Cosmao was the third and final member of the Troude class of protected cruisers built for the French Navy in the late 1880s and early 1890s. The class was built as part of a construction program intended to provide scouts for the main battle fleet. They were based on the preceding Forbin class, the primary improvement being the addition of armor to the conning tower. Cosmao was built in the 1880s and was completed in 1890. She was armed with a main battery of four 138 mm (5.4 in) guns, protected with an armor deck that was 41 mm (1.6 in) thick, and had a top speed of 20.5 knots (38.0 km/h; 23.6 mph).
Cosmao served in the Mediterranean Squadron through most of the 1890s, where she was primarily occupied with training exercises with the rest of the unit. She was relieved of that assignment in 1898 and had been placed in reserve by 1901. She saw no further activity until the outbreak of World War I in August 1914, when she was assigned to a patrol group in French Morocco. Tasked with patrolling for German U-boats and protecting Allied merchant shipping, Cosmao saw no combat during the conflict. After the war, she was struck from the naval register in 1922 and thereafter sold to ship breakers.
