Ukrainian military spokesman Andriy Lysenko has reported 27 January that Ukrainian military forces have destroyed around a dozen military airplanes and helicopters in the possession of militants in east Ukraine:

"We haven't shot the aircraft down. Planes and helicopters have been destroyed while on the ground on the territory of an east Ukrainian airfield which has been seized by militants. The operation was carried out in order to prevent militant forces from using these aircraft. Everything we have identified has been neutralized. If we identify further militant aircraft we will neutralize it also,"

Earlier in January Lysenko announced:

 "The armed groups of the so-called LPR have announced the creation of their own air forces, consisting of two planes – Su-25 jet aircraft and L-29 jet trainer aircraft,"
