> Never seen it discussed, but maybe the drone landed a bomb on the superstructure which knocked out their radar or other detection systems.
But that's also ridiculous: a cruiser, with full anti-air capabilities, would be disabled from an aerial bomb?
Missile-defense is harder than anti-air (especially vs slow, non-stealthy aerial drones). It makes far more sense that Moskva failed against the sea-skimming missiles, rather than the obvious drone in the vicinity.
Then again: the Moskva *should* have been able to disable the missiles.
