speeds, facilitating supersonic combustion. Hence it’s called Supersonic Combustion Ramjet, or Scramjet.
  • A dual mode ramjet (DMRJ) is a type of jet engine where a ramjet transforms into Mach 4-8 scramjet, which means it can operate efficiently in both subsonic and supersonic combustor modes.
  • It has been designed and developed as part of India’s Integrated Guided-missile Development Programme (IGMDP) which also includes other missiles like Nag, Agni, Trishul and Prithvi.
  • The missile has a launch weight of 720 kg, length of 5.8 m and a diameter of 350 mm and can carry a warhead of 50-60kg.
  • The nuclear-capable missile can fly at a speed of up to Mach 2.5 (nearly 860 meter per second) at a maximum height of 18 km. 
  • It can strike enemy aerial targets like fighter jets, drones, cruise missiles, air-to-surface missiles as well as ballistic missiles from a distance of 30 km.
  • The missile is supported by the indigenously developed radar called ‘Rajendra’ that can handle highly-manoeuvring multiple targets from multiple directions in group or autonomous mode.
  • The missile is reportedly cheaper and more accurate than US’ Patriot missiles due to its solid-fuel technology and high-tech radars.
