Submarine Radioman (RM) Challenge Coin

After years of requests, we’re excited to introduce the Radioman (RM) two-sided pewter coin, featuring bold dolphins, a radio mic, and lightning bolts—a true tribute to the communication experts of the submarine fleet.

Measuring approximately 4" x 2¼", this eye-catching coin captures the essence of the Radioman's role in style.

So, what exactly does a Radioman do on a submarine? A Radioman (RM) is the lifeline of communication, ensuring critical messages get sent and received both in and out of the depths. Whether it's sending secure transmissions, maintaining radio equipment, or working with other communication systems, RMs are the ones who keep submarines connected with the outside world—when every second counts, they’re the ones keeping the signal clear. And let’s not forget, they also boost morale with those all-important family-grams, keeping sailors connected to home during long deployments.
