Why not sonar then?

  If you mean "why aren't they using sonar to locate the missing vessel", I'm sure they're trying. One of the articles about this event I saw mentioned a P-8 Poseidon being deployed to assist the search. I would be extremely surprised if at least a few sonobouys hadn't been deployed. If you're asking why they don't have a acoustic phone for underwater communications, I couldn't tell you. As I understand the Janus digital underwater communications standard (which as I understand is an open standard and is also standardised as NATO STANAG 4748, so search vessels should be able to understand it) range is about 28km [1], not sure about purely analogue implementations, but some solution should be easily achievable for any entity capable of building the submarine in the first place. Maybe they simply elected not to install one? or maybe the sub is drifting and the search area is too large to reliably establish communications. They seem to have a "move fast and break things" approach and declined to get their vessel "classed" [2] as they claim to be too innovative to follow industry standards for such things... does not bode well for the missing vessel.

    Makes more sense. I believe they were skimping on the necessary safety measurements.
