In response to a resurgent Russia, the U.S. Air Force is increasing its presence in Europe, including the possible deployment of the F-22 Raptor, according to the Air Force secretary.

“I could easily forsee the day … when the F-22 might rotate in,” Deborah Lee James told reporters at the Paris Air Show June 15, adding that she could not specify a date by which they would be sent.

The additional show of force will help counter Russia, which James sees as the “biggest threat” facing the U.S. She will leave the biannual air show to help reassure counterparts in allied nations across Europe. James will visit the U.K., where the U.S. has deployed B-2 and B-52 bombers; Italy, where the U.S. has sent unmanned Intelligence, Surveillance, and Reconnaisance (ISR) platforms; and Cyprus, where U2s are located. Then she will head to Poland for bilateral discussions.

“Russia is on our minds. It’s on the minds of our allies as well,” James says.

Gen. Frank Gorenc, commander of U.S. Air Force Europe, has been assigning active and reserve forces for exercises and has seen an increase in priority for the European theater. “This year we were able to prioritize two theater security packages,” one for the A-10 and another for the F-15. Those have focused on training, exercising and helping allies obtain training as joint terminal attack controllers.
