General info

Comparison of the 37 mm/54 Breda family, from the left: Mod.32, Mod.38, and finally a single-mount Mod.39.

The gun comes in a two different variants - the one on RN Attilio Regolo having a slightly longer reload time between firing each of the 6-round magazines. Compared to the other guns in the family, it trades an ability to fire at targets directly above the ship for a single gun per mount.

Comparison with analogues

Comparatively speaking, the gun has below-average firepower, with about average guidance speed. The key upside of the gun is its ability to fire on targets at all angles, without leaving any blind spot for enemy dive bombers to exploit.

The Breda 37 mm/54 was a light anti-air gun developed in the early 1930s by the Italian company Breda. It was adopted as the standard light anti-air gun of the Italian army and navy, replacing the British pom-poms. The 37 mm/54 was a gas-operated autocannon that featured a selectable fire rate of 60, 90, or 120 rounds per minute, and was fed by a 6-round sequentially-loaded magazine, which allowed for a high sustained rate of fire. Both single- and dual-mount variants of the gun were built.

The 1939 version of the mount represented a significant advancement for the series, as it addressed a major issue that had been raised by crews - vibrations of the gun. This was achieved by incorporating an equilibrator, which allowed the entire gun to recoil, thus significantly enhancing long-range accuracy. Additionally, a unique collapsible single-gun mount was developed. It featured a mechanism that enabled the entire gun to be lowered below an armored hatch, when the barrel was lifted up 90 degrees. This design feature protected the gun from environmental factors or shrapnel damage when there were no valid targets to engage.

It is noteworthy that the Mod. 1939 was not the last iteration of the gun. A variant known as the Mod. 1941 was designed and developed, but it was never put into production. This variant was a towed single-gun version that was specifically intended for use by the Royal Italian Army. However, it never saw active service as the necessary production capacity was not available.

The standard ammunition used on the Breda 37/54 was contact high-explosive 37 x 232SR with a muzzle velocity of 800 m/s. The gun was capable of engaging targets up to 5,000 m altitude, or against naval targets at a maximum effective range of 4 km.
