📘 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
🪔 IAS Monk Whisper:
“Strength is not only in striking fast, but in moving silently, steadily, and surely.”
