The second possibility is more interesting. Snake Island is about 170 miles from the Black Sea Fleet’s homeport of Sebastopol. The maximum range of the Neptune anti-ship missile is also 170 miles.

If the second option is on the table, then what we are looking at here is a shaping attack that is removing the ability of the Russians on Snake Island to resist a Ukrainian air assault operation in preparation for a deep attack neutralize the Black Sea Fleet.

A mixture of Neptune and British Brimstone missiles on Snake Island could neutralize the Russian Navy in the Black Sea. With suitable supporting air defense units on Snake Island and the Ukrainian coast, It would also open the area to Ukrainian air force operations. Assuming that the Ukrainians can sustain the garrison, it could become an unsinkable defensive position that could put paid to any attempt by Russia to conduct an amphibious operation or exercise naval power in the war in Ukraine.
