https://news.usni.org/2023/05/29/philippine-coast-guard-will-hold-first-ever-trilateral-exercise-with-u-s-japanThe US Naval Institute News Service reports, beginning 1 June,
“BRP Melchora Aquino (MRRV-9702), BRP Gabriela Silang (OPV-8301), BRP Boracay (FPB-2401) and one 44-meter multi-role response vessel will conduct the exercise with National Security Cutter USGCC Stratton (WMSL-752) and Japanese patrol vessel Akitsushima (PLH-32).”
I will just provide some photos with links to the Wikipedia description of the vessels. Note none of the Philippine Coast Guard vessels have any permanently mounted weapons.
