The photo shows that the length of the crack on the Dozor-B armor is such that there is not enough 30-centimeter ruler to measure it:
On the Online Ukroboronprom appeared official comments. And in these comments are found attempts to justify the marriage in the production of armored vehicles. One of such attempts belongs to the chief engineer of the Lviv armored plant (it was at this plant that Dozory-B was made) Igor Churilov. According to him, there were problems with welds, since "the difficulty was the task of mastering the welding of bronestali."
It turns out that Lviv welders were not even familiar with this kind of technology, but they were already instructed to carry out work on welding armor plates for Dozorov-B.
Here thermal conditions are very important, the metal is cracked. These tests we passed firmly, and now the technology is mastered.
And representatives of the Ukroboronprom declare that the process of creating “Dozorov-B” took place in “record time”. This, apparently, must be considered the main reason for the fact that the “newest” Ukrainian armored vehicles are splitting at the seams, without passing the 200 km from the factory to the military unit.
From the statement of the head of the Kharkiv Morozov Design Bureau Yakov Mormilo:
Work is in full swing, because these armored cars are our independence.
The photo above illustrates this "independence."
