Project history


The ships, which occurrence directly was linked to the effect called in due time by British scout Swift. He did not receive further development in the homeland, but made the big impression upon Italians, in which judgement she ideally approached for actions on the narrow Mediterranean theatre. In 1913-1915 in Italy first scouts of Poerio class were built, with approximately 1000t displacement. Before their completion, in 1913 working out of project of larger ship of this type has begun. Creation of rather solid 5000t scout with light armour was originally provided, however for financial reasons from this "almost a cruiser" have refused in favour of project of much more modest ship designed by Ansaldo (though at that time destroyers of the similar dimensions served only in Chilean and British fleets). Increased, in comparison with Poerio, almost in one and a half time displacement has gone on placing of more powerful machinery, eight (on two more) 102/35mm guns and 2 twin 450mm TTs. In total in 1916-1917 three ships were built. Shortage of light cruisers has forced to install on two ships heavy 152mm guns, however experience has appeared unsuccessful: 6`` guns had low firing rate and besides called strong concussion of the hull. In 1919 they were removed.

These ships were commissioned as scouts, reclassified as light scouts in July, 1921 and as destroyers in September, 1938.
