Ship project history: First two of these armoured cruisers which have done many noise in XIX-XX centuries edge, have been bought up in Italy under construction and have made the basic battle force of Argentina Navy up to commission of dreadnoughts. Very successful project combining good protection and strong armament at limited displacement; some kind of small fast battleships. 2 more such ships (Mitra and Roca) were ordered to Ansaldo in 1901. In connection with peaking of the Russian-Japanese relations unsuccessful attempt to buy them for Russian Navy has been made, after which failure in the end of 1903 they were bought up by Japan (Nisshin and Kasuga).

    After modernization General Belgrano and Pueyrredon were re-classified as coast defence ships.

Ship protection: Main 150mm belt (full ship length, 2.8m high) and upper belt (52x2.0m) expanded to upper deck connecting with 150mm casemate protection, main and upper belts were closed by 150mm bulkheads abreast barbettes. Main belt thickness was 75mm on short parts at ship ends. 25mm deck was connected with lower edge of main belt by 38mm slopes. It has turtleback form and 38-25mm thickness outside barbettes. CT had 150mm sides. All 254, 203 and 152mm guns had 150mm protection.
