The size of a submarine can vary significantly depending on its type and purpose. For example, a typical military submarine, like a U.S. Navy Virginia-class submarine, is about 377 feet (115 meters) long and can displace over 7,800 tons when submerged. In contrast, smaller research submarines may be around 20-30 feet long, while larger ballistic missile submarines can exceed 500 feet (152 meters). Overall, submarines range from small, personal submersibles to large military vessels.
They are about 20ft in length.
The first submarine was about 46 feet in length and assembled in Barcelona, Spain. The first successful launch of this submarine was in 1864 and held a crew of two people.
Submarine ballast tanks and their number depend entirely on the type of boat and its submerged displacement capacity. In general though, they're pretty big, on average about 6000 square feet or more.
