Indian Naval Ship (INS) Tarkash concluded a five-day port call at Port Louis, Mauritius, on Thursday, 5 November 2026, marking another milestone in the deepening maritime partnership between India and Mauritius. The visit, part of INS Tarkash's operational deployment to the southern Indian Ocean Region, featured cross-training exercises, leadership interactions, and community outreach activities ahead of its departure.
Key Activities During the Harbour Phase
INS Tarkash arrived at Port Louis on 30 October 2026 and spent the harbour phase conducting a range of bilateral engagements. Cross-training exercises with Mauritius Coast Guard personnel, leadership-level interactions, and community outreach formed the core of the visit. A cultural exchange programme was held to commemorate Aapravasi Diwas 2026, a Mauritian national observance honouring the arrival of indentured labourers on the island — underscoring the shared historical and cultural ties between the two nations.
Joint EEZ Surveillance and PASSEX on Departure
Upon departing Port Louis, INS Tarkash undertook joint Exclusive Economic Zone (EEZ) surveillance with a Mauritius Coast Guard Dornier aircraft. The ship also conducted a PASSEX — a passing exercise — with CGS Valiant, the Mauritius Coast Guard vessel. Such exercises enhance interoperability and are a standard feature of India's maritime engagement with Indian Ocean littoral states. An Indian Navy spokesperson posted on X: 'Orevwar, Moris! Until we meet again, Mauritius! INS Tarkash concluded a memorable port call at Port Louis, Mauritius. The harbour phase featured cross-training engagements, leadership interactions, community outreach activities and a cultural exchange commemorating Aapravasi Diwas 2026.'
Backdrop: Admiral Swaminathan's August Visit
The port call builds on a high-level visit in August 2026, when Chief of Naval Staff Admiral Krishna Swaminathan travelled to Mauritius and called on Prime Minister Navinchandra Ramgoolam. During those talks, Admiral Swaminathan pledged 'full support, assistance, cooperation and collaboration' of the Indian Navy towards the capability enhancement and capacity building of the Mauritius Police Force and National Coast Guard. He also met Rampersad Sooroojebally, Commissioner of Police, and Kan Oye Fong Weng-Poorun, Secretary for Home and Defence Affairs, as well as the Indian High Commissioner in Mauritius.
India-Mauritius Maritime Partnership: Broader Context
The Indian Navy described India and Mauritius as sharing 'an enduring maritime partnership, anchored in mutual trust and a shared commitment to ensuring a secure and stable Indian Ocean Region' — explicitly linking the engagement to the vision of MAHASAGAR, India's framework for maritime cooperation with Indian Ocean neighbours. Notably, the visit's emphasis on joint EEZ surveillance reflects growing concerns over illegal fishing, drug trafficking, and non-traditional security threats in the southern Indian Ocean. This is consistent with India's broader strategic posture of positioning itself as a 'net security provider' in the region. The convergence of naval visits, high-level diplomatic engagements, and operational exercises signals that the India-Mauritius maritime axis is being steadily institutionalised.
Point of View
Not just episodically conduct, maritime engagement with Indian Ocean island states. The MAHASAGAR framing and the follow-through from Admiral Swaminathan's August visit suggest India is tightening its security architecture around Mauritius as competition for Indian Ocean influence intensifies. What bears watching is whether these operational linkages translate into tangible outcomes: shared real-time domain awareness, permanent liaison arrangements, or joint patrol protocols — rather than recurring goodwill visits that look impressive on paper but lack operational depth.
