Intelligent Design:
Evolution of the Armored
Cruiser
By Steve Cabral
April 2013
After the Crimean War, steam power and
exploding artillery shells greatly changed
naval construction techniques. Fearing the
damage shells could wreak on wooden ships,
France and Britain experimented with sheathing
ships in iron plate. The American Civil War
though saw the Confederacy in possession
of one slightly burned and sunken frigate,
the former USS Merrimack. Undaunted by a
ship that had burned to the waterline and
sank at its pier, they built a new superstructure
on the wreckage and sheathed it in iron.
The Confederates decided that their new
ship could easily break the wooden ship blockade
off Norfolk. After she did so, the U.S. sent
the USS Monitor to Hampton Roads, and so
was fought to a draw the first fight between
two armored ships. Has any history of this
battle not made it sound like the Rebels
built the CSS Virginia one day on a lark,
while after the First Battle of Hampton Roads
the U.S. Navy built the USS Monitor overnight?
The CSS Virginia took a year to build while
the Federal ship took four months.
In 1866 the Battle of Lissa was fought between
Austria and Italy, the first clash of armored
fleets. The armored ship was definitely here
to stay. In 1873 the first armored cruiser
was built by Russia and named General-Admiral;
she was followed by HMS Shannon (called initially
an armored frigate) in 1875. The first modern
armored cruiser was commissioned by France, Dupuy
de Lome, in 1887. The Imperial Japanese
Navy's Chiyoda, a protected cruiser, actually
set the pattern for armored cruiser design
as she had the new Vertical Triple Expansion
engine (VTE) that would dominate navies until
the steam turbine was introduced for capital
ships with HMS Dreadnought; the United States
used them off and on until USS Oklahoma,
the last VTE capital ship that was built.
Armament Around the World
In theory the armored cruiser was to be
capable of standing in the line of battle,
scouting for the battle fleet and showing
the flag in distant waters like traditional
cruisers. The navies of the world approached
the armament of armored cruisers in a number
of different ways. In the Russo-Japanese
War the Japanese armored cruisers successfully
stood in the line of battle, vindicating
the design and causing a flurry of armored
cruiser launchings at the beginning of the
20th century.

Eleven of the 35 were war losses, nine of
them in combat. The 9.2 gun was renowned
for inaccuracy and so cited by Adm. Ernest
Troubridge at his courts-martial for allowing
Goeben to escape in 1914.

12 x 5.9 and 10 x 3.4

Adalbert, Friedrich Carl (1-2-1): 4 x 8.2, 10 x 5.9, 12 x 3.45
Roon,
Yorck (1-2-1): 4 x 8.2, 10 x

Scharnhorst,
Gneisenau (1-3-1): 8 x 8.2,
6 x 5.9 and 18 x 3.45
Blόcher (2-2-1): 12 x 8.2, 8
x 5.9 and 16 x 3.45
In theory Scharnhorst and Blόcher should
be about the pinnacle of armored cruiser
design (Italy would disagree), yet in Great
War at Sea theyre both not very much
out of the ordinary, and markedly inferior
to many older ships gunnery-wise. The reason
is Germanys intransigent insistence
that their smaller-caliber guns were superior
to other nations larger guns. The
8.2 had a shell of 238 lbs, much closer
to the 7.5 200 lbs than the 9.4 322
lbs or 9.2 380 lbs.
So instead of
splitting between Primary and Secondary they
should be lumped in with 5.9 and have
just a Secondary and Tertiary rating. Worse,
the German cruiser classes ranged 17,000
and 21,000 yards respectively against the
25,000 yards of the British 9.2 gun,
so in a gunnery duel they were outranged.
By changing to pure Secondary status, the
advantage had by Adm. Sturdees 12 armed
battlecruisers will be readily apparent,
and odds of a stray magazine explosion being
inflicted on larger ships are reduced with
shorter-ranged guns. Naval Artillery
