They were steam powered (they had turbines) It took theat long to smouther the bolier fires and to stow and seal the funnels. Yous can see this was not a good class of subs to be on. Many were lost through collision, either with there sister subs or destroyers when on training cruisers. Some were lost when the funnel seal failed and flooded the boat.
Even when it dived it was no fun, with all the hot machinery taking a long time to cool. It would start to make you long for the trenches of France!
