Service history
In 1987, she was commissioned into the ROK Navy as the ROKS Chungju (PCC-762). She was decommissioned in December 2016, after decades of service.

On 5 August 2019, she was officially transferred to the Philippine Navy and was commissioned into service the same day at the Jinhae Naval Base. She was named BRP Conrado Yap (PS-39), after Philippine Army Capt. Conrado Yap who fought in the Korean War.

The ship is optimized for anti-submarine warfare missions. She will be used to build anti-submarine warfare (ASW) capabilities of the Philippine Navy, along with the newly acquired ASW helicopters. Prior to these, the Philippines lacked any ASW capability in a region where the number of submarines being operated by neighboring countries was reportedly set to grow.

On 17 February 2020, BRP Conrado Yap encountered the People's Liberation Army Navy Type 056A corvette Liupanshui on its patrol mission. Crews of the Conrado Yap visually observed Liupanshui's gun control director pointing at them.

On 26 November 2022, Conrado Yap conducted a Goodwill Exercise with JS Harusame in the vicinity of Subic.

As of 2024, Conrado Yaps hull number was changed to PS-30' according to its official facebook page.
