Audace class guided missile destroyers - Not such a simple improvement

Note - I would go more into these ships history however I can’t really find any sources which do them any real justice for any real service history other than dates to construction and dates of decommissioning etc. Also the 1990’s - 2000’s modernization is included as a slightly different version of the 1980’s modernization as at some point the armament was modified however I lack a date and only know some limited changes that were made.

Reference - In terms of images for context of anyone viewing this Audace’s hull number is D 551, the sister ship Ardito’s hull number is D 550.

Background & History

The Audace class guided missile destroyers were a class of two guided missile destroyers built for the Italian navy starting in the late 1960’s, these ships were an improved design of previous Impavido which was built starting in the 1950’s. The Audace class itself was both a radical and minor upgrade in it’s own right as at a glance they may not look the same but upon closer inspection the similarities are visible, the ships design despite being a guided missile destroyer the main was in the form of it’s gun based weaponry as the missile armament was the exact same, however the gun armament consisted of far more modern weapons as well as including more modern radar systems along with other things.

In terms of these new weapon systems they were in the form of a modern Italian designed OTO Melara 127mm/54 guns which were split into a pair of super firing turrets giving the main battery much greater rate of fire and the secondary battery which consisted OTO Melara 76mm/62 M.M.I. guns from the 1960’s were replaced by the more well known OTO Melara 76mm/62 compact gun mounts. The ships did make some initial improvements in other areas as they came with 4 21 inch torpedo tubes (many sources say these are triple mounts however one source provides visual evidence indicating that their are only 4) along with the 2 triple 12.75 inch torpedo tube mounts however later on this would be reduced to the 12.75 inch tubes. The missile armament remained the same at first as just 40 RIM-24 surface to air missile which were fired from 1 Mark 13 missile launcher however in service they would receive a major modernization which reduced the main armament and added new missiles as the RIM-24 was replaced by the RIM-66, a 8 cell Albatros SAM launcher which used Aspide surface to air missiles, and 8 Teseo missile launchers which used Otomat anti ship missiles placed into 2 quad mounts, they also did replace the remaining OTO Melara 76mm compact gun mounts with compact SR or super rapid mounts which were faster firing versions, later on however two of the four mounts were removed likely between the late 1990’s and early 2000’s from my best estimations.

The ships themselves were both laid down in 1968, launched in 1971 and commissioned in 1972. During their careers they would undergo at least one major modernization in the 1980’s which did the changes mentioned previously, however none of the sources really go into discussing about their service history in any fair detail beyond the fact they are both used quite a bit in service and took part in the crisis in Lebanon in the 1980’s and the Gulf war in the 1990’s, both ships remained in service until September 28th, 2006 with a few of those final years due to a delay in Horizon program and both ships were only scrapped in 2018. Following the completion of the Audace class a new guided missile destroyer would not begin construction until 1989 when the succeeding Durand de la Penne class was laid down, yet despite how much time had passed the new class would be an enlarged version of the Audace class.
