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?
- AOnly one
- BOnly two
- CAll the three
- DNone
Show answer
Answer: (B) Only two
Let's check each aircraft-description pair:
(I) Dornier-228 — Maritime patrol aircraft: CORRECT. The HAL/RUAG Dornier-228 is a light transport aircraft extensively used by the Indian Navy and Coast Guard for maritime surveillance and patrol missions. It is equipped with radar and surveillance systems for monitoring India's coastline and exclusive economic zone. ✓
(II) IL-76 — Supersonic combat aircraft: INCORRECT. The Ilyushin IL-76 (known as 'Gajraj' in the Indian Air Force) is a heavy strategic transport aircraft, NOT a supersonic combat aircraft. It is used for transporting troops, heavy equipment, and cargo. It is a large four-engine aircraft with a rear loading ramp — nothing like a supersonic fighter jet. ✗
(III) C-17 Globemaster III — Military transport aircraft: CORRECT. The Boeing C-17 Globemaster III is a large military transport aircraft used by the Indian Air Force. It can carry heavy equipment, vehicles, and large numbers of troops over intercontinental distances. India operates about 11 C-17s, which have been used for humanitarian missions and strategic airlift. ✓
Two pairs (I and III) are correctly matched. Answer is (b).
India operates specific aircraft types for different military roles - maritime patrol, transport, and combat - and UPSC tests whether students can distinguish between these categories.
The question tests if students fall into the trap of confusing transport aircraft (IL-76) with combat aircraft, which is a common misconception about large military planes.
Dornier-228 Maritime Patrol Aircraft
Science And Technology Dornier-228 Maritime patrol aircraft
Dornier-228: India's Coastal Surveillance Workhorse
HAL/RUAG Dornier-228 is a light transport aircraft used for maritime patrol by Indian Navy and Coast Guard
Equipped with radar and surveillance systems for monitoring India's coastline and EEZ
Twin-engine aircraft manufactured under HAL-RUAG partnership
Role & Capabilities
The Dornier-228 serves as India's primary coastal surveillance aircraft. Originally designed in Germany, it is now manufactured by Hindustan Aeronautics Limited (HAL) under partnership with RUAG Aviation.
• Primary users: Indian Navy, Indian Coast Guard, and Border Security Force
• Key missions: Maritime patrol, coastal surveillance, search and rescue operations
• Coverage area: India's 7,500 km coastline and Exclusive Economic Zone monitoring
Technical Specifications
Specification | Details |
|---|---|
Aircraft Type | Twin-engine light transport |
Primary Role | Maritime patrol & surveillance |
Surveillance Equipment | Radar systems, electro-optical sensors |
Operational Range | Approximately 1,500 km |
Crew | 2 pilots + mission specialists |
Trap: Don't confuse Dornier-228 with Dornier-328 (different aircraft family)
Key distinction: It's a patrol aircraft, not a fighter or heavy transport
Manufacturing: Made by HAL under German partnership, not fully indigenous
IL-76 Gajraj Transport Aircraft
Science And Technology IL-76 Supersonic combat aircraft
IL-76 'Gajraj': India's Heavy Lift Transport Aircraft
Ilyushin IL-76 (nicknamed 'Gajraj') is a heavy strategic transport aircraft, NOT supersonic combat aircraft
Used for transporting troops, heavy equipment, and cargo over long distances
Four-engine aircraft with rear loading ramp for heavy cargo operations
Aircraft Overview
The IL-76 is a Soviet-era heavy transport aircraft that forms the backbone of India's strategic airlift capability. Known as 'Gajraj' (elephant) in Indian Air Force service, it is designed for moving large cargo loads and troops across intercontinental distances.
IL-76 vs Combat Aircraft
Feature | IL-76 Transport | Combat Aircraft |
|---|---|---|
Primary Role | Cargo & troop transport | Air-to-air/air-to-ground combat |
Speed Category | Subsonic (below sound speed) | Supersonic (above sound speed) |
Design Focus | Large cargo bay, rear ramp | Weapons systems, maneuverability |
Crew | Large crew for logistics | 1-2 pilots for combat |
Examples | IL-76, C-17, C-130 | Su-30MKI, Rafale, F-16 |
Operational Uses
Strategic airlift: Moving heavy military equipment between bases
Humanitarian missions: Disaster relief and evacuation operations
Aerial refueling: Some variants serve as tanker aircraft
Special operations: Supporting missions requiring heavy cargo capability
Major trap: IL-76 is transport aircraft, not combat/fighter aircraft
Speed confusion: IL-76 is subsonic, not supersonic like fighter jets
Role clarity: 'Gajraj' carries cargo, not weapons for air combat
C-17 Globemaster III Transport
Science And Technology C-17 Globemaster III Military transport aircraft
C-17 Globemaster III: India's Premier Strategic Airlifter
Boeing C-17 Globemaster III is a large military transport aircraft used by Indian Air Force
India operates approximately 11 C-17 aircraft for strategic airlift missions
Capable of intercontinental cargo transport and humanitarian operations
Strategic Importance
The C-17 Globemaster III represents India's most advanced strategic airlift capability. Manufactured by Boeing, these aircraft enable India to project military power and conduct humanitarian missions across vast distances, including reaching remote locations with short airstrips.
C-17 Capabilities
Capability | Specification |
|---|---|
Cargo Capacity | Up to 77 tonnes of equipment |
Troop Transport | Up to 134 fully equipped soldiers |
Range | Approximately 4,400 km with full payload |
Landing Strip | Can use short, unpaved airstrips |
Special Feature | Rear cargo door for vehicle loading |
Operational Missions
Humanitarian operations: Disaster relief in India and neighboring countries
Strategic deployment: Moving troops and equipment to border areas
International missions: Evacuation operations from conflict zones
Logistics support: Supplying remote military bases and high-altitude posts

Correct classification: C-17 is indeed a military transport aircraft
Don't confuse: C-17 with C-130 Hercules (smaller tactical transport)
Key number: India has approximately 11 C-17s, not unlimited fleet

Classification of Aircraft in Indian Armed Forces
Indian military operates four main aircraft categories: combat, transport, patrol, and support aircraft
Combat aircraft are supersonic fighters; transport aircraft are subsonic cargo carriers
Each category serves distinct operational roles in national defense
