He also develops tactics for a periscope-free torpedo attack, despite the skepticism of colleagues and management. And now, when the Happy "Pike" had to take on board the crew of another Soviet submarine, and she was on the seabed with almost no oxygen, Aleksei manages to save people and perform the operation, paying for it with his life...
