Armament

The BRP Rajah Humabon (PS-11) was a former destroyer escort of the United States Navy and a former frigate of the Philippine Navy. She was the last World War II-era destroyer escort/frigate active in her fleet, and one of the oldest active warships in the world, until 15 March 2018 when she was formally decommissioned after 75 years. She was one of three ex-USN Cannon-class destroyer escorts that served the Philippine Navy, the others being BRP Datu Sikatuna (PF-5/PS-77) and BRP Datu Kalantiaw (PS-76).
