The GIS 811 was originally laid down in 1943 as PT-388 by Robert Jacob Consolidated Shipyard, City Island, NY, launched and completed in 1944, and delivered to the British Navy as MTB-400 to reinforce patrol, reconnaissance and defence capabilities to Allied naval convoys until the end of WWII. It was later given back to America, who sold her to Italy to help rebuild the Italian flotilla. The Italian Navy later changed the armament, improving it to a 20 mm/65 Breda cannon and a 2 cm/65 Flakvierling 38 quad turret, and it served training and patrol missions until 1959 when it was decommissioned.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Italian motor torpedo boat {{Battle-rating}}. It was introduced in [[Update "Starfighters"]].
+
Introduced in [[Update "Starfighters"]], the Vosper 70' GIS 811 is a nimble little coastal boat with highly effective armament that can easily make short work of any other coastal boats it gets its eyes on. It's one of the first boats you'll unlock when playing the Italian naval tree. However, due to how the armament is placed, you need good map knowledge and know how to position yourself to make the most out of the vehicle. This version in game represents one of the early post-war motor torpedo boats the Italian navy had put into service.

The Vosper 70' GIS 811 sadly is not very armoured, although it can withstand some machine-gun fire, most naval boats you'll encounter will not need much to take you out. The boat can take some damage if you don't expose yourself entirely, which should give you enough time to either move out of the way or fire back. Enemy aircraft with cannons and bombs also will be a big problem, so try avoid getting hit by them as you dont have much armour when being attacked from the air.

The mobility of the Vosper 70' GIS 811 is very good, although their may be some ships which will slightly be faster you have just enough to usually be in front of most of your team. With this you're able to get to positions or get out of danger when you no longer feel safe. The mobility at times can also be a bit too much and unexperienced players may crash into other ships or beach themselves, thankfully you can regulate the speed of the Vosper 70' GIS 811 if needed.

With the creation of NATO, the peace treaty was no longer valid and with this GIS-811 was redesignated as '''MS-811''' Motor Torpedo Boat then again renamed '''MS-461''', in the last years she would carry out exercises and patrols until 30 June 1959 when she was decommissioned.

Description

The GIS 811 was originally laid down in 1943 as PT-388 by Robert Jacob Consolidated Shipyard, City Island, NY, launched and completed in 1944, and delivered to the British Navy as MTB-400 to reinforce patrol, reconnaissance and defence capabilities to Allied naval convoys until the end of WWII. It was later given back to America, who sold her to Italy to help rebuild the Italian flotilla. The Italian Navy later changed the armament, improving it to a 20 mm/65 Breda cannon and a 2 cm/65 Flakvierling 38 quad turret, and it served training and patrol missions until 1959 when it was decommissioned.

Introduced in Update "Starfighters", the Vosper 70' GIS 811 is a nimble little coastal boat with highly effective armament that can easily make short work of any other coastal boats it gets its eyes on. It's one of the first boats you'll unlock when playing the Italian naval tree. However, due to how the armament is placed, you need good map knowledge and know how to position yourself to make the most out of the vehicle. This version in game represents one of the early post-war motor torpedo boats the Italian navy had put into service.

General info

Superstructure15 mm (wood)
Number of section3
Displacement37 t
Crew16 people

The Vosper 70' GIS 811 sadly is not very armoured, although it can withstand some machine-gun fire, most naval boats you'll encounter will not need much to take you out. The boat can take some damage if you don't expose yourself entirely, which should give you enough time to either move out of the way or fire back. Enemy aircraft with cannons and bombs also will be a big problem, so try avoid getting hit by them as you dont have much armour when being attacked from the air.

Mobility

Speedforward / back
AB104 / 35 km/h
RB74 / 25 km/h

The mobility of the Vosper 70' GIS 811 is very good, although their may be some ships which will slightly be faster you have just enough to usually be in front of most of your team. With this you're able to get to positions or get out of danger when you no longer feel safe. The mobility at times can also be a bit too much and unexperienced players may crash into other ships or beach themselves, thankfully you can regulate the speed of the Vosper 70' GIS 811 if needed.

Additional armament

Setup 12 x 450 mm steam turbined W.200/450X5,75 torpedo
Main article: W.200/450X5,75 (450 mm)
The additional armament consists only of two 450mm torpedo launchers, which allow the destruction of tougher targets to destroy such as destroyers, frigates or other ships with good survivability, of course, try to aim the torpedoes at enemy ammo racks.

Usage in battles

The GIS 811 allows you to quickly reach very good positions to flank the enemy so that you can use all the armament in your possession, always try to position yourself so that you can use all the main armament composed of Italian 20mm and four German 20mm these guns can cause serious damage to enemy coastal ships, while if you find a stronger target with good survivability use torpedoes aiming them at the ammo rack usually under the main towers, remember not to go in frontal because you have little crew and little survival in general because of the hull Vosper is not armoured, you will have some difficulty in shooting down enemy aircraft because they could use rockets and destroy you in one shot, at the end that is also the problem of the tide that makes it difficult to aim in rough water and then you will have to try to hit the enemy the best way possible

Pros and cons

Pros:

  • Effective 20 mm guns
  • Sufficient AA capability
  • Small enough to hide behind rocks, islands, etc.
  • Torpedoes have a lot of explosive filler
  • Capable of destroying other coastal boats very quickly
  • Sufficient speed and mobility

Cons:

  • Torpedoes have a short range
  • Guns are insufficient against bigger boats
  • Susceptible to even small arms fire
  • Extremely low survivability

History

Laid down on 18 August 1943 as PT-388 by the Robert Jacob Consolidated Shipyard, City Island, NY, launched on 17 December 1943, completed on 13 June 1944 and then transferred to the British Navy and renamed HMS MTB-400 it was used for reconnaissance, patrol and escort missions.

After the Second World War it was transferred back to the US Navy on 16 October 1945 then in the following month decommissioned, but this time it was handed over to the State Department, Foreign Liquidation Commission in January 1948, whose motor torpedo boat was purchased by the Italian Navy and transferred on 24 March 1948 and under the peace treaty of World War II renamed GIS-001 and rearmed with new armament with a 20 mm/65 Breda (20 mm) and a quad tower with 2 cm/65 Flakvierling 38 (20 mm), she was used as a torpedo recovery boat, then immediately renamed GIS-811.

With the creation of NATO, the peace treaty was no longer valid and with this GIS-811 was redesignated as MS-811 Motor Torpedo Boat then again renamed MS-461, in the last years she would carry out exercises and patrols until 30 June 1959 when she was decommissioned.
