According to CNN, the US Department of Defense Pentagon has been following the two Iranian warships for about two months.

They had then rounded the Cape of Good Hope and were thought to be about to cross the Atlantic.

The United States first suspected that it would supply Iranian weapons to Venezuela.

But then they changed course towards the Baltic Sea.

The Danish Defense Command now confirms to SVT Nyheter that the Iranian ships are in place in the Baltic Sea.

- The Iranian ships Makran and Sahand crossed the Danish strait yesterday and are now in the Baltic Sea, says Sören Damm Möller Lindhardt, press spokesperson at the Danish Defense Command to SVT Nyheter.

"Hard to see what's on board"

Makran is a so-called base vessel that became operational at the beginning of 2021. It is a rebuilt oil tanker with several areas of use, says FOI's expert on naval forces, research leader Niklas Granholm.

- You can have it as a helicopter base or have marines on board.

You can have it as a bunker for other battleships so that you get a range and flexibility that you do not normally have.

And what can it transport?

- It is difficult to see what is on board.

It can be hidden.

Small submarines for example?

- You can imagine that.

First visit

According to Niklas Granholm, this is the first time that Iran's navy is in the Baltic Sea.

It is the second Iranian battleship is the frigate Sahand.

- This is seen as a sign of deepened military relations between Russia and Iran.

They have common interests.

The Iranian ships are invited to the naval parade in St. Petersburg on Sunday, which will be the largest to date.

Ships from India and Pakistan are also participating.

The holiday has been celebrated for over 325 years.

And this year, Russia has taken in three nuclear-powered strategic submarines with robots that are likely to be equipped with nuclear weapons.

It has never happened before.

- It is a change in the defense and security policy environment we should observe, says Niklas Granholm.

Nuclear weapons on board

Since 2017, a strategic Russian submarine has participated in the annual naval parade on the last Sunday in July.

On Friday, the three strategic submarines were in the Gulf of Finland.

But are they sharply charged with nuclear weapons?

- They do not say that.

It must be assumed that they are.

The point is that they should be on standby at all times.
