India Extends Missile Test Danger Zone from 1,480 km to ~2,520 km in Bay of Bengal Between October 15–17

India has issued a Notice to Airmen (NOTAM) announcing a temporary no-fly zone over the Bay of Bengal, signaling preparations for a likely missile test between October 15 and 17, 2025. The restricted airspace covers a vast area, stretching approximately 2,520 kilometers, indicating a potential trial of a long-range or intermediate-range missile system.

According to the NOTAM, the restricted corridor originates from Abdul Kalam Island, India’s primary missile testing facility off the coast of Odisha, and extends southeast into the Bay of Bengal. The flight restriction will be in effect from 12:30 UTC on October 15 to 15:30 UTC on October 17, providing a three-day window for the anticipated launch.

While authorities have not officially confirmed which missile system will be tested, analysts point to India’s Long Range Anti-Ship Missile (LRAShM), a hypersonic weapon under development by the Defence Research and Development Organisation (DRDO). This missile is designed to enhance India’s long-range precision strike capabilities and strengthen maritime deterrence by targeting high-value naval assets at extended distances.

The Bay of Bengal has historically served as India’s missile testing corridor, offering wide-open space and minimal disruption to civilian air and sea traffic. Abdul Kalam Island, formerly Wheeler Island, continues to host the majority of India’s strategic missile trials, ranging from short-range to advanced long-range systems.

The extended duration and expanded coverage of this NOTAM suggest a significant developmental trial rather than a routine exercise. Observers note that such tests reflect India’s ongoing efforts to enhance deterrence and strategic readiness amid evolving security dynamics in the Indo-Pacific region.
