Description and construction
The
The boats were originally to be armed with three Škoda 66 mm (2.6 in) L/30[a] guns, and three 450 mm (17.7 in) torpedo tubes,[2] but this was changed to two guns and four torpedo tubes before the first boat was completed, to standardise the armament with the F group to follow.[4] A 40 cm (16 in) searchlight was mounted above the bridge.[11] The torpedo tubes were mounted in pairs, one between the forecastle and bridge, and the other on a section of raised superstructure above the aft machinery room.[7] They could also carry 10–12 naval mines.[4]
The sixth of its class to be completed, 79 T was laid down on 1 December 1913, launched on 30 April 1914, completed on 30 September 1914,[4] and commissioned the following day, two months after World War I began.[12] Before her commissioning, one 8 mm (0.31 in) Schwarzlose M.7/12 machine gun was included in the armament of all boats of the class for anti-aircraft work. Four mounting points were installed so that the machine gun could be fitted in the most effective position depending on the expected direction of attack.[13] Until October 1915, the boat was painted black, but from that point it was painted a light blue-grey.[6]
Career
World War I
The original concept of operation for the 250t-class boats was that they would sail in a flotilla at the rear of a cruising battle formation, and were to intervene in fighting only if the battleships around which the formation was established were disabled, or to attack damaged enemy battleships.[14] When a torpedo attack was ordered, it was to be led by a scout cruiser, supported by two destroyers to repel any enemy torpedo boats. A group of four to six torpedo boats would deliver the attack under the direction of the flotilla commander.[15] As the 250t-class boats came into service, they joined the 1st Torpedo Flotilla, which was initially led by the Novara-class scout cruiser Saida and later by her sister Helgoland. The 1st Torpedo Flotilla initially included two divisions of destroyers (1st and 2nd) and a division of torpedo boats (3rd), which the 250t-class boats joined. Throughout the war, 79 T remained with the 3rd Torpedo Division of the 1st Torpedo Flotilla.[16]
Not long after being commissioned, on 17 October 1914 79 T joined the rest of the 1st Torpedo Flotilla in an attempt to engage part of the French fleet operating in the southern Adriatic. The French were sailing in the vicinity of the island of Vis, but departed south during the night of 17/18 October, and the Austro-Hungarian flotilla was unable to launch an attack.[17] Also in October, 79 T undertook a patrol between the islands of Busi and Pelagosa, and on 9 November the boat patrolled near the island of Lagosta.[18] On 15 and 16 March 1915, 79 T, along with the old torpedo gunboat Magnet and 250t-class boats 75 T and 76 T, escorted the newly commissioned dreadnought battleship Szent István from the main Austro-Hungarian naval base at Pola – in the upper Adriatic – to the island of Pago to conduct firing exercises.[19] Led by Helgoland, the whole 1st Torpedo Flotilla steamed to the Ionian Sea over the period 11–15 April 1915 in search of the French fleet base, but the operation was unsuccessful.[17]
On 27 July, a group led by Novara and the scout cruiser Admiral Spaun, and escorted by the Huszár-class destroyers Scharfschutze and Uskoke along with 79 T, 75 T and 76 T shelled the railway line between Ancona and Pesaro during a seaplane raid on Ancona.[27] After the Italian airship Città di Jesi was downed on 5 August, 79 T towed her to Pola.[18] On 17 August, the 1st Torpedo Flotilla shelled the island chain of Pelagosa in the middle of the Adriatic, and 79 T was part of a force tasked to protect the southern approaches to the islands from enemy submarines. The success of this bombardment, which destroyed the only source of drinking water, caused the Italians to abandon Pelagosa.[28] On 9 September 1915, 79 T, 75 T and 76 T comprised the 3rd Torpedo Boat Group of the 3rd Torpedo Division.[29] On 9 November, 79 T was sweeping for mines off Parenzo on the western coast of the Istrian peninsula when she was attacked unsuccessfully with a torpedo by an enemy submarine.[18]
In late November 1915, the Austro-Hungarian fleet deployed a force from Pola to Cattaro in the southern Adriatic; this force included six of the eight T-group torpedo boats. This force was tasked to maintain a permanent patrol of the Albanian coastline and interdict any troop transports crossing from Italy.[30] On 9 December, 79 T, three destroyers, two Kaiman-class torpedo boats and two other 250t-class boats formed a group led by Szigetvár which escorted seaplanes during a raid on Ancona.[31] On 4 January 1916, 79 T laid mines in the Bay of Triest. A raid on the Otranto Barrage – an Allied naval blockade of the Strait of Otranto – was conducted by Novara, escorted by 79 T, 81 T, and the Kaiman-class boat 71 T on 3 April.[18][b] On the night of 31 May/1 June 1916, the Tátra-class destroyers Orjen and Balaton, accompanied by 79 T, 77 T and 81 T, raided the Otranto Barrage. Orjen sank one drifter with a torpedo,[32] but once the alarm had been raised, the Austro-Hungarian force withdrew.[33] After laying mines off the town of Rovigno in western Istria on 29 June, 79 T was transferred to the Bocche on 10 August.[18]
During 1917, 79 T was often employed in the minesweeping role and also escorted 34 convoys.[18] In the same year, one of 79 T's 66 mm guns may have been placed on an anti-aircraft mount. According to Freivogel, sources vary on whether these mounts were added to all boats of the class, and on whether these mounts were added to the forward or aft gun.[34] On 20 March, 79 T, 74 T, 77 T and 81 T comprised the 1st Torpedo Boat Group of the 3rd Torpedo Division.[35] On 21 May of that year, the suffix of all Austro-Hungarian torpedo boats was removed, and thereafter they were referred to only by their numeral.[2] On 28 November, several 250t-class boats were involved in two shore bombardment missions. In the first mission, 79 and two other 250t-class boats supported the bombardment of Senigallia by three destroyers, before they were joined by five more 250t-class boats and another three destroyers for the bombardment of Porto Corsini, Marotta and Cesenatico.[36] The bombardment damaged the railway tracks between Senigallia and Rimini and destroyed one locomotive and several wagons, but when the flotilla moved to attack two small steamers, an Italian armoured train arrived and engaged them with its 15 cm (6 in) guns, and they broke off. On the return voyage to Pola, the ships were apparently pursued by Italian warships, but Admiral Spaun sailed to provide support, and the Italians withdrew.[37] On 1 February 1918, a mutiny broke out among the sailors of some vessels of the Austro-Hungarian Navy at the Đenovići anchorage within the Bocche, largely over poor food, lack of replacement uniforms and supplies, and insufficient leave, although the poor state of the Austro-Hungarian economy and its impact on their families was also a factor.[38] At the time, 79 was underway to Antivari, but as she passed the Luštica peninsula she received an order to return to Đenovići. Her captain realised the situation and instead he moored in the Castelnuovo anchorage and put his crew ashore.[39] Loyal ships were despatched to the Bocche from Pola, but by the time they arrived on 3 February, the mutiny had ended,[38] and 79 returned to Đenovići.[39] On 9 May, 79 and 76 along with several Huszár-class destroyers escorted the two Erzherzog Karl-class battleships, Erzherzog Ferdinand Max and Erzherzog Friedrich, to the Bocche.[40]
By 1918, the Allies had strengthened their ongoing blockade on the Strait of Otranto, as foreseen by the Austro-Hungarian Navy. As a result, it was becoming more difficult for the
Transferred to Triest on 16 June,
Post World War I
The Austro-Hungarian Empire sued for peace in November 1918, and 79 survived the war intact.[2] Immediately after the Austro-Hungarian capitulation, French troops occupied the Bocche, which was treated by the Allies as Austro-Hungarian territory.[50] During the French occupation, the captured Austro-Hungarian Navy ships moored at the Bocche were neglected, and 79's original torpedo tubes were destroyed or damaged by French troops.[51] In 1920, under the terms of the previous year's Treaty of Saint-Germain-en-Laye by which rump Austria officially ended World War I, she was allocated to the Kingdom of Serbs, Croats and Slovenes (KSCS, later Yugoslavia).[52] Along with 76, 77 and 78, and four 250t-class F-group boats, she served with the Royal Yugoslav Navy (Serbo-Croatian Latin: Kraljevska mornarica, KM; Краљевска морнарица). Taken over in March 1921 when French forces withdrew,[52][51] in KM service, 79 was renamed T4.[4] At the outset, she and the other seven 250t-class boats were the only modern sea-going vessels in the KM.[53]
New torpedo tubes of the same size were ordered from the Strojne Tovarne factory in Ljubljana.[9] In KM service it was intended to replace one or both guns on each boat of the 250t class with a longer Škoda 66 mm L/45 gun, and it is believed that this included the forward gun on T4.[9] She was also fitted with one or two Zbrojovka 15 mm (0.59 in) machine guns. In KM service, the crew increased to 52,[9] and she was commissioned in 1923.[54] In 1925, exercises were conducted off the Dalmatian coast, involving the majority of the KM.[55] During a 1927 refit T4 was re-armed with a pair of Škoda 75 mm (3.0 in) L/30 guns that had been manufactured as deck guns for submarines, and were procured from the Škoda works in Plzeň, Czechoslovakia.[56] In May and June 1929, six of the eight 250t-class torpedo boats – including T4 – accompanied the light cruiser Dalmacija, the submarine tender Hvar and the submarines Hrabri and Nebojša, on a cruise to Malta, the Greek island of Corfu in the Ionian Sea, and Bizerte in the French protectorate of Tunisia.[57] The ships and their crews made a very good impression on the British while visiting Malta.[58] In 1932, the British naval attaché reported that Yugoslav ships engaged in few exercises, manoeuvres or gunnery training due to reduced budgets.[59] In the same year, T4 ran aground on the island of Drvenik Mali off the central Dalmatian coast. The hull broke in half; the bow remained on the island, and the stern was towed to the Tivat Arsenal in the Bay of Kotor, 240 km (150 mi) to the south. As a result, it became a standing joke among KM sailors that this made T4 the "world's longest torpedo boat".[60] Eventually both sections were scrapped where they were.[39]

Notes
- ^ L/30 denotes the length of the gun's barrel. In this case, the L/30 gun is 30 calibre, meaning that the barrel was 30 times as long as the diameter of its bore.[10]
- ^ The naval historian Zvonimir Freivogel observes that the information about the raid comes from a 1996 book by the Austrian naval historian Franz Bilzer, but Erwin Sieche, another Austrian naval historian, states in his 2012 book that there is no mention of this operation in the war diaries of the ships involved.[18]
- ^ Sources differ on what the exact time was when the attack took place. Sieche states that the time was 03:15 when the Szent István was hit,[43] but Sokol reports the time as 03:30.[42]
