NATO redeployed its aircraft against the backdrop of Russia's July 8 attack on targets in Kyiv.
"The Boeing KC-135T Stratotanker is flying towards the Polish border from the British Mildenhall airbase,” the Military Chronicle Telegram channel said.
The Boeing P-8A Poseidon anti-submarine reconnaissance aircraft and the Boeing E-3A Sentry aircraft equipped with the early warning and control system (AWACS) were also sent to Poland.
The Russian forces conducted a large-scale missile attack to strike targets in Kyiv and several other cities of Ukraine on July 8.
