Project 627 actually looks like a giant torpedo when it's out of the water. Its lenght far exceeds the other dimensions. Its bow, however has a proper drop shape. There aren't many shots of November class submarines in drydock, not even after the fall the USSR when they went to the scrap yard. This is the best I could find:
Notice the bulge under the bow. The first vessels in the class lacked this dome which housed a huge cylinder that is the sonar "antenna".
No wonder the XXI shape was so popular. It was designed using water tunnels, so it was extensively tested through trial and error. Possibly the most elegant offspring of this design was the Project 651 juliett
