Here's an interesting article about how the sinking of the Moskva opened up Snake Island to attacks by Ukrainian drones. It also seems to have interfered with Russia's use of landing ships.
>>>The biggest impact of the loss of the cruiser Moskva is that the northern Black Sea is a safer place for Ukrainian aircraft. Particularly for the Ukrainian Navy’s TB2 drones. This tactical loss could have strategic implications. . . .
Ukraine’s first major move appears to have been to take out the air defenses on the island with a drone strike. A potent SA-15 Tor missile system provided local air defenses, at least in theory. The removal of that system allowed the Ukrainian Navy’s TB2 drones to loiter nearby. The first Russian Navy victims were two Raptor assault boats on May 2. . . .
On May 7 Russia attempted to land a replacement SA-15 missile system on the island. A TB2 drone caught the Pr.11770 Serna Class landing craft in the act,
hitting it as it was about to unload. The attack was devastating and the shipwreck blocked the landing spot.
With the air defenses degraded the Russian garrison was subject to successive air strikes by drones and fighter jets. Soon most of the buildings on the island were reduces to rubble. Russia was still operating Raptors in the area but two more were eliminated by a TB2 on May 8. Along with a helicopter landing troops on the island. The island seems unlivable.
But it isn’t over, Russia appears determined to hold the tiny piece of strategic real-estate. On
May 9 another landing craft, a slightly larger Pr.21820 Dyugon class, was observed next to Snake island. We assess that this was likely attempting to deliver yet another SA-15 Tor air defense system. . . .
Something we haven’t seen operating around Snake Island in recent weeks are the large landing ships. In the first couple of months of the war one or two of Ropucha Class landing ships were frequently observed near the island. . . .
In late April, after the Moskva sinking, there was a change in the patterns however. We stopped seeing the Ropucha near Snake Island. While we cannot be certain, with open sources, that they have entirely stopped, all indications are that they have. Instead we have seen Raptor class assault boats and smaller Dyugon and Serna class landing craft used.
The straightforward interpretation is that with Moskva gone, it became too dangerous for them.<<<
