Last i year, during a motorbike convoy to Indonesia, i went to Surabaya to visit the Monumen Kapalselam (Submarine Monument). The monument actually is a real submarine known as KRI Pasopati 410. The Indonesia already got their own submarine in 1960.

KRI Pasopati is Whiskey Class Submarine made in Russia and saw active duty in 1962 but never saw any battle action during her duty including the time of Confrontation with Malaysia.

The ship can carry about 64 crew members.
My first experience with submarine was in 1998 in Langkawi, French Agosta. The living quater is small and crew sleep in the torpedo room.
