BRP Emilio Jacinto (PS-35) is the lead ship of the Jacinto-class corvettes currently assigned to the Offshore Combat Force of the Philippine Fleet.

They also worked with the Marine Department of the Hong Kong Police and with Customs & Excise in order to prevent the constant flow of illegal immigrants, narcotics and electronic equipment into the Colony.

[3] Emilio Jacinto was part of the Philippine Navy contingent to join CARAT 2004, together with her sister ship BRP Artemio Ricarte.

This was followed immediately with a separate exercise with 2 British Royal Navy ships, namely HMS Exeter and RFA Grey Rover.

[10] In April 2020, Emilio Jacinto delivered relief goods for patients under investigation (PUIs) and persons under monitoring (PUMs) in the remote municipalities of Mapun and Turtle Islands in Tawi-Tawi.

[12] The ships under this class are characterized by a low freeboard, an Oto-Melara 76 mm gun turret located forward, large funnel amidships and a crane and rigid-hulled inflatable boat (RHIB) aft.

The Oto Melara 76 mm Compact DP (Dual Purpose) gun is the primary weapon and is mounted in a turret forward of the bridge.

The ships were modified soon after entering Royal Navy service with deeper bilge keels to alleviate a propensity to roll during moderate and heavy seas.

It involved the installation of a new MSI Defence DS-25 Seahawk AUTSIG mount with M242 Bushmaster 25mm naval gun, a new Fire Control System and Radamec's 1500 Series electro-optical tracking system (EOTS), Raytheon gyro compass, Sperry Marine Naval BridgeMaster E Series Surface Search Radar, GPS, anemometer, and EM logs.

[16][17] The Phase 2 is the Marine Engineering Upgrade Program, which includes the repair and remediation of the hull, overhaul and improvement of the Main Propulsion including control and monitoring systems, electrical plant, auxiliary systems, outfitting and hull furnishings and training the navy crew in the operation and maintenance of the new plant.
