Project history

This class was built for Argentinian Navy under the order given out late 1909. Because of lacks which have come to light at trials and financial disagreements Argentinian Government as a result has ruptured the contract and refused already completed ships. Then Greece become interested in them and 12.9.1912 gained these destroyers at the price of 148,000 £ for each.    For their time ships had very strong armament. Smoke ducts were deduced into individual funnels that predetermined unique five-funnels outline profile of ships.    In 1916 3 destroyers (except Panthir, having problems with machinery) were captured by French troops and till the end of First World War served under French flag. For this time ships passed repair of boilers (on Aetos one of them was replaced by boiler from incomplete destroyer Enseigne Gabolde) and ships became three-funneled.    In 1924-1925 Aetos, Ierax, Leon and Panthir passed major repair and reconstruction by S. White (UK). On trials ships shown from 31.1 (Aetos) to 31.16 (Leon)kts. Cost of modernization was 110,000 £ for each ship.

Naval service

In 1916 3 destroyers (except Panthir, having problems with machinery) were captured by French troops and till the end of First World War served under French flag. Leon 22.1.1921 has lost a stern as a result of explosion of own DCs, but has been repaired.

Leon was damaged 17.4.1941 at collision with s/s Ardenna: as result of explosion of own DCs stern with screws and rudder (second time for service!) was broken off, but she was towed to Crete, where 15.5.1941 she was sunk by German aircraft. Panthir was laid up into reserve 29.9.1943, Aetos and Ierax late 1943. All three survived ships were handed over on demolition in 1946.
