The Wartime Broadcasting Service was an emergency service of the BBC intended to broadcast for over about three months after a nuclear attack on the United Kingdom, or if conventional bombing, missiles and/or shelling destroyed peacetime BBC transmitters, but it never was needed to go on air. By the end of the 1950s all then existing BBC TV and radio transmitters had been fitted with both emergency diesel generators and atomic fallout protection. It was scrapped in 1993, the transmitters were sold off and Kelvedon Hatch Secret Nuclear Bunker became a Cold War museum.
