Submarine Deployment Storage: When and How are Torpedo Tubes Utilized?

When a submarine embarks on a deployment, the torpedo tubes serve a multifunctional purpose, often acting as both launch vehicles and storage units. Contrary to their primary role in launching torpedoes, these tubes can house various equipment, supplies, and materials during certain missions and operational scenarios. This article explores the specifics of when and why torpedo tubes can be used for storage, along with interesting stories and anecdotes from submarine crews.

The Dual Purpose of Torpedo Tubes

While the primary function of torpedo tubes is to launch torpedoes, they can also serve as storage units for additional equipment and supplies. This is particularly relevant when the submarines are not fully loaded with torpedoes for the specific mission. Such storage needs can range from essential equipment and sonic shields to food and beverages, all secured to prevent shifting or damage during transit.

Case Study: Eggs and Submarine Storage

A notable example involves the storage of eggs. During a deployed mission, a submarine's torpedo tubes can accommodate supplies like eggs, ensuring they remain fresh and secure. These tubes often act as makeshift insulated fridges due to the surrounding cold water, making them ideal for perishable items. This was confirmed by an operator on a fast-attack submarine, who noted the utility of the torpedo tubes for storing a variety of goods, including eggs, during long deployments.

Operational Flexibility and National Defense

The use of torpedo tubes for storage can vary based on the submarine's mission, operational requirements, and specific mission necessities. National defense considerations can also play a role, with different signs and labels indicating the status of the torpedo tubes. Examples include "Empty," "War Shot," "Loaded," and even "Booze Loaded."

The poster noted, "The exact use of the torpedo tubes for storage can depend on the submarine's mission, operational requirements, and the specific configuration of the vessel." Such flexibility allows submarines to adapt to changing conditions and operational needs.

Historical and Cultural Anecdotes

A particular case involves German U32 submarines, which have a curious reputation for storing beer in their torpedo tubes. According to a documentary, a crew member was seen stowing beer cases in the tube, a practice noted for its unique cultural aspect.

Practical Considerations

Using torpedo tubes for storage has practical implications for operational security and stealth. As mentioned, it would be counterproductive to use the tubes for storage when weapons are needed, especially during mission-critical phases. However, certain specialized projects might require the storage of non-weapon items, such as food, in the tubes to optimize space and logistics.

For security reasons, it's important to note that the tubes are only used for storage when necessary, and only under strict guidelines. Typically, the tubes are left empty or loaded with weapons until the immediate need arises. This careful management ensures that the submarine remains as stealthy and effective as possible.

A Unique Liberty Permit

One unique incident showcasing the versatility of torpedo tubes occurred during a deployment. The submarine's captain allowed crew members to purchase rum and store it in a locked and secured torpedo tube during a port stop in Frederiksted, St. Croix, in the US Virgin Islands. This practice, known as "Torpedo Tube Rumble," was a special perk for the crew members, adding a touch of culture and tradition to their deployment.

When the submarine returned to its home port, crew members retrieved their drinking allowance from the torpedo tube on their way off the ship. This story emphasizes the adaptability of the submarine's design and the camaraderie among the crew.

Overall, the torpedo tubes of submarines transform from launch vehicles to storage units, showcasing the adaptability of submarine design to meet various operational needs. These diverse uses mark a testament to the ingenuity of naval engineering and the resourcefulness of submarine crews.
