What only nicknames and designations were attributed to it (sometimes intentionally) that, until recently, a top-secret aircraft, “Lame Goblin”, “Ghost”, “Ghost”, “Rocket bat”, “Blue Mary”, “Nighthawk”, “Aurora”, CSIWRS, COSIRS, CSIRS, F-19, RF-19, A-19, AR-19, F-25. Now it is know as the F-117A “night hawk” (“Nighthawk”)… the History of the airplane has its roots in the beginning of 70-ies. Development of technological methods for creation of stealth aircraft / vehicles began in the United States, likely in the mid 60-ies. The next step in this direction was the attempt of building with application of the developed technology aircraft low level giveaways, i.e. demonstrators.

Drafting of a new heavy tank, much superior to commercially produced is-2 on armor protection began in accordance with the decree of GKO No. 5583 on 8 April 1944 and had its prehistory. A group of researchers of the Military Academy of mechanization and motorization in the name of Stalin, led by engineer-Colonel A. Zavialov studied in the field of tank battles the battle of Kursk, the nature of the damage caused by the shells hitting tanks. It turned out that not all parts of the tower and was amazed the same: more suffering frontal part, while the number of hits in the tower was the greatest. The result of these studies and was the project of a new tank.
For more than six months of heavy fighting on land, at sea and in the air. The Soviet warriors and the creators of the weapons – designers of tanks, guns, ships and planes – accumulated front-line experience. Started in 1942…
In recent years, publication in the journal “modelist-Konstruktor” of the Amateur autocostruzione Willy-nilly suggests that homebrew almost refused to create a full character, complexity and depth of cars in favor of predominantly simplified in design “midget” two stroke engines. We are glad to inform that this is not so. Proof of that is created by our reader V. Revoluta from Stavropol NRA beautiful design passenger car “Natasha”.
In the postwar period the plans for the organization of our armored forces military experts associated primarily with the latest heavy tank is-3. Commercially the tank was produced at the Chelyabinsk Kirov plant in 1945-1946 very fast pace. So, in the summer 1945 issue was, for example, 250 items per month. There were manufactured 2305 machines.
In the nineteenth century, the United States became a real “worker” in the field of underwater shipbuilding. To a large extent this contributed to the Civil war in which both sides actively tried to use all conceivable technical tricks. However, the “underwater Express” has typed a full speed not immediately. After the second (and, as it turned out, last) war against England came decades latent fermentation of thoughts, not often manifested in the final product. Only in 1851, a curious enthusiast, Lodner Phillips issued the first “product”, so to speak, of the new bottling. 26-year-old inventor came from a quite land of Indiana, had no formal education, knew little of the experience of his predecessors, and his main profession was… Shoe business. And available funds had virtually no.
In 1957 the Soviet Union began to develop missiles for army vehicles. In the Kolomna Design office of mechanical engineering B. Shavyrina studied the possibility of equipping tanks missiles as additional weapons to the placement of missile launchers on the tower. In Bureau of the Chelyabinsk tractor plant, headed by P. Isakov, the Leningrad Kirov factory, headed by Zh. Kotin, “Uralvagonzavod” by L. Kartseva was carried out design work and testing of rocket tanks.
It would seem that after Robert Fulton managed to create an almost working submarine, the diving business had to go forward with good speed. However, the main engine of progress in this area was the war, and after the bloodiest of the Napoleonic era in Europe and America came a lull. Of the immediate followers of Fulton can be mentioned is that the brothers Kössen, who had just “to the table” and built in 1810 in Le Havre an obvious rip-off of the first “Nautilus”. (Actually, the brothers did not hide a “source of inspiration”, even naming his creation “the Submarine Nautilus”).
