BRP Diego Silang (FFG-7) is the second ship of the Miguel Malvar-class guided missile frigates of the Philippine Navy. She is the second ship to be named after Diego Silang y Andaya, a Filipino revolutionary leader who fought against Spanish colonial rule.
The warship was delivered to the Philippine Navy on 9 September 2025, and entered active service following commissioning on 2 December 2025.
The BRP Diego Silang was designed and built by HD Hyundai Heavy Industries (HD HHI) of South Korea, and is based on the shipbuilder's HDC/HDF-3200 design, which in turn was a re-designed and enlarged HDF-2600 design used for the Jose Rizal-class frigate already in service with the Philippine Navy. The design was heavily influenced by the base design of the Incheon-class frigate built for the Republic of Korea Navy, but with heavy design developments and features found on newer frigates of the R.O.K. Navy, considering reduced radar cross-section by having cleaner lines, smooth surface design, reduced overhangs and a low free-board.
The First Steel Cutting Ceremony was held on 22 November 2023 at HD HHI's facility in Ulsan, South Korea. Her keel was laid on 14 June 2024, a few days before the launching of her sistership BRP Miguel Malvar (FF-06). She was launched in December 2024.
In March 2026, the ship participated in the Royal Australian Navy's Exercise Kakadu Fleet Review on Sydney Harbour.
