Simple air defense would work at Engels
No need for aerostats or other such tools
There is no airfield on the planet that would have 100% detected such a threat early and destroyed it an enormous distance from the airfield... it is to Russias credit that they are shooting these drones down... in Saudi Arabia with all those fighter planes and all those AWACS and Patriots and other very very expensive systems they didn't even know they were under attack till the warheads exploded on target... and at the time they were at war with their neighbour so you can't use the they were not at war excuse.
Most countries don't have an IADS network and they will suffer even more from drone and cruise missile attacks... HATO does not have a unified air defence system... they have bits and pieces but not much to write home about... the only decent western air defence systems are on US Navy ships...
But have a good sulk... obviously Russia is in the shit and the sky is falling... if only the west wasn't so right about how evil and bad Russia and Russians were, if only Russia was a bit stronger so it couldn't care less what the west thinks...
It is the west that is in the shit... they seem to enjoy that... Russia is just shifting from the west and Europe to the rest of the world... let the west buy Russian energy and resources through third parties in the rest of the world who can profit from the wests arrogance and ignorance and refusal to interact with Russia... Russia wont care... it will sell products and resources because they have value and are needed... in the past it has been the west buying up that cheap energy for itself and being the middle man for Russian sales to everyone else making money on their trade... now the west can be in a different place in the queue.
