📘 Q.14 IAS Prelims 2025 — Science & Technology (Defence Aircraft)

🧷 Authentic Classroom Explanation by IAS Monk


📌 The Question:

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?

(a) Only one
(b) Only two
(c) All the three
(d) None


Answer:

(b) Only two


🧑‍🏫 Authentic Classroom Explanation:

🔹 Pair I — Dornier-228 : Maritime patrol aircraft

The Dornier-228 is a twin-engine turboprop aircraft used extensively by the Indian Navy and Indian Coast Guard for:

  • Maritime surveillance
  • Coastal patrol
  • Search and rescue
  • Pollution monitoring

It is valued for its Short Take-Off and Landing (STOL) capability and multi-mission versatility.
Hence, Pair I is correctly matched.


🔹 Pair II — IL-76 : Supersonic combat aircraft

This pairing is incorrect.

The Ilyushin IL-76 is:

  • A strategic heavy-lift military transport aircraft
  • Used for troop movement, cargo transport, disaster relief, and logistics
  • Powered by turbofan engines, but not supersonic
  • Not a combat aircraft

Therefore, Pair II is wrongly matched.


🔹 Pair III — C-17 Globemaster III : Military transport aircraft

The C-17 Globemaster III is a strategic military airlifter used by the Indian Air Force for:

  • Long-range troop deployment
  • Heavy cargo transport
  • Rapid disaster response
  • Aeromedical evacuation

It combines intercontinental range with the ability to operate from short and semi-prepared runways.

Hence, Pair III is correctly matched.


📌 Therefore, two pairs (I and III) are correctly matched.


🔍 Curiosity Raiser:

Why do modern air forces invest more in transport aircraft than combat jets during peacetime?
Because logistics wins wars before weapons are fired.


🧠 Enrichment Notes (Prelims Edge):

  • Dornier-228 → Surveillance | Coastal security | STOL aircraft
  • IL-76 → Heavy lift | Logistics | Disaster relief | NOT supersonic
  • C-17 Globemaster III → Strategic + Tactical airlift
  • Supersonic ≠ Military
    Many military aircraft are subsonic but mission-critical
