The U.S. Air Force has transmitted two rare, coded Emergency Action Messages (EAMs), signals typically reserved for critical military communications, often linked to nuclear command and control.
The first EAM was broadcast on Saturday and was significantly more complex than standard signals, which are usually around 30 characters long. This classified communication, usually made public a day later, on Sundays, spanned 246 characters. Its transmission coincided with consecutive bombardments between Israel and Iran, as the two Middle Eastern nations continued their exchange of attacks.
An EAM is sent digitally to primary nuclear-capable commands before being relayed to alert aircraft and nuclear submarines. This particular 20-minute transmission triggered alarm among social media users, who began posting about it.
A subsequent communication was sent on Sunday, this time 290 characters long, again via the U.S. Air Force’s Global High Frequency Communication System. This message was initially broadcast in low-quality signals before being re-transmitted.
Saturday also marked the 250th anniversary parade of the U.S. Army, which fell on the same day as President Donald Trump’s 79th birthday. These events are also being considered as potential subjects for the coded messages.
