In 1934, the Regia Marina made an effort to replace the MAS units under the initiative of Admiral Domenico Cavagnari, who was serving as Sottosegretario and Capo di Stato Maggiore (Chief of Staff) of the Regia Marina from 1933 to 1940. The chosen replacement for the MAS was a motor torpedo boat called the Stefano Turr, which had a metallic hull and weighed 61.6 tons. However, as the MAS boats were becoming smaller and faster, the MAS 500 was ultimately selected due to its speed and suitable armament for engaging various enemy naval targets. On the other hand, the Stefano Turr had to wait for new engines, which were not developed until 20 years later. Consequently, the Stefano Turr motor torpedo boat was decommissioned and scrapped soon after World War II.

Introduced in [[Update "Starfighters"]], the Stefano Turr is fairly fast for its size. It is equipped with three 12.7mm machine guns and one 6.5 mm gun, along with additional armament comprising four torpedoes and 16 depth charges, allowing it to effectively destroy enemy targets. Utilizing its speed and manoeuvrability, the Stefano Turr can outmanoeuvre enemy vessels, flank them, and execute ambushes on larger ships using torpedoes and depth charges. Its survivability is also decent.

The Stefano Turr is surprisingly quite a survivable ship for its almost total lack of armour. It has a quite low crew of 16 people for its size. But this is its secret weapon in soaking up damage - similarly to tanks like the [[LVT(A)(1)]], its crew is quite spread out across the ship, meaning it will take more time to incapacitate them all, giving the player a chance of surviving. Beware that the armament operators are completely exposed meaning that you can easily lose one or more of your machine guns.

The mobility of the ship is really good for how big it is - you can keep up with many torpedo boats and leave slower ships like the [[VAS 201]] in the dust. One thing to note is its turning circle is quite large and it turns quite slowly. Overall it has really good speed in a straight time, but if you decide to turn, you'll lose a lot of speed.

=== Torpedo armament ===
+
The Stefano Turr is equipped with two types of machine guns for its primary armament - three 13.2 mm Breda machine guns arranged in a very asymmetrical layout in front of the bridge and a 6.5 mm Fiat machine gun on the stern. Overall, the three Breda machine guns are enough to make a dent in many enemy ships and are considered more effective than the 20 mm autocannons of other same BR italian boats. Due to their positioning you don't need to expose anything but your front to an enemy (in contrast to other low tier italian boats). The 6.5 mm is very weak and if you are flanked from the rear, it's better to turn around, rather than engaging them with the Fiat machine gun. The biggest drawback of the 13 mm machine guns is their rate of fire - lower than machine guns from other nations, especially German and American ones.

=== Special armament ===
+
The Stefano Turr can equip 4 x 450 mm S.I.170 torpedoes. Taking them is not advised most of the time as, if shot, they can detonate and critically damage the vessel, if not sinking it outright. The torpedoes themselves are average, with reasonable speed and enough explosive force to destroy most enemies. If you decide to take them, concentrate your torpedo fire on large and/or slow ships - prime examples are the [[SC-497]], [[PC-451]], [[Type K-3 No.1|Type K-3]], [[Type K-7 No.4|Type K-7]], [[Type 5]] escort boat, and Russian armoured river boats. Smaller boats, if prepared, will easily dodge them.

+
The Stefano Turr can also equip 12 B TG depth charges. They are next to useless, as they are made for destroying submarines, which are not in the game. Most ships, especially small boats, will easily escape the blast. The depth charge racks are considered an ammo rack and will explode and destroy the ship, once destroyed. Overall, taking depth charges are not recommended under any circumstances.

The Stefano Turr is an interesting ship to say the least - with its large profile, good speed but bad manoeuvrability, asymmetrical, mixed armaments and lots of torpedoes lead to a somewhat interesting playstyle. The main tactic when using her is as follows: Pick a target and face forwards towards them - this can maximise your survivability and you can use all of your best armaments this way. When facing a large, armoured ship, feel free to use the torpedoes. Its biggest disadvantages are the low rate of fire of the main weapons, the large profile and the lack of AI weaponry. These cons are quite minor and can easily be mitigated. Overall the Stefano Turr is a different ship from her Italian peers and can be very fun.

The Regia Marina attempted to replace the MAS units in 1934, on the initiative of Admiral Domenico Cavagnari (Sottosegretario and Capo di Stato Maggiore between 1933 and 1940), he picked the new ship that would replace the MAS, a motor torpedo boat with metallic hull and Stefano Turr hull of 61.6 tons but the project was too ambitious for the time being.

Indeed, the ship was larger than the MAS and it caused propulsion problems. The planned four 750 HP FIAT V 1616 fast diesel engine were insufficient to power the vessel in 1936 and it compromised the success of the project. A subsequent FIAT project, proposed in 1938, in view of the realization of a new type of 1,500 HP fast diesel engine, was rejected by the Ministry. A modified Turr based on 4 Isotta Fraschini Asso 1000 engines adapted to run on low pressure naphta was studied in 1938. It aimed at displacing 50 tons and sailing at 40 knots, but the engines in question were developed only twenty years later.

Description

In 1934, the Regia Marina made an effort to replace the MAS units under the initiative of Admiral Domenico Cavagnari, who was serving as Sottosegretario and Capo di Stato Maggiore (Chief of Staff) of the Regia Marina from 1933 to 1940. The chosen replacement for the MAS was a motor torpedo boat called the Stefano Turr, which had a metallic hull and weighed 61.6 tons. However, as the MAS boats were becoming smaller and faster, the MAS 500 was ultimately selected due to its speed and suitable armament for engaging various enemy naval targets. On the other hand, the Stefano Turr had to wait for new engines, which were not developed until 20 years later. Consequently, the Stefano Turr motor torpedo boat was decommissioned and scrapped soon after World War II.

Introduced in Update "Starfighters", the Stefano Turr is fairly fast for its size. It is equipped with three 12.7mm machine guns and one 6.5 mm gun, along with additional armament comprising four torpedoes and 16 depth charges, allowing it to effectively destroy enemy targets. Utilizing its speed and manoeuvrability, the Stefano Turr can outmanoeuvre enemy vessels, flank them, and execute ambushes on larger ships using torpedoes and depth charges.

The Stefano Turr can equip 4 x 450 mm S.I.170 torpedoes. Taking them is not advised most of the time as, if shot, they can detonate and critically damage the vessel, if not sinking it outright. The torpedoes themselves are average, with reasonable speed and enough explosive force to destroy most enemies. If you decide to take them, concentrate your torpedo fire on large and/or slow ships - prime examples are the SC-497, PC-451, Type K-3, Type K-7, Type 5 escort boat, and Russian armoured river boats. Smaller boats, if prepared, will easily dodge them.

The Stefano Turr can also equip 12 B TG depth charges. They are next to useless, as they are made for destroying submarines, which are not in the game. Most ships, especially small boats, will easily escape the blast. The depth charge racks are considered an ammo rack and will explode and destroy the ship, once destroyed. Overall, taking depth charges are not recommended under any circumstances.

Usage in battles

The Stefano Turr is an interesting ship to say the least - with its large profile, good speed but bad manoeuvrability, asymmetrical, mixed armaments and lots of torpedoes lead to a somewhat interesting playstyle. The main tactic when using her is as follows: Pick a target and face forwards towards them - this can maximise your survivability and you can use all of your best armaments this way. When facing a large, armoured ship, feel free to use the torpedoes. Its biggest disadvantages are the low rate of fire of the main weapons, the large profile and the lack of AI weaponry. These cons are quite minor and can easily be mitigated. Overall the Stefano Turr is a different ship from her Italian peers and can be very fun.

Pros and cons

Pros:

  • Good straight line top speed
  • Good survivability for a torpedo boat - small crew is spread around the entirety of a not that small ship
  • All of the best armaments are frontal facing and all armaments can be used in abroadside (because of the asymmetric positioning of the frontal weapons)
  • Good torpedoes can deal with armoured or heavy enemies

Cons:

  • Slow turn time
  • No armour
  • Large profile
  • Low main weapon rate of fire
  • Somewhat small main armament clips

History

The Regia Marina attempted to replace the MAS units in 1934, on the initiative of Admiral Domenico Cavagnari (Sottosegretario and Capo di Stato Maggiore between 1933 and 1940), he picked the new ship that would replace the MAS, a motor torpedo boat with metallic hull and Stefano Turr hull of 61.6 tons but the project was too ambitious for the time being.

Stefano Turr during seal

Indeed, the ship was larger than the MAS and it caused propulsion problems. The planned four 750 HP FIAT V 1616 fast diesel engine were insufficient to power the vessel in 1936 and it compromised the success of the project. A subsequent FIAT project, proposed in 1938, in view of the realization of a new type of 1,500 HP fast diesel engine, was rejected by the Ministry. A modified Turr based on 4 Isotta Fraschini Asso 1000 engines adapted to run on low pressure naphta was studied in 1938. It aimed at displacing 50 tons and sailing at 40 knots, but the engines in question were developed only twenty years later.
