This was the second time in recent days that a US bomber approached Russia’s borders and appeared to carry out a bombing simulation, with the previous incident taking place on October 19. In that incident, Russian Su-27 fighter was scrambled to escort a USAF B-52H approaching Crimea.

A US B-52H Stratofortress strategic bomber has carried out a simulated bombing of the Russian Baltic Fleet’s base in the exclave of Kaliningrad, aircraft monitoring resource PlaneRadar has reported, citing tracking data.

Tweet reads: “15:40 Moscow Time. US Air Force Boeing B-52H Stratofortress strategic bombers, tail number 61-0025, call sign #BRIG01, took off from the RAF Fairford airbase is carrying out simulation of the bombing of the Baltic Fleet’s base.”

The resource’s map shows the bomber flying through the Baltic Sea, turning southeast into Lithuanian airspace, and approaching to within about 45 km of the Russian exclave to its east, over the Lithuanian town of Marijampole.

A day earlier, Russia’s Defence Ministry revealed that an Aerospace Defence Forces Su-27 scrambled from a base in Crimea to escort a B-52H which approached Russian borders in the Black Sea, with the jet reportedly shadowing the bomber at a distance of 70 km before returning to base.
