I want to know the answer to the following question:
Which oceans did the sub base provide access to?
All the background I'm provided with is that "In addition, the Soviets provided Germany with access to the Northern Sea Route for both cargo ships and raiders (though only the commerce raider Komet used the route before the German invasion), which forced Britain to protect sea lanes in both the Atlantic and the Pacific.". Is that enough to answer the question?
Answer: yes
