The Third Reich is still strong.
Hitler decides to go all in and launch a new, decisive offensive that will determine the fate of the war.
A squadron of ships of the Russian Navy, led by the aircraft carrier Admiral Kuznetsov, is sent to the shores of Syria. But instead of the Mediterranean, it ends up in the Black Sea, where it fights the besieged German troops at besieged Sevastopol, while the Red Army lands troops in Crimea, trying to break the main base of the Black Sea Fleet free. People from the 21st century, without hesitation, stand with their ancestors and go into battle against the enemy.
Crimea is already liberated, Leningrad is unblocked—Soviet troops slowly but surely push the enemy back to the border of before the war.
