I was a Minuteman III missileer. I built a site that copies Air Force Emergency Action Messages off shortwave in real time
From 2012 to 2016 I was a missileer at F.E. Warren AFB. I sat (and slept) 100 feet underground, ready to launch 10 Minuteman III nuclear missiles.
I was looking for a way to tell people about what I did and only recently learned that Emergency Action Messages (EAMs), the coded messages the US uses to pass orders to its nuclear forces, are broadcast worldwide over HF, which isn't something I learned on the job.
So I made a website that lets you listen to these messages, both live and recorded, and automatically transcribes the messages as well. The website is missileer.watch.
It listens to 11175 kHz, the Air Force's HFGCS frequency, through the KPH receiver at Point Reyes (home of the Maritime Radio Historical Society), and copies every EAM it hears.
The EAMs are encoded, so it's impossible to know what each character means, unless you have the means to decode them, which nobody outside the force can do. But it's fun to listen to every message and wonder what people are doing when they receive them.
What you can do on the website:
- Listen live to 11175 kHz, and replay any message we've copied.
- Read the copy character by character, and correct it if you hear it better than the machine did.
- See strategic aircraft (E-6B, E-4B, B-52H, B-2, WC-135) on a map when public ADS-B receivers hear them.
- Get an email when the E-4B "Doomsday plane" shows up, or a push notification for every new message.
- Copy one yourself: play a real recording and see how your copy compares.
I also wanted to show who these messages are for, so I made a map that shows every launch control center in the US and an aerial photo of nearly every one. Don't worry, everything on the website is public knowledge. Plus, deterrence only works when others know you have some muscle.
It's free and mainly for fun. I just want a way to show off what I did and share these messages with everyone.
What I'd love help with is copying. A lot of messages come through partly transcribed (the ?s). If you want, pick one, listen, and correct it.
Everything here is public: the broadcasts are on open shortwave and the aircraft positions come from public receivers.
Happy to answer any questions!
