By that time, the deployment of the echeloned Moscow air defense zone had already been fully completed. More than 500 air surveillance, warning and communication posts 200-250 kilometers from the city center informed the headquarters in advance of the approach of enemy aircraft, and the fighters had time to intercept. The sky of the capital was protected by more than 600 aircraft, 1,044 anti-aircraft guns, 336 anti-aircraft machine guns, 618 anti-aircraft searchlights and 124 barrage balloons.
Masking was widely used in the city. Trees and roofs were painted on the streets and squares, the golden domes of the Kremlin cathedrals were painted in camouflage tones, the red stars on the Kremlin towers were wrapped in tarpaulins, and contrasting stripes were applied to its walls, giving them the appearance of ordinary residential buildings. Lenin's Mausoleum on Red Square was closed with shields so that from the air it looked like a two-story house. Platforms with models of buildings anchored to the Moskva River were brought out.

On the approaches to the city, eight new RUS-2 radars were operating, scanning the western and southern directions. It was one of these stations on July 21 at 21:00 that reported the approach of a large group of bombers.
"The enemy flew very brazenly that night," recalled Soviet test pilot Mark Gallai, who participated in repelling the raid. - Hitler's bombers went at low altitudes -two, three, four kilometers at most. It was as if they did not even in their thoughts admit the possibility of active resistance on our part. A few days later it turned out that this was the case. The captured pilots from the downed German planes said that, according to their intelligence, with which they were familiarized before departure, they should not have met a serious air defense system and, in particular, organized night fighter aircraft over Moscow."
