For 2016, CMMC is again adding several new museum exhibits, expanding our STEM Education programs, and strengthening our business operations. We are most in need of expertise in website upgrades & social media expansion, writing for a new newsletter and print articles, and researching and restoring vintage electronics for planned future exhibits.
Among our many other volunteer opportunities are event coordination, museum tour guides (no experience needed - we'll train you!), teacher assistance in our Summer Science program, and coordination of the Summer Speaker Series. If you have a skill and a few hours a week, we have a need. Have fun and make new friends at CMMC! To read more about volunteering at CMMC, click here.
We are located at 847 Orleans Rd (Route 28) in Chatham MA 02633.Click here for our museum schedule & map

Chatham’s top-secret role in defeating Germany during World War II came alive in 2015 as we remembered the 70th anniversary of the war’s end.
Stalking the U-Boats: Chatham Radio 1942-1945 was the theme for special exhibits. The museum remembered The Navy’s "Station C” which located marauding German U-Boats and intercepted their Enigma-encrypted radio messages, which was a key to winning The Battle Of The Atlantic.
Continuing this year, an interactive display features both a real German Enigma-cypher machine and two electronic Enigma simulators, which allow visitors to encrypt and decipher their own messages. The Enigma featured prominently in last year’s Oscar-nominated The Imitation Game.
Other interactive exhibits, including learning Morse code and tracing a ship-to-shore telegram through all of its steps, fill the museum, which traces 100 years of wireless communications.
Chatham Navy Radio played a significant role in defeating the Germans during the World War II Battle of the Atlantic by intercepting Enigma-encrypted wireless messages between German headquarters and its ships at sea, passing the intercepts on to Washington, DC for decoding. In addition, as the control station for the east-coast direction-finding network, Station C directed the search for telltale radio signals that allowed enemy vessels to be located and tracked.
