Norwegian Defence Minister Bjoern Arild Gram announced on Wednesday that Norway will assist training programs for Ukrainian pilots to fly F-16 fighter jets.

On Friday, US Vice President Joe Biden authorized training programs for Ukrainian pilots on F-16 fighter jets, and Ukrainian President Volodymyr Zelenskiy assured Biden that the planes would not be used to enter Russian territory.

“The government backs this initiative and is considering how Norway can contribute together with allies and partners,” Gram said.

The Norwegian government has not decided whether Norway will give any of its F-16 jets to Ukraine, the minister separately told public broadcaster NRK.

Russia, whose forces invaded Ukraine 15 months ago, has said any transfer of the U.S.-made F-16s to Ukraine would be pointless and raise the question of NATO’s role in the war.
