It was awesome! I was taking a course at UBC studying Canadian foreign policy in its entirety with professor Allan Craigie. We were able to go on a field trip to check out the naval base in Esquimalt, British Columbia!
By far the coolest thing was standing next to a active torpedo and being in a landing bay where special forces scuba dive in and out of the submarine while underwater! The Living quarters where super cramped, and solidified my existing belief I would not be able to handle submarine life. But the crew members do get to play video games and socialize so there is that.
Looking through the periscope was pretty cool though! Definitely if you get the chance take it and check out a sub!
