Following the introduction of ironclad warships in the early 1860s, naval designers grappled with the problem of mounting heavy guns in the most efficient way possible.
[4] The savings in weight could then be passed on to increase armor protection for the hull, improve coal storage capacity, or to install larger, more powerful engines.
[5] In addition, because barbettes were lighter, they could be placed higher in the ship without jeopardizing stability, which improved their ability to be worked in heavy seas that would have otherwise rendered turrets unusable.
The gun house was smaller and lighter than the old-style turrets, which still permitted placement higher in the ship and the corresponding benefits to stability and seakeeping.
[14][15] Ships equipped with barbette mountings did not see a great deal of combat, owing to the long period of relative peace between their appearance in the 1870s and their obsolescence in the 1890s.
Some barbette ships saw action during the British Bombardment of Alexandria in 1882,[16] and the French ironclad Triomphante participated in the Battle of Fuzhou during the Sino-French War in 1884.
[17] The two Chinese ironclads, Dingyuan and Zhenyuan, that took part in the Battle of the Yalu River during the First Sino-Japanese War in 1894, carried their main battery in barbettes, though they were equipped with extensive gun shields that resembled turrets.
