A viral narrative claiming that Iranian missile silo hatches were opening “every 8 minutes” while a B-2 Spirit observed or “counted” them appears to be unverified and likely dramatized, with no credible reporting confirming such a sequence of events.

What is real
The U.S. has conducted major stealth bombing operations against Iranian underground facilities using B-2 bombers, including the large-scale strike known as Operation Midnight Hammer
These bombers are specifically designed to target deep underground sites, including missile bases and nuclear facilities using bunker-buster bombs
Iran does maintain an extensive network of underground missile silos and “missile cities”, built to survive airstrikes and conceal launch activity
