Large-scale work on designing a new main battle tank began in the USA after the termination in 1970 of the joint with Germany development of a promising tank МВТ70. In February 1972, the United States was formed the operative group, composed of military and representatives of the companies-developers. Their task was the formulation of a concept of the future tank ХМ1. The result of the work of this group was “Requirements for the material,” published in August 1972. A new tank was developed on a competitive basis. To participate in the competition, the Pentagon chose two companies: Chrysler and “GM”. 18 July 1974 was signed with them the contract to develop and manufacture prototypes of a new tank. Under the terms of the contract, prototypes were to be presented for testing by early 1976.
MAIN BATTLE TANK “ABRAMS”
Received in 1966 the US Army light tank М551 Sheridan made a splash among specialists. The case of aluminum alloys, 152-mm gun — launcher ATGM “Shillelagh”, the ability of the transport aircraft and parachute landing — it was all tanks for US, and for most light tanks the rest of the world a new word in the design and tactics of application. However, the value of these innovations were controversial, but it is not even that… All of the above is well known to many history buffs tanks. Much less known is that if the “cards lay” differently, the American army would get a completely different, though no less interesting light tank T92.
In 1987, the water came down, “LUN” the first ship of the series of combat missile-carrying wig weighing 400 tons was the Chief designer V. Kirillov was. The ship was armed with three pairs of cruise missiles 3М80 or 80M “Mosquito” (NATO designation SS-N-22 Sunburn). The second “LUN” is also laid as a missile, but the outbreak of the conversion has made adjustments, and it was planned to build as a rescue.

Only 30 years ago, no one could tell what it is, not to mention what wonders he can create. Times have changed. And today it is difficult to imagine a modern home or office where there is at least one such revolutionary inventions.
Someone impale them on sandwiches, someone makes them reduced copies of famous buildings, and some use them as intended, to remove stuck food between teeth. Welcome to the factory where they make modest zubachistca. Raw materials for toothpicks the most simple – logs, lots of logs, or rather of birch wood. The transformation of the Yule log begins with the separation of the bark, bark is not suitable for the manufacture of toothpicks, but it is not wasted, it is sold to a nearby factory where it is used as fuel. The log is processed on the machine twice, the result takes the form of a right cylinder, convenient for further processing. A special machine turns the log like a roll of paper simultaneously slitting thin layers dvenadtsaty sharp blades.

On the globe there are numerous plots of land that has an extensive Maritime border and a significant number of inland waters. To the greatest extent meet these criteria Canada, North Eastern United States, Australia, New Zealand, the Asia-Pacific region, Latin America, the Caribbean, Siberia and the far East of the Russian Federation. All these and other island territories represent the most promising market for light aircraft amphibians, especially because in most of the above countries and regions already have experience of using this technique. Today in operation there are a few thousand light seaplanes and amphibians.
Float glass is the basic product of the glass industry is a colorless , transparent, mirrored or tinted sodium-calcium-silicate glass manufactured by methods of float or vertical extraction without any additional surface treatment having the form of flat rectangular sheets whose thickness is small relative to the length and width. Typically use glass with a thickness of 1.9 to 19 mm.
