The development of drones forces us to look for new ways to strengthen air defense. The author of the Telegram channel "Russkiy Inzhener" Alexey Vasiliev proposed using Su-27 and Su-30 fighters to combat drones.
In his opinion, some of the aircraft could be restored at aircraft repair plants and used to create a unique air interception system. As weaponry, the expert suggests using R-27T and R-60 infrared-guided missiles.
However, retired Major General of Aviation Vladimir Popov stated that using heavy fighters against drones might be too expensive and ineffective.
The idea of using old Su-27s and Su-30s seems expensive and ineffective to me. An aircraft really won't detect every drone – they are often small. With larger models, such a trick might still work, but overall, it's simply impractical.
Popov believes that sending fighters to destroy drones is comparable to "shooting sparrows with a cannon."
