Launch Complex 21 and 22 were built to launch Goose and Mace cruise missiles and shared a common blockhouse. Despite the fact that these sites supported the launching of the same missiles they were very different in nature.
The Goose and Mace missiles were launched from a horizontal position on a rail guidance system. Launch complex, 22 completed in February 1957, remained an an open site launching the missiles from rails which may have been on temporary or mobile launchers.
In all there were 23 launches from Launch Complex 22, the last being on July 17th 1963. The complex was eventually deactivated in the early 1970s.
