The War Emergency Radio Service (WERS) was a precursor to the civil defense and Radio Amateur Civil Emergency Service systems in the United States.
At the start of the Second World War the United States Congress had suspended all amateur radio activity throughout the country. WERS was established by the Federal Communications Commission in June 1942 at the insistence of the American Radio Relay League. WERS would remain in operation in through the end of the Second World War in 1945.
WERS was to provide communications in connection with air raid protection, and communications during times of natural disaster. WERS licenses were given to communities and not individuals. One of the requirements for individuals to participate in the WERS was to hold an Amateur radio license.
