The US Department of Defense said that the F-35A Lightning II fighters are sent to Europe to conduct training for several weeks as part of the European Reassurance Initiative.
"The US Air Force will deploy a small number of F-35A Lightning II aircraft this weekend on a long-planned training deployment to Europe," US Department of Defense said in a release on Friday.
The Pentagon said the deployment represents "natural progression" of the F-35 program and would allow to demonstrate operational capabilities of the jets.
"It also assists in refining requirements for eventually basing the F-35A in Europe, which is scheduled to receive the aircraft in the early 2020s," the release added.
Three variants of the F-35 jet are being introduced into the Air Force (F-35 A), Navy (F-35C), Marines (F-35B).
F-35 jets are set to be deployed to Europe on a permanent basis in the beginning of 2020s.
The creation of the European Reassurance Initiative (ERI) was announced by US President Barack Obama in 2014 as an alleged response to the "Russian threat." The ERI was established in the 2015 budget as a one-year, $1 billion emergency response.
