These naval CIWSs are massive. ~6 tonnes with a minute of ammunition. They cost tens of millions. All of this is probably acceptable for base defense.

But all high rate fire guns have short operation limits before their barrels melt. About 15 seconds before a 10 minute cool-off, maintenance and reload cycle. It's comically easy to saturate that with waves of decoy drones.

Those CIWS are designed to take out much more hardened targets than shitty drones. I bet you a shotgun shell can easily take out one of those drones.

Upgrade your drone defenses and now your drones cost more...

I don't work in the military so take everything I say with a massive grain of salt but I bet offense and defense scale in cost similarly and NATO + allies have WAY more money than the russians.

And note a big weakness of CIWS in port: what's your backstop? When the wave of drones comes in at low altitude over the city the port is at what happens???
