The MAS 561 despite being a reserve defends itself very well. Instead of the classic steel that we are used to on the MAS we find wood.
 +
 
 +
This ship has the entire hull made of wood, more precisely we are talking about 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 it is one of the most resistant. It can withstand blows up to 20 mm, after 20 mm it really starts to struggle in fact it will take a few moments to sink you. On the MAS there are 15 sailors, seem few but if we compare them to the 6 members of the [[G-5]] and 7 of the [[LS 3|LS]] these 15 are enough and advanced. The advantage of having a relatively small ship and many members is that it will not take long to repair and extinguish 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 only for the armed forces. These two engines are also capable of going to -33 Km/h.

The '''MAS 561''' is equipped with two types of additional armament. The first one is the [[W.200/450X5,75 (450 mm)|W.200 torpedo]], a torpedo that without the modification of the improved torpedoing can navigate up to 81 km/h for 3 Km, while when the modification is sought the torpedo will lose 7 km/h but in compensation it will gain 1000 meters of range. These two 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 depth charge [[B TG depth charge|B TG]], these charges can equip two and being positioned in the back of the ship will be easier to use. The [[B TG depth charge|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 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...) 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 on 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 caliber, 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 drive 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 favor, so the element of surprise is very important.

The project for the MAS type "500" was presented in November 1935, because Italy needed motorboats armed with modern torpedoes (for that time) with a guaranteed speed of 44 knots assured by 2 petrol engines Isotta Fraschini "Asso" of 1000 Horses each.
 +
 
 +
This new class of MAS was studied by Cantieri Baglietto of Varazze and was shown to the Minister of the Navy and then accepted by Prime Minister Benito Mussolini.
 +
 
 +
The MAS type "500" were small fast wooden boats, unlike the MAS of the First World War they were much faster, and they got different armaments with time and also different modifications.
 +
 
 +
The MAS type "500" were composed of almost 100 units, these wooden boats then obtained several modifications such as the use of metal instead of wood for the hull of the boat, increase in size and increase of the crew.
 +
 
 +
The MAS type "500" were produced in series:
 +
 
 +
1st Series 
 +
 
 +
The first units of the MAS "500" had a wooden hull (the MAS 525 had a metal hull) with a hull with two steps and a range of 400 miles at 42 knots and 1000 at 6 knots with auxiliary engines.
 +
 
 +
'''The 1st Series MAS are:'''
 +
 
 +
There were 26 units of 1°Serie from MAS 501 to MAS 525 
 +
 
 +
and in particular the MAS 424 that had 3 Isotta Fraschini engines with 3 propellers instead of 2 but without auxiliary engines.
 +
 
 +
'''The 2nd Series MAS are:'''
 +
 
 +
There were 24 units of the 2ndSeries from MAS 526 to MAS 550.
 +
 
 +
The MAS of 2° Series have the greater dimensions, were equipped with a hull in wood with hull to edge to two steps with an autonomy of 360 miles to the maximum speed and of 1100 to 6 knots, the MAS 550 in particular had the hull in metal.
 +
 
 +
'''The 3rd Series MAS are:'''
 +
 
 +
There were 13 units of 3° Series from MAS 551 to MAS 564 divided into 2 groups.
 +
 
 +
1°Gruppo production from MAS 551 to MAS 554 with metal hull, range of 350 miles at maximum speed and 850 with auxiliary engines.
 +
 
 +
2nd Production group from [[MAS 555]] to MAS 564 with wooden hull, range of 395 miles and 913 miles respectively.
 +
 
 +
The MAS of 3rd Series changed the [[Breda Model 31 (13.2 mm)|13.2mm Breda machine gun]] with the 20/65 Breda machine gun, this made the gun more effective at medium distances against enemies
 +
 
 +
'''The 4th Series MAS are:'''
 +
 
 +
There were 12 units of the 4thSeries from MAS 566 to MAS 576 these units were almost identical to those of the 3rdSeries with some minor changes such as the adoption of the helm of maneuver in the bridge, the replacement of the shaft with a support for the Breda 6.5mm machine gun and the increase in the supply of shots for the Breda machine gun 20/65

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 were founded new military corps to counter the allies who continued to advance in Italy and was founded in particular the MNR (National Republican Navy) that is the fascist navy of the RSI, are put into service former ships of the Royal Navy and one of these was the MAS 561, was scheduled to be transferred to the Adriatic, then not carried out.
 +
 
 +
Later it was put into service but before the service in the MNR it was modified with the addition of two [[Breda-SAFAT (12.7 mm)|12.7mm Breda-SAFAT]].
 +
 
 +
Later the MAS 561 was renamed for German purposes in SA 16.
 +

The MAS 561 despite being a reserve defends itself very well. Instead of the classic steel that we are used to on the MAS we find wood.

This ship has the entire hull made of wood, more precisely we are talking about 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 it is one of the most resistant. It can withstand blows up to 20 mm, after 20 mm it really starts to struggle in fact it will take a few moments to sink you. On the MAS there are 15 sailors, seem few but if we compare them to the 6 members of the G-5 and 7 of the LS these 15 are enough and advanced. The advantage of having a relatively small ship and many members is that it will not take long to repair and extinguish the ship.

Main articles: 20 mm/65 Breda (20 mm), Breda-SAFAT (12.7 mm)

The primary armament is composed of two 12.7 mm and a 20mm, thanks to its 2 machine guns 12.7mm MAS 561 can cause serious damage in a short time to enemy ships while the 20mm causes little damage and has a very low rate of fire 

Additional armament

Setup 22 x B TG depth charge
Setup 32 x 450 mm steam turbined W.200/450X5,75 torpedo
2 x B TG depth charge
Main articles: W.200/450X5,75 (450 mm), B TG depth charge

The MAS 561 is equipped with two types of additional armament. The first one is the W.200 torpedo, a torpedo that without the modification of the improved torpedoing can navigate up to 81 km/h for 3 Km, while when the modification is sought the torpedo will lose 7 km/h but in compensation it will gain 1000 meters of range. These two 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 depth charge B TG, these charges can equip two 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 machineguns 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 as the plane is usually not as manoeuvrable as the boat he can no longer aim its machine gun fire towards you.

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...) 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 on 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 caliber, 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 drive 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 favor, so the element of surprise is very important.

  • Good Top speed - 80km/h in RB, 112 km/h in AB
  • Good rotation time (20 seconds circa RB, 20 seconds circa AB)
  • Good torpedoes(Speed 74 km/h, Range 4 Km, Explosive mass 200 Kg)

  • 20mm has small magazines and slow rate of fire ( 3 seconds circa for reload after 12 ammunitions)
  • Terrible survivability (compared to other ships).
  • The 20mm cannon is positioned at the back.
  • Angle of fire of the 20mm cannon only 270°, the cannon can’t shoot in the front of the ship

History

The project for the MAS type "500" was presented in November 1935, because Italy needed motorboats armed with modern torpedoes (for that time) with a guaranteed speed of 44 knots assured by 2 petrol engines Isotta Fraschini "Asso" of 1000 Horses each.

This new class of MAS was studied by Cantieri Baglietto of Varazze and was shown to the Minister of the Navy and then accepted by Prime Minister Benito Mussolini.

The MAS type "500" were small fast wooden boats, unlike the MAS of the First World War they were much faster, and they got different armaments with time and also different modifications.

The MAS type "500" were composed of almost 100 units, these wooden boats then obtained several modifications such as the use of metal instead of wood for the hull of the boat, increase in size and increase of the crew.

The MAS type "500" were produced in series:

The first units of the MAS "500" had a wooden hull (the MAS 525 had a metal hull) with a hull with two steps and a range of 400 miles at 42 knots and 1000 at 6 knots with auxiliary engines.
