UPSC 2003: With reference to Indian defence, which one of the following statements is correct?
(a)With the induction of Prithvi II, the IAF is the only air force in the world with surface-to-surface ballistic missiles under its command
(b)Sukhoi-30 MKI jet fighters can launch air-to-air and air-to-surface precision missiles
(c)Trishul is a supersonic surface-to-air missile with a range of 30 km
(d)The indigenously built INS Prabal can launch surface-to-surface missiles
Attempt This Question
Not attemptedCorrect Answer: (Ambiguous (both b and d are correct))
Both (b) and (d) are factually correct: (b) Su-30 MKI is capable of firing both air-to-air (e.g., R-77) and air-to-surface precision weapons (e.g., Kh-29). (d) INS Prabal, a Veer-class missile corvette built at Mazagon Dock and commissioned in 2002, is armed with 3M24E/Kh-35 surface-to-surface missiles, hence can launch SSMs. Statements (a) and (c) are incorrect—the USAF and others operate surface-to-surface ballistic missiles, and Trishul’s range is ~9–11 km, not 30 km.
