MCQ 6. Nyoma Air Base, recently in news, is located in which of the following sectors of Ladakh?
1. Siachen Sector
2. Kargil Sector
3. Chushul Sector
4. Nubra Valley
Explanation:
• Nyoma is located in Eastern Ladakh, close to the Chushul–Demchok sub-sector.
• It is around 50 km from the Line of Actual Control (LAC) near Chushul, a historically sensitive military zone (Battle of Rezang La, 1962).
• Siachen (1) is in the north, nowhere near Nyoma..
• Kargil (2) lies in western Ladakh, far away from Nyoma.
• Nubra Valley (4) lies near the Siachen base and Khardung La, also not related
→ Thus, only Option 3 fits correctly.

MCQ 7. Why is Nyoma strategically important for India?
1. It is India’s only naval aviation base at high altitude.
2. It is the closest operational airbase to the LAC in Eastern Ladakh.
3. It is used exclusively for UAV operations.
4. It is located on the India–Pakistan border.
Explanation:
• Nyoma is one of India’s closest airfields to the LAC with China, enabling rapid troop deployment, supply, and surveillance.
• Option 1 is wrong → There is no naval aviation base in Ladakh.
• Option 3 is wrong → Nyoma hosts UAVs but not exclusively; it also supports C-130J, Chinook, Apache..
• Option 4 is wrong → Nyoma is near the India–China border, not Pakistan.
→ Option 2 is factually correct and matches the strategic importance.

MCQ 8. Which aircraft made the inaugural landing at the newly operationalised Nyoma Air Base?
1. C-17 Globemaster III
2. Sukhoi Su-30 MKI
3. C-130J Super Hercules
4. Rafale fighter jet
Explanation:
• Air Chief Marshal A.P. Singh made the first official landing at Nyoma on a C-130J Super Hercules, a tactical military transport aircraft capable of high-altitude operations..
• C-17 (1) is capable of high-altitude landings but not used for this event.
• Su-30 (2) and Rafale (4) are fighters—not used for the inaugural demonstration.
→ Thus, C-130J is the only correct answer.

MCQ 9. Which of the following air bases in Ladakh is the world’s highest airstrip?
1. Thoise
2. Daulat Beg Oldie
3. Nyoma
4. Fukche
Explanation:
• Daulat Beg Oldie (DBO) is located at about 16,700 feet, making it the highest operational military airstrip in the world.
• Nyoma (~13,700 feet) is high, but not the highest.
• Thoise and Fukche are also high-altitude bases but significantly lower than DBO..
→ Therefore, DBO (Option 2) is the correct choice.
