Back to Special Cruiser Projects List:
One of the e-mails I have received lately regarded a cruiser with fifteen eight
inch as the main armament. I had recently drawn the
Italian Verona class
of heavy cruiser with nine or twelve eight inch guns. The Verona class were big
ships for cruisers, the twelve gun version being almost 650 feet long. To put
that in perspective, that is longer than the Andrea Doria class battleships.
Heavy cruisers of this period really did get 'big'. The German Hipper class,
then the US Baltimore and Des Moines classes even exceeded the Hippers. The Des
Moines type were the ultimate of heavy cruiser with their automatic 8" guns
spewing out shells twice as fast as the earlier ships. That meant that in regard
to the earlier ships the Des Moines had an equivalent armament of 18x8". A
massive advantage. I have wargamed the Des Moines class many times, the result
being that they go through their complement of shells very quickly and if their
opponents are still firing, they then have problems. On the other hand get a Des
Moines close enough to a battleship/battlecruiser, then they just overwhelm them
with fast firepower.
So a ship with fifteen eight inch guns is not the be all and end all. It is a
huge vulnerable monster with little armour when compared to the battleships of
the time which would cost not much more to build.
But, this is a page that explores the impossible, to hell with the costs.
I intend to explore two drawings, one with fifteen gun armament (Italian based), and the other
with sixteen eight inch guns in four quadruple turrets (British based). In addition to these I
might add a twelve gun version with 10" guns (using the British version).

The Royal Navy kept a very close eye on what was happening in the naval world.
Only the Japanese who had pulled a Bamboo Curtain down on its naval affairs and
so managed to surprise the world with the Yamato and other ships. The Royal Navy
was aware of the big German cruisers almost as soon as they were laid down.
Looking at their own in production and planned future heavy cruisers, they had
to note the large discrepancy in staying power between their ships and the German
cruisers. What was required was a cruiser killer. A battlecruiser with lots of
cruiser sized weapons. The Royal Navy already had experience with quadruple
turrets in the King George V type so downsizing those to an eight inch level was
not difficult for them.
