The Truth Behind WWII Submarines' Ammunition Storage for Deck Guns

Introduction to WWII Submarines and Deck Guns Ammunition

In popular culture, the portrayal of WWII submarines often includes extensive scenes where the crew meticulously stores and handles ammunition for their deck guns. However, the reality of such operations was quite different and far less dramatic than what is seen in films and television. This article delves into the actual storage methods employed by WWII submarines for their deck guns, dispelling Hollywood mystique and revealing the historical accuracy of these storage practices.

Myth vs. Reality: Ammunition Carrying Capacity

The misconception that WWII submarines carried large stores of ammunition akin to that seen in entertainment media is just that – a myth. Unlike surface ships, which often had expansive internal spaces designed for large caliber guns and extensive ammunition magazines, submarines had to be more efficient with their limited space. The primary weapon on a submarine was the torpedo, and the deck guns served a secondary role, primarily for anti-aircraft defense.

In terms of ammunition, deck guns were generally equipped with smaller caliber weapons, such as 20mm or 40mm anti-aircraft guns. These guns were essential for defending the submarine from potential aerial attacks, but they were not as heavily relied upon as modern anti-aircraft measures suggest. The ammunition for these guns was typically carried in much smaller quantities compared to the vast magazines portrayed in movies and TV shows.

Strategic Ammunition Storage

The actual ammunition storage for the deck guns on WWII submarines was meticulously planned and stored in small, watertight compartments. First, these compartments were located just below the deck guns. This design was crucial for several reasons.

Firstly, the proximity to the guns minimized the risk of misfire and allowed for rapid deployment. In emergency situations, such as when under attack, the crew could quickly and efficiently load the guns as needed. The small size of these compartments also meant that they could be sealed and protected from water ingress, adhering to the strict requirements of naval engineering.

Secondly, these watertight compartments were strategically placed to reduce the risk of flooding. By isolating the ammunition storage, any accidental discharge or damage to the compartments due to combat would not spread to the rest of the submarine. This was a critical safety measure, ensuring the integrity and operability of the vessel in the face of combat.

Operational Procedures and Efficiency

The operational procedures for these small ammunition magazines were designed for efficiency and ease of use. During peacetime operations, the deck guns would not be continuously loaded with ammunition. Instead, they would be maintained and prepared for rapid deployment. During wartime or actual combat scenarios, the crew would have predetermined plans and protocols for quickly accessing and refilling the ammunition magazines.

These procedures were rigorously tested and practiced to ensure that, if needed, the crew could load the guns and engage effectively within seconds. In reality, the deck guns were more often used for anti-submarine warfare or as a show of force, rather than in direct combat.

Conclusion: Hollywood Fictions and Historical Accuracy

In conclusion, the storage and handling of ammunition for deck guns on WWII submarines were not as extensive as popular depictions suggest. The magazines were small, watertight, and strategically placed to maximize efficiency and safety. These practices were part of a larger, more complex system of naval operations that balanced the need for defensive capabilities with the constraints of a cramped, watertight environment. The enduring appeal of the myth may be due to the fact that the reality is simply less dramatic, but it is no less fascinating when understood through the lens of historical accuracy.
