Aircraft typeDescription
I.Dornier-228Maritime patrol aircraft
II.IL-76Supersonic combat aircraft
III.C-17 Globemaster IIIMilitary transport aircraft

How many of the pairs given above are correctly matched?

Answer & explanation

Answer: (b) Only two

Two of the three pairs are correct. The Indian Coast Guard describes the Dornier-228 as a multi-mission maritime patrol aircraft, and the C-17 Globemaster III is a military transport, but the IL-76 is a strategic airlift aircraft, not a supersonic combat aircraft.

  • ✓ I The Dornier-228 bought for the Indian Coast Guard is fitted with maritime patrol radar and an electro-optic infra-red device to strengthen aerial surveillance of maritime areas.
  • ✗ II The IL-76 (Gajraj) is described by the Ministry of Defence as an Indian Air Force strategic airlift aircraft. It is a transporter, not a supersonic combat aircraft.
  • ✓ III The C-17 Globemaster III was inducted into the Indian Air Force in 2013 to strengthen its strategic airlift.

Remember · Dornier-228: maritime patrol (Coast Guard). IL-76: strategic airlifter. C-17 Globemaster III: strategic military transport.
