Ha-Go (mod. 1)

2022-11-22T20:12:35Z

U49380419: Again, changes over recommended belts for the secondary 20mm twin cannons. APT belts appear much more effective at close range, killing ships within seconds. Primary armament section and recommended playstyle sections have also both been adjusted.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Japanese motor gun boat {{Battle-rating}}. It was introduced in [[Update 1.89 "Imperial Navy"]].

== General info ==
=== Survivability and armour ===
{{Specs-Fleet-Armour}}

The hull of the Ha-Go is made up of 6 mm steel, with no additional armour protection. In addition, it only has a crew of 10, which overall does make it a fairly weak vessel. It is quite low down in the water, which may cause enemy boats to miss the hull at the longer ranges but this really is the only passive advantage the Ha-Go has in terms of survivability. At the closer ranges though the vast majority of enemy vessels will be able to tear through the hull of the Ha-Go fairly easily, it's also very vulnerable to high calibre cannons as well, and can be hull broken if it takes a shot from one of these cannons.

=== Mobility ===
{{Specs-Fleet-Mobility}}

The speed and mobility of this vessel is notably one of its weakest assets, it can reach 34 km/h in AB and 25 km/h in RB. It's fairly unresponsive to changes in speed but not necessarily changes in direction, it takes a long time to accelerate and decelerate but it can turn and change direction fairly easily, which is useful for maintaining angles of attack for the weaponry. The main detriment relative to the speed though is in regards to its survivability, as this vessel is relatively unarmoured, large and slow for its battle rating, it accumulates a lot more damage due to the slow speed, this unfortunately makes it a very easy vessel to hit and critically damage.

{{Specs-Fleet-Primary}}

{{main|Type 97 (57 mm)}}
[[File:Ha-Go Fighting Boat Model 1 (2).jpg|thumb|528x528px|The Ha-Go Fighting Boat Model 1]]
This boat is equipped with the 57 mm Type 97 cannon, which is functionally very similar to that found on the I-Go Ko and Chi-Ha tanks, though it has some slight ballistic differences. For the Ha-Go though it's a fairly underwhelming weapon for a primary. It will do significant damage to smaller boats when the shot lands but landing a shot is the hardest part. It comes with three different rounds:

* HE - Decent damage output over a fairly wide area
* HEAT - Higher damage output over a condensed area, with lower velocity
* APHE - Very little damage potential due to low explosive mass

Overall the stock HE round is the most consistent to use at range, dealing a fair amount damage, blacking out compartments on smaller boats with a single hit. The HEAT contains more explosive filler, and is optimal against more armoured targets, but it doesn't spread its damage like the HE shell does. Due to its lower muzzle velocity, it can be difficult to aim, but a few shells will knock out any small ships you face. The APHE is close to useless functionally, it contains less than half the explosive filler compared to the HE and does a very little amount of internal damage, use HEAT instead if you are facing armoured targets.

=== Secondary armament ===
{{Specs-Fleet-Secondary}}

{{main|Type 98 (20 mm)}}

The Ha-Go is equipped with twin 20 mm Type 98 cannons for its secondary weapon. These cannons perform very well against aircraft and boats alike, however they can't fire directly forwards, as the cabin blocks the line of sight. All in all, its a modestly powerful weapon and more reliable than the primary 57 mm gun. The magazine for each cannon contains 20 rounds and reloads very quickly, allowing for a steady stream of fire against enemy vessels or aircraft. It comes with three belts:

* Universal - A mix of high explosive and armour piercing rounds.
* HET - Majority high explosive rounds
* APT - Majority armour piercing rounds

While HET rounds remain more viable over longer ranges, and against aircraft, APT rounds contain much higher killing potential at close range (<u><</u>1km) due to their ability to quickly destroy compartments. This is especially important as the Ha-Go is very vulnerable to close range machine gun fire and autocannon fire in general due to its exposed crew compartment, and will quickly lose out in longer engagements. Bring both APT and HET belts, swapping between the two for maximum efficiency.

=== Additional armament ===
{{Specs-Fleet-Additional}}

{{main|Type 3 depth charge}}

The Ha-Go can carry eight Type 95 depth charges, which can be dropped to maim other naval targets, they have rather limited viability though as most MTBs will be able to outrun the explosion. However they are useful in the event of being rushed by a smaller naval vessel, as if the drop is timed right the depth charges can easily take out enemies performing this manoeuvre.

== Usage in battles ==

[[File:Ha-Go Fighting Boat Model 1 (1).jpg|thumb|606x606px|Ha-Go Fighting Boat engaging an enemy LS class vessel]]
A very important aspect of staying afloat in the Ha-Go is to not actively make yourself a target, if this boat is caught out in the open it will be very easy for enemy vessels to hit, as it's so slow and unarmoured, a single high calibre cannon round will break the hull, and autocannon fire will steadily chew through the hull and crew members. Open water is a very dangerous place to be in this vessel, it works best around the terrain where it can use the environmental cover. It's a good idea to hug the various terrain on most maps, be it islands or shipwrecks, this way the vessel has some form of constant cover.

It's recommended to play defensively with this boat, due to your slow speed and relative fragility. The twin 20 mm cannons still make for a decent versatile weapon, and can be lethal at close ranges. To maintain cover, it's possible to stick the rear of the vessel out of cover so only the rear compartment and the twin cannons are visible, this way the majority of the vessel is protected from taking fire, and the most effective weapon has a wide area it can cover, and if a dangerous enemy boat appears or you're taking too much fire, you can simply accelerate off out of sight. This vessel has no active defensive qualities, so to make it work effectively, you'll need to negate the negatives of its lack of armour and lack of mobility, staying somewhat sedentary around hard cover from the terrain is one of the most effective ways to do this.

The main 57 mm cannon will do substantial damage to smaller craft if the round connects, but it has very low velocity and is close to unusable in rough seas, on more placid water it can be used somewhat effectively, but most of the time the secondary 20 mm guns will be more effective, and can also tackle enemy aircraft fairly well. The time it takes to range in the 57 mm cannon, isn't really worth its potential damage output, the twin 20 mm guns will deal a constant stream of damage, and are much easier to aim accurately over distance, or for hitting weak spots.

=== Pros and cons ===


'''Pros:'''

* Effective secondary weapon
* Versatile armament options

'''Cons:'''

* Very slow compared to other boats of the rank
* Poor survivability
* Inadequate primary weapon performance

== History ==

Ha-Go Fighting Boat Model 1 (波號戦斗艇一型), also known Se-Ha (せは艇) was one of the first prototypes of small escort boats (小護衛艇) by the Imperial Japanese Army. It was designed to escort "Daihatsu"-class landing crafts that were transporting munitions to offshore islands.

In January 1944, the Imperial Japanese Army 10th Technical Research Institute ordered Hitachi Zosen Sakurajima shipyard to make two types of small escort craft. The first, called Ha-Go Fighting Boat Model 1 "Se-Ha" (Ha-Go meaning "Mark A"), was to be equipped with two 150 hp engines, and a second named the Ha-Go Fighting Boat Model 2 "Se-Ni" equipped with two 60 hp engines.

The Se-Ni was completed in October 1944 but the top speed was only 9 knots so the plan was cancelled. Se-Ha was eventually completed in December 1944, but after trials the engineers decided to try to modify the design to get more speed.

A third design, "Se-Ha Kai" was completed in July 1945. In a trial cruise during October 2-5, its speed reached 13 knots so research ended. By the surrender of Japan, it had not been formally adopted, but would have been officially named the Type 5 Small Escort Boat. ("Type 5" already in game is Large Escort Boat.)

Type T-38

2022-11-22T19:46:59Z

U49380419: Changed the recommended belt after spending many agonising hours using HEI belts, only to discover AP belts were much more effective. At the tier this ship is placed, HEI simply becomes ineffective against most enemies.

}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Japanese motor torpedo boat {{Battle-rating}}. It was introduced in [[Update 1.89 "Imperial Navy"]].

Otherwise known as the Otsu-Gata (Type B), it would be the most produced Japanese dedicated motor torpedo boat offering the most well-rounded package for the Japanese coastal tree. Armed with a single potent 25 mm, depth charges and 2 torpedoes with mobility to boot, it will be the workhorse of the bluewater fleet of any new Japanese naval player.

== General info ==
=== Survivability and armour ===
{{Specs-Fleet-Armour}}

[[File:Type T-38 3.jpg|thumb|left|The Type T-38]]
The Type T-38 doesn't have any armour protection, just 40mm of wood in the construction of the hull. This boat's crew is made up of only 7 members, all contained in the front portion of the vessel, this makes the T-38 very susceptible to being knocked out due to lack of crew. There's very little negative space in this boat, meaning that the vast majority of incoming shots that land will be striking a critical component, either disabling the boat, setting it on fire or cutting down its crew count. All of this combined makes the Type T-38 a very weak vessel, to the point where even small calibre munitions will be able to quickly score fatal damage.

=== Mobility ===
{{Specs-Fleet-Mobility}}


The speed and overall mobility of the Type T-38 is fairly average overall, it can reach a maximum speed of 51 km/h (31 mph) in RB, which is on the slower side for contemporary MTBs and even some light gunboats. It's not amazingly responsive to input either, and will take a decent amount of time to come to a stop, or make a 180 degree turn. It's faster than the large sub chasers and really dangerous ships, so its mobility and speed is enough to get out of trouble if need be, but not really enough to outrun some lighter vessels, or turn tail and escape if you advance too far. This coupled with a poor survivability makes its mobility a rather underwhelming asset.

== Armament ==
{{Specs-Fleet-Armaments}}
[[File:Type T-38 2.jpg|thumb|The Type T-38 engaging an He-111]]

=== Primary armament ===
{{Specs-Fleet-Primary}}

{{main|Type 96 (25 mm)}}

The T-38 is equipped with a single 25 mm Type 96 autocannon, which makes the boat a bane against any boats/ships around its BR range. The cannon has a great fire arc, being able to traverse 360 degrees, which makes knocking out ships sneaking up on your rear a lot easier. Additionally due to the HE this boat can engage targets at range and still do damage. However, the gun is not stabilised and will bounce around a lot in rougher seas, and this combined the slow rate of fire means a lot of your shots will commonly miss, but when a shot lands it will do a lot of damage, this cannon can also cause critical damage to aircraft with only a single hit. The cannon comes with three belts: universal, APT belts and HEI belts.

* Universal belts: good balance between firepower and tracer contents, useful for newcomers to the Japanese 25 mm autocannon.
* APT belts: Full of AP shells. It will struggle to do damage at range, however becomes very lethal up close as it can knock out sections of enemy ships very quickly.
* HEI belts: Trades tracer rounds for extra firepower and stealth. Very good at destroying aircraft, but also useful against unarmoured targets.

It is recommended to take both APT and HEI belts: As a general rule, swap to APT when engaging at below or at 1km, and use HEI when engaging at range or engaging aircraft.

=== Additional armament ===
{{Specs-Fleet-Additional}}

{{main|Type 2 (450 mm)|Type 95 depth charge}}

The Type T-14 is armed with two Type 2 torpedoes, they will easily destroy any large vessel at the lower ranks, but as the maximum range is only 3 kilometers you'll need to get a bit closer to the target or choke point than you would with other torpedoes.

This boat can carry six Type 95 depth charges, which can be dropped to maim other naval targets, they have rather limited viability though as most MTBs will be able to outrun the explosion, however they are useful for sneaking up on the larger ships, as if you can reach them unnoticed one or two of these depth charges will sink the vessel.

== Usage in battles ==

[[File:Type T-38 1.jpg|left|thumb|The Type T-38, engaging a Russian MO-4]]
In the trifecta between survivability, mobility and firepower, the Type T-38 can only rely on one- Firepower. This means it's a good idea to aim to nullify the drawbacks of its terrible survivability, and unimpressive mobility, so try and avoid situations where these aspects come into play. Try not to engage at too close a range, as even vessels with underwhelming armament can cause critical damage to you fairly quickly, mid range is where this boat works best, the 25mm is fairly hard to aim, it has a low muzzle velocity and fires very slowly, because of this you're going to want to get as many shots on target as possible as to not waste potential time on target. At long range your shots will likely miss, and at close range you're going to be taking too much damage, despite how easily you'll be able to aim the gun. Mid range is a good mix between the two distances, as it allows you to land shots somewhat accurately, while also taking less damage. Your mobility wont do you any favors at close range either, other MTBs will be able to outmanuver you very easily, and chances are you wont be able to outrun them.

Due to your 360 degree fire arc you can fire at an enemy from all angles, if you find yourself sailing towards an enemy, turning around and sailing away would be a good choice, you really don't want to be taking hits, and staying further away will minimize the damage you take, while sailing away you can still fire back on whatever vessel is behind you, engaging like this will also somewhat protect your crew compartment as it's in the front, which is the most vulnerable part of the boat. You will likely suffer damages to your engine for engaging like this, but that can be repaired, whereas your crew can't be replenished.

Try playing around islands and avoid sailing in the open with no cover around you, flitting between islands and sight lines will allow for you to be able to retreat into cover when necessary, playing this way will also allow for you to get the jump on enemies, you're going to want to start firing at a ship before it starts firing at you especially when playing the T-38 as it's so weak, and staying out of sight until the last second is a great way of dealing a good initial portion of damage before the enemy returns fire.

=== Pros and cons ===


'''Pros:'''

* Excellent 25 mm gun, can destroy opponents in several direct hits

* Can cause damage to large, armoured vessels
* 25mm cannon can take out aircraft in a single shot potentially

'''Cons:'''

* Unimpressive mobility
* Poor survivability, even from small calibre rounds
* Small magazine size
