Once the F-16s are place, the challenge facing Ukraine will be when and where to use these valuable resources - and how to avoid them being destroyed before they can contribute to the Ukrainian defensive effort.

They will provide Ukraine with an invaluable - albeit scarce - resource. The F-16s could be used to support the frontline, but they will be very vulnerable in that dynamic and hostile air environment.

They could also be used to conduct strikes against key military targets inside Russian territory, which would certainly force a change in Moscow's tactics. Or, if Ukraine wanted to threaten Crimea, the F-16s could be used in a coordinated attack in support of a wider campaign.
