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 thee 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.

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.

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 OTO-Melara was developed in the 1960s based on the earlier 76mm/62 Allargato guns. The design is used in both the US, German, Irish, and Italian navies and 60 other navies around the world. In the US navy, it is used on the Oliver Hazard Perry-class Frigates and Pegasus-class Hydrofoils along with the Famous-class cutter and Hamilton-class cutter. The German Kriegsmarine (German Navy) uses the gun on the 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.
