Submarine-launched Tomahawk cruise missile. Photo courtesy U.S. Department of Defense Tomahawk cruise missiles frequently appear in the news because they are the U.S. weapon of choice for a variety of quick-strike operations. With all of the missiles in the U.S. arsenal, have you ever ...
How Do You Get Air on a Submarine? A submarine has access hatches to bring in outside air when in port, and a snorkel mast to bring in air while submerged at periscope depth. Once submerged below periscope depth, equipment continuously clears the air of contaminant and oxygen-generating equi...
The crew of a nuclear submarine reveal how they stay safe during a fire. Later, the science behind the world's most advanced crash test dummies and a multi-million dollar greenhouse that provides produce year-round are explored. You May Also Like How It's Made: Dream CarsTVPG • Science...

A blimp or airship controls its buoyancy in the air much like a submarine does in the water. The ballonets act like ballast tanks holding "heavy" air. When the blimp takes off, the pilot vents air from the ballonets through the air valves. The helium makes the blimp positively buoyant ...
To operate, pneumatic and hydraulic engines must transport bulky tubes of compressed fluids, which often only last for a while. The Plongeur, the first submarine to be mechanically powered, was constructed in France between 1860 and 1863. It used a reciprocating air engine fed by 23 tanks at...

amazed and perhaps a bit shocked. Hampshire clarifies what worked and what did not. The utilization of the RN’s submarine force was particularly effective as well as the surface towed sonar arrays—perhaps the best the world had to offer at the time. Again, his appreciation of the human di...
