The gun comes in two distinct turret designs, both twin-mount, with the earlier design having enough protection to deflect shells from the 4-inch guns at 5,000 m, while the later design increases that protection up to 5-inch, or 127 mm guns at 5,000 m, which is sufficient to deflect a direct hit into the turret face form nearly every destroyer and most of cruisers in a real combat situations.

The primary distinguishing feature of the shells utilized by the OTO's 152/53 mm is their notably small explosive content. This attribute, in combination with an average rate of fire, results in a comparatively lowest potential damage output per minute when compared to similar munitions. {{Annotation|HE|High-explosive}} shells contain an explosive filler that is smaller in size than many {{Annotation|SAP|Semi-armour-piercing}} shells, yet they lack the penetrating power of the latter. Conversely, the {{Annotation|APHEBC|Armor-piercing high explosive with ballistic cap}} shells, despite having the smallest explosive component of any comparable armor-penetrating munition, has only average penetration, making it an overall subpar performer.

The gun possesses two noteworthy advantages. First, its muzzle velocity is among the highest among peers, which, in combination with an above-average rate of fire, makes it relatively straightforward to engage enemy vessels at a distance.

As the primary armaments on a number of Italian cruisers, these guns are primarily employed in direct naval combat against other vessels. Although high-explosive shells lack the killing potential, they can still be employed to disable critical components, such as main guns or torpedo launchers. However, the key potential of these guns is unlocked with the armor-piercing shells. Despite their relatively modest penetration and explosive charge, these shells can still be effective due to the guns' above-average rate of fire, which makes it easier to destroy [[ammo racks|ammunition storage]] on enemy vessels.

The '''152 mm /53 Model 1926–1929''' were built for the Italian Navy in the years before World War II. These guns were used on all Condottieri-class light cruisers except the Duca degli Abruzzi-class.

152/53 mm O.T.O. Model 1929 was developed for use on the 2nd, 3rd and 4th generations of the [[Condottieri-class]] cruisers. The guns were considered advanced for their time, utilizing electrically powered training, elevation, hoists, and rammers along with the common cradle for the two guns in the turret. This allowed the guns to achieve an low weight and exceptional rate of fire compared to other 152 mm guns of the time.
−
The Model 1926 was designed and manufactured by Ansaldo, while the Model 1929 was manufactured by OTO Melara. Although both models of gun were similar in construction, components from each manufacturer were not fully interchangeable.

The gun mounts had electrically powered training, elevation, hoists, rammers and the guns shared a common cradle. Improvements in ammunition handling meant that the rate of fire for the Model 1929 was nearly twice as fast as the Model 1926. Loading was at +20° for the Model 1926, while the model 1929 could be loaded at any angle up to 45°. These guns suffered from dispersion problems so the original muzzle velocity of 1,000 metres per second (3,300 ft/s) was reduced to 850 metres per second (2,800 ft/s) with AP shells. Shell weight was also reduced from 50 kilograms (110 lb) to 47.5 kilograms (105 lb) in an attempt to resolve these problems, but were only partially successful. The main reason for the dispersion problem was because the guns were mounted too close together on a common cradle, which also complicated loading of the guns.

The majority of the ''Condottieri-classes'' had two superfiring twin-mount turrets forward and aft, except for the ''Duca degli Abruzzi-class'' which had different model guns and had two twin-turrets replaced with two triple-turrets. The Giussano-class carried Model 1926 guns, while the ''Cadorna-class'', ''Montecuccoli-class'' and ''Duca d'Aosta-class'' carried Model 1929 guns. The mountings for the ''Giussano-class'' and ''Cadorna-class'' were found to be too lightly built for the recoil forces created by these guns.

However, the guns faced several issues during service, most notably a significant [[wikipedia:Circular error probable|circular error probable]] attributed to factors such as the low mass of the guns, ejecta from both barrels interfering with each other, and variations in the mass of the shells and propellants used. Various modifications were implemented to reduce these issues, but they were only fully resolved with the introduction of the [[152/55 mm Ansaldo Mod.1934 (152 mm)|152/55 mm]] in 1934.

152/53 mm O.T.O. Mod.1929 turrets number 1 and 2 on the RN Raimondo Montecuccoli

Description

The 152/53 mm O.T.O. Mod.1929 is an Italian naval cannon.

Vehicles equipped with this weapon

General info

The gun comes in two distinct turret designs, both twin-mount, with the earlier design having enough protection to deflect shells from the 4-inch guns at 5,000 m, while the later design increases that protection up to 5-inch, or 127 mm guns at 5,000 m, which is sufficient to deflect a direct hit into the turret face form nearly every destroyer and most of cruisers in a real combat situations.

Comparison with analogues

The primary distinguishing feature of the shells utilized by the OTO's 152/53 mm is their notably small explosive content. This attribute, in combination with an average rate of fire, results in a comparatively lowest potential damage output per minute when compared to similar munitions. HE shells contain an explosive filler that is smaller in size than many SAP shells, yet they lack the penetrating power of the latter. Conversely, the APHEBC shells, despite having the smallest explosive component of any comparable armor-penetrating munition, has only average penetration, making it an overall subpar performer.

The gun possesses two noteworthy advantages. First, its muzzle velocity is among the highest among peers, which, in combination with an above-average rate of fire, makes it relatively straightforward to engage enemy vessels at a distance.

Usage in battles

As the primary armaments on a number of Italian cruisers, these guns are primarily employed in direct naval combat against other vessels. Although high-explosive shells lack the killing potential, they can still be employed to disable critical components, such as main guns or torpedo launchers. However, the key potential of these guns is unlocked with the armor-piercing shells. Despite their relatively modest penetration and explosive charge, these shells can still be effective due to the guns' above-average rate of fire, which makes it easier to destroy ammunition storage on enemy vessels.

Pros and cons

Pros:

  • High muzzle velocity
  • Above-average rate of fire
  • Well-armored turrets

Cons:

  • Very small explosive filler of the HE shells
  • Only an average penetration of the AP shells despite of having an the smallest explosive filler among its peers
  • Lack of HE-VT shells

History

152/53 mm O.T.O. Model 1929 was developed for use on the 2nd, 3rd and 4th generations of the Condottieri-class cruisers. The guns were considered advanced for their time, utilizing electrically powered training, elevation, hoists, and rammers along with the common cradle for the two guns in the turret. This allowed the guns to achieve an low weight and exceptional rate of fire compared to other 152 mm guns of the time.

However, the guns faced several issues during service, most notably a significant circular error probable attributed to factors such as the low mass of the guns, ejecta from both barrels interfering with each other, and variations in the mass of the shells and propellants used. Various modifications were implemented to reduce these issues, but they were only fully resolved with the introduction of the 152/55 mm in 1934.

Guns used following ammunition:

  • 55 kg Armor-Piercing shells fired at 975 m/s up to 28,400 meters at 45°
  • 47.5 kg Armor-Piercing shells fired at 850 m/s up to 22,600 meters - these were introduced to reduce the dispersion of the guns
  • 44.3 kg High-Explosive shells fired at 935 m/s up to 24,600 meters

Currently, the only surviving 152/53 mm O.T.O. Mod. 1929 can be found at the Città della Domenica nature and amusement park near the city of Perugia in central Italy.
