This works in very limited locations for storage. are fueling and weopon loading done inside the shelters?
Attack and transport choppers that are numerous are parked in open. what about hundreds of transport aircraft.
Russia is large country missiles may not reach all the places but other smaller countries these shelters will be hit by missiles. and technology is moving so fast that the moment aircraft comes out of it will be detected.
now the there could be shelter for bombers who are in rear but you only use it for upgraded on and they are better at factory locations.
This particular incident where some places drones were intercepted and other not more look like favor to Zelensky as he personally took its ownership otherwise if Zelensky cannot show success by visible smoke coming out of the bombers Ukranians may have second thoughts about him.
