AKASH-1S Missile: test fired by DRDO

The Defence Research and Development Organisation (DRDO) successfully test fired Akash-1S surface to air defence missile system from Integrated Test Range (ITR) in Balasore off the Odisha coast. This is the second successive successful missile test by DRDO in last two days.

About Akash-1S

Background:

  • The Akash missile is a medium range multi-target engagement capable missile that was developed as part of Integrated Guided-Missile Development Programme (IGMDP). Other missiles under IGDMP are Nag, Agni, Trishul, and Prithvi missiles. The missile system was formally inducted into the Army on May 2015 and in the IAF on July 2015. Later in September 2015 the Defence Acquisition Council (DAC) cleared seven additional squadrons of the Akash missile for IAF.
  • After a 2017 Comptroller and Auditor General (CAG) report stated that 30% of these missiles failed when tested and in 2017 itself the Army too agreed that missiles did not meet its operational requirements because of their higher reaction time.

Features

  • It is a supersonic surface to air missile with multi-target engagement capability.
  • Akash-1S is an upgrade version of existing Akash missile fitted with an indigenously developed seeker.
  • The new Akash weapon system has combination of both command guidance and active terminal seeker guidance.
  • Range: The missile has a range of about 25 km and altitude range of 18,000 metres (18km).
  • It is capable of neutralizing advanced aerial targets and in striking down enemy fighter jets and drones effectively.
  • Missile system uses: high-energy solid propellant for booster and ramjet-rocket propulsion for sustainer phase thus is said to be highly mobile.
  • Variants: include Akash MK1, Akash-MK2. They have improved accuracy and higher ranges are under development by the DRDO.

Way Forward

  • India taking certain steps to slowly fill the holes in its air defence elements such as by developing advanced surface-to-air missile called ‘Medium Range Surface to Air Missile’ (MRSAM) in collaboration with Israel.
  • Besides MRSAM, India is also procuring five regiments of renowned S-400 air defence system from Russia whose delivery will begin in 2020.

BrahMos Air Launched Missile test fired from a Su-30 MKI

The Indian Air Force (IAF) successfully fired aerial version of supersonic BrahMos cruise missile from a Su-30 MKI fighter aircraft.

Key Highlights

  • About: The IAF successfully fired BrahMos Air Launched Missile from its frontline Su-30 MKI fighter aircraft.
  • Background: Earlier on 22 November 2017, the IAF became World’s first Air Force to successfully fire an air launched 2.8 Mach surface attack missile of this category on a sea target. Since then this was the second such live launch of weapon.
  • Result: The launch from Su-30 MKI aircraft was smooth and missile followed desired calculated trajectory before directly hitting land target.
  • Safety: The firing was successfully undertaken with dedicated support from Indian Navy which ensured that large number of monitoring ship are available for ensuring range safety clearance.
  • Significance: The capability of BrahMos missile coupled with superlative performance of Su-30MKI aircraft gives IAF its desired strategic reach.
  • Complex Process: The integration of missile weapon on aircraft was a very complex process which involved electrical, mechanical and software modifications on aircraft. The IAF engineers undertook software development of aircraft and Hindustan Aeronautics Limited (HAL) carried out mechanical and electrical modifications on aircraft.
  • Others involved: The dedicated and synergetic efforts of IAF, Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL) and BrahMos Aerospace Pvt. Ltd. (BAPL) proved the nation’s capability of undertaking such complex integrations.

About BrahMos Air Launched Missile

  • It is a 2.5 ton supersonic air to surface cruise missile. It range is close to 300 km, and is designed and developed by BrahMos Aerospace Pvt. Ltd. (BAPL).
  • The BrahMos missile provides IAF a much desired capability of striking on any target at sea or on land from large stand-off ranges with pinpoint accuracy by day or night and that too in all weather conditions.
