Ep 3. World's Greatest Submarine

Impossible Engineering is a popular television series which airs on the Discovery Channel, covering the world's most complex engineering projects. Season 10, episode 3 is entitled 'World's Greatest Submarine', and is a fascinating dive into the history and engineering of some of the most impressive submarines ever constructed.

The episode begins with a brief history of submarines, dating back to the 16th century when Dutch inventor Cornelius Drebbel created one of the first known submersibles. From there, the show fast forwards to the present day, zeroing in on the largest and most sophisticated submarines ever built.

The episode delves into the modern-day Russian submarine, the Akula, which is able to achieve speeds of up to 35 miles per hour and disappear completely from enemy radar. The Akula is one of several modern submarines outfitted with advanced stealth technology, which makes them virtually undetectable through a combination of low noise levels and materials that deflect sonar.

The episode also profiles the Kilo submarine, another Russian sub that weighs in at roughly 4,000 tons and can remain submerged for up to 45 days at a time. The Kilo is an amazingly silent submarine which enables it to carry out covert missions while never being detected. Its advanced torpedo technology also makes it a formidable vessel in battle.

Other submarines featured in the episode include the British nuclear submarine, the HMS Astute, which is equipped with the latest weapons technology, including Tomahawk missiles, and can operate for months without needing to refuel. We also meet the French Barracuda, which incorporates a unique air-independent propulsion system that lets it remain submerged for weeks at a time without needing to come to the surface.

Throughout the episode, we hear from a diverse group of individuals who have played a key role in the construction and operation of these imposing underwater vessels. The show provides an in-depth look at the engineering advancements that have made these submarines incredible stealth killers and advanced warfare machines.

Impossible Engineering season 10, episode 3 provides an unprecedented perspective on some of the most impressive submarines in the world. The show highlights the incredible engineering that has gone into these submarines over the years, as well as the expertise and technology that has enabled them to stay completely hidden for weeks on end. It's an informative and engaging episode that's sure to satisfy the curiosity of anyone interested in the world of naval engineering and technology. With interviews from experts and stunning visuals, the episode is a must-watch for those interested in advanced technology and engineering processes.
