📘 Q.4 IAS Prelims 2024 — Science & Technology (Fifth-Generation Fighter Aircraft)
🧷 Authentic Classroom Explanation by IAS Monk
📌 The Question:
Consider the following aircraft:
- Rafael
- MiG-29
- Tejas Mk-1
How many of the above are considered fifth-generation fighter aircraft?
(a) Only one
(b) Only two
(c) All three
(d) None
✅ Answer: (d) None
🧑🏫 Classroom Explanation:
Fifth-generation fighter aircraft are defined by a combination of advanced features, not by speed or weaponry alone.
🔹 Core characteristics of 5th-gen fighters include:
- Stealth shaping and materials (low radar cross-section)
- Internal weapon bays
- Sensor fusion
- Advanced avionics and network-centric warfare
- Supercruise capability (sustained supersonic flight without afterburner)
Now evaluate each aircraft:
🔸 1. Rafale ❌
- Classified as 4.5-generation
- Highly advanced avionics and electronic warfare
- Lacks full stealth and internal weapons bays
🔸 2. MiG-29 ❌
- A 4th-generation Soviet-era fighter
- Designed primarily for air superiority
- No stealth, no sensor fusion
🔸 3. Tejas Mk-1 ❌
- Classified as 4 / 4+ generation
- Indigenous, modern, fly-by-wire aircraft
- Does not meet fifth-generation stealth requirements
✔️ Hence, none of the listed aircraft qualify as fifth-generation fighters.
🔍 Curiosity Raiser:
✈️ Why is stealth more important than speed in modern air combat?
👉 Because the fighter you can’t see often wins before the fight begins.
📚 Enrichment Notes (UPSC Edge):
- True 5th-generation fighters include:
- F-22 Raptor (USA)
- F-35 Lightning II (USA)
- J-20 Mighty Dragon (China)
- Su-57 (Russia)
- India’s AMCA (Advanced Medium Combat Aircraft) is a 5th-gen project under development
- “4.5 generation” is an informal but widely used classification
