UPSC Prelims 2018 GS Paper I · Q43 of 100 General Science easy

What is "Terminal High Altitude Area Defense (THAAD)", sometimes seen in the news ?

  1. (a) An Israeli radar system
  2. (b) India's indigenous anti-missile programme
  3. (c) An American anti-missile system ✓ UPSC's answer
  4. (d) A defence collaboration between Japan and South Korea

Why the answer is (c)

• THAAD is a US Army anti-ballistic-missile system, built by Lockheed Martin, that intercepts short- and medium-range missiles in their terminal phase using hit-to-kill interceptors and an X-band radar — option (c).

• It was in the news when deployed in South Korea in 2017 against North Korean missiles, drawing Chinese objections.

• Israel's systems (a) are Iron Dome, David's Sling and Arrow; India's programme (b) is the DRDO Ballistic Missile Defence (PAD/AAD); Japan–South Korea (d) have no joint system.

• Hence option (c).

Why the other options are wrong

(a) An Israeli radar system
Israel's systems are Iron Dome, Arrow, David's Sling.
(b) India's indigenous anti-missile programme
India's programme is DRDO's BMD, not THAAD.
(d) A defence collaboration between Japan and South Korea
Japan and South Korea have no joint missile-defence system.
