Other meanings of Piracy in the Sulu and Celebes Seas
Maritime security
Piracy in the Sulu and Celebes Seas refers to acts of armed robbery and hijacking committed against vessels in the maritime region bounded by the Philippines, Malaysia, and Indonesia. This area has been a notorious hub of piracy for centuries, and modern incidents—often involving the kidnapping of crew for ransom—continue to threaten regional security and shipping routes.
The Sulu and Celebes Seas have been a corridor for piracy since at least the 14th century, when the Sulu Sultanate controlled the waters and relied on raiding for slaves and goods. European colonial powers, notably Spain and the Netherlands, struggled to suppress these raids, which continued into the 19th century. The Moro pirates of the southern Philippines became infamous for their swift, well-armed vessels, known as barangay or pangayaw.1 After the colonial era, piracy declined but never disappeared, resurfacing in the 1990s with the rise of separatist and criminal groups.
Since 2000, piracy in the Sulu and Celebes Seas has shifted from cargo theft to kidnapping for ransom, often targeting crew of tugboats, barges, and fishing vessels. The Abu Sayyaf Group, a militant Islamist organization based in the Sulu archipelago, has been a primary perpetrator, claiming responsibility for high-profile abductions. In 2016, the International Maritime Bureau (IMB) designated the region as a high-risk area, leading to the formation of the trilateral Maritime Patrol (MALINDO) by Indonesia, Malaysia, and the Philippines.2 Despite these efforts, attacks persist, with an estimated 20–30 incidents annually, many unreported.
Beyond the headline kidnappings, piracy in the Sulu and Celebes Seas has deeper socio-economic roots. Many perpetrators are former fishermen who lost their livelihoods due to overfishing and restrictive maritime boundaries. The region's complex geography—thousands of small islands, treacherous currents, and porous borders—makes law enforcement extremely difficult. Environmental damage from illegal fishing also fuels the cycle of criminality. Another obscure dimension is the historical role of the sarmat, a traditional longboat used by Sulu pirates, whose design influenced modern patrol vessels. Additionally, some piracy incidents are known to involve women as lookouts or negotiators, a fact often overlooked in mainstream accounts.
Trilateral patrols through the MALINDO initiative have reduced the number of successful attacks, but coordination remains weak due to national sovereignty concerns and limited resources.2 The Philippines and Malaysia disagree on maritime boundaries, complicating joint operations. Regional navies have also deployed maritime domain awareness systems, including radar and satellite monitoring, but these are expensive and not always effective in the dense island environment. The Eyes in the Sky program, launched in 2017, uses aerial surveillance to track suspicious vessels, yet pirates adapt by using smaller, faster boats.
