It was only recently when Britain decided to dispatch a bunch of troops in Estonia. This, of course, is related to  the strain there is between Britain and Russia. 

Considering the timing, the events that followed were more than shaky. Russia decided to deploy some of its submaries in Irish waters which of course are the seas of the UK. They were detected almost immediately and Britain decided to take action.

The Morning Ledger believes this to be a display of strength only from Putin's side but Britain already sent an escort ship to the group of Russian submarines in order to guide it back to its country while it goes through British waters.

The submarine from the Royal Navy being deployed is also said to be joined by another member from the North Atlantic Treaty Organization (NATO) and they are currently escorting the submarines back.

According to the Gamer's Drop, the Russian submaries are reported to be heavy-class war submarines and that does further fancy the idea of how Putin might want to show off his power to his opponents.

However it is somewhat odd how the submarines that were spotted were loaded with missiles. They were spotted twice by the Royal navy and then again up north. 

In fact, a few days ago a new submarine was introduced by Russia. A super stealth submarine which is essentially undetectable and it was mentioned by Russia how this new technology will be used and practiced in the Black Sea. The new submarine is called the Veliky Novgorod.

This again is not the end of the problems. This further declines the potential peace between Russia and England. In fact, apart from the Estonia facts, England is also pushing Spain to decline Russia's plead to land its aircrafts in the Spanish soil.
