The Committee which sat on the _Dreadnought_ design was by no means entirely unanimous as to what sacrifice should be made for speed. The _Dreadnought_ herself, despite a considerable increase of speed as compared with the battleships that preceded her, did not obtain that speed by the sacrifice of any battleship qualities, but almost entirely on account of the substitution of turbines for reciprocating engines. To that extent, therefore, though nearly as fast as the armoured cruisers of a few years before, she may be said to have developed entirely along normal lines, rather than on those laid down by Cuniberti. The table on the next page and diagrams indicate how the original Cuniberti idea compares with the first results obtained. It will be noticed that, except in the case of the _Invincible_ type, and there only at a sacrifice of armour and armament, was, however, anything like the Cuniberti speed attempted. It should be stated that in the Cuniberti ship the peculiar “girder construction” of his _Vittorio Emanuele_ was obviously contemplated. This construction, which admits of far lighter scantlings than usually employed, has not been attempted in any other Navies, and a corresponding extra dead-weight results. Coming to details, there is uncertainty as to the exact original design of the _Satsuma_; but a uniform armament of big guns was certainly the first to be projected. It is not clear whether it was abandoned from a preference for a numerically larger but mixed battery; or with a view to utilising such guns as were most likely to be available for early delivery. Japan was then at war, and there was the natural anticipation that the ships might be wanted before the war was over. It should, on the other hand, be borne in mind that the _Kashima_ and _Katori_, of 16,400 tons, carrying four 12-inch, four 10-inch, twelve 6-inch, and twelve 14-pounders, with 9-inch belts and 18.5 knot speeds were at that time held up in England on account of the war. Hence it has with some considerable show of reason been argued that the _Satsuma_ and _Aki_ are nothing but normal developments of the _Kashima_ design, bearing just the same relation to it as the British _Lord Nelsons_ bear to the _King Edwards_. It was also practically admitted by the Japanese at a later date that for diplomatic reasons, in accounts of the contemporary armoured cruisers of the _Tsukuba_ class, the armaments[31] were exaggerated.
