The first ship was built in Germany and commissioned in 1992. 

On April 25, 2018 the Greek defense minister Panos Kammenos announced that the modernization of the four vessels is in progress but without presenting any further details about the program. 

These upgrades will include the following: eight (8) Close in Weapon Systems (CIWS) Phalanx BLK 1B Baseline 2 upgrade kits; four (4) MK 45, 5” 54 caliber gun overhauls; four (4) MK 49 Guided Missile Launcher Systems; four (4) COMBATSS-21 Combat Management Systems; and, four (4) AN/SQS-56 Sonar overhauls.

The proposed sale will improve Greece’s capability to meet current and future threats by providing an effective combatant deterrent capability to protect maritime interests and infrastructure in support of its strategic location on NATO’s southern flank. This acquisition, which will be awarded to the winner of an international competition for the Hellenic Navy (HN) MEKO Class Frigate Upgrade, will enhance stability and maritime security in the Eastern Mediterranean region and contribute to security and strategic objectives of NATO and the United States. Greece contributes to NATO operations in Kosovo, as well as to counterterrorism and counter-piracy maritime efforts. Greece will have no difficulty absorbing these articles and services into its armed forces.
