This ship and the slightly smaller cruiser Lütf-ü Hümayun were similar in armament and performance to the Miaoulis, an unprotected cruiser acquired in 1879 for the navy of the Ottoman Empire's main naval rival, Greece.[2] The Russian Black Sea Fleet, another threat to the Ottoman navy, included the slightly larger unprotected cruiser Pamiat Merkuria.
