Continental Defence Corvette

[Underway]

If a surface vessel were operating in co-operation with uuvs and neede to communicate with them would the r/t facility look like a sonar dome?

And these corvettes, are they to operate in the ice or are they just supposed to survive in the slob at the ice edge?

St. Laurence all year round is the ice thickness and type you are looking for. That's "ice edge" in the arctic as you'll bump into stuff but hopefully never need to break anything.

Has anyone thought that one through yet? Strictly from watching the series put on TV for northern freight delivery there seems to be no clear dividing line. One day they are operating at the edges in the slob as you termed it but the next day the wind has come up and they are struggling to get clear of the ice. Will an ice strengthened hull give you the safety margin or do you have to go one better and have the ability to maneuvre in at least first year ice?

The actual "ice edge" is probably a marketing term for the land lubbers. There isn't a dividing line especially as currents and wind get involved. I suspect the Corvettes will act like so many migratory animals, following the advance and retreat of the ice as it comes and goes.

I'm sure someone is discussing what that is supposed to look like but I think that St. Laurence in winter is the real target ice resistance.

I know northern trawlers that fished in Okhotsk for pollock and Baffin Bay for shrimp were taken out of the water and retrofitted with additional ribs and plate to make them fit for the ice edge. It has been a while since any boat has been trapped and crushed. Skippers tend to take weather forecasts pretty seriously.

And the slob is what the skippers called the slushy icy water that preceded the actual ice when the winds, tides and currents brought the ice down from the north into their fishing grounds off St Lawrence and the Pribilofs.

US firm could soon deliver energy wirelessly to underwater vehicles

The initiative will see NUBURU design specialized blue-laser technology for integration into SunCubes' DEEP LIGHT underwater wireless power platform.

"energy and data to travel more efficiently through underwater environments."

"Underwater laser-based power transmission system

"The project represents the first concrete application emerging from a recently signed agreement between NUBURU and SunCubes. It aims to develop an underwater laser-based power transmission system capable of delivering energy wirelessly to autonomous underwater vehicles (AUVs) and other subsea systems, potentially transforming the way underwater assets are powered and operated.

"The DEEP LIGHT platform is designed around a high-power laser transmitter and receiver architecture that enables contactless energy transfer underwater. Unlike traditional underwater charging methods that require physical docking or cable connections, the system seeks to transmit power over distances of several tens of meters using laser beams operating in the blue-green optical spectrum.

"This wavelength range is particularly important because blue and blue-green light experiences lower attenuation in water than many other wavelengths, allowing energy and data to travel more efficiently through underwater environments. By leveraging NUBURU’s expertise in blue-laser technology, the collaboration aims to improve the efficiency, reliability, and scalability of underwater wireless power systems."

A UUV would still have to approach within "10s of meters, may be a kilometer or so for data only, but it wouldn't have to surface.

And if the surface vessel were working with a swarm of similarly equipped UUVs then line of sight relay, together with actual physical displacement of the UUVs to get within communicating distance of each other, could result in near real time comms over extended distances.
