The Mark V Diving Helmet was an iconic piece of equipment used by the US Navy from 1916 through the early 1980s. Renowned for its distinctive design and robust construction, the Mark V became a symbol of deep-sea diving during its era. The helmet was crafted from spun copper and brass, providing both durability and protection for divers working in harsh underwater conditions. It featured a large, front-facing viewport for visibility and several smaller side and top ports for additional light and communication. The Mark V helmet was used in a variety of underwater operations, including salvage missions, underwater construction, and naval warfare. Its legacy continues to influence modern diving equipment design, making it a revered artifact in the history of maritime exploration.
