This has created a strong technological base, which we have in these sectors in the correct scale and was not the beginning of the war. Our elektropribornaya industry, general purpose, aviapribornaya industry and, finally, marine instrument held by only a few factories in Moscow and Leningrad ( "electrical appliance", "Teplopribor" "Svetlana" in Leningrad, "Aviapribor" Lepse factory "Electrozavod" and " gauge "in Moscow). It is significant that after the war when we started to play the V-2 technology and design their new rockets, make sure that a long time mankind invented the device as electrical multicontact relay, is able to do in our country only one Leningrad factory "Red Dawn." In Germany, only the firm "Telefunken" There were three of these plant and at least two of the "Siemens". This is one of the reasons why, in spite of the continuous bombing, which the Federal Aviation subjected German cities, weapons issue did not fall, and continually increased until mid-1944.
