These ships are similar to HSY-55-class gunboat and were also built by Hellenic Shipyards (HSY).

The first ship of the class, named Machitis (pronounced "Makhitis"), was commissioned on 29 October 2003.

On 17 January 2018, the second ship of the class, Nikiforos, was bumped by a Turkish Coast Guard patrol boat while patrolling in the Aegean Sea, close to the Imia islets.

The Turkish patrol boat was conducting dangerous manoeuvres which caused a slight collision of the two vessels.

[4][5][6] Turkish media reported the incident as well but without highlighting the bumping of the Greek ship.
