What is the beam measurement of an Ohio-class SSBN?

The Ohio-class SSBN (Ship Submersible Ballistic Nuclear) is known for its significant size and capacity as a ballistic missile submarine. The beam measurement, which refers to the width of the vessel at its widest point, for these submarines is 42 feet. This measurement is critical for understanding the ship's handling and stability while submerged and on the surface.

A wider beam allows for increased buoyancy and stability, which is essential for a submarine designed to carry ballistic missile systems and operate in various conditions. The Ohio-class submarines, being among the largest military submarines in the world, utilize this beam effectively to accommodate their hull design and internal systems, including missile tubes and crew spaces. Other options provided do not reflect the specifications of the Ohio-class, thus reinforcing that 42 feet is the accurate beam measurement.
