A 3rd Isometric-EMM and an 8th Pentekonter-E are part of the order plus all ships will receive an upgrade with improved sensors, 360 CIWS and QPM launchers. A 5th Extender-E and 6 Coril-Es complete the order.
QPM uses the delivery vehicle of the TPM-1D married to a new warhead though the guidance and countermeasures suites are not as advanced.
