How many missiles were at Engels airbase during Ukraine's attack? Expert opinion

Ukrainian drones attacked Russia's Engels airbase today, March 20, where the Russian forces may have stored dozens of missiles, stated aviation expert Kostiantyn Kryvolap in a comment to RBC-Ukraine's YouTube channel.
He noted that during the attack, no more than three Tu-95MS strategic bombers and two Tu-160s were likely stationed at the airbase. There is no information on their damage yet.
However, the situation with the missiles is different. A few days before the attack, an An-124 Ruslan cargo plane arrived at the airbase. Additionally, just yesterday or the day before, another cargo plane, an Il-76, was spotted there.
"It was calculated that the Il-76 typically carries around 7-8 missiles. Considering that a Ruslan was also there, the total number of missiles could indeed be in the dozens, possibly over fifty," Kryvolap suggested.
The expert also pointed out that it remains unclear whether Russia could have produced such a large number of missiles in such a short time. However, he emphasized that there was definitely a significant number of missiles at the airbase.
