Purchase announced recently.

Rafale, F-16 and Gripen were considered.

Total cost: 900+ million EUR

This is strategically important to Croats in Bosnia-Herzegovina, who control around 20% of the country (autonomous cantons), as it allows the Army of Croatia to project a huge leverage onto the enemy who doesn't even have an air defense, and intervene with very little manpower and 0 casualties.

Well, 0 casualties on the Croatian side.

Comparison with F-35

A single F-35 costs $115 Million. And this is the price the US Army pays.
