At any exhibition there are always centers of attraction of attention of visitors. There was a and in the Central exhibition NTTM-87: it was — as, indeed, in all previous aviation section of the exhibition. This is no coincidence: today, in many parts of the country, the young enthusiasts of technical creativity to build a homemade aircraft. They closely follow the latest developments not only Amateur ultralight aircraft, but the cruise technology, which is created in the famous design Bureau. As, for example, became the favorite of heaven acrobatics at the last European Championships and the world aerobatic su-26M, one of the most popular exhibits NTTM-87.

The debut of the first Soviet diesel truck yaz-200, developed at the Yaroslavl automobile plant, held in 1945, was successful. After the traditional show of the new machines in the Kremlin party and state leaders of the country truck recommended for serial production.
British military shipbuilding has centuries-old experience of development and combat use of the most advanced designs and technologies. On the eve of the Second world war-the British squadrons were surface ships: battleships, battlecruisers and aircraft carriers. Therefore underwater vessels by the Admiralty was not honored. However, the attack on Gunter Prina 15 Oct 1939 in Scapa Flow, when he crept into a German submarine sank the battleship right into the main base of the British Navy, put squarely the question of creating subversive underwater vehicles.
By the spring of 1943 in the fighting at the front emerged a qualitative leap in improving the combat capability of the German armored vehicles. There are new tanks Pz.Kpfw.VI “Tiger” with the 88-mm gun and a PZ.Kpfw.V “Panther”, which had 75-mm gun. For tanks T-34 and KV-1 to the red Army’s main opponents on the field of battle were T-IV with short-barreled 75-mm gun. 80-mm frontal armor easily able to get our armor-piercing shells.
We left two outstanding inventors, John Holland and Edmund Zelinskogo, in 1886 in a pretty sad state. The firm of submarines collapsed simultaneously with the physical collapse of the pile with their first and only joint design. The money ran out, wanting to continue the experiments there. Holland seems to be had only to retrain for something less exotic. But he wanted to build submarines. And then he undoubtedly is lucky of different European countries already reported quite promising boats, capable long enough to be under water and attack the enemy. Blow to the Naval Ministry USA, stubbornly wanting to adopt none of the samples, which we described earlier, was the news that his “secret vessel” motor is going to build Spain. The relationship between one of the oldest colonial powers and the young American “democracy” is active on these colonies looked, was getting worse and worse. And congressmen finally decided to fork out.
The Washington naval agreement of 1922 was a significant barrier to growing the race for naval armaments, which began during the First world war. Under this agreement the Japanese fleet by number of aircraft carriers and capital ships (battleships, cruisers) are much smaller than the fleets of England and the United States. Some compensation for this could serve as a permit for the construction of the points of forward basing in the Pacific Islands. And because agreements about the number of submarines to achieve in Washington and failed, the Japanese admirals began to plan the placement on remote island bases of small coastal boats.
Autumn the evacuation of 1941, which resulted in the defense enterprises of the capital was transferred to the East of the country, has transformed a provincial town, which was the Ulyanovsk, Chelyabinsk and Miass, in the largest industrial centers, producing goods for needs of red Army. Thus in the Urals city of Miass appeared one of the most powerful Soviet enterprises for the production of military vehicles.
While the British Admiralty systematically extinguished the enthusiasm of its inventors-“submariners” in former British overseas colonies, and now the most economically powerful nation in the world, energetic engineers to continue their experiments. And, in the end, the United States has become the birthplace of real submarines, suitable not only for experimentation and advertising “horror stories” in the spirit of sir Basil Zaharov, but also for combat use.
Passenger aircraft DC-2 and DC-3, developed by the designers of the American company “Douglas” in the middle 1930s was extremely successful, was built in large numbers and spread throughout the world. But made on the basis of their bombers is not known by the time of the US entry into the Second world war has practically disappeared from combat units. But first they had high hopes…
The Shorland armored car (“Shoreland”) – joint development of Irish firms of Short Brothers and Harland (“Short Bros & Harland”) by order issued in 1961 Royal police force of Northern Ireland. According to the requirements of the armored car should be very simple, and its development is minimal time.
