The sub's still lost. Doubt is growing whether Saturday's fragmentary radio signals had anything to do with the sub.
The US Navy says that it has sent four small undersea robots (unmanned underwater vehicles) with side-scan sonars used to scan and image the ocean floor. These are operated by a newly formed unit at Pearl Harbor in Hawaii. (They look like the things that were being used to look for the Malaysian airliner west of Australia.)

The rescue crews should be there or will be arriving tomorrow. But they can't rescue the crew of the sub if nobody knows where the sub is.
