The emergence of missiles in Russia noted by the chroniclers in the Pskov chronicle of the XV century In 1680 in Moscow organized a special “school” for the production of lighting and flares. In 1717, the Russian army was adopted grenade dynamites lighting signal, rises to a height of 500 fathoms (1 fathom = 2.13 m). In the eighteenth century in India, English General Convex designed their own patterns of missiles and achieved flight range of the missiles up to 3 km away. the Missiles of the Convex was used in the war with Napoleon 1812 – 1814 In particular, these missiles English fleet bombarded Copenhagen, “convincing” Danes join the French fleet, gathering forces for the invasion of England.THE CREATORS OF “FIRE ARROWS”

In early 1939, at the meetings of the military and industrial leadership of the Soviet Union repeatedly raised the issue of creating new types of fighters and about the increasing power of the aviation industry in case of war could not cope with the necessary volumes of deliveries of combat aircraft. The impetus for this was the analysis of air fighting in Spain, where it became apparent technological backwardness of Soviet fighters I-15 and I-16 from the new enemy aircraft, particularly from the German BF-109.
From the very beginning of the history of water transport designers and engineers sought to give the courts the ability to move with the greatest speed. It was necessary to reduce the hydrodynamic resistance of the hull. The race for “Ghost of speed” led to the most radical solution -to completely eliminate contact of the hull with the water surface! This was made possible thanks to the creation of wig – the courts break the wings.
As we have seen, the “underwater thing” in France during the time of Napoleon special did not develop, despite quite a rich flow of suggestions, starting with Robert Fulton. However, ironically, the submarine had to rescue the deposed Emperor from captivity on the island of St. Helena. The twists and turns of a real trace in the history of shipbuilding have left, but are curious as illustrations of the rapid “underwater currents”, which was accompanied by the development of new technology.
Firm “Gather of waggonfabrik” (better known as just “goth”) at the end of the 1930s, released the first batch of ten-seat amphibious gliders DFS 230 was developed in the German Institute for the development of gliding (Deutches Forschungsanstalt für Segelflug, abbreviated DFS) under the direction of G. Jacobs. At the plant “goth” production of the DFS 230 was engaged in engineer A. Kalkert. Taking a series of DFS 230, Kalkert thought on creating a larger glider capable of carrying 20 soldiers with full equipment, and oversized cargo. He had to have a large hatch with size approximately equal to the cross section of the fuselage, and upper wing. The cargo hatch designer decided to make a hinged tail of the fuselage, as the nose of the glider could get damaged when landing (which often happens). This entailed the use of twin-boom tail. This layout was previously known, but was first applied to aircraft of this size.
A large part of the surface of the Earth is covered with water. Since ancient times people preferred to live near rivers, lakes, seas and oceans, learning the techniques of crossing water spaces. It was so even in the ancient world, as the formation of the merchant fleet, there are warships escorting the cargo ships.
Combat reconnaissance patrol vehicle BRDM-2. This year marks half a century of adopting the Soviet Army armored reconnaissance-patrol car BRDM-2, continues his military service today. The design of the BRDM-2 was started in 1959 in SLE engineering and experimental Department of the Gorky automobile plant. At this time there already have considerable experience in the creation of armored vehicles of light class: in the early 1950s was designed BTR-40 (factory index GAS-40), and in a few years – armored reconnaissance and patrol vehicle BRDM (factory index GAS-40П, letter “P” stands for floating). The latter, in accordance with the new operational-tactical views on the ways of warfare, could without training to overcome water obstacles and trenches, ditches and trenches on the battlefield. This contributed to a sealed wodospadu reinforces the case and additional pull-out rollers.
“…Earth was a dull rumble, and on the outskirts of the village of Sitno seemed huge armored vehicles unusual bright yellow color. Glistening tongues of shots, they were slowly sliding in our direction. “Rheinmetall”! — I guessed, remembering the silhouettes of German tanks in the album school. — Heavy gun seventy-five, eight hundred straight shot, the armor is forty…” Yes, the frontal armor of such a tank 45 mm gun of our BT is unlikely to take… But there was nowhere to retreat.
After the Japanese turned their 155-mm pseudologia “Mogami” in a normal heavy cruiser, armed with jasminewebcam, the fleet of the Country of the rising sun was in a curious position. Japan was the only major Maritime powers, not having to the beginning of the Second world war, no one modern light cruiser. All units of this class belonged to the older types 20 years; no restructuring and modernization could not make them full-fledged rivals to modern British, French and especially American ships of the same class.
The winter of 1940 was severe and snowy. So when in late February the first two experienced thirty went to the unprecedented thousands of kilometres of mileage on the route Kharkiv — Moscow, he became perhaps the most rigorous and impartial examiner and for new machines and their designers and producers. By the way, one of the tanks was himself Mikhail I. Koshkin, head of while the Department designed the T-34.
