Brassey's Naval Annual 1915
Coventry Ordnance Works was a British manufacturer of heavy guns particularly naval artillery jointly owned by Cammell Laird & Co of Sheffield and Birkenhead, Fairfield Shipbuilding and Engineering Company of Govan, Glasgow and John Brown & Company of Clydebank and Sheffield. Its core operations were from a 60-acre (24 ha) site in Stoney Stanton Road in the English city of Coventry, Warwickshire.
At the end of 1918 it became a principal constituent of a brand new enterprise English Electric Company Limited. After World War II the works made electricity-generating machinery and heavy machine tools.
