Site's down atm but he does mention towards the end 28+ missiles would've been necessary to start overwhelming the Moskva's defenses. I think it's unlikely they had that many in place to fire at it simultaneously. The launchers for it aren't exactly small and can only carry 4 each AFAIK.
It wouldn't be that surprising if the navy was corrupt and inept as well. The weather conditions, the command structure, and the fact that it was night time could have also played into it. If the people on watch were tired, it could have slowed reaction times. If they weren't allowed to launch counter measures without the captain and the captain was sleeping, it could have slowed reaction times.
I would assume it's a combination of poor readiness, poor training, poor leadership and a high pressure/stress environment due to the drone harassment.
> 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.
