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.
