The 76 mm/62 OTO-Melara Compact is the Italian equivalent of the [[76 mm/60 AK-176M (76 mm)|AK-176M]]. It has a fast aiming speed both vertically and horizontally, comparable to the AK-176M. This particular gun has one of the best tradeoff in accuracy, stopping power and range. While is not the first 76mm naval deck gun seen in game, it is by far one of the best, if not the best, multi-purpose weapon system available for both naval combat and ground combat. The compact version of the OTO Melara 76/62 has a smaller carousel to be fitted with more ease on many platforms.

The OTO Melara 76/62 has access to various rounds that are specific for this weapon system: the 76/62 SAPOM, 76/62 HE-MOM and 76/62 APFSDS. However, this last one is only available in the [[OTOMATIC]] and is not seen in any naval vehicle. The proximity fuze on the HE-MOM will only trigger when on proximity with enemy airfract, and as such, it is recommended to use this ammunition as primary ammunition when in naval combat.

The OTOMATIC has access to the 76/62 SAPOM, 76/62 HE-MOM and 76/62 APFSDS rounds. While they carry identical names, these shells are different from their naval counterparts and the APFSDS shell is exclusive to the OTOMATIC.
−
''SAPOM:''
 
  
−
The Semi Armor-Piercing High Explosive Incendiary rounds has multipurpose capabilities with a little bit of everything. It has a nice tradeoff between anti-air, anti-tank and anti-ship capabilities due to the explosive mass and armor penetration. However, the SAPOM is not really suggested for anything rather than anti-armor roles as the HE-VT* is more than capable of dealing with enemy threats. It should be notted most of the targets faced can be killed from the sides if shot between the road wheels in the lower half of the chassis (in case for NATO tanks), engine deck (will only cause fire and damage to transmission), Gunner's Primary Sight (in case of M1 Abrams and XM-1's). When it comes to dealing with Russian targets (the most generally armored MBT's in the game), SAPOM should be fire almost at the ground hitting the lowest part of the chassis. It is recommended to destroy their tracks and barrels in order to let friendly units take them out for this reason. SAPOM is capable of destroying all lightly armored targets seen at the battle-rating (IFV's, SPAA's, etc).
+
'''Naval vessels'''
  
−
It is particularly useful when facing medium armored destroyers and little armored cruisers. While it may not cause as much damage as any other naval wapon system, the high ROF can cripple enemy vessels in seconds. While it may not destroy them, it will surely cause significant damage, specially if the rounds are fired at the weapon turrets.

The High Explosive Variable Time fuze proximity shell has a full anti-air role with use for lightly armored targets, specially naval targets. Thanks to the high caliber, the HE is able to carry a proximity fuze with a lethal explosive mass, making it capable of destroying all aerial threats with one or two hits. Trigger discipline is recommended as, due to the fast fire rate, the whole ammunition reserve can be consumed really fast. Thanks to being a big shell, most enemy helis and aircraft will not redirect course when being fired at until it's too late compared to the continious fire smaller caliber SPAA have (25mm, 30mm, 35mm, 40mm, etc). They do not trigger Missile Alert Warning, making them the ultimate helicopter killer. However, the muzzle velocity of the HE-VT* is slower than most high caliber anti-aircraft systems, making it harder to hit targets at long ranges.

The dart ammunition hs '''only available in OTOMATIC''', it has a full anti-tank role though it can be used for anti-air roles, however it is not recommended. It has decent penetration and stopping power as a dart and is more than capable with dealing enemy tanks. It is able to destroy enemy targets in one hit if it's a well placed shot. Ammunition should be targeted with the APFSDS as the low ammount of ammunition carrying can make it run out of APFSDS before destroying the enemy. Trapshots are suggested (driver's port, cupola, mantlets, etc).
+
The gun features a rare combination that gives it an exceptionally high damage output - very large explosive filler and an extremely high rate of fire for the caliber, ejecting 1 shell every 0.7 seconds. It's further improved by excellent targeting speed and one of the best muzzle velocities.

Both systems are extremely similar except that the OTO Melara has access to semi-armour-piercing ammunition. It typically carries less ammunition than the AK-176M (though the specific amount depends on a ship - Italian and British vessels carry only 115 shells while German carry 400 shells per gun) but can put more rounds in the air due to the higher rate of fire.

When talking about just the HE and HE-VT shells, the OTO Melara 76/62 has a much higher explosive payload (nearly double) but has a lower muzzle velocity (925 m/s vs 980 m/s). Both systems do the same purpose with different approaches, one uses a faster round with less payload and the other vice versa.

The OTO Melara 76/62 is a quick firing multi-purpose gun capable of destroying surface targets and annihilating airborne targets. The gun has two different engagement modes which will be described further:

 +
The 76 mm excels in outputting a large amount of explosives on target in bursts. For the caliber, it has an exceptional damage potential, far above foreign competitors, in the right hands making it a perfect weapon for an ambush. That said, it's in an uncomfortable spot, where the caliber is too large against some of the coastal vessels, yet too small to easily ammo-rack enemy destroyers. That said, it's one of, if not the best anti-air gun, featuring HE-VT shells, a great rate of fire for the caliber, targeting speed, and very good vertical guidance, making it easy to take down enemy airplanes (note that Bussard and LÉ Orla uniquely have secondary armaments, allowing you to rely on AI to take the enemy planes down at a distance).
  
−
==== Long Range Engagements: ====
+
=== Pros and cons ===
−
The low dispersion and high muzzle velocity, meaning it has a high accuracy, makes it very good at long range engagements. However, sometimes the player may go "happy trigger" and fire salvo after salvo of countless rounds to engage a target. That is exactly what you should not do in long range engagements. Instead, fire in salvos of 2-3 rounds to ensure accuracy and reduce ammo waste. Make sure to not engage with targets past 10 km. Past that range the gun loses tremendous accuracy, it can reach ranges up to 15 km but the optimal is smaller than 10 km.
+
<!-- ''Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.'' -->

'''Airborne engagements:'''
+
'''Pros:'''
 +
* Exceptional damage output
 +
* High rate of fire
 +
* Very large explosive filler in the HE and HE-VT shells
 +
* Excellent targetting speed
 +
* Good muzzle velocity
  
−
It is pretty straight forward, detect-designate-track-engage. However, again try to avoid trigger happiness. Reduce ammo waste by firing 2-35 round salvos. Hitting airborne targets is harder than surface targets despite the use of proximity fuze. Make sure you leave a firing gap between your first and second salvo. Example: first salvo of 3 rounds, wait for them to reach the target, confirm if there has been any hit or manoeuvring instead, correct aiming if needed, second salvo of 4 rounds, etc etc etc. The use of tracking radar makes plane hunting easier, but it should be noted that sometimes tracking radars tend to display a somewhat awkward lead indicator. Use it as a guide but do not solely rely on it.
+
'''Cons:'''
 +
* Either very limited ammunition (for just 80 seconds of continuous fire) or no access to the SAP shells (depending on the ship)
 +
* SAP shells are prone to over-penetration against coastal vessels
 +
* Being a weapon used only on the coastal vessels, it has no access to the shell chase camera
  
−
==== Close Range Engagements: ====
+
== History ==
−
The story somewhat changes in this matter. The "happy trigger" here is not as backfiring as when in long range, instead, it is actually needed and required in some cases, specially when it comes to point blank defense or inside ranges closer than 1.5 km. Salvos here are not exactly needed or there is a recommended salvo count. Fire at discretion. Be aware! If the gun keeps firing for long, it will overheat!

One crucial thing to note is the ammunition count in first stage ammo rack. While this is not a big of a deal when in naval vehicles, it sure is while playing the OTOMATIC. You will take more time to refill the first stage ammo rack than to fire the entirety of your ammunition!
 
−
 
 
−
'''Airborne engagements:'''
 
−
 
 
−
This is easier but trickier than long range, this is why: when it comes to close range air defense (0-5 km), there is only so much time you have to engage the target before it is too late, make sure you engage them ASAP. The main downside of close range engagements is the fact you have a much smaller correction window as the aircraft is able to fly above you, forcing you to elevate the gun completely and/or rotating to be able to keep him on sights, something that tends to create issues and reduced combat performance as you have your gun out of combat. While it does not take much time to aim once again, it sometimes can be the difference between life and death.
 
−
 
 
−
One of the main advantages of using the HE-MOM round is the fact you can destroy air launched munitions such as missiles and bombs. However, this requires '''a lot''' of practice .

The OTO-Melara Compact is an Italian naval weapon designed to serve as a multi-role gun that defends smaller naval vessels as anti-missile point defense, anti-ship and anti-surface guns. The 76/62 was was developed in the 1960s based on the earlier [[wikipedia:76mm/L62 Allargato|76mm/62 Allargato]] guns. Design work on the gun begun in 1964, with initial prototype being built in 1968. Testing campaign continued for about a year, after which, in 1969, a serial production of the gun has begun. First units were delivered to the ''Marina Militare'' in 1973, and the gun quickly became an export success with the adoption by the US Navy to the USS ''Oliver Hazard Perry'' guided-missile frigates
  
−
'''Cons:'''
+
In total 60 other navies around the world used the 76. Some of the most notable examples among them included German [[Albatros|''Albatros''-class fast attack craft]], the ''Gepard''-class fast attack craft, the ''Braunschweig''-class corvette along with the frigates of the ''Brandenberg, Bremen, Sachsen,'' classes. The Irish Navy uses the guns from former Royal Navy ''Peacock''-class corvettes such as the [[LÉ Orla]], and their locally designed patrol vessels ''Róisín''-class and ''Samuel Beckett''-class.

The Italian Navy uses the OTO-Melara Compact model on the ''Audace-class'' Destroyer, ''Minerva-''class corvette, the Franco-Italian ''Horizon-''class frigate, the ''San Giorgio-''class and the [[Sparviero|''Sparviero''-class patrol boats]].

The Italian Army also made two plans to turn this naval cannon into a anti-aircraft weapon. The first was the [[OF-40 (Family)|OF-40-based]] [[OTOMATIC]], which was never adopted due to budget cuts, and the second was the Draco, a [[Centauro (Family)|Centauro-based]] design, that only exists as a mock-up.

Naval vessels

General info

The 76 mm/62 OTO-Melara Compact is the Italian equivalent of the AK-176M. It has a fast aiming speed both vertically and horizontally, comparable to the AK-176M. This particular gun has one of the best balances of accuracy, stopping power, and range. While it is not the first 76 mm naval deck gun seen in game, it is by far one of the best multi-purpose weapon systems available for both naval and ground combat. The compact version of the OTO Melara 76/62 has a smaller carousel to be fitted with more ease on many platforms.

Available ammunition

The Albatros and the Bussard have only access to the DM-251 and DM-261 rounds, while HMS Peacock, LÉ Orla and the Sparviero have access to the 76/62 HE-MOM, the 76/62 SAPOM, and the 76/62 HE-VT MOM shells.

The OTOMATIC has access to the 76/62 SAPOM, 76/62 HE-MOM and 76/62 APFSDS rounds. While they carry identical names, these shells are different from their naval counterparts and the APFSDS shell is exclusive to the OTOMATIC.

Compared to AK-176M

Both systems are extremely similar except that the OTO Melara has access to semi-armour-piercing ammunition. It typically carries less ammunition than the AK-176M (though the specific amount depends on a ship - Italian and British vessels carry only 115 shells while German carry 400 shells per gun) but can put more rounds in the air due to the higher rate of fire.

When talking about just the HE and HE-VT shells, the OTO Melara 76/62 has a much higher explosive payload (nearly double) but has a lower muzzle velocity (925 m/s vs 980 m/s). Both systems do the same purpose with different approaches, one uses a faster round with less payload and the other vice versa.

Usage in battles

The 76 mm excels in outputting a large amount of explosives on target in bursts. For the caliber, it has an exceptional damage potential, far above foreign competitors, in the right hands making it a perfect weapon for an ambush. That said, it's in an uncomfortable spot, where the caliber is too large against some of the coastal vessels, yet too small to easily ammo-rack enemy destroyers. That said, it's one of, if not the best anti-air gun, featuring HE-VT shells, a great rate of fire for the caliber, targeting speed, and very good vertical guidance, making it easy to take down enemy airplanes (note that Bussard and LÉ Orla uniquely have secondary armaments, allowing you to rely on AI to take the enemy planes down at a distance).

Pros and cons

Pros:

  • Exceptional damage output
  • High rate of fire
  • Very large explosive filler in the HE and HE-VT shells
  • Excellent targetting speed
  • Good muzzle velocity

Cons:

  • Either very limited ammunition (for just 80 seconds of continuous fire) or no access to the SAP shells (depending on the ship)
  • SAP shells are prone to over-penetration against coastal vessels
  • Being a weapon used only on the coastal vessels, it has no access to the shell chase camera

History

The OTO-Melara Compact is an Italian naval weapon designed to serve as a multi-role gun that defends smaller naval vessels as anti-missile point defense, anti-ship and anti-surface guns. The 76/62 was was developed in the 1960s based on the earlier 76mm/62 Allargato guns. Design work on the gun begun in 1964, with initial prototype being built in 1968. Testing campaign continued for about a year, after which, in 1969, a serial production of the gun has begun. First units were delivered to the Marina Militare in 1973, and the gun quickly became an export success with the adoption by the US Navy to the USS Oliver Hazard Perry guided-missile frigates

In total 60 other navies around the world used the 76. Some of the most notable examples among them included German Albatros-class fast attack craft, the Gepard-class fast attack craft, the Braunschweig-class corvette along with the frigates of the Brandenberg, Bremen, Sachsen, classes. The Irish Navy uses the guns from former Royal Navy Peacock-class corvettes such as the LÉ Orla, and their locally designed patrol vessels Róisín-class and Samuel Beckett-class.

The Italian Navy uses the OTO-Melara Compact model on the Audace-class Destroyer, Minerva-class corvette, the Franco-Italian Horizon-class frigate, the San Giorgio-class and the Sparviero-class patrol boats.

The Italian Army also made two plans to turn this naval cannon into a anti-aircraft weapon. The first was the OF-40-based OTOMATIC, which was never adopted due to budget cuts, and the second was the Draco, a Centauro-based design, that only exists as a mock-up.
