OSINT researcher Dzhambov notes that the Russians have created another semi-ring of frantic air defense around Putin's Valdai residence. The new ring has a radius of about 55 kilometers around the residence, with the distance between towers being about 15 kilometers. Some towers cast a longer shadow - the researcher admits that they may be somehow different from the others, but is not sure of the reasons. Construction of all the towers began simultaneously in the first week of September. Some of the towers have a dual purpose: they cover not only the residence, but also facilities such as a substation and an airport in Demyansk. The total number of towers found by the researcher is 16, so Putin's residence is already covered by 49-50 air defense towers.
