The problem with those cutters is they are barely armed at all. There are measures in the works to remedy that, at least to a degree, but as they are now all they can do in a real war is serve as transports, and inefficient ones at that.
Armament
The ship was armed with a Mk.75 Oto Melara 76 mm Compact main gun, two Mk.38 M242 Bushmaster 25 mm chain gun at midships, and a Phalanx CIWS system aft. The CIWS and chain guns were removed by the US Coast Guard prior to its turn-over to the Philippine Navy. Only the Mk.75 gun remains.
Plans to install additional weapons were made, which includes one Mk. 38 Mod 1 25 mm chain gun aft, two Mk.16 20 mm autocannons midships, and six 12.7 mm machine guns. These were installed during its scheduled dock works before the commissioning ceremonies. Photos during the commissioning ceremonies confirmed the presence of such weapons.
The Philippines reportedly ordered at least four new Mk.38 Mod 3 25mm naval guns, and are expected to be installed on all Gregorio del Pilar class ships.
It was also reported that the Philippine Navy will be getting sophisticated radar system capable of detecting and tracking surface threats, a Harpoon anti-ship missile system, and torpedo decoy systems. This would be purchased from the United States possibly under a government-to-government deal.
Don't know how all that turned out, but...dang, I sure do like those ships. Very rakish. Probably prime duty for those sailors on it.
