A curious mini-sub in the news again

So in the past week, this bad boy caused a stir in California’s Monterey Bay:

Via KSBW

Some were concerned it was a narco-sub or possibly a spy boat or something, as there aren’t a lot of privately owned manned submersibles in circulation. Turns out, it is noting nefarious and is part of a crowdfunded Community Submarines project to get people into man-in-the-sea activities, which is admirable.

As for the boat itself, currently dubbed Noctiluca, it is the old British-built U.S. Submarines S-101, a 32-foot, two-person diesel-electric mini-submersible with a decent performance (range of 200 miles when surfaced, can dive for 72 hrs, 300+ foot operating depth/1250 ft. crush depth due to its 10 mm thick A43 steel pressure hull) built back in 1987.

If she looks familiar, she was used on a contract for the Royal Swedish Navy through the 1990s to serve as an OPFOR of sorts for that country’s coastal forces, mimicking Russian frogmen boats.

Then, in 1998, the Sea Shepherds (Whale Wars) guys picked it up cheap ($225K) from a Norwegian seller and, given a killer whale-style scheme, was intended to harass various fishing enterprises.

Passing into private hands in 2004, it has been up for sale off and on, most recently in Florida for about $80K.

It even showed up in a 2013 episode (S01E06) of the snorable cop show Graceland on the USA network:

Either way, nice to see it still poking around.

Showing off the Proteus mini-sub packing heat

Huntington Ingalls Industries announced a couple weeks ago that Proteus, their 26-foot-long dual-mode undersea vehicle (UUV), successfully completed autonomous contested battlespace missions during the 2017 Advanced Naval Technology Exercise (ANTX) at the Naval Surface Warfare Center in Panama City Division.

And released this sweet image:

The Panama City News Herald has more images, including shots of the interior and control panel and underway.

As noted by the PCB NH:

Since entering the testing phase in 2012, Proteus has logged 2,000 dive hours locally and abroad, including at Naval Surface Warfare Center Panama City Division (NSWC PCD), the scientific lab for Naval Support Activity Panama City.

It can go underwater with or without a human crew, though it isn’t yet being used in field missions. At ANTX, hosted by NSWC PCD, its designers showed off another capability, having Proteus carry other vehicles during testing.

Baltic Midget Submarines ahoy!

This thing is downright cute

So there is this privately owned U-boat in Germany built as part of the Euronaut project and honestly its kinda bad-ass. Its 53-feet long, 32-tons in displacement, capable of diving to 250m (500m crush depth), able to submerge for a week. Powered by a 190hp Diesel on the surface that enables it to make a blistering 8-knots for 250nm or as long as its 250 gallons of diesel let her. Submerged, 107 batteries power a 55hp electric motor allowing her to make 5 knots under the waves.

Check out the plans for this. Somewhere in North Korea a naval engineer is salivating...

She comes complete with a wet/dry chamber to lock out divers which is always handy in a tiny sub.  She was built by German engineer Carsten Standfuss over a 12 year period. She can carry 3-8 crew/divers.

So far they have used it to find the wrecks of the HMS Seahorse, HMS E-16, SMS Wacht, S.M. UC-71, an unidentified small cargo ship, a RAF Lancaster bomber, and an East German Air Force Mig-17.

Blowing!

There seems to be some sort of civilian midget submarine arms race in the Baltic. Besides the Euronaut boat, in nearby Denmark the 59-foot ‘Art project” UC-3 Nautilus, built for $200,000 and manned by former Royal Danish Navy submariners, has been called (tongue in cheek) the world’s smallest ballistic missile submarine for her recent work in launching offshore sub-orbital rockets.

Yes, thats a rocket, the 36-foot long HEAT 1X Tycho Brahe on a platform (called Sputnik) pushed by the Danish art-project submarine UC3

Either of these craft are likely still far and away better than those operated by the DPRK and Iran.
