How to deal with 4 modern-class destroyers has become a headache for us. As long as we give in, Russia will definitely go crazy to snatch these 4 modern-class destroyers.

Because the Russian Navy hasn't had a new type of destroyer in service for over 30 years, and the only modern-class destroyer of the Russian military is basically in a state of paralysis.

The key is that the world’s technology is developing rapidly, and our 4 modern-class destroyers underwent deep upgrades in 2015. The outdated radars, air defense missile systems, electronic systems, and many other equipment from the 90s in Russia have all been dismantled. Everything has been replaced with advanced domestic systems.

The outdated air defense missile single-arm launchers have been replaced with vertical launch units for the Hongqi-16 air defense missiles, with the range increased from 30 kilometers to a sudden 100 kilometers. The huge "White Moth" large anti-ship missile launchers on both sides of the bow have been removed, and the AK-630M close-in weapon system has been uniformly replaced with a new type of combined missile and gun close-in weapon system, and so on.

In the entire Russian Navy's Pacific, Black Sea, Baltic Sea, and Northern fleets, there are actually no more than 4 warships with real regional air defense capabilities. Moreover, they are all based on Soviet technology from the 1980s.

If Russia can obtain 4 modern-class destroyers with more advanced regional air defense capabilities, it will be a huge improvement for the Russian Navy's surface fleet. The key is that Russia has long lost the ability to produce destroyers.
