Lockheed Martin F-35 Lightning II

The Czech Republic has signed a $6. 5 billion deal to purchase 24 F-35 fighter jets from the United States, the most expensive purchase in the history of the Czech armed forces. The fighters will begin arriving in 2031 to replace the country's current fleet of JAS-39 Gripen jets leased from Sweden.

Greece has decided to give Ukraine outdated weapons systems that are no longer used by its military. This comes after the United States approved the sale of $8.6 billion worth of F-35 fighter jets to Greece and offered additional military aid of $200 million if Greece provides the weapons to Ukraine.
