One of the most interesting things I have seen in my life is INS KURSURA submarine museum. It is at the R.K. Beach road and after reaching Visakhapatnam you can easily go to this museum by buses or auto.INS KURSURA took part in 1971 Indo - Pak war and was decommissioned from Indian Navy in 2001 and then govt. decided to keep it as a museum.
After entering into the submarine some people may feel suffocation as it is very narrow inside. There will be a guide inside the museum who tells all about the history and parts of the submarine.
You will realize that it’s very difficult to survive inside and you will feel proud of our soldiers who remain inside the submarine for months, to protect us and our nation.
