The Royal Navy is moving away from crewed mine hunting to a mixed capability involving a host platform and autonomous support vessels.

They're exploring the possibility of deploying more underwater autonomous vehicles to help with this search. meanwhile, overnight, the bluefin-21 exploring new depths. it traveled some 4.7 kilometers underneath the ocean's surface. previously thought it could only travel 4.5. now, it's very important that it's able to go into deeper t waters. you may remember it had cut its first mission short. this is really critical area. it's the area they believe that most likely find the black box based on that very detailed acoustic analysis of pings. so it's a good sign it was able to go deeper into the...

Those batteries of the black box pinger have completely expired. the question now being when exactly are they going to feel comfortable to make that assumption and deploy the underwater autonomous vehicle to find the physical wreckage, isha. >> 37 days into the search for flight 370. erin mclaughlin there in perth, thank you, erin. not much is known about the seabed in the southern indian ocean. it's one of the most remote places in the world. in fact, it's said we know more about the surface of the moon and of mars than we do about the bottom of our oceans here on earth. tom foreman looks a...

I think they'll probably give it a go a few more days because the minute you start using that blue fin device, the underwater autonomous vehicle that has the sonar, everything slows down so dramatically. six times slower to cover the same, you know, piece of turf in the ocean. and so they want to just run this to ground, if you will. and then begin that process, but it's just going to be a very slow and for the families excruciating process. >> excruciating indeed, because to hear one expert put it earlier, said to cover a 100-square-mile area it may span five months' time and we're talking wi...

But it's worth saying that the "hms echo" has sophisticated sound-detecting equipment, but it's also capable of mapping the sea floor. officials here in australia are not commenting on this development in the search at the moment, but not saying whether or not this might signal perhaps a new stage of this search. for all we know, as you say, the "ocean shield" is currently out there, equipped with that american towed pinger locator, scouring the waters, trying to detect more signals from this black box pinger. and angus houston, who's the man, the chief coordinator behind this multinational se...
