Land-based air power would not automatically exclude Soviet carriers

Would German land-based strike aircraft make Soviet carriers unusable against the Kriegsmarine and Arctic convoy routes?

No. They would be a serious threat, but British Mediterranean experience and northern Norway's sparse, difficult-to-supply air bases show that carrier operations could remain viable.

The objection is that German land-based strike aircraft would make Soviet carrier operations against the Kriegsmarine impossible. Royal Navy carriers still operated successfully under land-based air threat in the Mediterranean despite losses and damage. Northern Norway offered fewer bases and harsher supply conditions, so German aviation could not exert the same pressure everywhere. Geography and logistical reach determine how effectively land-based aircraft can pressure carriers, while the Soviet ships would still face serious danger.
