🇵🇭 Philippines
South China Sea · Multi-Purpose Port
Subic Bay in Philippines sits along the most heavily contested waters on Earth. More than one-third of global shipping — roughly $3.4 trillion in annual trade — passes through the South China Sea, with overlapping territorial claims from China, Vietnam, the Philippines, Malaysia, Brunei, and Taiwan. China's artificial-island construction in the Spratly and Paracel archipelagos has expanded the operational reach of its coast guard and maritime militia, both of which have been documented harassing commercial vessels near disputed features. Piracy and armed robbery persist in the southern reaches, particularly between Malaysia, Indonesia, and the Philippines. Typhoon season (June–November) adds significant schedule and fuel uncertainty for voyages routed through the region.
Routed sea distances from Subic Bay to the principal global hubs, computed by ArcNautical's routing engine — around land and through the canals a ship actually uses, not great-circle.
No port-call data observed at Subic Bay in the last 180 days. This reflects the reach of the terrestrial AIS network behind this page — coverage is densest in Northwest Europe and thins elsewhere — and is not a statement about traffic at Subic Bay.
Subic Bay falls under the Tokyo MoU. The Tokyo Memorandum of Understanding (Asia-Pacific) maintains the most active publicly-available regional PSC programme. Across the last 24 months, the Tokyo MoU detention dataset records 5,509 distinct vessel detentions (sourced from OpenSanctions, as of 2026-09-06). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
