As Ukraine's air force dodges Russian missiles, the US and its allies are practicing to keep their jets flying while under attack

• Ukraine's air force has remained operational in the face of ongoing Russian attacks.
• It's able to do so largely because of its ability to disperse its aircraft and remain effective.
• That success has added urgency to US Air Force's own work on dispersing its aircraft and airmen.

After 18 months of attacks by Russia's bigger and better equipped military, Ukraine's air force is still intact and operational. While neither side can control the air, Ukrainian jets can still get airborne and attack Russian forces.
