Informing potential adversaries about intercontinental ballistic missile (ICBM) test looks logical, to not trigger false alert.

I can't find any info - do countries do it? Do some protocols exist for this?

Examples of recent ICBM launches:

by USA

by Russia


There is an agreement between the US and Russia, that specifically coordinates notifications of test flights for ICBMs in order to prevent nuclear war. It is the Ballistic Missile Launch Notification Agreement, started 1988.

This is referenced again, several times, in the Strategic Arms Reduction Treaty (START), since expired, and the current New Strategic Arms Reduction Treaty (New START).
