Ship design can remain remarkably stable over long
periods of time or rapidly evolve. Technology is the driving force behind the
evolution in warship design. The frigate in the age of sail was little changed
in almost two centuries. With a single gun deck, the frigate was designed to
assist the battle line composed of ships of the line. The frigate's roles were
many. They scouted for the fleet, provided for relay of signals in battle or as
a courier of new orders to far flung squadrons. They served as commerce raiders,
hunted commerce raiders and served as flagship on distant stations.
This status quo changed dramatically in middle third of the 19th century.
The steam engine was technological father of all of the subsequent innovations.
In addition to providing propulsion independent of the wind, a host of other
revolutionary improvements opened their doors because of the steam engine. With
independent power in ever increasing strength, hulls were no longer limited in
length or displacement, by the use of wood as the construction material. At
first hulls were still built of wood but were made longer through the use of
iron supports. During the Crimean War both the French and British came up with
the innovation of adding iron armor to a wooden hull, making the hull impervious
to the shot and shell of the time. However, this was only done on a small scale.
Only restricted use floating batteries, incapable of ocean movement, received
this treatment.
After the end of the Crimean War
The Warrior
also introduced a period of experimentation in design and type classifications.
Before Warrior the ship of line was
the primary type of warship, consisting of two to four decks of guns. Frigates
with only a single gun deck were rated as 5th rates, unable to stand up to the
1st through 4th rate ships of the line. The Warrior
had only one gun deck and so by definition was a frigate and yet it was clearly
superior and stronger to the multiple gun deck wooden hull ships of the line,
even those with an iron armor sheathing, such as the Gloire.
The names of the types changed, with ships of line becoming battleships and
frigates becoming cruisers. The new type names reflected the ship's primary
mission.
For the next two decades there was a great deal of
experimentation in design in both battleships and cruisers until around 1880
when standard designs for both types appeared. For cruisers the rate system
again appeared with the cruisers typed 1st through 3rd rate. This system
classified the cruiser based on armor and size. 3rd rate cruisers generally had
an iron hull but no armor. They assumed the traditional frigate roles of
scouting and sea control and subsequently evolved into the scout cruiser.
Cruisers of the 1st and 2nd rate normally had an armored deck, which was turtle
back in design, with the deck centerline above waterline but with the edge of
the armored deck joining the hull below the waterline. In theory this armored
deck protected the buoyancy of the cruiser, as well as protecting the machinery.
With HMS Orlando, launched in
1888, the Royal Navy introduced a new type of cruiser called the armored
cruiser. The
The French Navy, ever alert to employ technical
innovation to overcome the numerical superiority of the Royal Navy, again stole
a march on their competition across the
The Dupuy
de Lôme was launched in 1890 and was an instant sensation.
Modest by armored cruiser standards later at the end of the 1890s, Dupuy
de Lôme seemed to pack a lot into her 6,406-ton displacement.
She carried two 7.6-inch, six 6.4-inch QF, twelve 2.5-inch QF guns and four
torpedo tubes. Her armor consisted of a 4-inch steel belt, 4-inch armor on gun
positions, and a 2-inch armored deck. Her machinery developed 14,000 ihp, which
gave her a top speed of 20-knots. The French navy fell in love with the type and
started building many more armored cruisers, only the subsequent designs were
bigger, stronger and faster. The
French saw this as the perfect weapon system against
It was not only the French who fell in love with
the armored cruiser. Any salt worth his salt, fell in love with it as well.
Looking at the design of the Dupuy de Lôme the reborn USN
greatly improved upon the type with
With their next design, the French dramatically
increased the displacement. The one-off, six funnel Jeanne
d'Arc displaced 11,270-tons with a main armament of two 7.6-inch
guns and a secondary of fourteen 5.5-inch guns. Armor jumped to 6-inches for the
belt, conning tower and turrets, while the casment secondaries received 5-inches
of armor. Machinery was also increased, developing 28,500 ihp with a maximum
speed of 23-knots. Although other navies had doubts about the design, French
naval writers very, very enthusiastic. "The
French have a high opinion of her, and a writer in the Yacht has expressed
himself in the following terms: 'A comparison between the Jeanne d'Arc and
vessels of the Powerful and Diadem classes shows that the English are less
ingenious than ourselves in the matter of naval construction. To know how to
unite a powerful armament with sufficient protection and high speed upon a small
displacement, is a veritable tour de force, and from this point of view it
cannot be denied that the Jeanne d'Arc, notwithstanding her defects, is a chef
d'oeuvre of naval architecture."
Following Jeanne
d'Arc, the French ordered three more classes of large armored
cruisers in rapid sequence. Each of the first two classes were of three ships
each with the last class of two ships and were of a very similar four funnel
design with only incremental improvements. First came the Montcalm
class of Montcalm, Gueydon
and Dupetit-Thouars
of 9,517-tons. The ships carried two 7.6-inch main guns in turrets and eight
6.4-inch guns in casemates. The armor scheme was the same of Jeanne
d'Arc, except casmate armor was reduced to 4-inches. The
machinery was less, developing 19,600 ihp for a top speed of 21-knots. The
following Condé
class of Condé, Sully
and Gloire
jumped to 10,000-tons with two 7.6-inch and eight 6.4-inch, this time all in
turrets. The deck armor dropped to 1.7-inches. The machinery produced 20,500 ihp
with a top speed of 21-knots. The last class consisted of two ships, Marseillaise
and Amiral
Aube, displaced 10,014-tons and was almost a repeat of the Condé
class but the armored deck back to 2.5-inches.
In addition to these three classes of large armored
cruisers, they came up with a fourth, smaller class of armored cruiser. As with
With their next program the French Admirals decided
to go with a top of the line armored cruiser with greater fire power than any of
their predecessors and a top speed to match contemporary first line armored
cruisers in other navies. The result was the Gambetta
class. There were three units Léon
Gambetta laid down January 1901 with the Jules
Ferry following in October and the Victor
Hugo lagging far behind, having been laid down in August 1903.
They were big ships, displacing 12, 416-tons and a waterline length of 476-feet
(486.75-feet overall). Previous classes mounting the 7.6-inch main gun had
mounted them in single turrets, giving the larger French armored cruisers a
decided under gunned status given their size and foreign contemporaries. With
the success of the twin gun 6.4-inch turrets of the Desaix
class, the Gambetta adopted twin gun
7.6-inch turrets, doubling the main gun armament of the previous first class
French armored cruiser designs. They were given sixteen 6.4-inch guns as a
secondary all mounted in side positions. On each side there were three twin gun
turrets along with two additional guns mounted
in casemates. Belt armor stayed at 6.75-inches but tapered at the end to
3-inches. Turret armor stayed at 8-inches for the main guns but barbette armor
was increased to the same 8-inches providing more substantial protection over
that in previous cruisers. Secondary turrets and casemate gun positions were
given 5.5=inches of armor. Conning tower protection remained at 8-inches.
Compared to the previous
At the same time these three were ordered a fourth
ship was ordered of a very similar design. The Jules
Michelet was larger with a waterline length of 485-feet (493-feet
overall) and displaced 12,600-tons. Oddly, given the extra displacement,
armament and armor were decreased in this one off odd ball. Although the belt
stayed the same turret armor, barbette armor and caemate armor all were
decreased. Main turret armor went to 6-inch with barbette armor at 5-inches.
Secondary turret and casemate armor reverted to 4-inches. More glaringly the
secondary armament reverted to six single gun 6.4-inch turrets with four
casemate guns giving the Michelet
a broadside of only five 6-4-inch guns as opposed to the eight gun broadside of
the Gambetta
class. Perhaps the French designers expected greater speed, as the Michelet
developed 30,196ihp. However, the design proved slower on trials and at
22.86-knots was the same speed of Victor
Hugo but slower than the Gambetta
and Ferry.
Laid down in June 1901 the Michelet
took a long time completing, even by French standards. Seven years after her
start Michelet was commissioned in
1908.
With the exception of the Jeanne
d’Arc, which had six funnels, all French armored cruisers had
four funnels. The next design was another one off but with the Ernest
Renan, six funneled armored cruiser made a come back. In a quest
for even greater speed, size and displacement took another jump. With a
waterline length of 515-feet (527.5-feet overall) and displacement of
13,644-tons, machinery was increased in the bigger hull. Laid down in October
1903, Renan
completed in 1908 and developed 37,700ihp. At trials she ran at a maximum speed
of 24.24-knots, one knot faster than the Gambetta
in spite of having 9,000 more horse power. Armament was slightly better than
that of the Michelet with a broadside of four 7.4-inch guns from two twin
turrets and six 6-4-inch guns for four single gun turrets and two casemate guns.
The armor scheme remained on par with the Michelet. So far the Léon
Gambetta class remained the best French armored cruiser design to
date, as the subsequent Michelet and Renan
classes were inferior in armor and armament with no significant increase in
speed.
With the last of the breed, French designers would
make up for the failures of past designs. Fifteen years earlier, the French navy
had started the mania of building armored cruisers with the Dupuy
de Lôme of 1890. In November 1905 the Edgar
Quinet was laid down at the
Still you have to give the Quinet
class their credit. They had the same dimensions as the Rousseau but displaced
14,000-tons. The pair had 40 boilers to feed the three triple expansion engines
driving the three screws. Quinet
developed 39,808ihp at trials and hit a maximum speed of 23.92-knots. In
addition to the main guns the class had a light QF armament of sixteen 9 pdr,
eight 3 pdr and two 1 pdr QF guns, as well as two submerged 18-inch torpedo
tubes. The six funnels were grouped into two groups of three funnels widely
spaced apart, giving them a handsome profile. Armor protection was still on a
scale inferior to the Gambetta
design with 6.75-inch belt, 2.5-inch deck, 6-inch for turrets, and 5-inches for
barbettes. However, casemate armor went up to 6-inches and the conning tower up
to 10-inches.
Combrig Edgar
Quintet
The
purpose of this article is to show the modeler their first glimpse of the Combrig
Edgar Quintet.
A full kit review will appear for model of the sister ship Waldeck
Rousseau.
Thanks to Combrig, you now can get a 1:700 scale of the best of the French armored cruisers, the Edgar Quinet. An ancestor of the heavy cruiser, the Edgar Quinet ditched the mixed armament of France other countries' armored cruisers and went to an all big gun armament of fourteen 7.6-inch guns mounted in twin gun turrets, single gun turrets and casemate guns. With a speed of 24-knots, the Edgar Quinet was a good design. There was only one problem. Across the channel the Royal Navy started building the Invincible class battle cruisers that put an end to armored cruiser mania and introduced battle cruiser madness.
