What is the current standard for anchor chains in the Navy during wartime?

The standard for anchor chains in the Navy during wartime is die-lock chain. This type of chain is designed with a specific interlocking system that improves strength and minimizes the chance of accidental disengagement of the links, making it particularly effective under the dynamic conditions often encountered in wartime scenarios. Die-lock chains can better withstand high loads and harsh environmental conditions, which is critical for ensuring the reliability of anchoring operations when the stakes are high.

Other materials, such as wrought iron, BBB close link steel, and cast steel, do not possess the same combination of flexibility and strength required for modern naval operations. While they may have been used in the past, advancements in metallurgy have led to the preference for die-lock chain, particularly for military applications where performance and safety are crucial.
