The Space Gal: Onboard a Nuclear Submarine follows Emily Calandrelli aboard the USS Oregon for a behind-the-scenes look at how a nuclear attack submarine works. The video explains key engineering and physical science concepts, including nuclear propulsion, diesel backup engines, torpedo tubes, life-support systems, carbon dioxide scrubbers, oxygen generation, waste disposal, and why submarines can stay submerged for long periods. It also introduces nautical operations such as diving, surfacing, and “angles and dangles,” while connecting submarine systems to space technology and the International Space Station. With strong links to STEM, engineering design, military technology, and U.S. naval history, this overview supports curriculum topics in physical science, technology, transportation systems, and career exploration.
