Indian Navy’s Secret Nuclear Submarine Base – INS Varsha

India’s strategic naval project, INS Varsha, an underground base for nuclear submarines, is under construction near the coastal village Rambilli in Andhra Pradesh, about 70 km from the Vishakhapatnam base. Operated by the Eastern Naval Command headquartered in Visakhapatnam, this cutting-edge naval base on India’s east coast will serve as a key point in the Bay of Bengal.

The base’s construction involves extensive engineering efforts, including the creation of numerous tunnels into a mountain, large piers, and support facilities.  While the exact cost is unknown, estimates suggest it will reach $3.75 billion.

Crown Jewel Of Eastern Naval Command

INS Varsha – nuclear submarine base’s proximity to the Bhabha Atomic Research Centre (BARC), India’s primary nuclear research facility associated with its nuclear weapons program, indicates Rambilli’s suitability as a clandestine naval base site. The location was chosen for its unique underground chambers, which enable submarines to enter and exit the base through tunnels without surfacing and avoid detection by enemy spy satellites. This ensures the covert deployment of India’s nuclear submarines.

INS Varsha will house repair and maintenance facilities and amenities for crew rest. Its size will accommodate large nuclear submarines like the Arihant class, the upcoming S5, and nuclear attack submarines.

Creating A New Naval Hub Near Visakhapatnam

Visakhapatnam, home to the Headquarters of the Eastern Naval Command, serves as a base for over 50 warships of the Indian Navy, utilizing its landlocked natural harbor as an ideal position for naval operations. However, the current Visakhapatnam port often encounters congestion due to heavy civilian container traffic and visiting ships. In response, the establishment of INS Varsha seeks to offer specialized infrastructure and amenities tailored to naval needs, aiming to reduce interruptions from commercial port operations.

By segregating naval activities from civilian maritime traffic, this new base will bolster the Navy’s operational efficiency and preparedness in the area.
