For ease of handling, what material has the Navy switched to for accommodation ladders?

The Navy has switched to aluminum for accommodation ladders primarily due to its lightweight and durable properties. Aluminum provides a significant reduction in weight compared to traditional materials like steel and wood, making it easier for personnel to handle and deploy the ladders. This is particularly important in maritime operations where stability and ease of use are crucial. Additionally, aluminum is resistant to corrosion, which enhances the longevity of the ladders when exposed to the harsh marine environment.

While steel may offer strength, its weight can make handling cumbersome, and wood, although historically used, may not withstand the elements as effectively. Plastic, while lightweight, typically does not provide the structural integrity required for safe accommodation ladders in naval applications. Thus, aluminum stands out as the most suitable choice for these reasons.
