The Indian Navy showcased its enhanced submarine rescue skills during Pacific Reach 2025 Exercise (XPR-25). Hosted by the Republic of Singapore Navy from 15 to 25 September 2025, the exercise involved over 40 nations. India’s Submarine Rescue Unit (East) embarked on INS Nistar and executed multiple successful rescue operations. This marked a key milestone in India’s submarine rescue journey and global maritime cooperation.
Exercise Overview and Significance
Pacific Reach 2025 was a multinational submarine rescue exercise held in two phases. The shore phase in Singapore included professional exchanges and an international medical symposium. The sea phase took place in the South China Sea and involved live rescue drills. The exercise aimed to enhance interoperability and readiness for real-world submarine emergencies.
India’s Submarine Rescue Achievements
India’s Deep Submergence Rescue Vehicle (DSRV) Tiger X performed three successful matings with foreign submarines over three days. These included the Republic of Korea Navy’s Shin Dol-Seok (S-082) and the Republic of Singapore Navy’s RSS Invincible. Notably, the Tiger X conducted its first dive outside the Indian Ocean Region. This achievement placed India among the leading nations in global submarine rescue operations.
Multinational Three-Asset Rescue Drill
On 25 September, a historic multinational three-asset rescue drill (R3) was conducted for the first time in Pacific Reach history. INS Nistar played a central role by localising and surveying a distressed submarine. Subsequently, India’s remotely operated vehicle and DSRV were deployed. The rescue vehicle achieved successful mating within an hour. This drill demonstrated India’s rapid deployment and operational efficiency in complex rescue scenarios.
Technological and Professional Excellence
The Indian Navy’s performance brought into light its advanced technological capabilities and high professionalism. The use of DSRV Tiger X and remotely operated vehicles showed India’s commitment to adopting modern rescue technologies. Participation in XPR-25 also reinforced India’s commitment to international submarine safety and maritime security cooperation.
Strategic and Diplomatic Impact
India’s active role in XPR-25 strengthened ties with over 40 participating navies. The exercise enhanced India’s interoperability with global maritime forces. It also signalled India’s growing strategic presence beyond the Indian Ocean Region. This engagement boosts India’s image as a responsible and capable maritime power in the Indo-Pacific.
