"Ready for air defense" — (anti-aircraft and chemical defense of the USSR). This sign was established in 1935 at the request of the Central Council of Osoaviakhim. To receive the badge, a member of the Osoaviakhim had to be a striker in production and actively work on air defense and chemical defense in his home, factory, factory, collective farm, school, institution. In addition, the awardee had to pass all the standards of "Ready for air defense" and have his own serviceable gas mask. 
The sign had 2 degrees. Like the Voroshilovsky Strelka, in order to get a second degree, it was necessary to pass complicated standards. The number "2" is on the signs of the second degree. Due to the fact that these signs were produced in very large quantities at different factories, they come in a wide variety of sizes (from 25 to 40 mm. horizontally). The vertical dimensions depend on the length of the chains. In addition, there are signs made in the form of a suspension on a pad in the shape of a small airplane, but there is another type of badge — without a pad. These badges are smaller in size compared to the ordinary one, and they also come across both the first and second stages.
