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 trade-off in 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 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.

Available ammunition

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

Comparison with analogues

Compared to AK-176M

Both systems are extremely similar except that the OTO Melara has access to armour-piercing ammunition. It carries less ammunition than the AK-176M (115 vs 152) 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 72/62 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 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:

Long Range Engagements:

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.

Airborne engagements:

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.

Close Range Engagements:

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 .

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

Excellent additions to the article would be video guides, screenshots from the game, and photos.
