It was initially designated as Fast Patrol Craft, but later on was re-designated as a Patrol Gunboat "PG-393".[1] Another round of reclassification was made in April 2016, which re designated the boat, from patrol gunboat to coastal patrol craft "PC-393".
The ship was built to US Coast Guard standards with aluminium hull and superstructure. She is powered by two Detroit Diesel 16V-92TA Diesel Engines with a combined power of around 2,800 hp driving two propellers for a maximum speed of 28kn. Maximum range is 1200nmi at 12kn, or alternatively 600nmi at 24kn.
The ship originally designed to carry one bow Mk.3 40 mm gun, one 81 mm mortar aft, and four 12.7 mm/50 calibre machine guns. Instead, she is armed with one 25mm Bushmaster chain gun on Mk.38 Mod.0 mount, four M2HB Browning 12.7 mm/50 calibre machine guns on Mk.26 mounts, with two positioned forward and two aft; and two M60 7.62 mm/30 caliber machine guns, both mounted amidships. The ship can carry 4,000 rounds of 12.7 mm and 2,000 rounds of 7.62 mm A large "Big Eyes" binocular is also carried on tripod mounts, one on the forecastle and one just above the mast.
As part of the third batch (PG-392 to PG-393), it is equipped with Mk.38 Mod.0 M242 Bushmaster 25mm chain gun that the first batch of ships do not carry.[3]
She is equipped with a Raytheon AN/SPS-64(V)11 surface search and navigation radar but with a smaller antenna as those used in bigger Philippine Navy ships.[2] Like all other Philippine Navy ship, she was installed with the Philippine Navy Vessel Tracking System (VTS) by the Naval Sea Systems Command.[4]
A 4-meter rigid inflatable boat powered by a 40-hp outboard motor is stowed amidships.[5]
