The first rule for American submarines spying on the Russians in the Arctic is don’t get stuck in ice when going up for fresh air.
And this is what precisely a US Seawolf submarine did, went up and got completely stuck in Arctic ice, which according to CNN and the NYT shouldn’t be there.
So who came to help? The Russians dispatched an MI8 Helicopter to observe the situation, was able to locate it quickly thanks to a red flare the US sub coughed up next to it.
We are certainly not experts in the espionage game, but we will go ahead and classify the spying activities of this particular US sub as unsuccessful.
