Power of artillery and volley firing range, these ships had a significant advantage over the latest at the time of the German destroyers series and 2 American style “Bristol”.
In 1921 – 1939 in Leningrad acted Special technical Bureau for military inventions (Sptecbureau), it was headed by engineer V. I. Bekauri. In 1934 in a 1st division Sptecbureau was formed by a group of dedicated submarines. Her first project embodied in the metal, was the midget submarine APSS (aerobody self-propelled projectile), representing odnostolpnoy the boat-the torpedo with a displacement of 8.5 tons. APSS was controlled by radio (VHF and LW) during visual tracking of a plane or ship. There was a possibility and manual control.

The first prototype flew on 16 August 1952 mass production of the Britannia was carried out between September 1954, However, forced landing in Uganda in operational trials in March 1956 delayed the introduction of the aircraft on regular routes.

After her victorious Russo-Japanese war, Japan immediately moved to a new class of naval powers, occupying one of leading places. After the commissioning of the trophies of the Russian fleet was owned by quite an honorable fourth place in the world. But the number greatly exceeded the quality. Especially noticeable is the discrepancy was in the class of cruisers. In 1907, the Navy of the Mikado consisted of 25 units of this class — the number of earned the respect. But they all were outdated. Suffice it to say that the largest and most modern light cruisers was a former “Varyag”, which received a new name — “Soya”. He and his colleagues were a bunch of various ships that were built in all major marine countries. Even played an important role in the battles of the last war armored cruisers in a couple of years moved into the category of “linear” units is not the second but rather the third line.
The victory of the Soviet troops in the forty-second and forty-third years had tipped the scales of war in our favor. The enemy got an object lesson.

Off-road combat and transport battalions, equipped with the appropriate types of planes, got into the hands of one of the main trumps of the war — the mobility and speed of movement. In the most unexpected for the enemy areas is rapidly emerging, and conducted a successful combat operation of our units. The enemy were guarding the road — snowmobiles appeared due to impassable snow drifts. The effect of surprise, the transience of the battle behind enemy lines produce a striking effect on the Nazis.

In February 1941 Aviatsionny corps of the U.S. army (the predecessor of the air force, U.S. army) became interested in the possibility of using gliders in the landing and transportation operations. As a result, by March 1941, developed the preliminary requirements for two types of gliders for the transport of eight and 15 people. These requirements sent to eleven firms, but only four of them said that they are ready to start work. It was “the Frankfort, sailplan company”, “Waco aircraft company of Troy”, “Bowles, sailplan incorporated and the St. Louis aircraft Corporation”. Other refused to participate in the contest, being involved in the implementation of other military orders, or citing the lack of necessary capacity or experience. To the stage of construction of prototypes of the gliders made it two companies.
