From when Iran launches towards US bases, this is the timeline when to expect it to impact or be intercepted:

🚀 Ballistic missiles: ~5–15 minutes depending on launch location and target. These are the main “minutes to impact” threat.

🛩️ Cruise missiles: ~1–2+ hours, depending heavily on route and launch point.

🛸 Long-range drones (Shahed-type): ~4–8+ hours in many scenarios.
