What is dimension of the submarine?

The dimensions of a submarine can vary widely depending on its type and purpose. For example, a typical military attack submarine like the U.S. Navy's Virginia-class is about 377 feet long and approximately 34 feet wide, with a displacement of around 7,800 tons when submerged. In contrast, smaller research submarines may be significantly shorter and lighter. Overall, submarines are designed to be streamlined for underwater navigation and can range from small manned submersibles to large military vessels.
