The Indian Navy demonstrated global submarine rescue capability during Exercise Pacific Reach (XPR-25), which was hosted by the Republic of Singapore Navy (RSN), the Ministry of Defence (MoD) said in a statement on Wednesday.
"Over three successive days, the unit achieved three successful matings with international submarines, demonstrating the full spectrum of intervention and rescue operations and establishing India's position in the global submarine rescue arena," the MoD underlined.
The exercise, held in two phases, with the shore phase being conducted between 15-20 September and the sea phase taking place from 21 to 25 September.
During the shore phase, professional exchanges and an international medical symposium allowed India to present its Deep Submergence Rescue Vehicle (DSRV) system philosophy and post-rescue medical preparedness, the statement added.
"The sea phase in the South China Sea witnessed landmark achievements. On 23 Sep 2025, the Indian DSRV Tiger X undertook its maiden dive outside the Indian Ocean Region, achieving a historic first mating with ROK Navy's Submarine Shin Dol-SeokS-082). The Indian DSRV achieved another milestone by mating with RSN's submarine RSS Invincible," it highlighted.
It is worth mentioning that the Indian Navy is the only blue water force in South Asia that operates both conventional and nuclear submarines.
India's latest nuclear-powered ballistic missile submarine, INS Aridhaman, is expected to be commissioned into service by the end of this year.
