Submarines have been around for quite some time, in fact one of the earliest records of a submarine design including buoyancy control system, was in 1578 by William Bourne, however, research submarines have been a relatively new addition to the idea of underwater submersibles.
The first submarine built in modern recorded times was in 1605 by Magnus Pegelius. Although the idea of a submarine has been around for half a millennia it has been only recent years that the Sub design was pursued. In fact it wasn’t until the 19th century that the Submarine design started to gain momentum.
In 1959, Frenchman Jaques Cousteau one of the first research submarines, aptly named the “Diving Saucer” due to its shape was launched from the his Ship the “Calypso” and was used to explore the shipwreck HMHS Britannic.
In the same year the Italian research submarine “The Trieste” departed San Diego on a voyage that still sits in the record books as the deepest ever dive by a manned submarine at a point called Deep Challenger. Deep Challenger is the deepest part of the earths Ocean located in the southern part of the Marianas Trench.
Although commonly known as submarines these types of underwater crafts or known as submersibles. This is due to the fact a submarine is completely autonomous where a submersible is generally supported by a ship.
Since the design of this alien looking diving saucer, and the deep diving Trieste research submarines have advanced significantly in their ability to withstand immense pressures, have greater maneuverability, agility and maneuverability, record massive amounts of data and produce amazing high definition footage.
As with most technological advancements, research submarines are no different, a continuing game of what competitor can out-do the other.
