GS Paper 2 (Internal Security International Relations) GS Paper 3 (Security Challenges)

What Happened

  • Indian Navy warship INS Trikand responded to a distress call from merchant vessel MV Golden Arsenal in the Gulf of Aden, thwarting a suspected piracy attempt.
  • The warship's prompt presence caused suspected pirates to flee before they could board the vessel; no crew members were injured.
  • Indian Marine Commandos (MARCOS) were subsequently deployed to board and secure MV Golden Arsenal, which was carrying critical cargo bound for India.
  • The operation is part of the Indian Navy's continuous anti-piracy deployment in the Gulf of Aden, which has been active since 2008.
  • In 2026, Somali piracy has re-emerged as a material threat to commercial shipping in the Indian Ocean Region, with hijackings and offshore attacks increasing.

UNCLOS Framework for Anti-Piracy Operations

The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982 and entering into force in 1994, is the primary international legal framework governing maritime activity, including piracy. Article 101 of UNCLOS defines piracy as illegal acts of violence, detention, or depredation committed for private ends by a private ship against another ship on the high seas. Article 105 grants all states universal jurisdiction to seize pirate ships and arrest pirates on the high seas — meaning any country's navy can act against pirates regardless of the pirates' nationality or the flag of the victim vessel. Article 100 obliges all states to cooperate fully in repressing piracy.

  • UNCLOS Article 101: defines piracy — must occur on the high seas, involve two ships, and be committed for private ends.
  • UNCLOS Article 105: universal jurisdiction — any state may seize pirate ships and prosecute pirates on the high seas.
  • UNCLOS Article 100: all states have a duty to cooperate in repressing piracy.
  • The Gulf of Aden is high seas (beyond any nation's 12 nautical mile territorial sea), so Indian Navy operations there are fully compliant with Article 105 jurisdiction.
  • India ratified UNCLOS in 1995.

Connection to this news: INS Trikand's response to MV Golden Arsenal's distress call and MARCOS' boarding operation are legally grounded in UNCLOS Articles 100–105, which authorise universal jurisdiction anti-piracy action on the high seas. The Indian Navy does not require flag-state permission to act in such scenarios.

Indian Navy's Continuous Anti-Piracy Deployment (2008–present)

Since 2008, the Indian Navy has maintained a continuous anti-piracy deployment in the Gulf of Aden and the Western Indian Ocean as part of the international response to Somali piracy. This is one of the longest uninterrupted operational deployments in the Indian Navy's post-independence history. The deployment has escorted over 3,440 ships and protected more than 25,000 seafarers across approximately 106 ship deployments. Operation Sankalp (launched June 2019) is a related but distinct operation — focused on safe transit of Indian-flagged vessels through the Strait of Hormuz during escalating US-Iran tensions, and has since evolved to address multiple maritime threats across the Indian Ocean Region.

  • Anti-piracy deployment in Gulf of Aden: continuous since October 2008.
  • Cumulative escorts: 3,440+ ships, 25,000+ seafarers protected.
  • Operation Sankalp: launched June 19, 2019, for safe transit through the Strait of Hormuz; distinct from the Gulf of Aden anti-piracy mission.
  • In 2026, Somali piracy has re-emerged following a period of suppression (2011–2017), partly attributed to the withdrawal of international naval assets and broader instability in the Horn of Africa region.
  • India's anti-piracy engagement reflects the "SAGAR" (Security and Growth for All in the Region) doctrine announced in 2015 — India as the net security provider in the Indian Ocean.

Connection to this news: INS Trikand's Gulf of Aden deployment is a routine rotation within the Navy's 18-year-old continuous anti-piracy commitment. The incident underscores the renewed urgency of this mission as Somali piracy resurges in 2026.

MARCOS — Indian Navy Marine Commandos

MARCOS (Marine Commandos) are the special operations force of the Indian Navy, established in February 1987. They are trained for amphibious warfare, counter-terrorism, hostage rescue, anti-piracy operations, and covert reconnaissance — capable of operating at sea, in the air, and on land. MARCOS are trained in underwater demolition, combat diving, parachuting, and close-quarters combat. Their selection and training process has an attrition rate exceeding 80%, and they are regarded among the most capable special operations units in Asia. In maritime anti-piracy operations, MARCOS conduct vessel boarding, search, and seizure (VBSS) — the standard tactical procedure for securing a merchant vessel from pirates or confirming the vessel's safety.

  • Established: February 1987.
  • Parent service: Indian Navy.
  • Training: 7.5–8 months initial course; includes combat diving, parachuting, close-quarters battle, and maritime assault.
  • Role in anti-piracy: Vessel Boarding, Search and Seizure (VBSS) operations — fast-rope from helicopters or small craft onto merchant vessels.
  • Comparable international units: US Navy SEALs, UK Special Boat Service (SBS), Israeli Shayetet 13.
  • MARCOS have operated in the Gulf of Aden as part of embedded anti-piracy deployments since 2008.

Connection to this news: After INS Trikand deterred the piracy attempt on MV Golden Arsenal, MARCOS conducted a VBSS operation to board and formally clear the vessel — the standard protocol to confirm no pirates remain hidden aboard and to secure any critical cargo.
