Ukraine was able to destroy a submarine and a navy landing ship in dry dock but under the protection of several Russian S-400 anti-missile systems. It is interesting for how they succeeded because it effects how we think about China's air defenses. Ukraine defeated the S-400 anti-missile batteries and radar. Russia has about three times as many S-400 systems as China does. Each set is 8 launchers and 32 missiles. 16+ sets Russia and China bought 6 sets and has older S-300s. Ukraine was able to overwhelm the S-400s with drones, cheap S-200s and then anti radar missiles and then the UK Storm Shadow missile. $40 Million of attacking missiles beat $400-800 million of defending systems. China defending systems would be 3 times more costly. China bought from Russia and Russia charged a market price of about $500-625 million each instead ofthe $200 million cost to Russia. The UK Storm Shadow missiles are about $2 million each.
