Russian fiber-optic FPV used to strike transformer under protective 'sarcophagus'

The post claims a Russian operator used a fiber-optic FPV drone to penetrate a hardened protective shelter (“sarcophagus”) and destroy a 330 kV autotransformer at the Sumy substation. The notable element is the use of fiber-optic FPVs for precision strikes against protected infrastructure, implying resilience to RF jamming and the ability to maneuver into/through covered structures.
