Description

The MTB-1 2 series is a premium rank I British motor torpedo boat with a battle rating of 1.0 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".

These boats served before and during the rise of World War II, Comprising 2 MTB Flotillas

The MTB-1 2 series (Motor Torpedo Boat) is a wooden patrol boat serving as a premium variant of the MTB-1 1 series, both inside the British fast crafts tree. These boats are highly agile and fast, equipped with decent torpedoes and depth charges. There are only several differences between the Series 1 and series 2 but, the main drawback is without a doubt, its armament. The 2 x turrets of 4 x Lewis 1916 machine guns feel outdated and lack the power to quickly dispatch other fast boats.

Thanks to the Premium bonuses this ship can increase the gains of Research Points (RP) and Silver Lions . This boost will come handy while researching early rank on the Coastal fleet tree.

The survivability of the MTB-1 is fairly average considering the small amount of crew, the wooden hull with no armour, and also the poor means of defence.

Sailors need to be aware of the higher threats present in the seas, such as 20 mm automatic cannons, 37 mm cannons, possibly some 100 mm cannons. None of which the MBT-1 can fearlessly withstand. The 12.7 mm heavy machine-guns also demonstrate to be lethal against the MTB-1 2 series.

MTB-1(2) internals (starboard side). Note the ammo storages just in front of the bridge.

MTB-1 2 series has the following armour layout:

• Hull: 24 mm, wood
• Superstructure: 2 mm, steel

Any gun in the game will easily be able to penetrate the hull and superstructure at any practical range.

MTB-1 2 series can be hull-broken by any round with a large enough diameter and a large enough explosive mass. In general, this is limited to HE rounds fired from guns greater than 4 inches (102 mm) in diameter. Hull-break triggers when such a round hits and destroys any hull compartment — or in some cases, the bridge — upon which the rest of the boat is destroyed. At MTB-1 2 series' battle rating, there is only one gun capable of hull-breaking her:

• the 8cwt QF Mk I, found on Dark Adventurer.

The hull is split into three compartments. The first compartment starts at the bow and ends between the pumps and the ammunition storage; the second ends just behind the bridge; and the third ends at the stern.

MTB-1 2 series has one ammunition storage that holds ammunition for both the fore and aft gun turrets. It is located directly behind the forward gun turret just above the waterline. Destroying it will instantly destroy the boat. Note that the ammunition storage says that it contains 7,760 rounds of ammunition; this is most likely a bug, since MTB-1 2 series can only carry a maximum of 3,880 rounds.

A crew complement of only 11, only third to the Italian reserve boat MAS 561 with a crew of 15 and the first place going to the American reserve boat, PT-6 with a complement of 17. The crew skill "Interchangeability" allows for a max of 8 crew losses from the complement of 11. Albeit to a minimum, this improvement could be helpful in a desperate situation.

RB/SB	Stock	53	26	~20.77	~36.73
	Upgraded	61	31	~17.44	~33.15

The mobility is one of the most remarkable aspects of the MTB-01. Despite not having the fastest top speed amongst rank I boats, she is capable to turn tightly and cruise swiftly once finally upgraded. Thanks to the thin wooden structure boosted by 3 engines, the small craft will be able to reach 61 km/h of top speed.

Her reverse speed is decent and when coupled with a good instant stop makes as result, satisfactory control of the boat while in battle. Enabling the captains to retreat efficiently when required, without turning the whole boat.

The aspiring British captains should recognize these early fast boats were not specially conceived for rough blue waters. They will move abruptly up and down on strong waves and bad weather. Difficulting the turrets aiming and possibly the navigation itself. This is notable on some high sea maps. The draft or draught of the boat is considerably shallow so it's one clear indication of reduced seaworthiness and a preferably coastal purpose of the MTB-1 2 series.

MTB-1 2 series has a displacement of 22.4 tons.

The guns are the most insufficient aspect of the MBT-1 2 series. Their range is very short, effective up to approximately 1.500 m. After that, the precision and efficiency drop significantly. Sailors firing these guns to targets on 3 km of distance could feel disappointed by the seeming vanish of their shots at the distance.

The primary armament consists of eight 7.72 mm Lewis 1916 machine guns in two quadruple mounts, one on either side of the bridge. There are 1,940 rounds of ammunition available for each mount, 485 rounds per gun, for a total of 3,880 rounds. Stock, the mounts can traverse horizontally and vertically at a rate of 64°/s; with the "Primary Armament Targeting" modification installed, this is increased to 75°/s. Each gun has a magazine capacity of 97 rounds and a cyclic rate of fire of 550 rounds/min. With a stock crew, the guns can be reloaded in 18.2 seconds; with an aced crew, they can be reloaded in 14 seconds.

The firing arcs for the gun mounts are very good, both of which are able to in all directions except in a small ~47° arc in the direction of the other gun mount. They both traverse relatively quickly and can rotate 360°, so switching direction during an engagement isn't much of a problem. That said, as said before, it's best to angle the hull to show as little of the rear hull compartments as much as possible.

Also, keep in mind that MTB-1 2 series' ammunition is very limited, only being able to carry five reloads per gun, so only fire when you know you can land the shots and make every shot count. Despite the limited ammo, though, it's almost always better to empty out the magazines after each engagement because MTB-1 2 series, along with MTB-1 2 series, has the longest reload of any rank I naval vehicle. Emptying the magazines is done to reload the guns in safety, and while this does waste ammunition, it's certainly better than the alternative of having to reload mid-engagement.

There are three ammunition types available:

• Universal: AP · T · AP · T

This belt offers a 50-50 distribution of armour-piercing and tracer rounds. This belt serves decently but not outstandingly, on both naval and air targets. Although, just like its distribution the efficiency is reduced by 50% depending on what the boat engages. This is because each round will have a different effect on the target since the belt is not dedicated but to all kinds of threats. Let's say MTB-1 attacks an enemy boat, only half of the belt will damage efficiently the target.

This belt is recommendable if the strategy is to be armed for all types of threats. Nonetheless, some captains consider this unwise because low magazine count combined with a long reload time of the Lewis machine guns limit the usefulness and the rapid-fire responses. So instead of this, some prefer a more dedicated belt.

• 7.7 mm AP belt: AP · AP · AP · T

This belt is comprised of a 75-25 distribution. The Armor-piercing bullets being the predominant round inside the belt produce important damage to fast crafts. This should be the favourite belt when attacking other boats. The damage to planes is reduced because the bullets could just pass through the aircraft producing no major damage unless a direct hit to some critical parts as the engine or the pilot.

The small portion of tracer might not be enough to cause any aircraft fire and not suitable to damage boats or ships efficiently. Serving principally as guidance to aiming and ballistics.

• 7.7 mm API belt: IT · IT · IT · AP

As a result, this belt should be fully dedicated to air targets. The incendiary and tracer properties are highly adequate to target planes. Even if the gunners can't achieve a direct hit to anything critical on the aircraft. This belt could ignite on wings and fuel tanks. Anything that can burn, shall burn.

Biplanes as the German He 51 (Family) and early naval bombers such as the Japanese F1M2, are prone to catching fire. It's here when this belt provides its value. Contrastingly, this belt is the least recommendable to fight boats. The armour-piercing properties are poor and the incendiary effect is essentially lost.

Despite the composition of these belts, all are capable of destroying enemy vehicles. Captains are free to test what suits them best.

Additional armament

Setup 12 x 18 inch Mk.XII torpedo

Setup 26 x Mk.VII depth charge

Setup 32 x 18 inch Mk.XII torpedo

6 x Mk.VII depth charge

MTB-1(2) has four possible loadouts:

1. 2x Mk.XII torpedo
2. 6x Mk.VII depth charge
3. 2x Mk.XII torpedo, 6x Mk.VII depth charge
4. Without load

Torpedoes

MTB-1 2 series can carry two 18 inch Mark XII torpedoes. These are carried internally in the aft of the boat and are launched through the transom tail first, i.e. facing forwards.

The 18-inch Mk.XII is fairly average in terms of maximum speed and range, though it has a rather small explosive mass compared to other torpedoes. Still, a hit with the Mk.XII torpedo is more than enough to destroy any boat. Besides that, this torpedo is unnoteworthy.

Torpedo Characteristics
Torpedo Mode	Mass (kg)	Maximum speed in water (km/h)	Travel distance (km)	Depth stroke (m)	Arming distance (m)	Explosive type	Explosive mass (kg)	TNT equivalent (kg)
No	702	50	3.20	1	50	TNT	176	176
Yes		74	1.37

The Torpedo Mode modification is available as a rank IV modification. Installing it will give the following changes:

Torpedo Mode Specification Changes
Max Distance (m)	Max Speed (m/s)
-1829	+7

Once unlocked, sailors can opt for always keeping the Torpedo Mode installed. The higher maximum speed is much more valuable against the fast boats of this tier, and the maps are small enough that the decreased maximum range doesn't really matter. Note that the Torpedo Mode modification on MTB-1 2 series has the opposite effect compared to most other vehicles. Typically, the maximum range is increased at the cost of speed.

If using torpedoes, be aware that, unless already launched, the torpedoes can be shot at, and there is a small chance for them to detonate if destroyed. To avoid this, fire the torpedoes early on — and after reloads in AB — or simply don't take them at all. Torpedoes are a situational weapon, so it's largely down to personal preference whether captains want to take them or not.

Mk.VII depth charges numbered according to their drop order (click to view a larger image).

Depth Charges

There are not many practical reasons to use depth charges. But they usually result in a one-hit kill if used properly, even early destroyers such as the Type 1924 Leopard can be quickly decimated by one depth charge, so this really speaks about the amount of damage they are able to generate. The depth charges can also become a liability during combat; their onboard detonation will usually be fatal to the MTB-1 since they essentially act as exposed ammo racks before they're dropped.

Some will think best to equip all the lethal and useful armaments to battle, while others will prefer to not carry such delicate cargos at all. It's up to the captains to decide if the risk is worth a potential reward.

Their use is also extremely situational, this is because they require the carrying ship to get really close to the target to then release the charges. This means the depth charges won't be the ideal weapon to deal with the usual long-distance engagements. With some luck though, sailing up right next to a slower target and dropping a depth charge can lead to some success. If attempting this, remember the depth charge drop order and set the depth charge time delay to a minimum of 3 seconds, since any higher time delay will only mean that the depth charge will sink further, and thus away, from the target.

The Mk.VII depth charges are carried around the bridge area, three on each side. They are dropped one at a time in the following order:

1. Port, foremost
2. Starboard, foremost
3. Port, centre
4. Starboard, centre
5. Port, aftmost
6. Starboard, aftmost

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

Usage in battles

MTB-1 2 series is, for the most part, identical to her tech tree equivalent, MTB-1(1). She shares many of the same drawbacks — low per-hit damage, low maximum range, and poor survivability — but with one key difference: whereas the gun turrets are mounted on the fore and aft on MTB-1 2 series, they are mounted side-by-side amidships on MTB-1 2 series. This allows MTB-1 2 series to bring all of her guns to bear without having to expose the rear hull compartments at all, greatly increasing her potential survivability. In general, MTB-1 2 series has the exact same playstyle as MTB-1 2 series but with a bit of extra versatility because of the gun mount placements.

During battles, avoid long-distance (+2 km) duels with enemy boats because MTB-1 will likely lose against them. Certain long-distance duels are often in maps as the Black seaport and Mediterranean port. Here one of the capture points will be quite far from the main action. If the MTB-1 attempts to capture it, captains should not forget to avoid distant engagements. A common German enemy; the LS 3, outguns and outspeeds the MTB-1. Despite having a lesser crew, this type of enemy can cause a lot of trouble while the MTB's guns will be ineffective.

Some roles in which the MTB-1 Series 1 can perform:

Sea brawler

This is one of the MTB-1's strengths. With good manoeuvrability, the MTB-1 can surprise enemy boats and open fire really close to them. Using the good turning abilities to try and dodge the enemy's main guns while firing too; working with every cover to become a harder target to hit. Employ the MTB-1's mobility to sneak close and personal, using secondary armaments such as the torpedoes and depth charges to multiply the damage; is here when depth charges and torpedoes take an important role. Big targets such as the R-boots and the VAS 201 are vulnerable to them. Be aware, they can carry depth charges and mines so sometimes is better to use the torpedoes and keep the distance. Perform lighting attacks then retreating with a smoke cover back to allies.

There is also always available the possibility to request a battleship's main calibre artillery. This one is very important if sailors see groups of enemies seizing a point or going through a tight coastal passage. Often this artillery will swing apart the fragile and light boats. Pretty remarkably sighting indeed!

Close-range aircraft interception

The MTB-1 2 series can be used to intercept enemy planes, flying boats, and bombers flying low towards allied shipping. Considering these planes sometimes will be slow, the work is pretty much doable for the MTB-01 (The guns provide immediate sustained fire, enough to track and fix the leading). If about to be attacked by an enemy plane, the MTB-1 can disengage, turn in the opposite direction and use a smoke cover to defend. This tactic is also valuable if is needed to protect an allied ship. Thanks to the decent turret range and mobility, the MTB-1 could always keep the enemy plane at gunpoint.

An important thing to remember is to avoid firing planes out of range. This often could lead to several planes attacking overwhelmingly since the location of the MTB-1 got exposed by its own tracers. It could be wiser to wait for a closer enemy approach before opening fire.

With these tactics, captains could additionally appeal for the speed and the small silhouette, attempting to avoid combat not only staying behind the allied side of the map but often going after the allied boats and ships; providing fire support and also repairing any bigger squadmate in need. Any sort of indirect fire without taking damage is the goal. Help maintain capture points or help attack points then fall back when necessary.

• On arcade, the torpedoes are particularly useful in close maps such as Andaman sea or African gulf. There MTB-1 can constantly reload torpedoes and keep launching them in numerous directions. Such as capture zones and the enemy's spawn zones; something should eventually get to them. Don't forget the disponibility of torpedo mode.
• Don't forget to destroy the whole enemy's compartments (coloured black once destroyed). Proceed to fire on other areas of the boat, once a compartment has been destroyed. This means the ammo of the MTB-1 will be used efficiently while exposing the boat to the minimum amount of damage.
• If the MTB fires at a single section of the enemy boat, is unlikely it will be destroyed. Scatter the fire tactically.
• Always angle the hull to show as little of the sides and rear and possible.
• Stick to close-range engagements so that the guns' low maximum range isn't an issue.

Pros and cons

Pros:

• Relatively large magazine capacity: can destroy most opponents without needing to reload
• Placement of guns allows all guns to fire directly ahead
• Large volume of fire can quickly take down low-flying aircraft
• Third best crew count among reserve boats
• Due to large spaced compartments, it can survive relatively well
• Now is possible to target all guns to stern and bow; unlike the MTB-1 1 series
• Premium bonus allows good rewards
• 6 depth charges, 2+ compared to the MTB-1 1 series

Cons:

• Only armed with small-calibre guns: low damage output per gun and low maximum range
• Longest reload of any reserve boat
• Relatively weak torpedoes (low explosive mass compared to other similar torpedoes)
• Guns are severely outranged by most of the other Rank I boats (+1.5 km)
• The ability to fire with all guns to both port and starboard is reduced; compared to the MTB-1 1 series
• Big target compared to other smaller reserve boats; it receives a lot of fire

History

Though the Royal Navy had operated a small number of coastal boats during the first World War, by the 1930s, these flotillas had long been dissolved and the Royal Navy had yet to construct any more. The first two coastal boats since WWI were ordered on 27th September 1935 by the Royal Navy, the order being given to British Power Boat Company based at Hythe, a town near Southampton. In addition to this initial order, four more were ordered on 19th October 1935. These six boats were completed by November 1936, and, with their commissioning on 27th April 1937, the Royal Navy Coastal Forces was founded. Following this, three more boats were ordered on 7th December 1936 and nine more on 11th January 1938. In total, 18 boats were ordered, all of them being completed by 1939.

These boats had a standard displacement of 18 tons and had a length of 60 ft. 4 in., a width of 13 ft. 4 in., and a drought of 2 ft. 10 in. at standard displacement. They were powered by three Napier Sea Lion petrol engines, each driving a single shaft, and could reach speeds of around 30-35 knots. Each boat could carry two 18 inch torpedoes which were stored internally on rails above the engines. On the stern were two more rails that could be folded down to the transom, extending the torpedoes' rails outside of the boat. The torpedoes fired facing forwards down the rails, after which the boat that fired them would have to turn to evade their path. In addition to torpedoes, the boats were also armed with a number of depth charges and, depending on the exact boat, up to eight Lewis guns.

MTB 1, the first of the boats, was redesignated MTB 7 in 1937. Similarly, MTB 7 was redesignated MTB 1 in the same year. In 1938, the former MTB 1, now MTB 7, was redesignated MTB 13. At the same time, MTB 13 was redesignated MTB 7. Finally, later in 1938, the former MTB 1, now MTB 13, was again redesignated MTB 19. Thus, by the start of WWII, the boats were numbered MTBs 1-12 and 14-19 and formed two MTB flotillas: 1st MTB Flotilla, consisting of MTBs 1-6 and 14-19; and 2nd MTB Flotilla, consisting of MTBs 7-12.

The 1st MTB Flotilla was sent to the Mediterranean at the start of WWII and was based at HMS Vulcan in Malta. They were soon recalled back to England in December 1939 to be based at HMS Beehive, Felixstowe, though MTB 19 was sent to HMS Vernon, Portsmouth. Along the way back, due to bad weather, MTB 6 had to be foundered. After they arrived, the remaining boats continued to operate in the English Channel until they were either lost or replaced. Those lost were MTBs 15, 16, and 17, all of which were mined in 1940.

The 2nd MTB Flotilla was commissioned in 1938 and assigned to HMS Tamar, Hong Kong. They were all lost during the Battle of Hong Kong in December 1941. MTB 8 was bombed by IJN aircraft and was damaged beyond repair, and MTB 12 was sunk in action by IJN landing craft. The remainder of the 2nd MTB Flotilla was scuttled on 26th December 1941.
