Описание: Every US Navy nuclear submarine eventually runs out of fuel—and replacing a reactor buried deep inside a pressurized steel warship is one of the most complex engineering operations on Earth. In this video, we break down how the Navy cuts open submarines worth billions of dollars, removes entire sections of interior structure to access the reactor core, and rebuilds them from the inside out—a process that takes up to 4 years, costs over $2 billion, and requires more than a million man-hours of skilled labor to keep America's aging submarine fleet operational for decades longer.
