Four US F-22 fighter jets have arrived in Poland for the jet's first-ever training deployment to Europe.

美国四架F-22战斗机已经抵达波兰进行该机型在欧洲的首次训练部署。

The stealth tactical fighter aircraft will train with allied air forces and U.S. services through mid-September.

The Pentagon is describing the deployment of the F-22 as a broader effort to support eastern European members of NATO unnerved by Russia's actions in Ukraine.

The US Air Force has previously deployed the radar-evading jets in Japan and South Korea, but not in Europe.
