Atalante was laid down at Cherbourg in June 1865 and launched on 12 April 1867.
Her sea trials began on 1 April 1869 and she joined the reserve at Brest on 11 July 1869.
Atalante was commissioned on 23 February 1870 and was initially assigned to the Evolutionary Squadron before transferring to the Northern Squadron in July 1870 at the outbreak of the Franco-Prussian War.
The squadron was ordered to lift its blockade of the Prussian North Sea ports on 16 September and return to Cherbourg.
Atalante went back into reserve in November 1870, but she was recommissioned the following year.

She was named as the flagship of the Pacific Squadron on 1 July 1872 under command of Rear Admiral Baron Roussin.
On 14 August Atalante sailed from Lorient for the Pacific.
On 8 August 1873, Atalante was put into the Fitzroy Dock at the Cockatoo Island Dockyard in Sydney, Australia.
At the time she was the largest vessel to be drydocked in the harbour and the first ironclad to be docked in the Southern hemisphere.

She returned on 27 February 1874 where she placed into reserve but was recommissioned on 28 December 1875 as the flagship of the China Squadron under Rear Admiral Veron.
She departed Lorient on 10 January 1876, but returned on 16 May 1878.
The ship spent the next four years in reserve before being recommissioned on 3 July 1882 for service with the Cochinchina Division (French: division navale de Cochinchine).

Atalante was transferred to the new Tonkin Coast Division (French: division navale des côtes du Tonkin) when it was formed in 1883.
During 18–21 August 1883 she participated in the Battle of Thuận An.
This was an attack by the French on the forts defending the mouth of the Perfume River, leading to the Vietnamese capital of Huế in an attempt to intimidate the Vietnamese government.
Atalante was assigned to bombard the North Fort by the French commander, Vice Admiral Amédée Courbet.
After two days of bombardment a landing party from the ship captured the fort.
Ensign (French: Enseigne de vaisseau) Louis-Marie-Julien Viaud, who was aboard the Atalante during the battle and participated in the landing, wrote several articles graphically describing his experiences that were published in the newspaper Le Figaro under the pen-name of Pierre Loti.

The ship was assigned to the Far East Squadron (French: escadre de l'Extrême-Orient) under Admiral Courbet when it was formed by the amalgamation of the Tonkin Coast and Far Eastern Divisions in June 1884 in preparation for the Sino-French War of 1884–85.
In early September 1884 Atalante was in Huế, but she carried Admiral Courbet to Keelung on 23 September.
The ship was paid off into reserve in Saigon in 1885 and condemned two years later.
She fell into such a state of disrepair that "she foundered one night and gradually sank into the mud."
