Philippine Navy’s Frigate Acquisition Project

The Philippine Navy ordered a class of two multi-mission capable frigates from South Korean shipbuilding company Hyundai Heavy Industries (HHI), under the Frigate Acquisition Project (FAP), which is aimed at protecting the country’s territorial waters.

The Philippine Navy ordered a class of two multi-mission capable frigates from South Korean shipbuilding company Hyundai Heavy Industries (HHI), under the Frigate Acquisition Project (FAP), which is aimed at protecting the country’s territorial waters.

To be built based on the Incheon/FFX-I/HDF-3000-type multi-purpose frigate of the Republic of Korea Navy (RoKN), the vessels will offer increased operational performance and enhanced survivability.

The first steel for the lead ship (hull no P159) was cut in May 2018, with delivery scheduled for the second half of 2020. The second frigate (hull no P160) is expected to enter the construction phase in September 2018, while delivery is scheduled for the first half of 2021.

Philippine Navy’s Frigate Acquisition Project details

The decision memorandum for the procurement of two missile-capable frigates under the Frigate Acquisition Project was issued in October 2015. HHI was selected as the lowest bidder with a bid price of PHP15.75bn ($338.8m) in June 2016.

The Department of National Defense (DND) of the Republic of the Philippines signed a contract with HHI to build two light frigates in October 2016.

The mission capabilities of the frigates include anti-air warfare (AAW), anti-surface warfare (ASuW), anti-submarine warfare (ASW) and electronic warfare.

Design and features of the Philippine Navy’s future frigates

The vessel’s hull and superstructures will be built using marine-grade high-tensile metal to provide superior seakeeping ability. The ship will be 107m-long and 12m-wide and will have a displacement of 2,600t.

The frigate will be designed with stealth characteristics to reduce its radar cross-section and infrared signature.

“The vessels will feature Safran Electronics & Defense’s PASEO NS (Naval System) electro-optical fire control system for surveillance, target designation and fire control.”

It will have a 21.8m-long and 13.5m-wide flight deck towards the stern with the ability to handle one maritime helicopter weighing up to 12t. A hangar will also be fitted to accommodate the helicopter.

Two rigid-hulled inflatable boats (RHIB) will be carried to conduct military and emergency operations at sea.

An integrated navigation bridge, featuring communication consoles and multi-function bridge radar displays, will be installed to provide maritime surveillance, monitoring and manoeuvre control.

The auxiliary equipment on-board the vessel will include a fire-fighting, air-conditioning, and nuclear, biological and chemical (NBC) protection system.

Armament

Each frigate will be armed with an Oto Melara 76mm gun as a primary weapon and an Aselsan SMASH 30mm remote-controlled stabilised naval gun as a secondary weapon.

An eight-cell vertical launching system (VLS) will be installed at the forward section to defeat hostile threats.

The frigates will be equipped with Systems Engineering and Assessment (SEA) lightweight torpedo launcher systems (TLS), which can launch US Mk 44, Mk 46 and Mk 54 type torpedoes.

The vessels will also carry weapons systems, including two anti-air missiles, two anti-surface missiles, close-in weapon system (CIWS), decoy launching systems, and four .50 calibre heavy machine guns.

Sensors / radars

The Philippine Navy’s multi-mission frigates will be equipped with Kelvin Hughes’ SharpEye navigation radars, which operate in I and E/F bands to provide Doppler navigation and situational awareness.

The vessels will feature Safran Electronics & Defense’s PASEO NS (Naval System) electro-optical fire control system for surveillance, target designation and fire control in both day and night conditions. They will also incorporate a modern combat management system to control the on-board sensors and armament.

Other sensors to be installed in the vessels include fire control radar, search radar, electronic countermeasures suite, tactical communication link, a differential global positioning system (DGPS), and a magnetic compass. It also includes a speed log, electronic chart display and information system (ECDIS), automatic identification system (AIS), hull-mounted sonar, VHF/UHF radios, and other navigational aids.

Propulsion and performance of the Philippine Navy’s future frigates

The Philippine Navy’s future frigates will be powered by a combined diesel and diesel (CODAD) propulsion system, comprising four diesel engines and up to three diesel generators.

An Integrated Platform Management System (IPMS) developed by Servowatch will be installed in the frigates to monitor all power modules, including the propulsion unit, electric power plant and auxiliary / ancillary system.

The IPMS features battle damage control system (BDCS) and on-board training system (OBTS).

The vessel will have a maximum speed of 25k, can travel to a distance of 4,500nm at cruising speed of 15k and can sustain operational presence for 30 days. It will be able to withstand rough sea conditions up to Sea State 5 in the Philippines.
