The Russians have discussed these "bases" before. This is really about rights to harbor, resupply and provide crew rest for Russian ships and so the Russians aren't really opening military "bases." This will allow Russian ships to deploy for longer periods and operate farther from their home ports.

As far as the missile goes, I have no idea. My Russian is very rusty, but the translation seems correct based on the Russian version of the article.

The newest Russian nuclear ballistic missile system is the Topol which means "Poplar" in Russian. Maybe Pravda got their trees mixed up. But even that doesn't make any sense - the Topol is an ICBM so there's no point in putting them in Cuba. And then there are the massive geopolitical ramifications of such a deployment.

No one else seems to have reported this missile deployment either. So, all in all, I think it's very likely that this is another case of Pravda not living up to its name....
