JANUS, the Standard Underwater Language

Posted on by

NATO has announced,

The NATO Science and Technology Organization’s Centre for Maritime Research and Experimentation has developed a standard for underwater acoustic communications called JANUS, which is recognised as a NATO standard by all NATO Allies since 24 March 2017. This marks the first time that a digital underwater communication protocol has been acknowledged at international level and opens the way to develop many exciting underwater communication applications.

I think this might become important to us. It is not just a military system.

Thanks to EagleSpeak for bringing this to my attention. 

“SNA 2017 Surface Navy Association Day 3 – Part 2/2”–NavyRecognition

This is one of a series of videos from NavyRecognition discussing sponsors’ presentations at the Surface Navy Symposium. This one includes:

  • Extended Range Harpoon from 00:20 to 02:45
  • SeaRAM launcher from 02:45 to 05:15
  • RAM Block 2 from 05:15 to 5:45
  • Lockheed Martin export Multi Mission Surface Combatant 5:45 to 7:00
  • Curtis-Wright towed sonar (TRAPS) 7:00 to 08:30
  • Atlas North America SeaCat AUV 08:30 to 10:54

The things I found interesting were:

  • The growing use of SeaRAM, which has been being fitted to the trimaran Independence Class LCS, has replaced Phalanx on some destroyers and will replace the Mk49 RAM launcher on the mono-hull Freedom Class beginning with LCS-17. It is also expected to be fitted on the follow on LCS derived Frigate as well. If things start to get tense we may see these on NSCs and OPCs as well.
  • The fact that the extended range RAM Block 2 is now operational. The SeaRAM has the same degree of autonomy as Phalanx but because it is a “fire and forget” missile, will be able to engage multiple incoming anti-ship missiles at extended range.
  • More info on the Curtis-Wright TRAPS containerized active passive towed array which should be able to fit on anything WMEC sized and larger.
