In September 2021, Greece signed an agreement with France's Naval Group to purchase three FDI HN frigates with an option for one more for the Hellenic Navy as part of a €3 billion ($3.34 bn) defence package.

[13][14] In February 2022, documents released by the Greek Parliament indicated that initially the first two frigates for the Hellenic Navy would be equipped similar to their French counterparts in a "Standard-1" configuration (with 16 Sylver A50 cells).

[15] As of January 2023, 23 contracts had been signed with Greek companies participating in the frigates' construction, with 10 more during the same year.

[19] It was unclear how this reallocation might impact the original intent to have the third Greek FDI built in an enhanced "Standard-2" configuration.

[10] These names had previously been used for the ex-US Charles F. Adams-class destroyers in service with the Hellenic Navy from 1991 to 2004.
