One of the most interesting pages in the history of world tank development was, without doubt, the period of creation towered tanks. He covered almost all of the 1920-ies that is not accidental, because the whole concept of mnogobashenniye schema is a logical continuation of the scheme British tanks during the First world war. English diamond machines were created to break through the defensive positions of enemy infantry, therefore, the location of the main weapons in side sponsons seemed quite obvious. When crossing the defensive lines so it was easier to kill the enemy infantry, entrenched in the trenches. Shots were fired from both sides along the trenches. In the process of transition to tower layout, which was apparent at the final stage of the First world war, the scheme with the placement of the weapons in the sponsons transformed into mnogobashenniye.

The Soviet designers managed to create a fighting self-propelled installation SU-85 with a full booking, able to deal with medium and heavy enemy tanks with high maneuverability and passability. Offices and engine and transmission were the same as the T-34 tank. This allowed us to complete the crew without retraining. Unitary munitions and gave an opportunity to reduce its numbers to four, which made a more concerted actions of the crew in battle.
Sweden was and remains one of the few countries in the world, able to create a world-class aircraft. Combat aircraft of that Scandinavian countries have always been some kind of “twist”, they should not be confused with similar machines from other countries. In a world quite similar to each other planes, but similar to the Swedish fighter, perhaps, could not be found. The explanation, in my opinion, is simple: since its inception in the late 1930-ies the Swedish aviation industry is not copied already built foreign aircraft, designed and built their own samples. And the fact that in a short time the Scandinavian engineers to develop could not (for example, modern jet engines and electronic equipment) purchased abroad, including a license for their production. The result of this competent technical policy was the fact that in the postwar “jet race” Sweden is practically not inferior to the world’s leading aviation powers, and in some cases even ahead of them.
The second of may 1952 from London Heathrow airport and went to the first commercial flight to Johannesburg, the world’s first passenger jet airliner “Comet” created by the British firm “De Hevilend”. Subsequent accidents and disasters that accompanied its operation, did not stop the desire of the world’s leading aviation powers to progress and the creation of new reactive machines.
Battles in Normandy in summer 1944 was discouraged by the command of tank units of the allies, including the us. The fact that it is hoped for their means of combating tanks of the Wehrmacht: anti-tank guns, self-propelled artillery installations, including on the American M10. M10 Gun Motor Carriage is self-propelled artillery, which had the informal name of Wolverine (“Wolverine” – “Wolverine”), was the most numerous tank destroyer in U.S. army during world war II. She belonged to the class of fighters and tanks had to destroy on the battlefield armored vehicles, while their own tanks was to support infantry in battle – such was the doctrine of military command of the U.S. army.
During the cold war, the power of States determined by the number of nuclear warheads in their arsenals, but only half a century before — the number of battleships-dreadnoughts. But the rating of Latin American countries in the late XIX — early XX century was measured by the presence of cruisers. However, this was not surprising. Primitive land communications and the practical absence of the railroads virtually the entire turnover of these countries was carried out on the water — after all, significant cities and towns of Latin America are on the coast or on the banks of large rivers.
In 1933, the designers of the American company “Starman” designed the training aircraft, with a motor 215 l,p, called the “model 70”. It was an all-metal biplane with fabric covering, which had fixed landing gear with cantilever main legs and tailwheel. After successful prototype tests launched it into production.
The story of midget submarines began with the artisanal submarines, which can now perform almost any large engineering company – would the money from the customer. But in our time and customers a lot of money, and we are talking primarily about the smugglers and the traffickers. The one who followed world news, noted that in recent years has repeatedly documented cases of the use of midget submarines for the delivery of drugs from Latin America (primarily Colombia) to Mexico, USA and Canada.
It is not easy to assess the situation in the world that has developed after the First world war. The defeated German Empire is the largest country in Western Europe fizzled out in the universal race of ambition and the fight for the championship. Near the bottom of the “pit” was Russia, which was drained almost six years of fighting and revolution. The formal winners — Britain and France suffered during the four years of the “great grinder” too great losses in men, and in the media. The role of a leading world power increasingly passed into the hands of “overseas uncle”. The future seemed vague and incomprehensible.
Tupolev SB aircraft was conceived as a bomber, overtaking fighters. It was natural to create a heavy fighter, designed primarily to combat the bombers. Total produced three prototypes of the SB. According to the decision of the meeting of February 14, 1934, one of them got American motors “Cyclone”, another French Hispano-Suiza, and the third was going to keep in reserve in the form of a set of units. Three days later appeared a decree of the Council of labor and defense (STO), which stated that the third prototype of SB should be equipped with the type of engine, which is better to manifest themselves on tests.
