  • Ukraine's F-16s now look set to arrive when they can be particularly impactful.
  • That's because they'll arrive when Ukraine has permission to use other weapons on targets in Russia.
  • This means that Russian air defenses that could target them can be taken out, experts told BI.

New rules from Ukraine's allies about how it can use weapons they've supplied could have a strong impact on its long-awaited F-16s.

The first of the US-made fighter jets are due to arrive this summer, at a time when they can be particularly impactful in the fight against Russia, experts told Business Insider.
