The ships of the Ardito class were 74.8m (245ft 5in)long at the waterline and 73m (239ft 6in)long overall, with a beam of 7.3m (23ft 11in) and a draft of 2.4m (7ft 10in). They displaced695 long tons (706t)standard and up to 790 long tons (800t) at full load. They had a crew of 4officers and 65enlisted men. The ships were powered by two Parsonssteam turbines, with steam provided by four Thornycroftwater-tube boilers. The engines were rated to produce 16,000 shaft horsepower (11,931kW) for a top speed of 30 knots (56km/h; 35mph), though in service they reached as high as 33.4 knots (61.9km/h; 38.4mph) from 15,733shp (11,732kW). At a more economical speed of 14 knots (26km/h; 16mph), the ships could cruise for 1,200 nautical miles (2,200km; 1,400mi).[1]
The ship carried an armament that consisted of a single 120mm (4.7in) gun and four 76mm (3in) guns, along with two 450mm (17.7in)torpedo tubes. The 120mm gun was mounted on the forecastle and two of the 76mm guns were mounted abreast the funnels, with the remaining pair at the stern. The torpedo tubes were in single mounts, both on the centerline.[1]
On 11 July 1915 Ardito, Animoso, Ardente, and Audace escorted Quarto to the Palagruža (known to the Italians as the Pelagosa) archipelago in the Adriatic Sea, where they landed the vanguard of an occupation force. The auxiliary cruiserCittà di Palermo, the protected cruiser Marsala, the destroyer Strale, and the torpedo boatsAirone, Arpia, Astore, Calliope, Cassiopea, and Clio also took part in the operation, which went smoothly: Two Austro-Hungarian signalmen, who first hid from and then surrendered to the Italians, made up the archipelago's entire garrison.
At 04:00 on 17July1915 Ardito, together with Giuseppe Garibaldi, Vettor Pisani, Ardente, Strale, Airone, Arpia, Astore, Calliope, Clio, the armored cruiser Varese, and the torpedo boats Alcione, Centauro, and Cigno, took part in a bombardment of the Ragusa–Cattaro railway.[4] The Italian force broke off the bombardment when Vettor Pisani sighted an Austro-Hungarian submarine at 04:25. The Italians had begun their return voyage to Brindisi when the Austro-Hungarian submarine U-4 attacked the formation at 04:40 and torpedoedGiuseppe Garibaldi,[4] which sank within minutes.
A few hours after an Austro-Hungarian Navy force subjected Palagruža to a heavy bombardment during the night of 16–17 August 1915, Ardito, Quarto, Animoso, Intrepido, and the destroyer Impavido, which were on a cruise in the Adriatic Sea north of the line Brindisi–Cattaro, interrupted their operations to respond. They reached Palagruža at around 10:00 on 17August1915.[4]
During the night of 11–12 December 1915Ardito and the destroyer Simone Schiaffino escorted the steamshipsEpiro and Molfetta from Brindisi to Durrës (known to the Italians as Durazzo) in Albania, where the two steamers delivered supplies for the Serbian Army. After monitoring the unloading of the supplies, the destroyers escorted the steamers back to Brindisi.[5]
1916
On 23February1916, Ardito, Indomito, Impetuoso, and the protected cruisers Libia and Puglia positioned themselves in the harbor at Durrës to protect the withdrawal of the "Savona" Brigade. Starting on 24February1916, the five ships, together with the destroyers Irrequieto and Bersagliere and the auxiliary cruisers Città di Siracusa and Città di Catania, began to bombard advancing Austro-Hungarian troops who were about to occupy Durrës. In the following days they also bombarded Austro-Hungarian artillery positions on the mountain Sasso Bianco in the Dolomites near Durrës.
While Ardito and Città di Siracusa were inspecting the Otranto Barrage in the Strait of Otranto on 31May1916, the Austro-Hungarian destroyers Balaton and Orjen attacked the barrage and sank Beneficent, a naval drifter (an armed fishing boat) that was one of the vessels responsible for laying and supervising the anti-submarine nets that formed the barrage. Centauro and the destroyer Aquilone got underway from Brindisi to reinforce Ardito and Città di Siracusa, and the four ships intervened and forced the Austro-Hungarian destroyers to retreat.
On 2August1916, Ardito and the French Navy destroyers Bisson, Commandant Bory, and Commandant Rivière supported an incursion carried out by the motor torpedo boatMAS 6, supported by the torpedo boats 33 PN and 37 PN, into the harbor at Durrës. MAS 6 penetrated the harbor and launched a torpedo. Her crew believed they torpedoed a steamer, but Austro-Hungarian sources reported no ships sunk or damaged.[4]
1917
On 11May1917 Ardito, under the command of Commander Gottardi, got underway from Venice together with Animoso, Ardente, Audace, and the destroyer Giuseppe Cesare Abba to intercept an Austro-Hungarian Navy force consisting of the destroyer Csikos and the torpedo boats 78 T, 93 T, and 96 T sighted at 15:30 about 10 kilometers (5.4nmi; 6.2mi) away. However, the Italians were unable to engage the Austro-Hungarian ships before they reached the vicinity of the major Austro-Hungarian Navy base at Pola, and after approaching Pola the Italian ships gave up the chase and returned to Venice.[4]
On 29September1917 Ardito, now under the command of Capitano di corvetta (Corvette Captain) Inigo Campioni, a future ammiraglio di squadra (squadron admiral) and commander of the Italian battlefleet during World War II, put to sea with Ardente and Audace and a second formation made up of Giuseppe Cesare Abba, the scout cruiserSparviero, and the destroyers Giovanni Acerbi, Vincenzo Giordano Orsini, and Francesco Stocco to support a bombing raid by 10 Italian airplanes against Pola. They encountered an Austro-Hungarian force composed of the destroyers Huszár, Streiter, Turul, and Velebit and four torpedo boats on a similar mission against an Italian airbase. The Italians opened fire just before midnight at a range of 3,000 metres (3,300 yards), but received the worst of the initial exchange as the Austro-Hungarians concentrated their fire on the leading ship, Sparviero. Sparviero was hit five times, but only three men were wounded, and one Italian destroyer was hit. As the Austro-Hungarians retreated towards the shelter of their minefields, the Italians crippled Velebit and set her on fire. Another Austro-Hungarian destroyer took her in tow and both sides returned to port after an inconclusive exchange of fire inside the minefields later that night during the predawn hours of 30September..[4][6]
On 28November1917, an Austro-Hungarian Navy force consisting of Huszár, Reka, Streiter, the destroyers Dikla, Dinara, and Triglav, and the torpedo boats TB 78, TB 79, TB 86, and TB 90 attacked the Italian coast. While Dikla, Huszár, Streiter and the torpedo boats unsuccessfully attacked first Porto Corsini and then Rimini, Dinara, Reka, and Triglav bombarded a railway near the mouth of the Metauro, damaging a train, the railway tracks, and telegraph lines. The Austro-Hungarian ships then reunited and headed back to the main Austro-Hungarian naval base at Pola. Ardito, Animoso, Ardente, Ardito, Audace, Francesco Stocco, Giovanni Acerbi, Giuseppe Cesare Abba, Sparviero, Vincenzo Giordano Orsini, and the destroyers Aquila and Giuseppe Sirtori departed Venice and, together with reconnaissanceseaplanes, pursued the Austro-Hungarian formation. The seaplanes attacked the Austro-Hungarians without success, and the Italian ships had to give up the chase when they did not sight the Austro-Hungarians until they neared Cape Promontore on the southern coast of Istria, as continuing beyond it would bring them too close to Pola.[4]
1918
On 10February1918 Ardito, Aquila, Ardente, FrancescoStocco, GiovanniAcerbi, and GiuseppeSirtori — and, according to some sources, the motor torpedo boatMAS18 — steamed to Porto Levante, now a part of Porto Viro, in case they were needed to support an incursion into the harbor at Bakar (known to the Italians as Buccari) by MAS motor torpedo boats. Sources disagree on whether they remained in port or put to sea to operate in distant support,[7] but in any event, their intervention was unnecessary. The motor torpedo boats carried out their raid, which became known in Italy as the Beffa di Buccari ("Bakar mockery").[4]
By late October1918, Austria-Hungary had effectively disintegrated, and the Armistice of Villa Giusti, signed on 3November1918, went into effect on 4November1918 and brought hostilities between Austria-Hungary and the Allies to an end. At 15:30 on 4November, Ardito, after steaming from Venice, docked at Rovinj (known to the Italians as Rovigno), taking possession of the city on behalf of the Kingdom of Italy.[8] World War I ended a week later with the armistice between the Allies and the German Empire on 11November1918.
Post-World War I
After the end of World War I, Ardito′s armament was revised, giving her five 102mm (4in)/35-caliber guns, a single 40mm (1.6in)/35-caliber gun, and a pair of 6.5mm (0.26in)machine guns. The work was completed by 1920.[citation needed]
Ardito was reclassified as a torpedo boat on 1October1929. On 2October1931, she was struck from the naval register. She subsequently was discarded and scrapped.[2]
