US Navy - Extreme Technology - War Submarines - Unbeatable Experience

At 171 metres long, the #USS #Pennsylvania is the biggest #submarine in the #US Navy. It can dive deeper than a thousand feet, sail for 20 years without #refuelling, and remain #submerged for up to 6 months. The vessel carries a #crew of 155 men and a #deadly #nuclear arsenal. The film investigates how this submarine was made possible through a series of six #historic #engineering breakthroughs. We explore the inner workings of six landmark submarines, including the tiny Turtle and colossal #German U-Boats. Each features a major #technological innovation that allowed engineers to build bigger #submarines, including the development of #underwater #breathing, #torpedo’s, #missile launch systems, and stealth technology. Using computer-generated imagery this film reveals the incredible stories behind these machines and the inventions that have allowed them to grow in size. Six ingenious leaps forward enabling submarines to evolve, from BIG, to BIGGER, into the US Navy’s BIGGEST.
