MGB-75 has the following armour layout:
 +
 +
* [[2pdr QF Mk.IIc (40 mm)|2pdr QF Mk.IIc]] gunshield: 12.7 mm hardened armour
 +
* [[Oerlikon Mk.V (20 mm)|Oerlikon Mk.V]] gunshield: 12.7 mm hardened armour
 +
* Hull: 40 mm, wood
 +
* Superstructure: 15 mm, wood
 +
 +
[[File:MGB-75_internals.png|thumb|MGB-75 internals (starboard side).]]
 +
 +
Any gun in the game will easily be able to penetrate anywhere on the boat, including the gunshields, at practically any range.
 +
 +
MGB-75 can be hull-broken by any gun with a diameter greater than 4 inches (102 mm). Hull-break triggers when a capable gun destroys any hull compartment or the bridge, resulting in instant destruction of the rest of the boat. At MGB-75's battle rating, the only guns capable of hull-breaking her are the [[8cwt QF Mk I (114 mm)|8cwt QF Mk I]], found on {{Specs-Link|uk_dark_class}}, and the [[10.5 cm SK C/32 (105 mm)|10.5 cm SK C/32]], found on {{Specs-Link|germ_artilleriefahrprahm_typ_d3}}. The ability to be hull-broken by guns larger than 4 inches is a trait that applies to the vast majority of boats in tier 1 and 2, so in that respect, MGB-61 isn't better or worse than most other boats.
 +
 +
MGB-75's hull is split into three compartments. The first compartment starts at the bow and ends just in front of the forward gun mount. The second starts at the forward gun mount 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.
 +
 +
MGB-75 has 4 fairly large ammunition storages, two in front of the fore [[2pdr QF Mk.IIc (40 mm)]] mount and two in front of the rear [[Oerlikon Mark V (20 mm)]] mount, housed in the superstructure. Destroying these will also destroy the rest of the boat.
 +
 +
<!--In practice, though, this almost never happens, since they are relatively small targets and because most guns at this battle rating are either machine guns or low-calibre autocannons which require many hits to destroy ammo storages. It's often both quicker and easier to target the hull compartments and knock out the crew.-->

In her anti-aircraft armament group, MGB-75 has four 7.72 mm Lewis machinegun 1916s in two twin mounts, one on either side of the bridge. For each mount, there are 1,940 rounds of ammunition available, 970 rounds per gun, for a total of 3,880 rounds. There are no stated horizontal or vertical traverse rates given in-game, but the mounts handle very similarly, if not exactly, like other twin and quadruple 7.72 mm Lewis machinegun 1916 mounts which can traverse horizontally at a rate of 75°/s and vertically at a rate of 75°/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. Their maximum range against surface targets is roughly 1.6 km.

;Ammunition Choices
 +
 
 +
For the 40 mm 2pdr  QF Mk.IIc cannon, the best ammunition choice is the 40 mm HE because it has the highest ratio of HE rounds to AP rounds, meaning that it will be the most effective against both aircraft and surface targets. The 40 mm HE belt should be the main ammunition choice, but a few of the 40 mm AP belt should also be taken into battle for use against armoured targets.
 +
 
 +
For the 20 mm Oerlikon Mk.V cannons, the best ammunition choice is the 20 mm HE. There isn't much of a point in using the 20 mm AP belt because the primary armament is much more suited for engaging armoured targets anyway.
 +
 
 +
;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, especially since, if they're not dropped, they essentially become unarmoured ammo racks.

Description

GarageImage MGB-75.jpg


The 71 ft MGB-75 is a premium rank II British motor gun boat with a battle rating of 2.0 (AB) and 2.3 (RB/SB). It was introduced in Update 1.91 "Night Vision".

General info

Survivability and armour

MGB-75 has the following armour layout:

  • 2pdr QF Mk.IIc gunshield: 12.7 mm hardened armour
  • Oerlikon Mk.V gunshield: 12.7 mm hardened armour
  • Hull: 40 mm, wood
  • Superstructure: 15 mm, wood
MGB-75 internals (starboard side).

Any gun in the game will easily be able to penetrate anywhere on the boat, including the gunshields, at practically any range.

MGB-75 can be hull-broken by any gun with a diameter greater than 4 inches (102 mm). Hull-break triggers when a capable gun destroys any hull compartment or the bridge, resulting in instant destruction of the rest of the boat. At MGB-75's battle rating, the only guns capable of hull-breaking her are the 8cwt QF Mk I, found on Dark Adventurer, and the 10.5 cm SK C/32, found on AF D3. The ability to be hull-broken by guns larger than 4 inches is a trait that applies to the vast majority of boats in tier 1 and 2, so in that respect, MGB-61 isn't better or worse than most other boats.

MGB-75's hull is split into three compartments. The first compartment starts at the bow and ends just in front of the forward gun mount. The second starts at the forward gun mount 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.

MGB-75 has 4 fairly large ammunition storages, two in front of the fore 2pdr QF Mk.IIc (40 mm) mount and two in front of the rear Oerlikon Mark V (20 mm) mount, housed in the superstructure. Destroying these will also destroy the rest of the boat.

Armament

Primary armament

Main article: 2pdr QF Mk.IIc (40 mm)

In her primary armament group, MGB-75 has one 40 mm 2pdr QF Mk.IIc automatic cannon in a single mount, mounted centerline in front of the bridge. It has 1,400 rounds of ammunition available. The mount can traverse horizontally at a rate of 25°/s and vertically at a rate of 25°/s. The gun has a magazine capacity of 56 rounds and has a rate of fire of 200 rounds/min. With a stock crew, it can be reloaded in 7.8 seconds; with an aced crew, it can be reloaded in 6 seconds. Its maximum range against surface targets is roughly 3.1 km.

Secondary armament

Main article: Oerlikon Mk.V (20 mm)

In her secondary armament group, MGB-75 has two 20 mm Oerlikon Mk.II in a twin mount, mounted centerline behind the bridge. It has 4,080 rounds of ammunition available, 2,040 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 60 rounds and has a rate of fire of 450 rounds/min. With a stock crew, it can be reloaded in 8 seconds; with an aced crew, it can be reloaded in 4 seconds. Its maximum range against surface targets is roughly 2.1 km.

Anti-aircraft armament

Main article: Lewis 1916 (7.72 mm)

In her anti-aircraft armament group, MGB-75 has four 7.72 mm Lewis machinegun 1916s in two twin mounts, one on either side of the bridge. For each mount, there are 1,940 rounds of ammunition available, 970 rounds per gun, for a total of 3,880 rounds. There are no stated horizontal or vertical traverse rates given in-game, but the mounts handle very similarly, if not exactly, like other twin and quadruple 7.72 mm Lewis machinegun 1916 mounts which can traverse horizontally at a rate of 75°/s and vertically at a rate of 75°/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. Their maximum range against surface targets is roughly 1.6 km.

There are no choices available. Though not directly stated in-game, there is one tracer round every other round, so the guns most likely fire the standard default ammunition choice of 7.72 mm Lewis machinegun 1916s, which has the following composition:

  • Default: AP/T/AP/T

Special armament

Main article: Mk.VII depth charge

MGB-75 can carry two Mk.VII depth charges mounted amidships, one on each side in front of the twin 7.72 mm Lewis machinegun 1916 mounts facing outwards. The depth charges are dropped one at a time in this order (see the image):

  1. Starboard side
  2. Portside

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

Usage in battles

Ammunition Choices

For the 40 mm 2pdr QF Mk.IIc cannon, the best ammunition choice is the 40 mm HE because it has the highest ratio of HE rounds to AP rounds, meaning that it will be the most effective against both aircraft and surface targets. The 40 mm HE belt should be the main ammunition choice, but a few of the 40 mm AP belt should also be taken into battle for use against armoured targets.

For the 20 mm Oerlikon Mk.V cannons, the best ammunition choice is the 20 mm HE. There isn't much of a point in using the 20 mm AP belt because the primary armament is much more suited for engaging armoured targets anyway.

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, especially since, if they're not dropped, they essentially become unarmoured ammo racks.
