Sub Snoops for the Future

This month’s issue of the Navy League’s Seapower Magazine has a special report on an autonomous web of underwater robots that the Navy hopes will be operational by 2015. The Office of Naval Research-led project will imbue “underwater vehicles with the ability to sense and independently adapt to everything from ocean currents to hostile enemy subs.”

ONR chief Rear Admiral William Landay said, “If we can sense that, get the vehicles to understand that, get the vehicles to adapt to that, then they are in the position where they really are starting to dominate the battlespace.”

This net has been labeled “PLUSNet” and, the article explains, is comprised of a “variety of autonomous underwater vehicles and sensor technologies":

Seahorse: A platform that can easily drift while maintaining a sensing mode. Will be equipped with a high-frequency billboard sensor array on its port and starboard {left and right to you landlubbers} sides for maximum coverage.

Bluefin-21: Uses a buoyancy engine to allow drifting and bottoming modes of operation. Combines acoustic sensing capability with mobility to allow adaptive search behaviors under autonomous and supervised control.

Seaglider: An energy-efficient glider for environmental sampling while functioning as PLUSNet’s communications backbone. When a glider receives an urgent acoustic message, Seaglider will alter its flight profile to rapidly surface and transmit ashore.

Slocum Glider: A long-range deep ocean glider designed to cruise in a vertical saw tooth plane, the Slocum Glider will employ an acoustic towed array, enhance adaptive environmental sampling and sensing, and will support network communications.

X-Ray Glider: The world’s largest underwater glider, it will offer a higher speed and greater load-carrying capacity than existing gliders, boasting acoustics and electric filed sensors, along with acoustic and satellite communications capabilities.

Check out more stuff at the Navy League’s site. (And join even . . .)

Mise well put a pitot tube on a submarine!What about the guys who manage them, are they going to
be scuba qual'd? HAHAA

Why not just load up some methane gas in a bubble and ignite it, then blend it up through a high powered fan blade, the ship or sub floating or traveling over it will go down like a rock. the high intensity heat will rip little holes all over the sides of the ships making it impossible to re-weld the hulls. A little pipe on the surface of the sea bed floor could make it to where alternate gliders are not necessary at all. Missles would be obolete also because if a ship or sub got too far in on the grid of pipes realays and fans then if they fired a mine or torpedo they would set themseves off in a tidal wave of doom sinking their own ships and fleets in that area as well. How much is natural gas going for these days. .32 cents per how much in cubic square feet? It's a cheaper alternative to keep the borders of international waters and beachheads vs manned patrols or robotics patrols.
