The Nelson was laid down in December 1922 at the Newcastle yard of Vickers-Armstrong. She was launched on September 3rd 1925 and completed in June 1927. In order to save weight extensive use was made of new materials in her construction, such as light weight steel, aluminium, fir for her deck in place of the traditional teak, and plywood for many internal non structural bulkheads and fittings, all of which was fireproofed.
