Why an ice-capable SSBN changes deployment choices

Ice reinforcement is favoured because it gives an SSBN more deployment areas and makes patrol locations less predictable.

Question

Would an SSBN force in an undeclined Royal Navy still be reinforced for ice?

Short answer

Yes, because ice capability increases the choice of deployment areas and supports less predictable patrol locations.

Notes

In the hypothetical larger Royal Navy, ice reinforcement is endorsed for ballistic-missile submarines. The reason given is the wider choice of places in which they could deploy. Unpredictable patrol locations are treated as a useful part of SSBN operations.
