Project history

Sister-ship of Japanese protected cruiser Takasago. Ship was laid down at the initiative of Armstrong for sale to foreign customer. She was launched 4.7.1898 and named Fourth of July (probably, in view of hopes to sell her to the USA). In January, 1899 she was offered to Royal Navy, but purchase was refused, in May of the same year ship passed builder`s trials (without artillery), and only in January, 1902 the agreement on her sale to Chile under name Chacabuco has been issued. After that the artillery was installed, and 29.4.1902 ship departured Britain.     Design of Chacabuco differed by strong artillery at enough light construction, high speed but bad seaworthiness.    At designed 15750hp machinery power and 22.5kts speed on builder`s trials ship has shown 16034hp and 22.92kts, and according to Chilean data, in December, 1909 on 3hr trials she made 24.75kts.
