India, Sri Lanka Navies Hold SLINEX-25 Sea Drills

On 17th August 2025, the sea phase of the twelfth edition of the Sri Lanka–India Naval Exercise (SLINEX-25) commenced, in western waters off Colombo, with warships from both nations participating in complex maritime operations.

The exercise involves two Indian Navy ships—fleet tanker INS Jyoti and destroyer INS Rana—operating alongside Sri Lanka Navy’s SLNS Vijayabahu and SLNS Sayura in a demonstration of growing maritime cooperation.
Over the next two days, the participating warships will carry out high-intensity naval manoeuvres, including Visit, Board, Search and Seizure (VBSS) operations, gunnery drills, and coordinated screening exercises designed to enhance interoperability.
Vertical replenishment, fuelling approaches, and flashing exercises are part of the agenda, enabling the two navies to practice seamless logistical support and maritime sustainment during prolonged operations at sea.
The ongoing sea phase follows a three-day harbour phase conducted at Colombo Port from August 14 to 16, which served as a preparatory and confidence-building stage for both sides.
During the harbour phase, operational teams engaged in structured joint briefings on communications and security protocols, while also sharing best practices for maritime operations in the Indian Ocean region.
