On 25 September 2008, a 299 million Euro contract was signed between the Greek State and the Elefsis Shipyards for the construction of the two remaining vessels of the class, P-78 and P-79.

Due to serious financial problems of the shipyards and the Greek state, there has been a 10 year delay in the construction of the two ships.

They are complemented by an Otobreda 76 mm naval gun in the bow and two smaller 30mm cannons as secondary weapons located on the ships' superstructure.

[10] The sensor suite responsible for the timely identification and homing of surface and air targets includes the MW08 3D G-band surveillance radar, the Mirador electro-optical target tracker and the Scout MkII low probability of intercept radar which is being controlled by the TACTICOS combat management system.

The ships of this class are named after junior officers of the Hellenic Navy who have been killed in action.
