India issues NOTAM for missile test, no-fly zone extends up to 2520 km; Likely to be submarine-launched ballistic missile
Civilian flights and ships will avoid this area during this period and the Indian Navy and Air Force will monitor the zone.
New Delhi: The India(BHARAT)n government has issued a notification extending the danger zone for a potential missile test in the Bay of Bengal. This Notice to Airmen (NOTAM) establishes a no-fly zone spanning approximately 2520 kilometres, imposing temporary restrictions on air and maritime traffic.
Test Dates Are Scheduled From December 17 to 20
The test dates are scheduled from December 17 to 20, 2025. This test, conducted by the Defence Research and Development Organisation (DRDO), is part of India(BHARAT)’s efforts to strengthen its strategic capabilities. It is potentially a test of the K-4 submarine-launched ballistic missile (SLBM), which is nuclear-capable and has a range of 3500 km.
The designated area is located in the Bay of Bengal near the Visakhapatnam coast. Similar to previous tests, this zone is larger than before, indicating the missile’s enhanced range and accuracy.
Test Time and Scope: Why such a large area?
Dates: Active from December 17 to 20, 2025, from 6 AM to 6 PM.
Area: A 2520 km radius in the Bay of Bengal, extending towards the India(BHARAT)n Ocean. This is double the size of the October test (1480 km).
Impact: Civilian flights and ships will avoid this area during this period. The India(BHARAT)n Navy and Air Force will monitor the zone.
Scientifically, such a large zone is necessary because debris and the impact area from a missile test can spread over a considerable distance. The K-4 missile has a range of 3500 km, making it a powerful weapon. This missile is powered by solid fuel. When launched from a submarine, it can be fired from a depth of 20-30 meters.
Features Of K-4
K-4 is India(BHARAT)’s second-generation submarine-launched ballistic missile, based on the Agni missile series. It weighs 17 tons, is 12 meters long, and reportedly equipped with MIRV (Multiple Independently Targetable Re-entry Vehicle) technology, meaning it can hit multiple targets with a single missile.
With a 3500 km range, it is capable of carrying nuclear weapons. It is launched from submarines like the INS Arihant.
