The writing about "USS Turtle" the first submarine of the US Navy from the Independence War 1776.

The first submarine of the U.S Navy was egg-shaped "USS Turtle", what made the first submarine attack in the history against British ships in New York harbor. This submarine had the capacity to slip in the harbor, and then put the explosives under the ships hull, but those attacks failed because the explosives were wet.

As a technical solution "Turtle" was quite interesting, and it had very much capacity if it were covered by glassed clay or rubber layer, what would give it the capacity for deep submerge, and of course the user of that submarine must have gas mask against the carbon dioxide. The propels could use by a similar plate, what was used in "singer" pedal sewing machine. If that singer-system would be used in that submarine, the man who controlled it would not get so tired, and this person could move this submarine faster.

We must remember that this kind of small submarines, what is used by muscle power could be dangerous even today because the modern explosives like C-4 are capacity to explode even they were wet. Everybody can try to build this kind of vehicle, and the problem is the sealing of the windows and other changes.

For the personal safety, the user of this submarine need only seal the hull very sharply. And then the user of this submarine has modern scuba-equipment, this submarine would be lethal. In this scenario, the submarine's mission is to give cover to the water pressure, and the man, who controls that unit can use recycling pressure air system, what will recycle the air by using active carbon filters, and that kind of thing might slip in any harbor.

The shape of the egg is very good against the pressure, and in some scenarios, the modern nuclear depth charges will be made in the shape of egg or ball. The implosion mechanism would be covered by this shape, and it will give it the capacity to submerge quite deep, and destroy any submarine, what is lurking in there.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments.

The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
