Upside Down Landing Craft Utility (LCU2) is a deep wreck dive in outer Subic Bay where the landing craft lies inverted on sand, with its broken sections, supports, and shadowed gaps now working as an artificial reef. The shape is less about a clean silhouette and more about exploring the underside contours, fish-filled recesses, and hard growth that has taken over the metal. Divers usually visit it by boat as an advanced wreck dive because the depth leaves little margin for a slow descent or long bottom time. Even when visibility is typical Subic green rather than crystal clear, the structure holds plenty to inspect, from macro life tucked into the metalwork to schools of fish hanging under the hull and around the adjacent reef line.
