In 1964 the entire business transferred to the Alchem Works in Portsmouth. The business at Portsmouth consisted of chaff manufacture, an automatic machine shop producing mineral insulated cable connectors and a design and development department providing technical services.

By 1974 the Company was in good financial shape, and the Board applied for a full listing on the newly formed, United Stock Exchange (now the London Stock Exchange). Chemring was chosen as the name for the listed company, as this name was better known nationally and internationally.

The Falklands war in 1982 was a significant event, not only for the UK, but for Chemring. Sea skimming missiles were a major threat to the British fleet and aluminum glass chaff was seen as a key countermeasure. Chemring opened a new factory in weeks, and was acclaimed for its exceptional efforts during this period.
