Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.

Mobility

Speedforward / back

AB82 / 31 km/h

RB61 / 23 km/h

The speed of the MS-473 is quite good, and thanks to its manoeuvrability that gives you the ability to curve quickly you can dodge several hits from enemy ships, the acceleration is also not bad.

Armament

Primary armament

2 х Turret40 mm Bofors L/60 Mark 3 gun

Ammunition2000 rounds

Belt capacity4 rounds

Fire rate160 shots/min

Vertical guidance-6° / 90°

The main armament consists of only two single 40mm guns positioned one in the front and one in the back of the Motor gun boat, this armament is pier good against almost any enemy target, thanks to the selection of shots and penetration, the belt HE very useful for destroying light targets such as other coastal ships and enemy aircraft, while the belt AP even though it causes little damage can penetrate even motor torpedo boats and damage them the main advice is to target the engines to remove the enemy crew faster

Additional armament

Setup 18 x B TG 100 depth charge

The only additional armament that the MS-473 carries are depth charges that are very useless because of the speed of your vehicle and your survivability, but if you happen to have a naval enemy very close to you use them because they will be able to destroy them quickly or create a hole in them that is difficult to repair.

Usage in battles

MS-473 unlike the MS-472 doesn't carry torpedoes which are very useful for any naval target so you'll have to watch out for enemy destroyers and ships with good survivability because your two 40mm don't kill instantly you'll need some time to destroy the enemy target in fact you'll aim to destroy more at enemy coastal ships, instead you need to start learning how to shoot at enemy aircraft being that you are only equipped with main armament then controlled by you, but it is not just the difference of the lack of torpedoes, in fact the MS-473 carries 8 B TG 100 depth charges instead of torpedoes, these charges are always useful against any enemy ship and manages to create holes in the hull of enemy ships that take a long time to be closed, this will be your only armament against ships much larger than you, in the end always try to go out suddenly and shoot at the enemy never frontal collision because if not you can not use the second 40mm in your possession, and remember to check the tide during the game because if you find it calm you will not have problems to aim at the enemy instead if it is moved it will be much more difficult and you will have to adjust your speed to be able to aim well.

Pros and cons

Pros:

• Adeguate armament
• Effective speed and acceleration

Cons:

• No torpedoes
• Mediocre survivability

History

MS 31

Launched on June 18, 1942, CRDA at Monfacone, built and commissioned on June 24, 1942, was assigned to the 2°Squadriglia, transferred to bases in the Sicilian Channel in late July 1942, in the same month specifically on the 12th and 13th participated in operations against the British convoy bound for Malta during the Battle of Mid-August, on the night of August 13, 1943, MS 31, under the command of Lt. Calvani, was in an ambush south of Ras Mustafa, which had intercepted a signal to discover MS 22, found an enemy formation just south of Kelibia, was spotted by enemy ships and retreated only to later attack from 700 meters with torpedoes, the targets whose torpedoes were fired were a destroyer and a steamer, the only target to be hit being the steamer Glenorchy which sank soon after.

Between 1942 and 1943 it participated in various attack, rescue and escort operations, on the date of the armistice MS 31 was in Taranto and remained stationed at that base until October 10, 1943, on the same date it moved to Brindisi joining the reconstituted 1°Flottiglia Motosiluranti, also in the same month with MS 33 and MS 74, it was stationed in Termoli from where it began operations against the Germans in the Adriatic, in which it participated until the spring of 1945.

On the evening of June 19, 1944, under the command of Vessel Scialdone, together with MS 64 she carried out a daring operation to land and recover British saboteurs near Fano. Having carried out the release and recovery of the saboteurs, who had undermined the coastal railroad, she together with MS 64 carried out a firing action against a stationary German military train near the beach, MS 64 and MS 31 fired for a good 5 minutes in which they caused the tank car full of gasoline to explode, and numerous fires on the train after ceasing fire the two units pulled out and headed for Termoli, where they returned the next morning.

After the end of WW2, even though they were to be handed over to the U.S. because of the Peace Treaty, she remained in service with the Italian Navy, after a certain period of inactivity, she became part of the Coastal Forces Group, being employed for exercises in the Adriatic, later transferred to the dependencies of the Gruppo Forze Costiere, in 1957, together with the MS 24, she went into reserve and put under modernization.

MS 473

Before modernization and Italy's entry into NATO, the ship was classified MV-613, after entry renamed MS 613 and eventually after the radiation of the old destroyed units it was named MS 473.

After World War II in 1957 together with MS 24 she was put under modernization, modernization decided by the General Staff consisted only of some modifications to the hull and outfitting, embarkation of new more powerful engines specifically CRM 185-ASM of 1500 HP and eventually outfitting with more modern and efficient armaments.

The MS 473 was modernized by removing 2 front 553mm torpedo launchers, and 2 side 450mm pulse launchers, the 20/65mm Breda towers present in the torpedo boat were replaced with single 40mm Bofors guns.

After various training activities and coastal control missions, MS-473 was decommissioned in Taranto on Dec. 1, 1974, decommissioned on Oct. 1, 1975, and transferred, was not scrapped instead was repainted and placed in the Naval Historical Museum in Venice.
