The emergence of nuclear submarines dramatically changed the balance of forces at sea, not only between countries but also between classes of ships. Indeed, hunters submarines could easily reach speeds sufficient to prosecute his opponent in a submerged position. However, nuclear reactors combined with a new hull shapes were allowed to reach 30 knots and more, available to only the destroyers.

Lack of range of sonar allowed the submarines in time to escape a dangerous situation. However, as always in the history of arms, and they were equally unpleasant opponent. They became anti-submarine helicopter, which had a huge advantage in speed and the view from the height, especially when using the sonar reentry, which in this case does not prevent the noise of the screws.
THE SECOND COMING OF THE “HYBRIDS”
In the late 70-ies in the press, especially in the journal “modelist-Konstruktor”, wrote a lot about velomobiles. Was presented designs of various authors. Some argued that a new form of transport, which in the future will press not only a bike but a car. However, nothing happened. Why? A simple answer to this question is difficult. Will only Express some thoughts.
