Description
Description | The Indian Navy is designing the upcoming Project-77 nuclear-powered attack submarines (SSNs) and Project-76 next-generation conventional submarines (SSKs) using a shared foundation of sensors, subsystems, and combat architectures to build a robust, interconnected underwater fleet. The initiative includes a domestically developed Combat Management System (CMS), identical multi-function displays, non-penetrating optronic masts, shared electronic warfare packages, and uniform Integrated Sonar System (ISS). Both classes will be constructed using specialised high-tensile steel such as HY-130 grade engineered by MIDHANI. The goal is to maximise indigenous content, reduce reliance on foreign vendors, and simplify crew training and maintenance. |
