Description

The MTB Vosper 2 series is a rank I British motor torpedo boat with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.83 "Masters of the Sea" as part of the British fleet closed beta test.

General info

Survivability and armour

Vosper 2 series has the following armour layout:

• 20 mm Oerlikon Mk.II gunshield: 12.7 mm hardened armour
• Hull: 24 mm, wood
• Superstructure: 15 mm, wood

Vosper 2 series internals (starboard side). Note the ammo storages below the bridge.

Any gun in the game will easily be able to penetrate anywhere on the boat, including the gunshield, at practically any range. Vosper 2 series can also be hull-broken by any gun larger than 4 inches (102 mm). Luckily though, at her battle rating, the only gun that can hull-break Vosper 1 series is the 8cwt QF Mk I (114 mm), found on Dark Adventurer. These are traits of the vast majority of boats in tier I and II though, so they aren't really a disadvantage.

The hull is split into three compartments. The first compartment starts at the bow and ends just in front of the forward gun mounts. The second starts at the forward gun mounts and ends in front of the engines. The third starts at the engines and ends at the stern. Overall, with a crew complement of 12, survivability is average.

Of note are the ammo storages located just underneath the bridge. Destroying these will also destroy the rest of the boat. In practice, though, this almost never happens, since most guns at this battle rating are either machine guns or low-calibre autocannons which require a large number of hits to destroy the ammo storages. It's both faster and easier to just target the hull compartments and knock out the crew.

Armament

Primary armament

In her main armament group, Vosper 2 series has one 20 mm Oerlikon Mk.II in a single mount, mounted centerline in front of the bridge. It has 1,980 rounds of ammunition available. The mount can traverse horizontally at a rate of 75°/s and vertically at a rate of 75°/s. The gun has a belt capacity of 60 rounds and has a rate of fire of 450 rounds/min. With a stock crew, the guns can be reloaded in 5.2 seconds; with an aced crew, they can be reloaded in 4 seconds. Their maximum range against surface targets is roughly 2.1 km.

There are three choices of ammunition available:

• Universal: HEF-T/HEF-I/AP-T

• 20 mm HE: HEF-T/HEF-I/AP-T/HEF-I

• 20 mm AP: AP-T/AP-T/AP-T/HEF-I

20 mm AP	39	36	29	23	20	17

Secondary armament

In her secondary armament group, Vosper 2 series has two 12.7 mm Vickers Mk.V guns in a twin mount, mounted centerline behind the bridge. It has 5,200 rounds of ammunition available, 2,600 rounds per gun. The mount can traverse horizontally at a rate of 75°/s and vertically at a rate of 75°/s. Each gun has a belt capacity of 200 rounds and has a rate of fire of 600 rounds/min. For some reason, the gun on the gunner's right side fires at a faster rate of fire, around 700 rounds/min, firing all 200 of its rounds in the time it takes the left side gun to fire about 170 rounds. With a stock crew, the guns can be reloaded in 5.2 seconds; with an aced crew, they can be reloaded in 4 seconds. Their maximum range against surface targets is roughly 2.1 km.

Torpedo armament

Vosper 2 series has two torpedo tubes, one on each side of the bridge, and can carry two 533 mm Mk.VIII torpedoes. The torpedo tubes are pointed forwards, but they are angled outwards on each side and are fixed, requiring the boat to be turned in order to aim them.

The Torpedo Mode modification is available as a tier IV modification. Installing it has the following changes:

Special armament

Vosper 2 series can carry four Mk.VII depth charges just behind the bridge, three on each side facing outwards. The depth charges are dropped one at a time and drop in this order:

1. Portside, foremost
2. Starboard side, foremost
3. Portside, aftmost
4. Starboard side, aftmost

Before spawning, the detonation time delay can be set anywhere between 3 seconds and 10 seconds.

Usage in battles

The main purpose of the MTB Vosper(2) is to use its torpedoes to sink other ships as this is where the most damage will occur. Though outfitted with a 20 mm autocannon and two 12.7 mm machine guns, these weapons are meant to be used as a backup or to finish off an already damaged ship. Attempting to take on a fresh ship with these guns will require the expenditure of most of the ammunition available. The damage difference between available ammunition types is negligible. Best bet is to utilize the 20 mm autocannon at ranges above 1,500 m while the 12.7 mm machine guns are a better fit and hit harder when in at closer ranges.

Pros and cons

Pros:

• Powerful 20 mm with 40 mm of penetration for the AP round at range (+1,500 m)
• Good speed
• The twin turret with 12.7mm is much powerful than the quadra 7.7 mm
• Generous matchmaking

Cons:

• No armour
• Only two torpedoes
• 20 mm cannon less effective at closer range (under 1,500 m)

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 big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.

Media

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
