US Airforce F-22 Raptor deployed in Poland for training

Two military jet fighters F-22 Raptor, the most advanced and the most expensive jet fighters in the world, have arrived in Łask on Monday to undertake joint exercises with NATO allies."We continue to be concerned about Russian activity, which is evident (in Ukraine), and has been now for more than a year,” Defense Secretary Ashton Carter said on Thursday. The jet fighters began their deployment in Germany on Friday. They will go on to other parts of Europe for training exercises over the next month before concluding their tasks in mid-September. The sophisticated fighter jets, which cost about $143 million apiece are rarely shown outside the US.
