Hyundai Heavy Industries Offers HDF-3500 Frigate To The Philippine Navy

In the ever-evolving landscape of maritime defense, the need for advanced and adaptable naval capabilities has never been more critical. At the forefront of these developments is the recent announcement by South Korean shipbuilder HD Hyundai Heavy Industries (HD HHI) during the Asia Defense and Security (ADAS) 2024 exhibition, where the company confirmed its proposal to offer the HDF-3500 frigate design to fulfill the Philippine Navy’s Frigate (Full Complement) Acquisition Project, commonly referred to as Frigate Phase 2. This project is part of the Re-Horizon 3 phase of the Revised Armed Forces of the Philippines Modernization Program (RAFPMP). Given the strategic implications of this offering, it is essential to evaluate the HDF-3500's design, capabilities, and potential alignment with the Philippine Navy's operational needs.

The HDF-3500 is classified as a 3,500-ton frigate, with a length of 129 meters, situating it comfortably between the existing fleet's capabilities and future needs. This size marks a significant upgrade from the Miguel Malvar-class corvettes, which utilize the HDC-3200 design, and the Jose Rizal-class frigates that utilize the HDF-2600 design. The HDF-3500's dimensions provide an optimal balance between maneuverability and firepower, allowing for enhanced operational versatility.

However, the HDF-3500 is also notably smaller than the HDF-3800, another model speculated by Defense PH, which raises the question: what strategic considerations influenced HD HHI's decision to propose this specific design? It is likely that the selection underscores a tactical philosophy of providing a well-rounded vessel capable of addressing both current and anticipated maritime security challenges.

One of the standout features of the HDF-3500, as presented through the scale model at ADAS 2024, is its considerably advanced armament. The frigate is equipped with a 76mm Oto Melara Super Rapid gun, which offers a robust and reliable naval artillery capability. Additionally, the frigate's armament includes a 16-cell Vertical Launching System (VLS) designed for VL MICA NG air defense missiles, positioning the vessel to effectively counter aerial threats.

Moreover, the inclusion of an 8-cell launcher for anti-ship missiles—most likely the LIG Nex1's C-Star—demonstrates a dual capability to address both surface and aerial threats, enhancing the frigate's role in projecting power and ensuring maritime security. The Aselsan Gokdeniz Close-In Weapon System (CWS) further reinforces its defensive posture, providing layered defense against anti-ship missiles and other close-range threats. Additionally, the presence of two triple torpedo tubes underscores the vessel's versatility in anti-submarine warfare operations.
