The ship, called the Ambal, is currently at sea moving towards Kaliningrad, where it is expected to arrive today Friday.

The possibility exists that the violation of Estonian airspace by a Russian military plane on Thursday is connected to the move.

Asked by ERR’s Estonian news portal if he could confirm, Minister of Defence Hannes Hanso (SDE) said that they had their own channels to answer such questions. “But it’s certainly true that we have reason to keep our eyes open in the air, on the water, and everywhere else,” Hanso said.

Asked if the airspace violations that occurred in Finland and Estonia on Thursday and Friday could be connected to Russia’s move, Hanso said that this possibility couldn’t be excluded.

Iskander-M is a ballistic rocket system designed to destroy strategic targets in a distance of 500 to 700 kilometers.

In 2010 and 2011 the Russian 26. missile brigade around Lake Peipus was equipped with rockets of this type (12 positions in total). According to magazine Diplomaatia, it is likely that the Iskander system was introduced to the 152. missile brigade stationed in Kaliningrad in 2012 and 2013.

The Iskander system is intended for the destruction of strategically important objects, such as airfields, ports, railroad junctions, military headquarters, and so on. From Kaliningrad, the range of the system reaches from southern Poland to central Finland, ERR News writes.

Airspace violations in Finland and Estonia on Thursday and Friday

A Russian Su-27 fighter jet violated Finnish airspace at 4:43 p.m. on Thursday, and again at 9:33 p.m., the Finnish defense ministry reported.

A plane of the same type violated Estonian airspace close to the island of Vaindloo in the Gulf of Finland at 2:38 a.m. on Friday. The jet was on Estonian territory for less than a minute, the Estonian Defence Forces reported. A flight plan had not been filed, and the plane’s transponder was not active.

The Ministry of Foreign Affairs summoned the Russian ambassador on Friday to hand over a protest note.
