Indian Opinion Analysis

The commissioning of INS Nistar marks an notable step forward in India’s defense capabilities, strengthening its capacity for underwater rescue missions. With advanced technological capabilities like saturation diving systems going down to considerable depths alongside remotely operated vehicles enabling salvage work at extreme distances, this vessel signals India’s growing self-reliance. Its use as a Mother Ship further elevates its strategic importance as it can assist submarines during emergencies-a critical capability given recent growth in underwater defense assets globally.

Moreover, indigenous components amounting to approximately three-fourths reflect progress under policies like Make in India. This vessel aligns closely with long-term goals aiming at enhancing domestic shipbuilding expertise while contributing toward achieving maritime security objectives. However, continued efforts need evaluation over how thes local innovations compare internationally across cost-effectiveness metrics and operational reliability benchmarks moving ahead.
