Apparently, Ukrainian drones pushed through and started a chain reaction.
Explosions reportedly continued for hours, and authorities evacuated nearby settlements. Initial reports indicate that the site, previously protected by one of Russia’s densest air defense networks, suffered catastrophic damage.
I would confidently assume 100% of it was munitions
If you think of the fill percentage, I think that’s too optimistic, since they’re in a war. There is constant demand. However, even 50% would be an extremely big amount, and relieve Ukrainians from a lot of pressure (last year, when a similar thing happened in Toropets, it had effects on the front within weeks). This time, from the videos I saw, there was enough to keep detonating for a long time.
Whatever the fill percentage and loss percentage, the site is closed for a long time - if something remains, it cannot be reached, it has to be examined and re-certified. But more likely, very little will remain.
In the coming days, satellite photos will tell what the situation is.
I think they meant 100% of the explosions were munitions, not 100% of the munitions exploded. 'Twas a joke.
