How an Allied Norway constricts German Atlantic access

Holding Norway gives Allied aircraft a cross-North Sea barrier that makes German submarine transit to French Atlantic bases slower, riskier, and easier to detect.

Question

How much would an Allied victory in Norway weaken the Battle of the Atlantic?

Short answer

It could weaken it dramatically by turning the North Sea into an Allied air barrier between German yards and French Atlantic bases.

Notes

An Allied Norway would sharply restrict Germany's routes into the Atlantic even if France still fell. Radar-equipped patrol aircraft operating between Britain and Norway could force U-boats to make long submerged transits through the North Sea, sacrificing speed and endurance. Moving dismantled submarines by rail to French ports would be an awkward alternative, making victory in Norway a potentially war-shortening strategic success.
