If there's one Battleship (more than any other), that best illustrates the requirement of, mounting as many naval guns on your battleship (as possible), then there's no finer example, than the Royal Navy's - HMS Agincourt:
HMS Agincourt (of 1913), mounted no fewer than, fourteen twelve-inch naval guns (in seven twin-turrets). This was done, to both maximise her fire-power, and increase the chances of hitting, an enemy battleship. I like the fact, that her turret arrangement, adhered to the principles of Naval Conflict, that had been learned in the days of Nelson's - HMS Victory: the more guns you have, the more fighting power, your warship - brings to bear :) And yet, perhaps unlike the days of HMS Victory, did this maximisation of guns - come with a price tag! In the case of Agincourt, carrying so many turrets (seven), meant that their weight had to be paid for, at the expense of adequate - armoured protection ... For me, this was particularly apparent, upon the thinness of her belt armour (up to nine inches), the thinness of her deck armour (up to two and a half inches), and the thinness of her bulkheads (up to six inches). Of these, I would say that it's the bulkheads thickness, that would concern me the most - as having seven gun turrets, could easily mean, that a fire/explosion, in one of their magazine's/shell handling room's, could easily spread, to an adjacent gun turret/group of turrets! And given the fact, that HMS Agincourt was regarded (amongst the Royal Navy), as a floating magazine - leads little to the imagination ... Despite this, did HMS Agincourt, have several features to her profile, that I quite liked ... First: was the fact that Agincourt, mounted all of her primary naval guns, on the centreline, of her hull form. This meant that she could bring all, primary guns to bear, on both port and starboard - which maximised her broadside. The adoption/standardised use of centreline turrets, went hand-in-hand, with the Space Age Idea, of super-firing turrets (where one turret's roof, was directly beneath, another turret's barrels). In the case of Agincourt, did this lead to an interesting arrangement, of her aft turrets - a little group of three, that was somewhat unique, in their layout :) Second: having so many primary naval guns (fourteen twelve-inch), was it also a key requirement, for the shell spotters, to have an unimpeded line-of-sight, towards the enemy. Thus, is it good to see, that her forward lookout platform (that's mounted atop the forward-most tripod mast), is actually located, in-front of the forward-most smokestack :) Third: Where as HMS Dreadnought (the so-called grandfather of all later/better battleships), had for the most part, omitted any (dedicated) secondary armament - the same could not be said, for HMS Agincourt. In the case of Agincourt, do I like the fact, that she featured twenty six-inch guns - that were all grouped, within the central third, of her hull form. For me, the inclusion of six-inch (surface target) guns, reflected a decent realisation of the (potential) menace of Destroyers and Patrol Boats (who could both launch torpedoes!). Yet here, do I find, that there's a secondary armament feature, that I was not so keen on ... The fact that her six-inch guns, were case-mated (i.e. built into the hull form), and that they were situated (mostly) beneath main deck level, meant that they would have been unusable, in anything but - a calm sea! Despite this, the inclusion of a (powerful) secondary armament, meant that Agincourt, did at least cater for, two different ranges, of Naval Engagement - both long range (with her twelve-inch guns), and short/medium range (with her six-inch guns). Which really was, a step in the right direction :) Overall: HMS Agincourt, was a (somewhat) novel solution, to the conflicting Naval requirements - of both maximising fire-power, and maintaining survivability. Ironically, the spread of her seven turrets, both aided survivability (as the chances of an enemy shell, knocking them all out - was much reduced), but the chances of an enemy shell, knocking out the entire battleship, was much increased (as the turrets were housed within a hull form, that did not have enough - armoured protection).
If there's one Battleship (more than any other), that's responsible for defining an entire genre of Warships, than that credit of distinction, belongs only to the Royal Navy's - HMS Dreadnought (of 1906):
HMS Dreadnought, was a World Above, the Warships that had come before her (the pre-dreadnoughts), and her design was so radical (at the time), that she gave her name, to all the Dreadnoughts that came after her (which we know by today - as Battleships). I especially like the fact, that HMS Dreadnought, helped redefine the definition/meaning of the phase: Naval Engagement ... This was achieved, through a Space Age Idea - that unified her primary armament, to be of all the same calibre of guns: ten twelve-inch naval guns. This in-turn, supported the idea of Naval Engagements, from greater distances - as shell spotters, only had to look for one type of shell splash (to help correct their aiming). But, why the requirement for a greater range of engagement? Well ... It was believed, that such Dreadnoughts, would no longer be within the range of - enemy torpedoes! It was an idea that was regarded as radical, because Navy Engagements (up to circa 1906), had always been fought, at closer ranges (being somewhat reminiscent, of the days of Nelson's - HMS Victory). When it comes to HMS Dreadnought's profile, there's three features, that stand out for me ... First: her high (ram shaped) bow. This would have helped with her sea keeping (of 21 knots), and have been useful (owing to its shape), for the ramming of enemy warships, and submarines! Second: the poles that extend along the side of her hull form. At first, I thought that these were a part of her armour - but they are in-fact, booms for her anti-torpedo nets (which would have been deployed, when she was in port, and/or when she was stationary). Third: the layout of her primary armament gun turrets (i.e. her ten twelve-inch naval guns). Three gun turrets were located on her centre line, and could fire on either beam - at an enemy located to port or starboard (as the turrets rotated). The remaining two turrets, were located on her beams/wings (one port, one starboard) - but could only fire at an enemy, located on the relevant beam/wing (owing to limited rotation, and no line of sight/fire across her main deck). Thus, do I like the fact, that HMS Dreadnought, could bring to bear: eight twelve-inch naval guns - for a full naval broadside! Despite this, are there two design features (of HMS Dreadnought), that I did not like ... First: was her complete lack (of a true) secondary armament. Having been so revolutionary, it was almost an afterthought, to have added in twenty-seven twelve-pounder guns (5.44 kilograms). These, were all mounted above deck, both on the roofs of her primary gun turrets, and within her topside superstructure. And as such, I find it slightly ironic/reflective, that these were the positions, that were used in later Battleship classes, for anti-aircraft arrangements. Thus did Dreadnought, lack any effective close range, medium calibre guns - that could have been of use, against enemy Patrol Boats and Destroyers (who ironically, could launch torpedoes!). Second: Was the location of her forward most, gun spotting platform (atop the tripod mast). Which could easily be smoked out, when she was at speed! Although to be fair, this particular design flaw, also affected - later Battleships. Overall: Dreadnought was the first of her kind, who sparked a Naval Arms race (as other countries wanted Dreadnoughts). Even so, there's one particular area, that Dreadnought often receives flak for - and that is, that her thickest belt armour (of 11 inches), was actually located beneath the waterline (when she was at sea), where it would do - little good! In any case, Dreadnought was a step in the right direction, as many of her novel features, made it successfully into - later Battleship classes :)
The third book on battleships that I have read, is Battleships - The Ultimate Guide to the World's Greatest Battleships:
The first fact I noticed about this book, is that it takes a different format ... Battleships are not presented country-by-country, they are instead broken down based upon their chronological classification: The Pre-Dreadnought Era, Dreadnought, The First World War, The Treaty Battleships, The Second World War, and the End of the Line (aka the swansong). Amazingly, this approach seems to work quite well! Another difference is the fact that this book is much more reading based - and yet, the book still manages to be crammed full of many high-quality battleship photographs :) You may think that the Pre-Dreadnought Era could be quite boring - but not at all ... I'm amazed that the Royal Navy built a fourteen thousand tonne, Royal Sovereign class battleship (called HMS Hood) in circa 1889. That fact made me wonder how many battleship classes, and battleship names have been re-used throughout naval history (as those of you who enjoy reading about battleships - shall be aware that the Royal Navy, also had a 1913 Royal Sovereign battleship class, and a later/better edition HMS Hood). My favourite chapters are The Treaty Battleships, and The Second World War - for one simple reason: battleships were clearly becoming larger and more powerful (despite the so called Washington Treaty). The book features one of the best descriptions of The Washington Treaty (and related) that I have ever read: an attempt to limit the expense of battleship building programs, by con-straining the amount of battleships each nation could have, together with the size and power of future battleships ... For me, the aim of such treaties, is no more clearly illustrated, than by the book's coverage, of the Royal Navy's Nelson class. As this book's stunning photos of HMS Nelson, only serves to highlight the fact, that Nelson had all three triple sixteen inch gun turrets mounted forwards, of the main superstructure - in a bid to save weight. Even so, this book helped me realise, that there was an unexpected side effect of such treaties: that there was nothing to stop the World's navies, improving/modernising existing battleships! This was especially true of Japan, who with an eye to future war, pretty much modernised her entire fleet - especially with regard to speed and protection. In doing so, such nations hotted up the battleship building programs again, ensuring that as World War Two broke out, most battleships would be true behemoths (the like of which had not been seen before!). I feel that this book, covers all of this in great detail, which is why it can be hard to put down :) Added to this, is the fact that the book goes one stage further, as it includes specific battleship technology sections ... Of these, my favourites are: armour protection (as I enjoyed reading about the evolution of battleship armour, especially that it's all wood backed!), inside a gun turret/naval gun (as it helped to make me aware, of the tasks undertaken by gun crews) and anti-aircraft defences (as it helped me realise, that later battleships featured three levels of such defences - long range for bombers, medium range for torpedo bombers, and short range for fighters that got through, including kamikaze). Overall: I found this book to be an amazing merger of battleship fact, battleship story/spirit, battleship history/war, and battleship photographs. Of these, there's one particular photograph (that for me), captures the Heart and Soul, of a battleship and her crew (more than any other): the USS North Carolina, as she steams to war ...
