Replacing the Subs

[Colin Parkinson]

Operating under the ice needs to be defined. I suspect it means travelling a short distance under the ice edge. Our subs will not be transiting under the ice.
The power plant doesn’t determine if you can punch thru the ice. The amount of reserve buoyancy is what determines if it can push up thru the ice. The type and thickness of the ice needs to be factored in as well. As well, the structural strength is a consideration.
I’m sure there are some submariners on this forum whom could better explain this.

We can test the new subs under ice performance, by having a icebreaker follow them in an exercise. There will be no modification to the sail for punching through the ice, so likley if they have to, they will be stuck on the surface till they get back to base for repairs.

I safely say we won't be surfacing through a ice pack. At least not intentionally. At most we'll be operating ice edge around the marginal ice zone and after much study and precautions.
