Towed Array News Today

Thales Australia and Ocius Technologies have entered a Teaming Agreement to advance the development and deployment of a scalable USV capability.

The disruption, which occurred on one of two fiberoptic cables, could prove disastrous as it means there is now only one connection between mainland Norway and Svalbard with no backup.

Military intelligence officials believe Russia has developed technology, such as the Yantar, which carries remotely operated submarines equipped with hydraulic cutters.

U.s. military. >> are they just right now hoping they have a hail mary and theyre going to find something, is that what theyre about to do? >> no, i think they still -- as tom mentioned, they trust the mrsat data. they just got the look over the entire arc and theyre starting. >> is there anything else they need down here if theyre going in this whole area? the underwater search, that goes very, very slowly. think about somebody walking along all of the state of indiana, how long that could take...

There now looking? >> it does the same thing as far as collecting sonar images. but it is a towed array. meaning you have to let it out on a cable. and if its three miles deep, its going to have to let over ten miles of cable out to get to the bottom and tow it. >> so it can get stuck on things? >> if the terrain down there is rough, it doesnt view the bottom as well. it doesnt contour to the bottom where the auv will stay with the bottom and get you much better imagery. and it does have trade-o...

Peter, they are two-thirds of the way through this relatively modest search for the bluefin-21. lets say in the next few days, two or three days it should be wrapped up. they come up with nothing. no piece of wreckage, no black box, nothing. what do they do then? >> they go back to the drawing boards to see if their initial calculations identifying this area were correct and secondly they start to reach out for different equipment. probably a towed array that will help them monitor and look at t...

Length, you have to do it with a towed array. you have to do it with a new vehicle. and you better start lining that up now. >> i assume theyve searched a much wider area on the surface with the planes and the ships, right? >> thats proven negative, so they found nothing from doing that. again with looking at a wider area of search, theyre assuming that its in this area, not just on the pings, but also the fact of how much fuel they think that plane consumed based on their guess at altitude, the...

Looked at them, theyve tried to tune them so they can detect the frequency of what the pinger should emit. the first thing. the second thing is they operate deep enough. almost 300 meters, maybe deeper, and are able to provide that good link to a better acoustic channel away from the noise of the surface. the only problem with them is they really are a narrow area search tool. when you think about it, youve got to drop sonobuoys near something youre interested, you think exists in the water. rig...

>> like a drone, or towed along on a sled. we call that a towed array. and we havent gone to that phase yet, because we havent had that initial starting point. >> what happens when the batteries for those flight data recorders, the cockpit voice recorder, are dead, and the pingers -- the pinging is no longer going? where do the investigators, the search operation go from there? >> well, you see each day that the search area is shifting around. and thats because data thats being gathered from the...
