Jules Michelet was an evoliution of the previous Leon Gambetta armoured cruiser design, fitted with better boilers for more power, extra speed, and more modern marks of guns and revised armament in general. Jules Michelet had a relatively long career. Completed at Lorient Arsenal on the west coast in 1908, she entered service with the Mediterranean fleet, seeing action in the first world was as part of the 1st light division (With Renan and Quinet) for various operations in the Adriatic, North Africa, and salonika campaign. Postwar she was in Indochina as flagship until 1929, then a barrack ship and target ship in Toulon in 1937.
Development
Jules Michelet was one of the last French armoured cruisers ever built (if we make an exception for Algerie in 1931). She succeeded to the Léon Gambetta class as a one-off all around improvement based on a higher displacement, and succeeded b the larger Ernest Renan launched in 1906 and Edgar Quinet class launched in 1907-1908. The latter reached 14,000 tonnes and were heavily armed, with a uniform battery of fourteen QF 7.6-inch guns whereas Michelet had only four. She was an interesting transition towards the pinnacle of a development, with ships able to defend far flung outposts in the Empire, hunt down enemy trade, and take their place in a battle line if needed.
Jules Michelet was the result of unsatisfaction in the Marine Nationale about the speed of its cruisers. She was designed, under the direction of Bertin as a modified version of the Leon Gambetta class but slightly longer, still with similar machinery layout, with 28 boilers which made for 1,500 ihp (1,100 kW) more power than the Gambettas, reaching 22.5 knots (41.7 km/h; 25.9 mph) instead of 22, and still four funnels. But apart that, she shared the same armament as the Gambettas.
Ernest Renan was initially planned as the fourth ship in the Gambetta class, but naval architect Emile Bertin decided to modify the design in an attempt to further increase her speed. For this, he stretched the hull to incorporate additional boilers (a staggering 42 total, exhausted into six funnels). This made for 37,000 ihp and 23 knots. The next Quinet would be essentially close sisters.
Design of the class
Hull and general design
Essentially the Michelet was a “larger” (not longer) version of the Gambettas, displacing 13,105 t (12,898 long tons) for an overal lenght of 146.53 m (480 ft 9 in) and a beam of 21.41 m (70 ft 3 in), Draught of 8.41 m (27 ft 7 in) versus 12,500t, 148 m long, 21.4 m (70 ft 3 in) wide and 8.18 m (26 ft 10 in) in draft. As seen here, she was just deeper. This improved buoyancy, and stability as well. This margin enabled so top weight additions, notably in armament, and larger boilers.
Powerplant
Unlike the Gambettas which mixed 20 or 28 boilers of various types with VTE steam engines, Jules Michelet was heavier, and combined like the previous ships a triple shaft arrangement with three vertical triple expansion steam engines fed in turn by 28 Guyot du Temple boilers, for a total of 30,000 ihp (22,371 kW) instead of 27,500 PS (20,226 kW). The next increase benefited top speed by just half a knot, at 22.5 knots (41.7 km/h; 25.9 mph) versus 22 knots.
For range she carried 2,070 tonnes of coal versus 2065 tonnes, for a range of 7,500 nmi (13,900 km; 8,600 mi) at 10 knots (19 km/h; 12 mph) versus 6,600 at the same speed, so a net increase, mostly due to the greater efficience of the boilers.

Protection
The armor scheme was about the same, here are the two stats layed here:
Gambettas: Belt: 70-150, turrets: 200, barbettes 100-180, secondary turrets 130-165, barbettes 65-130, casemates: 140, lower deck 45-65 and main deck 35, CT 200mm
Michelet: Belt: 70-150, turrets: 200, barbettes 100-180, secondary turrets 130-165, barbettes 65-130, casemates: 140, lower deck 45-65 and main deck 35, CT 200mm

Armament
There were changes here as well: Albeit the main armament was unchanged with four 194 mm (7.6 in) guns in twin turrets fore and aft, the secondary armament comprised twelve (instead of fifteen on the Gambettas) 164 mm (6.5 in) guns, eight in single turrets (six twin turrets on the Ganbettas) and remaining four in casemates (like the Gambettas). The swap from twin to single turrets seemslike a drawback, as well as the loss of foire guns. However this was made for two reasons:
The new secondary guns had the same caliber but were of a new model, quicker firing and with greater range and muzzle velocity, but taking more space and weight so for weight distribution reasons, only single turrets were possible.
The second reason was that even if placed in new twin turrets, they could have cause extra topweight.
Now between the single, lighter turrets and increase draft they ended as better, more stable gun platforms with lower metacentric height.
This was completed by a tertiary anti-torpedo-boat battery of twenty four 47 mm (1.9 in) guns, all mounted in casemates.
There were also two submerged 450 mm (17.7 in) torpedo tubes. They were almost an afterthought, so no attention will be paid there.
194 mm/50 (7.6 in) M1902
On the cruiser Waldeck Rousseau.
These were similar in caliber, but more powerful models than those carried in the earlier ships. The 50 caliber (instead of the 194/45 Modèle 1893–1896) had far better caracteristics. It was shared with the cruisers Renan, the two Quinet class and the Liberté class battleships.
Cerectersitics: 15 t (17 short tons), 10.1 meters (33 ft) long, barrel 9.7 meters (32 ft) 50 caliber

Rate of fire: 2 rpm
Best range: 26 km (16 mi) at 45°
164mm/50 M1902
Not the same as the previous Gambetta class cruisers. Again, better than the Modele 1893-96 45 caliber. It was used on the Démocratie, Edgar Quinet, Ernest Renan and Jules Michelet.
Weight: 33,470 lbs. (15,180 kg), 398.0 in (10.110 m) bore 381.9 in (9.700 m)

Career of Jules Michelet
After entering service, Jules Michelet was placed in the cruiser squadron of the Mediterranean Fleet in Toulon. On 27 June 1912 during firing practice at Toulon, she had two gun explosions, killing 4, wounding 21, blamed on defective powder.
When the First World War broke up, she remained in the Mediterranean’s 1st light cruiser division, with Ernest Renan and Edgar Quinet, tasked to hunt down Admiral Souchon’s Med squadron, with SMS Goeben and Breslau. The division patrolled off North Africa preceded by twelve destroyers, heading for Philippeville on 4 August, until learning the citt had been shelled on the 3th by Souchon. Many reports also came out which suggested they would try to break out of the Mediterranean and head for home, to the French high command sent the division further west of Algiers to block the their path, but this never happened. Instead, they headed for Constantinople and did not preyed on French troopships to France.
The cruiser’s staff during the operation in Corfu
The division was sent to face the Austro-Hungarian Navy in the Adriatic, joined by Edgar Quinet to start a blockade, based in Navarino and under fleet commander Admiral Augustin Boué de Lapeyrère. They made a sweep on 16 August into the Adriatic until spotting SMS Zenta. This became the Battle of Antivari, and Zenta was sunk. The sweep stopped with the fleet withdrawing due to Austro-Hungarian U-boats being suspected on the area.
Later in the war, Jules Michelet lost all her 47 mm guns for just four 47 mm anti-aircraft guns (AA mount version of the Hotchkiss). She took part in the evacuation of the Serbian army from Corfu to Bizerta in 1915. Later she tupported the Allied operations, Salonika campaign. After the Armistice of Mudros she was sent through the Dardanelles and in the Black Sea by November 1918, entering the gold horn.

Postwar she was sent to French Indochina in 1922–1923 with Victor Hugo, leaving France on 12 October 1922, arriving on 19 April 1923 and staying in East Asian waters until 10 May, back in Toulon on 11 July. She would return as flagship with the Far East squadron, leaving Toulon on 15 June 1925, arriving in July and staying until replaced by Waldeck-Rousseau until May 1929, back home on 10 July 1929, paid off, placed in reserve, disarmed in 1930. No longer listed as cruiser, striken 1931, reaffected as barracks ship at Toulon. She was reassigned as target ship for aircraft and submarines. She was sunk by the submarine Thétis in 1937.
