Not sure if these are F-16A/B's or surplus F-16C/D's, but would assume A/B's?
The Croatian National Defense Council said on 27 March 2018 that the Croation Minstry of Defense should accept Israel’s offer to supply its air force with surplus Israeli Air Force F-16s.
Last year, five countries - Greece, Israel, Sweden, South Korea and the United States - were asked to tender a new fighter in the Croation request to replace the eldery MiG-21 fleet of the Hrvatsko ratno zrakoplovstvo i protuzračna obrana (HRZ i PZO, (Croatian Air Force).
