Which of the following is NOT a type of US Navy recompression chamber?

The identification of the single-lock, 150-psig, 300-cubic-foot chamber as not being a type of US Navy recompression chamber is accurate due to the fact that the Navy employs specific types of recompression chambers that have proven effective in treating decompression sickness and conducting emergency procedures.

The double-lock chambers are designed to safely accommodate multiple personnel, allowing for efficient access and treatment without compromising the chamber's integrity. The standard designs used by the Navy typically feature a double-lock configuration, which enhances operational flexibility and safety for diver rescues.

Transportable systems are also an important aspect of the Navy’s capabilities, enabling rapid deployment in varying environments, which aligns well with mission requirements.

The standout here is the single-lock configuration mentioned in the inaccurate option, which does not conform to the established types utilized by the Navy. Understanding these types of chambers helps emphasize their specific roles and operational usage, underscoring the importance of having the right equipment for diverse underwater rescue situations.
