INS Mumbai is delivering essential spares, support, and equipment for Sri Lanka’s Dornier maritime surveillance aircraft
In a significant demonstration of naval diplomacy, the Indian Navy’s frontline destroyer, INS Mumbai, docked at Colombo port in Sri Lanka on Monday, August 26, for a three-day visit.
 
The visit of INS Mumbai, a 163-meter-long Delhi-class destroyer, is notable for several reasons. This is the destroyer's first visit to Sri Lanka, and it marks the eighth visit by an Indian ship to the island nation this year. The ship, commanded by Captain Sandeep Kumar and manned by a crew of 410 members, was welcomed by the Sri Lankan Navy in accordance with naval traditions. 
 
INS Mumbai is in Colombo primarily to deliver essential spares, support, and equipment for the Sri Lankan Air Force’s (SLAF) Dornier maritime surveillance aircraft. The aircraft provides a unique and critical capability of surveillance over the Sea Area of Responsibility (AOR) of Sri Lanka since induction two years ago.
 
The Dornier aircraft is operated and maintained with significant assistance from India. In addition to training the SLAF pilots and flight navigators, the Indian Navy is supporting the maintenance of this aircraft with a technical team and spares. Earlier this year, INS Kabra and later ICGS Sachet had brought spares parts for Sri Lanka Coast Guard ship Suraksha.
 
Enhancing Interoperability & Coordination 
During its stay in Colombo, the crew of INS Mumbai has engaged in various joint activities with their Sri Lankan counterparts, aimed at enhancing interoperability and strengthening bilateral ties. These activities included a range of community engagement events, such as yoga sessions, beach cleaning drives, and sports fixtures, which foster goodwill and camaraderie between the two navies.
 
A significant component of INS Mumbai’s visit will be a Passage Exercise (PASSEX) with a Sri Lankan Navy ship, scheduled to take place off the coast of Colombo upon the destroyer’s departure on August 29. PASSEX exercises are routine naval drills that enhance tactical communication and coordination between navies, further solidifying operational ties.
 
A detailed briefing on the operational capabilities and functions of INS Mumbai was conducted for Sri Lankan naval personnel. This exchange of knowledge and expertise is part of the broader defence cooperation between the two nations, which has seen India playing a crucial role in bolstering Sri Lanka’s maritime security.
 
According to the Indian High Commission in Sri Lanka, it has been customary for Indian Naval Ships to make port calls at Sri Lankan ports, when transiting between Arabian sea and Bay of Bengal. The visit is categorized as an Operational Turn Around (OTR), wherein the ship will also replenish fuel and provisions.
 
The timing of INS Mumbai’s visit to Sri Lanka is particularly significant in the context of India’s strategic interests in the Indian Ocean Region (IOR). The Indian Navy has been increasingly active in the region, conducting numerous naval exercises, port visits, and joint patrols with regional partners to ensure a stable and secure maritime environment.
 
The ongoing naval cooperation between India and Sri Lanka, exemplified by the support provided for the Dornier aircraft and the planned PASSEX, highlights India’s commitment to being a steadfast partner for its southern neighbour. As the Indian Ocean continues to be a critical arena for geopolitical competition, such naval engagements will play a crucial role in shaping the security architecture of the region.
 
India’s proactive naval diplomacy, as demonstrated by the visit of INS Mumbai, reflects its broader strategic objective of ensuring peace, stability, and security in the Indian Ocean Region, even as it navigates the complexities of regional competition with China.
