British Naval Gun Mountings

Book excerpt: Heavy gun mountings dominated the design of larger warships, on account of their size, weight, protection and cost. In the 1890s, British gun mountings developed rapidly with new gun technologies (wire winding, cordite) and the rise of the two major ordnance companies, Armstrongs and Vickers, producing large numbers of weapons for the Royal Navy and for worldwide export. But by 1960, aircraft and guided missiles had made the big gun redundant, so the period from 1890s to 1950s covering the two world wars is the most historically significant. The focus of this book is on the larger mountings and those fitted in the larger ships – the massively engineered ‘non transferable’ mountings, whose complexities and associated magazines took up a huge volume of the ship, unlike the smaller calibre ‘transferable’ mountings mostly bolted to the deck. Such mountings could weigh over 1000 tons, take two years to build and make up a quarter of the cost of a battleship. Although they existed in many variants, there were only about forty basic mountings from 4.5in to 18in calibre fitted to the majority of the RN’s larger ships so these take up the bulk of the book. For each, well illustrated handbooks with colored plates were produced, but are largely inaccessible to the public, so about 50 of these highly detailed drawings are reproduced at large scale. The smaller mountings and the guns themselves each have a separate chapter. Although the impact of the book is largely visual, there is an expert account of the design, construction and installation of such mountings, and their manufacturers, supported by a range of internal and close-up photographs. The reference value of the work is enhanced by a comprehensive table of mountings and their characteristics, plus a list of all the mountings made by Vickers of Barrow between 1900 and 1950. Providing easy access to so much rarely seen material, this handsome volume will appeal to modelmakers, ship enthusiasts and technical historians.
