Why in News?

The Indian Air Force (IAF) to strengthen its defence capabilities has deployed three S-400 Triumf air defence missile squadrons along the borders with China and Pakistan.

  • India in 2018-19 signed a contract with Russia for five S-400 missile squadrons. Three have arrived, and the remaining two are delayed due to Russia-Ukraine conflict.
  • In another development, the Indian Defence Acquisition Council recently cleared the procurement of the Indian Long Range Surface Air Missile(LRSAM) system under Project Kusha.

What is the S-400 Triumf Missiles System?

  • About:
    • The S-400 Triumf is a mobile, surface-to-air missile (SAM) system developed by Russia, capable of intercepting and destroying various aerial targets, such as aircraft, drones, cruise missiles, and ballistic missiles.
    • The S-400 has a range of up to 400 km, at an altitude of up to 30 km and can engage up to 36 targets simultaneously, with four different types of missiles.

  • Importance for India:
    • India decided to procure the S-400 missiles to enhance its air defence capabilities and deterrence posture against China and Pakistan, which have been modernizing and expanding their air forces and missile arsenals.
      • India faces a two-front threat from China and Pakistan, which have been involved in several border disputes and conflicts with India over the years.
    • India’s acquisition is crucial to counter the growing presence and influence of China in the Indian Ocean Region, where China has been building ports, bases, and infrastructure projects.
      • India also wants to maintain its strategic autonomy and diversify its defence partners, amid the uncertainty and volatility of the global order.

What is Project Kusha?

  • Project Kusha led by the Defence Research and Development Organisation (DRDO) is an ambitious defence initiative by India aimed at developing its long-range air defence system by 2028-29.
    • Long-range air defence systems will be capable of detecting and destroying enemy projectiles and armour, including cruise missiles, stealth fighter jets, and drones at long range.
    • It will consist of three types of interceptor missiles, with ranges of 150 km, 250 km, and 350 km, and advanced long-range surveillance and fire control radars.
  • Project Kusha is expected to rival the effectiveness of the renowned S-400 system of Russia and the Iron Dome system of Israel.

Iron Dome System of Israel

  • It is a ground-to-air defence system that comprises radar and interceptor missiles that are capable of tracking and neutralising any rockets or missiles fired towards targets in Israel.
  • It was developed by the state-run Rafael Advanced Defense Systems and Israel Aerospace Industries and was deployed in 2011.
  • It is particularly useful in defending against rockets, artillery and mortars, as well as aircraft, helicopters and unmanned aerial vehicles (UAVs).
  • The Dome has a range of close to 70 km and has three crucial components, Detection and Tracking radar, Battle Management and Weapons Control and the Missile Launcher.

Q2. With reference to Agni-IV Missile, which of the following statements is/are correct? (2014)

  1. It is a surface-to-surface missile.
  2. It is fuelled by liquid propellant only.
  3. It can deliver one-tonne nuclear warheads about 7500 km away.

Select the correct answer using the code given below:

(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

Ans: (a)
