In early August 2026, India issued a Notice to Airmen (NOTAM) that closed a 2,530‑kilometre corridor over the Indian Ocean. The advisory, covering the surface to unlimited altitude, was interpreted by analysts as a precursor to a long‑range missile test, possibly involving an advanced Agni variant or the K‑4 submarine‑launched ballistic missile.

A few days later, on 6 August, India conducted a test‑flight of the Agni‑4 medium‑range ballistic missile from the Integrated Test Range in Chandipur, Odisha. The two‑stage solid‑propellant missile, capable of carrying nuclear or conventional payloads up to 1,000 kg, demonstrated a range of about 4,000 km and an accuracy of under 100 m CEP. Senior defence officials observed the launch, underscoring India’s expanding long‑range strike capability and its nuclear deterrence posture.
