Denmark this month began training eight Ukrainian pilots in flying the jets, the Danish armed forces said.
Officials from a coalition of 11 nations have said F-16 training will also take place in Romania.
A Ukranian air force spokesman has said he did not expect Ukraine to be able to operate F-16 jets this coming winter.
Designed in the 1970s and produced in the 1980s by General Dynamics, now a part of Lockheed Martin (LMT.N), the F-16 jets that Ukraine will receive are around 40-years-old.
Russia warned that supplying jets to Ukraine would escalate the war.
