With reference to India's defence, consider the following pairs: Aircraft type : Description I. Dornier-228 : Maritime patrol aircraft II. IL-76 : Supersonic combat aircraft III. C-17 Globemaster III : Military transport aircraft How many of the pairs given above are correctly matched?

Pair I is correct: Dornier-228 is used by the Indian Navy and Coast Guard as a maritime patrol/surveillance aircraft. Pair II is incorrect: IL-76 is a heavy-lift strategic airlift/military transport aircraft, not a supersonic combat aircraft. Pair III is correct: C-17 Globemaster III is a strategic military transport aircraft operated by the Indian Air Force. Hence, only two pairs (I and III) are correctly matched.
