FUCHS Silkolene also dedicated many years on technical cooperation with the US Air Force, and was also involved with the supersonic passenger aircraft, Concorde. The company amassed expertise with synthetic lubricant technology, and Silkolene became a recognised world leader in the field of synthetic lubricants, including esters.
Synthetic lubricant technology continued, and in the early 90s, developments continued to include Aerospace engineering, along with motorsports, including rallying and motorcycle racing.
