#2 Naval mines are going to be pestiferous in the future. The Cold War precluded deployment of advanced systems for 50 years, and now suddenly, the technologies are in catch-up mode.

Though anybody's guess, many of the littoral catamaran-type ships being designed now seem to take into account this potential. And the ONR devotes a lot of research into anti-mine robotics (attn: Shipman).

One interesting technique is the use of passive torpedo-like sensors that use ocean temperature to propel themselves along. Deployed dozens at a time, they "swim" from surface to sea floor and back in a sine wave pattern. With such a passive propulsion system, they can operate for several weeks without refueling.

Several waves of these sensors could "clear" a large channel near a coastline, and might even contain a small charge to blow up any mine found.

Far more popular right now is the use of "biologicals", such as dolphins, who are talented in the detection of such things. Their only drawback is that the Navy does not like to risk their lives unless absolutely necessary.

#3 those unlikely to attack Finland

Let's see, that would be anybody but Russia, Sweden and Norway. I hope the USN gets a copy of the software.

#4 Those anti-mine robots not tiny 'moose. :)

#5 It also means the M2 is probably very cheap, without the expense of a lot of custom made (and developed) parts.

No expensive 12 year program life? Not in the Haliburton product line? Less than
$ 150,000,000. per copy.... FORGET IT!

#6 (detecting the sound of the target ship), pressure (detecting the pressure on the water a ship over head makes), and magnetic (detecting the metal in a ship) sensors

*AHEM* WW II mines did this on a regular basis, ie. droped by aircraft, programed to count and sink last ship in a convoy slipping thru a harbor channel, and thereby blocking the rest of ships in harbor. [sitting ducks]

us old farts were perfect, you young wippersnappers!

#7 everyone well italians for sure have that kind of mines

#8 Well, Shipman, if you remember, I suggested using small, floating robotic mines to deny a major sea lane to a floatilla of less advanced ships, such as in an invasion of Taiwan. The only "must have" in the design is that they don't detonate when they bump into each other.

While such mini-mines wouldn't impact a warship, they could perhaps punch a 3" hole below the waterline in a civilian ship being used for military purposes, either seriously slowing it down or maybe sinking it.

Other ideas I suggested were that the mines be able to "swim", not just float, either to space themselves out, or two swim in the direction of a mine explosion--not to attack the same target, but to fill the gap left in its wake.

Lastly, and for larger mines, I suggested that they be designed as the body of a UAV, that would fly to its destination, then drop in the water to tear off its wings. Which is a quick way to deploy mines without risking a ship.

What you found this suggestion either hilarious or profoundly disturbing, I have no idea.

#9 'moose the part that always tickels me is the... "thousands of tiny robots", it's not even the concept, it the weird rhythm of the words.

#10 Instead of using UAVs tho,I'd breed special Brown Pelicans with built in anti-amphibious logic. They would carry the mines internally and instinctively attack amphibious shipping by homing in on the galley trail.

Or thousands of tiny robots.... :>

#11 The Perfect Bottom Mine

Am I the only one who thought this was going to be an article about Boy George's favorite new nightclub?

#12 Kind of the Anacin and Bufferin "thousands of tiny time pills" thing? Meh, some like one...

On the plus side, the TOTR concept is definitely on the drawing board, and not just at DARPA and ONR. I suppose that it just seemed reasonable to tailor AI after insects and other simpler swarming critters. Real-world applications are harder to imagine, but they exist.

#13 Shipman, hadn't your Golden Retriever a while back gotten the teensiest bit impatient with your thousands of tiny robots obsession? ;-)
