The Navy’s Kilo-class submarine INS Sindhuratna which underwent a major upgrade in Russia reached Mumbai after sailing for 97 days and almost 10,000 miles with two port calls in between.
The submarine underwent a Medium Refit Life Certification (MRLC) process in Russia which extended its life. However, it faced transportation issues in the backdrop of the war in Ukraine.
The initial plan was to move it by a transport dock ship directly from Russia which did not materialise following which the Navy tried to sea transport the submarine to Norway and then via a transport dock to India which also did not materialise. Following this, the Navy decided to sail it directly on its own.
