BRP Antonio Luna (FF-151). BRP Antonio Luna (FF-151) is the second ship of the  of guided missile frigates in service with the Philippine Navy. She is able to conduct multi-role operations such anti-surface warfare (ASUW), anti-submarine warfare (ASW), and limited anti-air warfare (AAW). She is one of the service's primary warships until the introduction of new and more powerful contemporaries.

Construction and design
The BRP Antonio Luna was designed and built by Hyundai Heavy Industries (HHI) of South Korea, and is based on the shipbuilder's HDF-2600 design, which in turn was derived from the  of the Republic of Korea Navy (ROK Navy). Changes were made on the base design by making use of design developments and features found on newer frigates of the ROK Navy, considering reduced radar cross-section by having cleaner lines, smooth surface design, reduced overhangs and a low freeboard.

On September 17, 2018, the steel cutting ceremony was held for P160 (project number of second of two frigates) at HHI shipyard at the Shin Hwa Tech facility in Pohang City, South Korea, marking the first step of the ship's construction journey. On December 20, Lorenzana announced at a press conference the names of the two future frigates being built by HHI: BRP Jose Rizal and BRP Antonio Luna.

On May 23, 2019, HHI held the keel laying ceremony for P160 at HHI shipyard, marking the formal start of the construction of the ship. In the press briefing the same day, a Hanwha official said that Link 16 will likely not be compatible for the frigates until 2020 because of issues between US and South Korea. On November 8, HHI launched the second ship, the prospective BRP Antonio Luna, at Ulsan shipyard in South Korea.

The ship's outfitting, sea trials and delivery were affected by restrictions due to the COVID-19 pandemic. HHI conducted sea trials to test the ship's seaworthiness, propulsion, communications, weapons and sensor systems.

On December 18, 2020, the Philippine Navy's Technical Inspection and Acceptance Committee declared that the ship is compliant with the agreed technical specifications after witnessing its sea trials. This paved way for the frigate re-docking and final outfitting before delivery.

On January 29, 2021, the prospective BRP Antonio Luna (FF-151) was approved for delivery and acceptance by a joint Department of National Defense and Philippine Navy inspection team. On February 9, the ship was met by  in the vicinity of Capones Island, Zambales after leaving South Korea four days ago. This was complemented by a fly-by of three FA-50 light fighter jets from the Philippine Air Force. On March 19, the ship was officially commissioned as BRP Antonio Luna (FF-151). The ceremony happened at 8 o`clock in the morning at Pier 13, South Harbor, Manila. It was attended by Philippine Defense Secretary Delfin Lorenzana and Philippine Navy Rear Admiral Adelius Bordado.
