Question

International civil aviation laws provide all countries complete and exclusive sovereignty over the airspace above their territory. What do you understand by 'airspace'? What are the implications of these laws on the space above this airspace? Discuss the challenges which this poses and suggest ways to contain the threat.

Ghissu Editorial · Accepted Answer

Airspace is the sovereign air column above a state's land and territorial sea, but international law sets no upper limit, while outer space above remains free for all. This grey zone enables satellite surveillance, spy balloons and space weapons, needing space awareness, integrated air defence and global norms.

**Introduction**

The Chicago Convention (1944) gives every state "complete and exclusive sovereignty over the airspace above its territory". It fixes no ceiling, and that gap is a security risk.

**Airspace and the Space Above It**

SKETCH: spectrum | From Sovereignty to Freedom
left: Sovereign airspace
right: Free outer space
- Civil air routes
- Balloons, hypersonics
- Karman line ~100 km
- Satellites in orbit

1. **Meaning**: Airspace is the air column above a state's land and 12 nautical mile territorial sea, where foreign aircraft fly only on the state's terms.
2. **Free space above**: The Outer Space Treaty (1967) bars national appropriation, so foreign satellites may lawfully overfly and image India.
3. **No agreed boundary**: The Karman line of about 100 km is only a convention, so the band between aircraft and satellites stays legally contested.

**Challenges and Ways to Contain the Threat**

1. **Legal surveillance**: Adversaries can image Indian military sites from orbit without breaking any law.
2. **Grey-zone intrusions**: High-altitude balloons, like the Chinese balloon downed over the United States in 2023, and hypersonic vehicles exploit the undefined band.
3. **Space weapons**: China's 2007 and India's 2019 Mission Shakti anti-satellite tests show orbits can become battlefields.
4. **Response**: The Defence Space Agency (2019), space situational awareness, the IAF's integrated air defence network, anti-drone systems after the Jammu Air Force Station attack (2021), and Indian advocacy at the UN for preventing an arms race in outer space must work together.

**Conclusion**

Sovereignty stops at an undefined ceiling and threats now move through that gap. A vertical security doctrine joining air defence, space awareness and global norms can protect India without curbing peaceful use of space.
