Armament

Primary armament

Turret20 mm/65 Breda anti-aircraft gun
Ammunition1500 rounds
Belt capacity12 rounds
Fire rate240 shots/min
Vertical guidance-10° / 90°
The firing angles of the autocannon, unable to fire directly in front

The primary armament, in fact the only armament, is an Italian 20 mm cannon. It has a firerate of 240 shots/min and a 12 shot magazine before reloading for a minimum of 1.8 seconds. The cannon is unable to shot in front of the ship, it is necessary to locate broadside or turn your ship 180 degrees.

Three different belts containing two different shells are available:

  • Perforante mod.35 (unlocked by default): API-T · HEFI-T
  • Granata mod.35: HEFI-T · HEFI-T · HEFI-T · API-T
  • Perforante mod.35: API-T · API-T · API-T · HEFI-T

These belts are mostly the same, the HEFI-T belt is slightly more suitable against wooden boats, like PT-6 and the MTB 1, as well as low flying aircraft, while the API-T belt is slightly more suitable against component damage and steel boats, like the LS 3 and the G-5.

Additional armament

Setup 12 x 450 mm steam turbined W.200/450X5,75 torpedo
Setup 26 x B TG depth charge
Setup 32 x 450 mm steam turbined W.200/450X5,75 torpedo
6 x B TG depth charge

Two 450 mm steam turbined W.200/450X5,75 torpedoes on the left and on the right of the ship are a useful tool against larger sub chasers and gunboats when being able to sneak up. They have a maximum speed 81 km/h, a range of 3 km, and an explosive filler of 200 kg, enough to destroy any ship at the battle rating.

The MAS is one of the reserve boats able to carry six B TG depth charges with an explosive filler of 50 kg. These however are extremely situational and most of the time defensive in nature, as you have to drive in front of the enemy ship, or wait for the enemy to pass you, to utilize these weapons. Furthermore, 50 kg of explosives is very weak for a depth charge, as most others have around 100-140 kg of TNT, limiting effective use even further.

But despite the drawbacks, making a kill with these is one of, if not the most, satisfying ways to destroy an enemy player and equally humiliating for those who are on the receiving end.

Usage in battles

The MAS 555 is a rather strange boat, despite being the reserve boat equipped with the largest calibre, its slow firerate and small magazine, as well as the inability to fire directly forwards drastically limits its potential. However, it can still be a significant threat to other ships.

The best strategy whilst using the cannon is not to drive forward into battle, but to turn your rear to the enemy, and sailing in reverse. This way you can negate the limiting firing arcs at the front and still only reveal a small part of the hull, which extends your life expectancy by a few crucial seconds. The best way is to stay behind cover and move only rearwards when engaging and then back into cover. A one on one fight against almost any other PT boat will not go in your favour, therefore the element of surprise is most important.

Pros and cons

Pros:

  • Excellent speed forwards and in reverse
  • High crew count increases survivability

Cons:

  • Cannot fire directly forward
  • Small 12 shot magazines, therefore low fire rate
  • Very unstable gun platform, can be very difficult to make full use of each clip
  • Although it has the highest calibre armament of all reserve boats, the 20 mm does not consistently inflict damage unlike its counterparts

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
