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".
General info
Survivability and armour
MTB-1 2 series has the following armour layout:
- Hull: 24 mm, wood
- Superstructure: 2 mm, steel
_internals.png)
MTB-1 2 series sports no real armour. Any gun will easily be able to penetrate anywhere on the boat at practically any range. She 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 MTB-1 1 series is the 8cwt QF Mk I (114 mm), found on Dark Adventurer. These are common traits for most boats in tier I and II though, so they aren't really a disadvantage.
The hull is split into three compartments, all of which need to be destroyed in order to knock out MTB-1 2 series. Overall, with a crew complement of 11, survivability is average.
Of note though are two ammo storages just in front of the bridge. These are a relatively large target, especially when firing at the side, destroying just one will instantly knock out the rest of the boat. However, in practice, this tends to not be much of a problem, 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.

Compared to other motor torpedo boats in tier I, MTB-1 2 series is the slowest. She is also quite heavy for her size, with a total displacement of 22.4 tons.
Armament
Primary armament
In her main armament group, MTB-1 2 series has two quadruple 7.72 mm Lewis machinegun 1916 mounts above the bridge, for a total of 8 guns. For each mount, there are 1940 rounds of ammunition available, 485 rounds per gun, for a total of 3880 rounds. They can traverse horizontally at a rate of 64°/s and vertically at a rate of 64°/s. Each gun has a magazine capacity of 97 rounds and has a 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.

MTB-1 1 series can carry six 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 (see the image):
- Portside, foremost
- Starboard side, foremost
- Portside, middle
- Starboard side, middle
- Portside, aftmost
- Starboard side, aftmost
Before spawning, the detonation time delay can be set anywhere between 3 seconds and 10 seconds.

Usage in battles
MTB-1 2 series' main armament only consists of low-calibre machine guns, so the damage output per hit is very low, although this is somewhat alleviated by the fact that she has 8 such guns. Regardless, the guns will always be limited by their low maximum range, roughly 1.6 km. Despite their deficiencies, the guns have a relatively large magazine size of 97 rounds, and, with a rate of fire of 550 rpm, MTB-1 2 series can sustain about 10.58 seconds of fire. Assuming that all the shots are well-aimed, this is more than enough to destroy most boats at this tier without having to reload, unlike some other reserve boats, the G-5 and the Type T-14, which both have to reload once or more to destroy most targets. Be careful though, since MTB-1 2 series has one of the longest reload times at this tier. Because of this, it's always better to empty the magazines after each engagement so that the maximum amount of ammunition is available for the next engagement.
The firing arcs for the gun mounts are very good, both of which are able to in all directions with the exception of 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, when engaging enemies, it's best to keep them either directly in front or directly behind MTB-1 2 series so that the sides of the boat aren't shown.
- Ammunition Choices
The best ammunition choice is the 7.7 mm AP belt since it has the highest ratio of AP to T rounds. While the 7.7 mm API belt may look tempting because of the incendiary tracer rounds, the IT rounds are actually stopped by most wooden hulls and rarely start fires, if ever. This belt is the best to use against aircraft, though with such a long reload to switch to it and such a minuscule difference, there isn't much of a point in using it in that role either.
- Torpedoes
The 18-inch Mk.XII is fairly average in terms of maximum speed and range, but it has a very low TNT equivalence compared to other torpedoes at this tier. Still, a hit with the Mk.XII torpedo on any boat at this tier is more than enough to destroy it. Otherwise, this is torpedo is unnoteworthy.
The Torpedo Mode modification should always be installed. The higher maximum speed is much more valuable against the fast-moving boats of tier I and II, and the maps are small enough that the reduction to the maximum range doesn't really matter.
- Depth Charges
Being anti-submarine weapons and with the present lack of submarines in the game, there is practically no reason to use them. While they can be used against surface targets, this is extremely situational. Sailing up right next to a slower target and dropping a depth charge can lead to some success, though again, this is very situational. If attempting this, remember the order in which the depth charges drop and that there is no reason to use any depth charge activation time setting above the minimum 3 seconds, since higher delay times means the depth charge will sink further, and thus away, from the target. Again, it should be reiterated that this is very situational.
There is no practical reason to take them into battle, since, if they're not dropped, they essentially become unarmoured ammo racks.

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 coastal boats. The first two coastal boats since WWI were ordered on 27th September 1935 by the Royal Navy and given to British Power Boat Company at Hythe, a town near Southampton. In addition to this 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 were boats were ordered, with all of them 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 that were stored on rails above the engines. On the aft 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 them. In addition to torpedoes, the boats were also armed with a number of depth charges and, depending on the 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 Malta at the start of WWII and served with HMS Vulcan. They were soon recalled back to England in December 1939 to be based at Felixstowe with HMS Beehive, though MTB 19 was sent to HMS Vernon at Portsmouth Along the way back, due to bad weather, MTB 6 had to be foundered. 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 mined in 1940.
The 2nd MTB Flotilla was commissioned in 1938 and assigned to Hong Kong with HMS Tamar. They were all lost during the Battle of Hong Kong in December 1941. MTB 8 was bombed by IJN aircraft and was lost, and MTB 12 was sunk in action by IJN landing craft. The remainder of the 2nd MTB Flotilla was scuttled on 26th December 1941.
