We often think of submarines as fairly complex pieces of machinery, and for good reason. Keeping the electronics watertight can naturally be quite difficult, and maintaining neutral buoyancy while traveling underwater is a considerable engineering challenge. But it turns out that if you’re willing to skip out on those fairly …read more

The British government is investing up to £2.5 million (US$3.2 million) to begin the development of an extra-large autonomous submarine for the Royal Navy. Measuring 30 m (100 ft) in length, which is larger than the Boeing Orca eXtra Large Unmanned Und… Continue reading Royal Navy to develop 100-foot long unmanned robotic submarines
All through the cold war, there was a high-stakes game of cat and mouse in play. Nuclear powers like the United States and the Soviet Union would hide submarines armed with nuclear missiles underwater. The other side would try to know where they were so they could be targeted in …read more

Submarines are universally considered cool, but bring several challenges to the RC modeller that aren’t there with land and air builds. Water ingress can ruin your project, and there’s always the possibility of it sinking to the bottom, never to return. That didn’t phase [Brick Experiment Channel], however, and thus …read more
France has launched the first of its six next-generation nuclear attack submarines in a ceremony in Cherbourg. On July 12, 2019, President of the French Republic Emmanuel Macron presided over the unveiling of SNA Suffren before a crowd of con… Continue reading France launches its first Barracuda class nuclear attack submarine
Omega Watches reveals that when American explorer Victor Vescovo broke the record for the world’s deepest manned submersible dive, his craft set another record by having three Omega Seamaster Planet Ocean Ultra Deep Professional wrist watches… Continue reading Omega sets record for the deepest diving watch
It is fun to make a toy vehicle with Lego, but it is even more fun to make one that actually works. [PeterSripol] made two Lego submarines, and you can see them in the video below. There isn’t a lot of build information, but watching the subs fire missiles and …read more

It’s entirely possible that micro-machines could one day be delivering drugs inside the body, with many designs proposed in recent years. The latest comes from the University of New South Wales (UNSW), which gets around under its own power us… Continue reading Self-powered micro-submarines sink and swim to deliver drugs in the body
Setting a bottle adrift with a message in it is, by most measures, an act of desperation. The sea regularly swats mighty ships to their doom, so what chance would a tiny glass bottle have bobbing along the surface, subject as it is to wind, waves, and current? Little to none, it would seem, unless you skew the odds a bit with a wave-powered undersea glider to the help the bottle along.
Before anyone gets too worked up about this, [Rulof Maker]’s “Sea Glider” is about a low-tech as a device with moving parts can be. This craft, built from …read more

By the early 20th century, naval warfare was undergoing drastic technological changes. Ships were getting better and faster engines and were being outfitted with wireless communications, while naval aviation was coming into its own. The most dramatic changes were taking place below the surface of the ocean, though, as brave men stuffed themselves into steel tubes designed to sink and, usually, surface, and to attack by stealth and cunning rather than brute force. The submarine was becoming a major part of the world’s navies, albeit a feared and hated one.
For as much animosity as there was between sailors of …read more
