In May 2009, the Carlos Albert, together with other Philippine Navy ships BRP Dagupan City (LC-551), BRP Bienvenido Salting (PG-112) and other Philippine Navy units, joined their United States Navy counterparts including USS Harpers Ferry (LSD-49), USS Chafee (DDG-90), USS John S. McCain (DDG-56), USNS Safeguard (T-ARS-50) in the CARAT 2009 naval exercises [3]
In May 2018, the BRP Carlos Albert intercepted and seized two Malaysian-registered Fishing Vessels together with its crew of 20 Vietnamese personnel carrying over 50 endangered species of Sharks and Rays off the coast of the Mangsee Islands.[4]
In October 2018, the ship was conducting regular patrols when it spotted and intercepted the Andrea 3 off the coast of El Nido, Palawan at around 12:35 pm at 8 nm or within the Exclusion Zone of the Malampaya Natural Gas Platform. The crew of the Andrea 3 were also later found to be using Compressor Diving for fishing which is illegal. They and the Andrea 3 were brought to the Liminangcong Pier in Taytay, Palawan and turned over to the custody of the Bureau of Fisheries and Aquatic Resources (BFAR).[5]
The ship was built to US Coast Guard standards with aluminum 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 caliber machine guns. Instead, she is armed with only four M2HB Browning 12.7 mm/50 caliber 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 first batch (PG-370 to PG-378), it is not equipped with Mk.38 Mod.0 Bushmaster 25mm chain gun.[6] It was planned to install either a stabilized or unstabilized M242 25 mm Bushmaster chain gun on her bow after some minor modifications, but as of to date has not materialized.
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]
A 4-meter rigid inflatable boat powered by a 40-hp outboard motor is stowed amidships.[7]
