The Ukrainian account DeepState, which studies publicly available data, according to Defence Ukraine, has processed a huge amount of data in order to create a detailed map of the areas occupied by the Russian army in Ukraine, with an emphasis on the extensive Russian fortifications.
To do this he analysed countless satellite images of the Ukrainian military map. The result is an interactive map, which is accompanied by many statistics and data collected by the site.
Vast Fortified Areas
More specifically, the total fortifications of the Russian army in Ukraine are 6 thousand kilometers or 3,700 miles long. They extend from south to east, crossing the Kherson region (886 kilometers), the Zaporizhzhya region (1,869 kilometers), the Donetsk region (1,865 kilometers), the Lugansk region (1,140 kilometers) and of course Crimea (265 kilometers), and ending deeper in the direction of the Russian Federation. And of course we are talking about the new fortifications created from the beginning of the war in 2022 to the present day, not those created since 2014.
Taking into account that the current active line of contact between Ukrainian and Russian forces is about 1,500 kilometers long, we are practically dealing with about 4 kilometers of fortifications per kilometer of front.
Of course, we must stress that fortifications vary from region to region. For example, in the region of Zaporizhzhya, and in particular in the corridor between Melitopol and Berdjansk, there are 410 kilometres of dragon teeth and 514 kilometres of anti-tank trenches, which are included in the total of 896 kilometres of trenches. On the other hand, the Donetsk region currently hosts 1,285 kilometres of trenches, accompanied by only 269 kilometres of dragon teeth and 282 kilometres of trenches.
There are many reasons why the fortifications differ but the main one is the terrain in each region. The southern regions of Ukraine have areas that are more vulnerable to tanks and need to be fortified with trenches and anti-tank concrete pyramids called dragon's teeth.
The DeepState account adds that the Russians are trying to hide some of their fortifications, making them completely underground. Be that as it may, however, DeepState's newest reports contradict earlier estimates by Reuters, which had estimated that the Russians' fortifications extend over 1,000 kilometers.
If DeepState's data is true, then it is almost impossible for the Ukrainian army to overcome all these obstacles, no matter how long they prepare.
