- Ukraine is set to receive its first F-16 fighter jets from its Western partners this summer.
- But the exact number of planes is unclear, and Zelenskyy said it likely won't be enough.
- He compared the problem to Ukraine's Abrams tanks, which it only got 31 of and hasn't used much.
Western-provided F-16 fighter jets are on their way to Ukraine and set to start flying missions later this summer.
