=== Survivability and armour ===
+
=== Comparison with analogues ===
''Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.''
+
<!-- ''Give a comparative description of cannons/machine guns that have firepower equal to this weapon.'' -->
 +
The Ho-103 is one of the weakest aircraft HMGs in War Thunder.
  
== Armaments ==
+
Projectile mass (and thus explosive/incendiary payload) is lower than both the American .50 BMG and the German 13x64B cartridges. Muzzle velocity is slightly higher than the German MG 131, but over 100 m/s lower than the American M2. The low mass and low velocity reduce the effective range of the weapon and increase the necessary angle for bullet drop compensation.
=== Offensive armament ===
 
<!--''Describe the offensive armament of the aircraft, if any. Describe how effective the cannons and machine guns are in a battle, and also what belts or drums are better to use. If there is no offensive weaponry, delete this subsection.''-->
 
{{main|Browning M2 (12.7 mm)|Browning (7.62 mm)}}
 
  
* 2 x 12.7 mm (0.5 in) Browning AN/M2 machine guns (470 rounds)
+
The Ho-103 is nose-mounted and synchronized in many Japanese aircraft, cutting the fire rate in half. The result is a machine gun that fires a weak cartridge with high drop and a short effective range at as little as half the fire rate of its contemporaries.
* 4 x 7.62 mm (0.3 in) Browning machine guns (1960 rounds)
 
  
=== Suspended armament ===
+
== Usage in battles ==
<!--''Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.''-->
+
<!-- ''Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.'' -->
{{main|AN-M64A1 (500 lb)}}
+
* Due to the low velocity, it is often impractical to use the Ho-103 at anything other than close range
 
+
* The low damage output and (frequently) low fire rate means a sustained burst is generally required to disable a target.
* 1 x AN-M64A1 500 lb bomb
+
* The typically low ammunition count of Japanese aircraft using the Ho-103 means that ammunition must be conserved judiciously.
<!--
+
* The Default and Tracer belts should not be used if possible. The lack of explosive incendiary bullets greatly reduces damage dealt.
=== Defensive armament ===
 
''Defensive armament with turret machine guns or cannons, crewed by gunners. Examine the number of gunners and what belts or drums are better to use. If defensive weaponry is not available, remove this subsection.''
 
-->
 
== Usage in the battles ==
 
<!--''Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''-->
 
he most plausible manner to use this aircraft is in the Boom & Zoom role, given its fast speed in a dive. In addition, the nose-mounted .50 calibre can help you preform certain attacks a P-40E pilot could dream of doing. However, there are certain methods to using the plane, as it is an earlier iteration of the H-81A-2 is a P-40.
 
 
 
The first method is to climb to altitude, and try to intercept enemy attackers and bombers. This tends to play in favor of the H-81A-2, due to its excellent top speed of 528 kph (328 mph) at 3,800 meters (12,467 feet.) That being said though, you are inhibited by its relatively slow rate of climb of only 10 meters/second (32 feet/second.) On the contrary, once you reach altitude, Boom & Zoom as much as you want against bombers, as your high dive speed will make it difficult for most gunners to target you. In addition, you have a nice turn speed of 21 seconds, which can allow you to snap over on some opponents with relative impunity. If you do find yourself fighting in the vertical, flaps will also be of use to you, as they do have a decent speed tolerance before they snap off.
 
 
 
====Specific enemies worth noting====
 
<!--Some concerning vehicles to worry about if playing this plane. (i.e. Japanese fighters will out turn you)-->
 
Perhaps the biggest threat comes from facing any Japanese plane at this battle rating. They can turn so much faster than you as to bleed your speed and energy to the point of stalling out. The greatest threats come from the Ki-44s and the A6M2-N. In addition, the Ki-43 has significantly greater maneuverability than you. The vast majority of these planes have guns similar in caliber to a .50 Cal, which means that they have the firepower to dispatch you at a fairly fast rate.
 
 
 
In terms of the British, any Spitfire or Hurricane will out-turn you. While they do not have as heavy of armament as you do, the shear rate of fire from the .308s can light up exposed ares of the plane, or even score a pilot kill. While it is mostly unlikely, the Spitfire Mk. IIb not only boasts maneuverability, but also two 20 mm Hispano cannons, which can tear you to bits. In addition, almost all British fighters can out-climb you, which leaves you at a disadvantage in energy.
 
 
 
The Germans have the most planes that can give you a problem, due to the vast majority of them having 20 mm cannons. Most notably are aircraft like the Bf-110 and the Bf-109 E-3. You also do have to worry about aircraft like the Bf-109 F-1, which has a 20 mm cannon in the propeller hub. While it is unlikely, you may also face the Fw-190 A-1. Most German planes will have a significantly better climb rate than you and be able to energy fight you more efficiently. As mentioned earlier, most German planes boast much heavier firepower than you, which renders you at a disadvantage in punching power.
 
 
 
Most Russian planes will also give you a run for your money. Almost all of the Russian planes boast only nose-mounted weaponry, giving them a significant advantage over most allied planes. The most common enemies to worry about are any plane with the prefix "Yak." Perhaps the most common cause of US teams being defeated by the Russians, is the fact that they head on an IL-2. '''Never''' under any circumstance head on an IL-2.
 
 
 
====Counter-tactics====
 
<!--What to expect, if it would be in command of the enemy and how to counter it. (i.e. They will most likely BnZ, etc.)-->
 
As mentioned earlier, the H-81A-2 has nose-mounted .50 cals, which can make short work of almost any fighter at battle rating 2.3. The aircraft also has a tighter turning time than the P-40E, which can give a H-81A-2 pilot a small advantage. If a H-81A-2 finds its way onto your tail, try to make the pilot over-shoot or bleed energy. The cockpit, while having more protection than an open top and a bubble canopy, is still a fairly vulnerable spot, so pilot snipes aren't uncommon.
 
 
 
Heads up for German and Russian pilots! While aircraft like the Bf-110, LaGG-3 and the Yaks have nose-mounted weaponry, an experienced H-81A-2 player can still make you pay dearly in a head-on. If you find yourself in a head on with a H-81A-2, fire a short burst, then hit the deck to avoid being hit by return fire. This is especially true with the Russians due to their wooden air frame.

Comparison with analogues

The Ho-103 is one of the weakest aircraft HMGs in War Thunder.

Projectile mass (and thus explosive/incendiary payload) is lower than both the American .50 BMG and the German 13x64B cartridges. Muzzle velocity is slightly higher than the German MG 131, but over 100 m/s lower than the American M2. The low mass and low velocity reduce the effective range of the weapon and increase the necessary angle for bullet drop compensation.

The Ho-103 is nose-mounted and synchronized in many Japanese aircraft, cutting the fire rate in half. The result is a machine gun that fires a weak cartridge with high drop and a short effective range at as little as half the fire rate of its contemporaries.

Usage in battles

  • Due to the low velocity, it is often impractical to use the Ho-103 at anything other than close range
  • The low damage output and (frequently) low fire rate means a sustained burst is generally required to disable a target.
  • The typically low ammunition count of Japanese aircraft using the Ho-103 means that ammunition must be conserved judiciously.
  • The Default and Tracer belts should not be used if possible. The lack of explosive incendiary bullets greatly reduces damage dealt.

Pros and cons

Pros:

  • The weapon itself is fairly light.
  • The fired 12.7 mm rounds consistently do more damage than 7.7 mm.
  • The unsynchronized rate of fire is high.

Cons:

  • Low muzzle velocity.
  • The available shells have comparatively weak payloads.
  • Low synchronized fire rate.

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
