India's indigenous AIP system for diesel-electric submarines achieves a significant milestone with the inauguration of the 'Setting to Work Phase-2' activity

Historic Day for the Indian Navy as a Major Milestone in Indigenous Technology and Defense Capability Achieved

The Indian Navy has marked a historic day by achieving a significant milestone that showcases the country’s defense capability and indigenous technological mastery. A revolutionary change has occurred in the construction and testing process of the indigenous AIP (Air‑Independent Propulsion) system being developed for the Navy’s diesel‑electric submarines. In this context, the “Setting to Work Phase‑2” activity has been inaugurated, considered one of the most important steps toward the final transformation and operational readiness of this system.

The AIP system is a lifeline that enhances the submarines’ telecommunications capability and stealth, as it enables submarines to receive power and propulsion while remaining submerged, without surfacing for extended periods. Indigenous development of this system not only reduces dependence on imported weapons but also strengthens the world‑class reputation of Indian military technology. The inauguration of “Setting to Work Phase‑2” proved to be a decisive turning point in this process, allowing engineers and technicians to establish communication among all sub‑systems, prepare for initial testing, and identify potential defects.

Senior Navy officials have described this achievement as a symbol of coordination and innovation among the country’s defense establishments. At this stage, a comprehensive assessment of the latest technical features of the AIP plant will be conducted, covering energy efficiency, compliance with safety standards, and reliability during long‑term operation. According to experts, after the successful completion of “Setting to Work Phase‑2,” the next phase will involve full‑load testing and preparation for series production, which will serve as an initial platform for the Indian Navy’s next‑generation submarines.

This achievement underscores the impressive results of the Make‑in‑India movement in the Indian defense sector. The operational deployment of the indigenous AIP system will not only significantly enhance the functionality of the Indian Navy’s submarine fleet but also give a new dimension to India’s technological self‑reliance in the region. With the inauguration of this activity, military experts have expressed hope that in the coming years this system will place Indian submarines among the world’s most modern and stealthy submarines, thereby bringing positive changes to regional security equations. This technological leap by the Indian Navy is the ultimate symbol of the country’s defense infrastructure resilience and technical proficiency.
