They conatined brasAns 2 - The biggest single difference in modern day submarines is the nuclear propulsion system. This allows much greater length of cruises and far more versatility in general.
We have more technology.
The early SS and the newer GATO Class diesel submarines.
The answer is ASDIC
Only a few British submarines were involved landing advance recconnaisance soldiers during the early days of June 1944.
Today's atomic powered subs can stay under water forever. They only surface to re-supply for the men (food and hygiene materials). Living on a modern atomic sub is like living in a small room. Prior to nuclear subs, the diesel powered vessels were nick-named PIG BOATS because it was like living under the hood of your car, sleeping/eating/living with the car's engine.
Many early submarines were failures. However, as many countries in the world now own and even build submarines, we could reasonably call them a success.
The transition between Middle English and Modern English took place slowly and at different times in different places. Chaucer (1380) is clearly Middle English, and Shakespeare (ca. 1600) is clearly Early Modern. Malory's Morte D'Arthur (1485 or so) is probably the earliest major work which is Early Modern English. The distinction between Early Modern English and later kinds of Modern English is harder to draw, because Early Modern English is essentially Modern English with occasional aspects of older English. These older aspects only gradually became less common in English and some of them have still not disappeared. (Consider, for example, Darth Vader's line "What is thy bidding, my master?") An end date for Early Modern of the end of the seventeenth century is somewhat arbitrary but as good as any other.
Nothing - the word "Boat" has been applied to Submarines since they were first used in the Revolutionary War, and the term has stuck with them since then. A "boat" in Naval parlance is any vessel that is launched from another ship or tender, such as a launch, whaleboat, etc. Early submarines required a support vessel (tender) to launch and recover them;though modern submarines don't require such, they do need support from tenders for supplies and repairs. Submariners always refer to their ships as boats, and not ships. The reason for this is that to submariners there are only 2 kinds of ships; Submarines, and Targets.
Many of the early submarines ran on diesel engines. These were used when on the surface for propulsion and power, as well as charging the batteries. When they submerged, they ran on electric power from the batteries.
Early modern France was created in 1492.
