Why the IAF NOTAM Northeast exercises now?
The IAF NOTAM Northeast exercises have drawn attention across India as the Indian Air Force (IAF) issued multiple Notices to Airmen (NOTAMs) for large-scale operational drills in the northeastern region. The move aims to strengthen dual-front preparedness, testing the IAF’s capability to manage simultaneous operations in the east and west.
According to verified defence reports from India Today and The Times of India, the NOTAMs—valid from September 25 to October 16—restrict civilian flight movement in sections of Assam, Arunachal Pradesh, Manipur, and Nagaland. These restrictions signal the start of one of the IAF’s largest coordinated air exercises in the region since Operation Sindoor.
Dual-front landscape demands readiness
The IAF’s decision to issue extensive NOTAMs in the northeast aligns with India’s evolving security environment. While military focus has often centred on the western border, eastern theatres bordering China, Myanmar and Bhutan are increasingly seen as strategic. The service’s largest drill in the region since Operation Sindoor is confirming this shift.
Strategic terrain: the Siliguri Corridor and beyond
The Siliguri Corridor, often called India’s “Chicken’s Neck,” is a slender land link of some 22 km that connects the northeastern states to the rest of India. The NOTAM-notified exercise zone includes airspace over this corridor and adjacent border zones, underlining the vulnerability and significance of the region in defence planning.
What the NOTAMs cover and what we know
Airspace closures and civilian impact
During the period from September 25 to October 16, the NOTAM restricted civilian flights in designated portions of northeast airspace—allowing the IAF to conduct complex operations without interference. Spots cited include major forward air bases and operational zones near Assam and Arunachal.
Nature of the exercises
The drills are set to include multi-axis operations: air-ground integration, deployment of frontline fighters, transport and rotary platforms, air-defence assets, and rapid mobilisation across terrain. Defence commentators say the IAF is validating its capability for simultaneous operations on more than one front.
Implications for the region and India’s defence posture
Strong signal of deterrence
By issuing the NOTAM across the northeast and staging large-scale exercises, the IAF is sending a message of operational readiness and deterrence. In regions that face multifaceted frontier challenges, such readiness is vital.
Increased awareness for airlines and stakeholders
Civil aviation operators, logistics providers and regional administrations must remain alert during such closures. The internal link to your earlier coverage of air-space safety may help: “Understanding NOTAMs and Restricted Airspace in India”.
Development of regional infrastructure
With increased military activity, infrastructure—airbases, logistics, surveillance systems—in the Northeast may receive added attention. This can lead to co-benefits for civilian connectivity, provided planning aligns with local needs.
Hurdles and things to monitor
- Terrain and weather constraints: The Northeast’s mountainous terrain and unpredictable weather amplify the complexity of such large drills.
- Civilian coordination: Ensuring minimal disruption to commercial air traffic, local communities and cross-border trade remains key.
- Inter-service coordination: Successful drills will depend on seamless integration across the IAF, army, and other support agencies.
- Transparency and communication: Timely notifications, updates and stakeholder engagement reduce misunderstanding and ensure safety.
What to watch next
- Formal announcements by the Ministry of Defence or IAF on after-action reports: assets used, lessons learned, future drills.
- Civil-aviation advisories for the region: flight rescheduling, alternate routes, passenger alerts.
- Local state-government responses: readiness of airports in Assam, Arunachal, Manipur, Nagaland.
- Broader pattern: whether east-sector drills become more frequent, indicating a strategic pivot.
Stay informed and engaged
A well-informed public supports meaningful national defence capabilities. Citizens, aviation stakeholders, regional press and analysts should:
- Subscribe to official NOTAM bulletins and civil aviation alerts.
- Ensure community awareness in states affected by air-space restrictions.
- Engage in constructive discourse on defence readiness — it is not just a military concern but part of national resilience.
With the issuance of these broad NOTAMs and the announcement of major northeast drills, the IAF is reinforcing its operational posture in a region of heightened strategic importance. Staying alert to developments, respecting air-space guidelines and understanding their implications will help civil and defence sectors work together.
