The '''{{Specs|name}}''' is a rank {{Specs|rank}} Italian motor torpedo boat {{Battle-rating}}. It was introduced in [[Update "Raining Fire"]].
+
The MAS 561 was a motor torpedo boat ('''M'''otoscafo '''A'''rmato '''S'''ilurante) of the MAS 500 class whose purpose was to attack enemy ships, and anti-submarine and escort operations. Built in 1941 with the others of the 3rd Series, the MAS 561 in particular was captured during the 1943 armistice of Italy by the Italians of the RSI (Italian Socialist Republic) i.e. the allies of Germany before the end of the war, and modified to add two [[Breda-SAFAT (12.7 mm)]] single mount machine guns, to increase its effectiveness against enemy Allied boats and to be used as anti-aircraft against enemy aircraft. Eventually, it was taken by the Germans and sank with its entire crew on 23 April 1945.
 +
 
 +
Introduced in [[Update "Raining Fire"]], the MAS 561 replaced the old reserve boat ([[MAS 555]]). It is the first Italian coastal ship you will play, and thanks to its speed you will be able to approach enemy ships quickly and launch torpedoes or depth charges causing serious damage to the enemy ship or its direct destruction. The armament consists of two 12.7 mm and one 20 mm guns, giving you good firepower against coastal boats. However, it is very fragile to enemy hits having little armour and a small crew.

This ship has the entire hull made of wood, more precisely 40 mm of wood for the hull and 15 mm for the superstructure. Against all expectations, this wood is much more effective than one might think, in fact as a reserve boat the MAS 561 is one of the most resistant to damage. It can withstand rounds up to 20 mm, although after 20 mm it will only take a few moments to sink. There are 15 sailors, which may seem few but are enough compared to the 6 members of the [[G-5]] and 7 of the [[LS 3]]. The advantage of having a relatively small ship and many members is that it will not take long to repair and extinguish fires on the ship.

The MAS 561 is propelled to a speed of 80 km/h thanks to 2 engines of 500 horsepower. The peculiarity of the MAS is that its 2 engines are civilian engines, not special engines for the armed forces. These two engines are also capable of going to -33 km/h.

''Describe the available additional armaments of the ship: depth charges, mines, torpedoes. Talk about their positions, available ammunition and launch features such as dead zones of torpedoes. If there is no additional armament, remove this section.''
+
The MAS 561 is equipped with two types of additional armament. The first one is the W.200 torpedo, a torpedo that can navigate up to 81 km/h for 3 km. With the torpedo mode modification, the torpedo will lose 7 km/h but in compensation it gains 1,000 m of range. These torpedoes are excellent for quick attacks on larger ships. With their good speed and 200 kg of explosive, it will be child's play to sink a ship.
 +
 
 +
The second additional armament of the MAS 561 is the B TG depth charge, two of these charges can be equipped and being positioned in the back of the ship will be easier to use. The B TGs with their 60 kg of explosive each are very effective to destroy ships that get a little too close, you can also flank the big ships and throw them at them.

To engage other small ships, it is better to maximize your firepower shooting from the side so you can use the machine guns and the 20 mm cannon at the same time.
 +
 
 +
To engage strafing aircraft, move in the same direction as the aircraft, lock the target, go to the gun sight view and lead your fire to the engine of the plane or cockpit if its a twin-engine plane. Once you destroyed it, or if you are not able to hit it, change direction with a sharp turn to avoid their return fire, as the plane is usually not as manoeuvrable as the boat.
 +
 
 +
To engage larger ships, you should use islands as cover to hide from their fire. It is useful to think a route to your target or destination (capture point, ambush position, etc) right from the start having all the present cover of the map and allies into account. To attack, you must get as close as possible to the target without getting destroyed. To do this, you must make sure the large ship is engaged in a firefight with another ship. Hold your fire to remain undetected and sneak to your target at high speed. Once you are close enough to launch a torpedo, launch them and get back behind cover as fast as possible using a smoke screen or terrain to conceal your escape.
 +
 
 +
The MAS 561 is a rather odd ship, despite being the reserve ship equipped with the largest calibre armament, its rate of fire and small magazine, as well as its inability to fire directly forward, drastically limit its potential. However, it can still be a significant threat to other ships. The best strategy when using the cannon is not to sail forward, but to turn your back on the enemy. This way you can use the full operational area of the weapon while exposing little of the hull, which increases the ship's survivability by a few crucial seconds. The best way is to stay behind cover and only move backwards when engaging and then return to cover. One-on-one combat against almost any other reserve will not work in your favour, so the element of surprise is very important.

After the armistice announced by Pietro Badoglio, 8 September 1943, the various military forces of the Kingdom of Italy were divided, and in 23 September 1943, Mussolini succeeded in founding the RSI (Italian Social Republic) and founded a new military corps to counter the Allies who continued to advance into Italy. In particular, the MNR (National Republican Navy), the fascist navy of the RSI, put into service former ships of the Regia Marina, one of which was the MAS 561. It was scheduled to be transferred to the Adriatic Sea, but was not carried out.
 +
 
 +
Later it was put into service, but before service in the MNR it was modified with the addition of two [[Breda-SAFAT (12.7 mm)|12.7 mm Breda-SAFAT]].
 +
 
 +
Later the MAS 561 was renamed SA 16 for German purposes.
 +
 
 +
On 23 April 1945, the MAS 561 sank with its entire crew.

Description

The MAS 561 was a motor torpedo boat (Motoscafo Armato Silurante) of the MAS 500 class whose purpose was to attack enemy ships, and anti-submarine and escort operations. Built in 1941 with the others of the 3rd Series, the MAS 561 in particular was captured during the 1943 armistice of Italy by the Italians of the RSI (Italian Socialist Republic) i.e. the allies of Germany before the end of the war, and modified to add two Breda-SAFAT (12.7 mm) single mount machine guns, to increase its effectiveness against enemy Allied boats and to be used as anti-aircraft against enemy aircraft. Eventually, it was taken by the Germans and sank with its entire crew on 23 April 1945.

Introduced in Update "Raining Fire", the MAS 561 replaced the old reserve boat (MAS 555). It is the first Italian coastal ship you will play, and thanks to its speed you will be able to approach enemy ships quickly and launch torpedoes or depth charges causing serious damage to the enemy ship or its direct destruction. The armament consists of two 12.7 mm and one 20 mm guns, giving you good firepower against coastal boats. However, it is very fragile to enemy hits having little armour and a small crew.

The MAS 561 is equipped with two types of additional armament. The first one is the W.200 torpedo, a torpedo that can navigate up to 81 km/h for 3 km. With the torpedo mode modification, the torpedo will lose 7 km/h but in compensation it gains 1,000 m of range. These torpedoes are excellent for quick attacks on larger ships. With their good speed and 200 kg of explosive, it will be child's play to sink a ship.

The second additional armament of the MAS 561 is the B TG depth charge, two of these charges can be equipped and being positioned in the back of the ship will be easier to use. The B TGs with their 60 kg of explosive each are very effective to destroy ships that get a little too close, you can also flank the big ships and throw them at them.

Usage in battles

To engage other small ships, it is better to maximize your firepower shooting from the side so you can use the machine guns and the 20 mm cannon at the same time.

To engage strafing aircraft, move in the same direction as the aircraft, lock the target, go to the gun sight view and lead your fire to the engine of the plane or cockpit if its a twin-engine plane. Once you destroyed it, or if you are not able to hit it, change direction with a sharp turn to avoid their return fire, as the plane is usually not as manoeuvrable as the boat.

To engage larger ships, you should use islands as cover to hide from their fire. It is useful to think a route to your target or destination (capture point, ambush position, etc) right from the start having all the present cover of the map and allies into account. To attack, you must get as close as possible to the target without getting destroyed. To do this, you must make sure the large ship is engaged in a firefight with another ship. Hold your fire to remain undetected and sneak to your target at high speed. Once you are close enough to launch a torpedo, launch them and get back behind cover as fast as possible using a smoke screen or terrain to conceal your escape.

The MAS 561 is a rather odd ship, despite being the reserve ship equipped with the largest calibre armament, its rate of fire and small magazine, as well as its inability to fire directly forward, drastically limit its potential. However, it can still be a significant threat to other ships. The best strategy when using the cannon is not to sail forward, but to turn your back on the enemy. This way you can use the full operational area of the weapon while exposing little of the hull, which increases the ship's survivability by a few crucial seconds. The best way is to stay behind cover and only move backwards when engaging and then return to cover. One-on-one combat against almost any other reserve will not work in your favour, so the element of surprise is very important.

Pros and cons

Pro:

  • Good top speed - 80 km/h in RB, 112 km/h in AB
  • Good turn time (~20 seconds AB/RB)
  • Good torpedoes (speed 74 km/h, range 4 km, explosive mass 200 kg)
  • Good acceleration
  • Good armament: two 12.7 mm machine guns and one 20 mm cannon
  • Effective 12.7 mm machine gun

Cons:

  • No armour
  • 20 mm has small magazines and slow rate of fire (~3 seconds for reload after 12 rounds)
  • Terrible survivability (compared to other ships)
  • The 20 mm cannon is positioned at the back
  • Angle of fire of the 20 mm cannon only 270°, the cannon can't shoot towards the front of the ship
  • No anti-aircraft protection
  • Aircraft can strafe the ship and knock it out with a few well placed shots.

History

Main article: History of the Velocissimo Classe 500

After the armistice announced by Pietro Badoglio, 8 September 1943, the various military forces of the Kingdom of Italy were divided, and in 23 September 1943, Mussolini succeeded in founding the RSI (Italian Social Republic) and founded a new military corps to counter the Allies who continued to advance into Italy. In particular, the MNR (National Republican Navy), the fascist navy of the RSI, put into service former ships of the Regia Marina, one of which was the MAS 561. It was scheduled to be transferred to the Adriatic Sea, but was not carried out.

Later it was put into service, but before service in the MNR it was modified with the addition of two 12.7 mm Breda-SAFAT.

Later the MAS 561 was renamed SA 16 for German purposes.

On 23 April 1945, the MAS 561 sank with its entire crew.
