Q50. What is the country of origin of the Rafale fighter jet procured by India?
[Rajasthan Police SI, 2016, Paper II]
(A) Russia
(B) United States
(C) France
(D) Germany
Answer: (C) France
Explanation: Rafale is a multirole combat aircraft manufactured by Dassault Aviation of France. India selected the French fighter to strengthen its airborne strike, air-defence and reconnaissance capabilities. Modern combat aircraft combine avionics, mission computers, sensors and precision weapons into an integrated operational platform.
Q49. Which Indian missile system can strike targets more than 5,000 kilometres away?
[BSNL JE, 26 September 2016, Shift 2]
(A) Arjun
(B) Akash
(C) Agni-V
(D) Nag
Answer: (C) Agni-V
Explanation: Agni-V is a long-range strategic ballistic missile developed by DRDO. Arjun is a tank, Akash is a surface-to-air missile, and Nag is a guided anti-tank missile. Unlike a cruise missile, a ballistic missile relies chiefly on its momentum and gravity after its initial powered stages.
Q48. Within which range could the land-launched Nag anti-tank missile strike targets, according to the paper?
[Telangana PSC Prelims 2016]
(A) 1 km
(B) 2 km
(C) 3 km
(D) 4 km
Answer: (D) 4 km
Explanation: The land-based Nag anti-tank guided missile was described with a range up to about four kilometres. Nag uses guided targeting intended to defeat protected armoured vehicles. Anti-tank weapons are designed to overcome vehicle armour, so seeker accuracy and the attack angle are particularly important.
Q47. Which Indian Air Force aircraft is used for in-flight refuelling?
[RPSC RAS Prelims 2016]
(A) Ilyushin Il-76
(B) C-130J Super Hercules
(C) C-17 Globemaster III
(D) Ilyushin Il-78
Answer: (D) Ilyushin Il-78
Explanation: The Il-78 is a tanker aircraft adapted for transferring fuel to other aircraft during flight. Air-to-air refuelling extends mission endurance and can increase the reach of combat aircraft. Aerial tankers support missions that would otherwise be limited by the combat aircraft’s fuel carried at take-off.
Q46. Which of these is a nuclear-powered submarine operated by the Indian Navy?
[RPSC RAS Prelims 2016]
(A) INS Shalki
(B) INS Sindhuvir
(C) INS Shishumar
(D) INS Chakra
Answer: (D) INS Chakra
Explanation: INS Chakra referred to the nuclear-powered Akula-class attack submarine leased from Russia. It is different from diesel-electric submarines in the other listed classes and from India’s indigenous Arihant strategic submarine.
Q45. Which of the following vessels is a submarine of the Indian Navy?
[MPPSC Prelims 2016]
(A) INS Viraat
(B) INS Sindhurakshak
(C) INS Rajali
(D) INS Vikrant
Answer: (B) INS Sindhurakshak
Explanation: INS Sindhurakshak was a Kilo-class diesel-electric submarine serving with India’s Navy. Viraat and Vikrant are aircraft-carrier names, whereas INS Rajali is a naval air station.
Q44. What is the name of India’s first indigenous nuclear-powered submarine?
[MP Vyapam Sub Engineer Electrical, 6 April 2016]
(A) INS Vagsheer
(B) INS Arihant
(C) INS Chakra
(D) INS Kalvari
Answer: (B) INS Arihant
Explanation: INS Arihant was built through India’s Advanced Technology Vessel programme. It is a nuclear-powered ballistic-missile submarine, contributing to the sea-based element of India’s deterrence capabilities. A ballistic-missile submarine is designed to provide survivable sea-based deterrence through concealed underwater patrols.
Q43. Which aircraft is identified in the paper as the first indigenous fighter of the Indian Air Force?
[CGPSC Prelims 2016]
(A) Tejas
(B) Vinashak
(C) Ojas
(D) Agni
(E) None of these
Answer: (A) Tejas
Explanation: Tejas is India’s indigenous light combat aircraft produced by HAL. While the older HF-24 Marut was India’s first indigenous jet fighter, this exam question specifically selected Tejas in its options. A fighter-aircraft programme requires flight-control engineering, avionics integration and years of flight-testing before operational induction.
Q42. Akash, developed by DRDO, is which type of weapon?
[RRB NTPC Tier I, 29 March 2016, Shift 3]
(A) Surface-to-air missile
(B) Surface-to-surface missile
(C) Air-to-surface missile
(D) Not a missile
Answer: (A) Surface-to-air missile
Explanation: Akash is a radar-supported surface-to-air missile system designed for engaging hostile aircraft and other aerial threats. It is a defensive missile, unlike ground-strike ballistic weapons. Surface-to-air interception also depends on radar detection, tracking information and coordination between the missile and its ground control system.
Q41. Which was India’s first indigenous aircraft designed and built by HAL?
[RRB NTPC Tier I, 29 April 2016, Shift 2]
(A) HF-25 MKI
(B) HT-2
(C) HT-3 MKI
(D) HF-28
Answer: (B) HT-2
Explanation: HT-2 was an Indian basic trainer aircraft designed and built by Hindustan Aircraft/HAL, making it an early milestone in the country’s indigenous aviation industry. It was not a combat fighter.
